NERP^2 = Hardware: From Concept to Retail && PiAQ: Indoor Air Quality Sensor


Next Monday at NERP we’ll have a double feature. We’ll hear part 2, of Ste and Nicks’s story of adventure in bringing a successful consumer product to market. Part 1 was about technology, and part 2 is about the _business_ side of bootstrapping HD Retrovision ( Also on Monday, Dave Conroy will tell us about the PiAQ Open Source Indoor Air Quality Sensor for the Raspberry Pi (


About HD Retrovision:
Nick and Ste have been friends since 1999 and both share a passion for playing the (now retro) video game systems that they grew up on. Since then they’ve both studied Electrical Engineering at University, and are now business partners in a company called HD Retrovision that is dedicated to improving the modern day experience with retro consoles while making it accessible to as many people as possible. In this presentation, Ste and Nick will walk you through the ups, downs, and lessons learned while taking a college project and turning it into a profitable company. This talk will cover how they took the idea for HD Retrovision’s Genesis and SNES cables out of the lab, got it funded, and eventually mass-produced overseas.

About the PiAQ: As an R&D Engineer for NAR’s Center for REALTOR® Technology & CRT Labs, Dave Conroy investigates emerging technologies, educates NAR members & the public through presentations, webinars, blogs and podcasts, and develops products for use by members. He’s presented to REALTORS® on the national, state and local levels. The PiAQ is an open hardware and software indoor air quality sensor developed by the National Association of REALTORS’ CRT Labs. The goal for this project is to make information about the air people are breathing more accessible.

Flying Halloween Skull – Update!

Last year, I put together a skull to fly around my yard (some Halloween folks will recognize this system as an “Axworthy Flying Ghost“). The system was comprised of two Adafruit Neopixel rings for eyes, attached to a styrofoam skull, which had been hollowed out. Inside it, was an Arduino Uno, Adafruit AudioFX board, a 314mhz receiver, a 3-watt Class-D amplifier, a custom-made interface board which tied all the previously-listed components together, and a LIPO battery.  The idea was that I could remotely trigger the skull to play one of four sound effects. However, all those parts sure weighed a lot, which when combined with the span between my pulleys, really made the skull sag down low.

This year, I decided to KISS.  I ripped out all the guts, except for the Neopixel eyes. I decided that this year, I’m not going to have sound in the skull. Instead of the Uno, I went with an Adafruit Trinket, and used a UBEC (Universal Battery Eliminator Circuit) to drop the LIPO voltage from 7.4V -> 5V that the Trinket and Neopixels run at. Shown below is how everything is connected together, prices, and sources if you’d like to make your own! And here’s a video of what the eyes look like (sorry about the VVS!!)!

Bluth Family Stair Car – PPPRS

For the Power Racing Series event at Maker Faire Detroit we decided to rebuild Duck, which was rebuilt from Noah Way, into something new. We decided on the Bluth Family Stair Car because we love Arrested Development and because Jim added it to the list of cars that get extra Moxie points.


The photo above served as our reference image when we were building the body for the car. We didn’t really make any modifications to the frame of the car, and it remained largely what it was when it raced a Make Faire Kansas City in June.


This is what we ended up with. The entire body, paint job, etc. was done in about two nights right before we left for Detroit. (This is typical of build a PPPRS vehicle at Milwaukee Makerspace, and sometimes referred to as a “Rage Build”). Oh, while Ed, Kathy, and various other helpers worked on the car itself (electronics, mechanicals, etc.) I focused on the body, because I tend to fall back on my design skills when others jump into the areas they know way more about than I do…


We started out with a bunch of Coroplast (aka “corrugated plastic”) sheets that Kathy brought in, and I created a “box” from which to cut away the unwanted parts, leaving us what would ultimately be the Stair Car. I also took this opportunity to learn all about pop rivets and how they work (and don’t work) and most of the body is held together with pop rivets, washers, and gaff tape.


Pieces have been cut away, and it looks more Stair Car-ish, and started to get a paint job. I should note that Shane and Carl pitched in here with the body, and helped out tremendously.


Meanwhile, over at the vinyl cutter… With a degree in Graphic Design, this is where I get nerdy, and try to replicate things exactly (as time allows) so yeah, I had to find the graphic, convert it to vector, cut the vinyl mask…


…and cut the other vinyl mask, and get things ready for painting. Weeding vinyl is so much fun, why not do it twice!? Yeah, I ended up redoing the whole thing because I used paint that did not stick to plastic. Argh! No worries, practice makes perfect!


I may have made a huge mistake, but it turned out fine in the end. I made another sign for the other side while Shane was making car door windows and a front grill with headlights.


Oh yeah, at some point Ed added another motor so that the car now had front wheel drive via the bicycle hub motor, and one-side rear wheel drive from some motor and controller we had laying around the space.


Some pieces ready for painting, and the soon-to-be Stair Car in the background, awaiting the Banana-worthy upgrade.


Ready for Detroit! I mean, as ready as we could get it with just a few nights working on it until 3:15am or so. It still looks like a bike inside of a box but if you squint real hard… Stair Car!

(At this point I should also note that while no number appears on the “real” Stair Car, the number 40 added to ours does use the font from the opening titles of the television show. Because again, I’m a design nerd.)


The front view is less Stair Car-like, but luckily Karen at the space helped Kathy make an awesome Banana-helmet attachment that really cements the deal. Solid as a rock!


I ran out of time (and steam, which is bad, because I’m powered by steam) and didn’t get to do anything excellent with the back of the car (like add a set of detachable stairs) so it just says “There’s Always Money in the Banana Stand” (though I should have changed “Money” to “Moxie”, oh well.)


The side view is much better than the front or back, which makes sense, but that doesn’t stop race fans young and old from enjoying the Stair Car and shouting out “Go Banana Go!” when they see it pass the slowest cars on the track.


Stay Tuned for the further adventures of Stair Car… With it placing 11th in the season standings for 2016 and one more race left it ain’t over yet!

Shelfs and Brackets


This project encompasses the two areas that I know the most here in our makerspace.  The Aluminium brackets were made in our metal shop while the Walnut and Ash shelfs where built in the Wood shop.  This project was my first attempt at making dove tail joints.  First the ash and walnut were plained to thickness and glued together.  Then I cut the glued up boards to length.  The longest step in the process was setting up the dove tail joint.  After watching hours of youtube videos between test cuts with the router and dovetail jig I managed to get a passable joint.


Once the shelfs were made it was on to the metal shop to machine the brackets.  The aluminum block was first put in our lathe to make round.  Then each piece was cut up into the half moon pieces and milled on the Bridgeport.

Because wedding insanity is real

When my husband and I started planning our wedding earlier this year, we wanted to make sure we got to spend time with all of our family members who were traveling in from out of town, many from out of state.  It was one of our many reasons for trying to have a small guest list for our intimate wedding.

Oh, and also because the wedding industry is crazy.

When I saw that the veil I wanted to go with my dress was just as expensive as the dress, I decided it wasn’t that important to me.  I saw a lot of Pinterest boards with DIY wedding veil pictures and tutorials, so I figured I would give it a shot.  If it failed, no big deal.  So, this is the story of my $15 wedding veil.


I started with some tulle that was donated to the Makerspace’s Craft Lab, and sorta followed a tutorial online.  The biggest pain was pinning the tulle folded in half, so that when I cut the rounded corners, it was even.  With Karen’s help, I used ol’ string-on-a-peg to make a partial circle cut line, which let the veil fall nicely around my head.

Using invisible thread I sewed the trim lace (bought via Etsy) to the edge of the veil.  If I were doing this again, I’d clean up the lace before sewing it on, but I did it at the end and it turned out okay.


While working, I laid the veil on a very large piece of fleece material, and also folded it up inside the fleece to keep it from sticking together (the eyelashes on the lace liked to cling to the tulle).



Take THAT, wedding industry people!!

What is the most useless thing to make on our big fancy expensive Tormach CNC machine?  How about something that most people get for free.  Something that you can find in most garbage cans on garbage day.  An item you might use every day and never think about it.  A CLOTHES HANGER.  This is quite possibly the most over engineered device for hanging a shirt or pair of pants ever made.  The hangers are cut from a 1/4 inch piece of aluminum on our Tormach CNC with a 1/4 inch end mill.  From there they are wet sanded and polished then cleaned in preparation for anodizing.  The second arm of the hanger is shaped from Black Walnut and finished in Danish Oil.  This is version 1 of the hanger and version 2 is in the works.

Soft Robotics Talk at Maker Faire by NYCR Members Kari Love and Matthew Borgatti

Headed to Maker Faire? Come see our members Kari Love and Matthew Borgatti speaking about their soft robotics work and their company Super-Releaser. They’ll be presenting “Iterating on Soft Robots: Bringing the Maker Ethic to Emerging Technology” from 1:00 to 1:30pm on Sunday at the Maker to Market Pavillion.

Here’s the description of the talk from MAKE’s site:

The emerging field of soft robotics has experimentation at its heart. Roboticists from Super-Releaser will highlight how hands-on experience in materials and fabrication informs their research. Designing flexible things takes flexible thinking and the rapid hacking makers know so well.

Sustainable & Mezzanine Funding Drive!

It’s hard to believe that we’ve been open less than 6 months, and yet ahead of our expectations (and with much relief), our membership level has just tipped 32 taking us into sustainability!! A huge expansion from the founding group of just 5.

Reaching that incredibly significant milestone is extremely satisfying, and I think I’m safe in saying we’re all proud of the community we’re developing, but the rapid growth brings a new challenge – space. We’re already starting to a feel a bit cramped on busy evenings, particularly the Wednesday open evening, so it’s time to focus on our next objective – expansion!


We’ve always known we needed a clear path for expansion, and having the room to expand with a mezzanine was a key priority in selecting a suitable property. This is by far the most cost effective way for us to expand, as we only pay rent on the ground floor area. Fortunately, our landlords approved this in principle back in Feb before we signed the lease.

So, let me take a break from prose and show you some concept visuals – first up is a simple overview of how we plan to insert the mezzanine:


Taking advantage of the high ceilings, we can gain a little under 600 sq ft replacing the current kitchenette/seating area with a wide staircase to the new floor. This also allows the remaining space above unit 34a (the inset unit) to continue to be used for storage (e.g. raw materials, WIP projects).

In terms of usage, the ground floor space can then be divided up into distinct metal/wood zones, with doors to contain dust/noise, leaving the whole of the upstairs for light crafts, socialising, etc. One option for fitting out the space is illustrated below – with green blocks indicating storage areas:

Mezz layout option

Similarly, here’s an option for dividing the ground floor into metal (left) and wood (right) zones, including room for a large format laser cutter (big pink block top-middle):


Funding the Mezzanine

Funding this project is highly dependant on how we tackle the construction labour, but taking the same approach we used for the original space fit-out, we plan to do the majority of it ourselves! This keeps the cost to an absolute minimum – focused on raw materials, building control/engineering and some essential equipment.

We will also split the build into two phases:

  1. Minimum viable product (£3k) – just the basic structural work, lighting, electrics and associated engineering/approval fees
  2. Furnishings and aesthetics (£1.5k)

Phase 1 gets us a usable space for minimum spend, into which we can move a lot of our existing furnishing. We also have enough spare raw materials to perform a basic fit-out prior to funding phase 2.

Thus, the immediate focus is on funding the £3k required for phase 1, starting with finding a structural engineer to validate/refine the plans. Given the huge desire from our existing membership to make this happen, we’ve kicked off a pledge drive to raise the £3k as fast as possible.

Pledge Drive

Rather than use a crowd funding platform, we’re keeping it simple and asking for honour-bound pledges from our existing members, supporters, enthusiasts and anyone else who would like to help make this happen.

So… you may be wondering how strong the initial response has been? Well, fairly stunning – since the pledge drive started last Friday (the 24th Sep), we’ve already received £1,250 from existing members!! and that’s just from the small group that happened to be around on Friday 🙂

If you’d like to make a pledge, please get in contact with the directors via our normal email address:

Other Funding Sources

Of course, pledges aren’t the only way to raise funds. We are also working to secure additional funding through grants, gifts (e.g. Swindon Soup) and sponsorship. As grants/gifts may take longer to secure, the plan is to progress those in parallel with the pledge drive and use them to fund phase 2.

More Info / Get Involved

There is a lot more detail and planning behind the brief introduction I’ve shared above – please get in touch if you’d like to know more or want to get hands on with the project.

Finally, we’re always grateful for any/all donations and until it’s funded, every penny will be put behind the mezzanine expansion:

Ever wonder how the world’s population increased six-fold over the past century while the number of people starving dropped?  This is in large part due to the Haber-Bosch process, the most important invention you’ve probably never heard of.  The Haber-Bosch process allows for human beings to create nitrate fertilizers using nitrogen from the atmosphere and hydrogen gas.  It’s a pretty cool trick, but it still requires the use of a lot of energy as well as fossil fuels.

In the previous post I designed a circuit which was supposed to read in when pressure was applied to a custom sensor made from velostat.

The first post on the Piano conversion

I made a sensor out of some single sided FR4 printed circuit board material, some foam tape, two pieces of wire, a small 1 cm x 1 cm piece of velostat and some sticky tape!

Custom Pressure Sensor using Velostat
This is just a prototype and may not be my final version of the sensor. I wanted to see how well velostat worked and how it would behave. It seems to work really well!

I found from measurements with my multimeter that when the pressure sensor is not touched the resistance across the wires is 30 kΩ. When pressure is applied it drops to 1 kΩ. That should be more than good enough for the purposes of detecting a key-press!

The constructed pressure sensor
Next the PCB designed in the previous post was etched, drilled and populated. It etched well and I populated it with the designed components:
The underside of the PCB, etched and populated
The populated PCB and the pressure sensor
I then wrote some quick test code for the arduino because I'm leaning towards using an arduino for the microcontroller:

Pressure Sensor test Code
For Electronic Piano
(c) A. Lang 2016


// These constants won't change. They're used to give names
// to the pins used:
const int analogInPin = A0; // Pressure Sensor connected to A0

int sensorValue = 0; // value read from the pressure sensor via the amplifier stage
float outputValue = 0; // value output to the Serial port

void setup() {
// initialize serial communications at 9600 bps:

void loop() {
// read the analog in value:
sensorValue = analogRead(analogInPin);

// print the results to the serial monitor:
Serial.print("sensor = " );

// wait 10 milliseconds before the next loop
// for the analog-to-digital converter to settle
// after the last reading:
The code is very similar to code I had written before - what is it with me and pressure sensors at the moment! I then uploaded the code to the arduino and tested it - It didn't work as planned - I may have been a little disappointed at this point....

I then thought about my circuit and looked at the schematic:
The original Key Press schematic

I realised I had made a mistake. I didn't account for how the velostat would behave in terms of it's resistance. I thought it would have a resistance of around 1 kΩ and doesn't it's resistance is 
30 kΩ and varies down from that when pressure is applied. Because of this I need to tweak my circuit from behaving as a two stage buffer to a simple analogue comparator and buffer. Luckily it won't be too hard to change things!

Here is the new circuit:

The Key Press Schematic Version 2 

The new circuits works in a similar fashion as the previous one. The velostat pressure sensor makes up a voltage divider. The output of the voltage divider is connected to an analogue comparator made with the first op-amp in an LM358 dual op-amp IC. The negative input has a 2.75 V reference set by the 8.2 kΩ resistor and the 10 kΩ resistor. The output of the 1st op-amp is then connected to a buffer amplifier with a gain of two and then the output is connected to a FET and an LED. The output will be sent to the ADC of the micro-controller which will probably be an Arduino.

To test the circuit I removed a 10 kΩ resistor and then added a 7.5 kΩ resistor (because I couldn't find an 8.2 kΩ resistor). Here is a photo of the modification:

The modified PCB
Here is the modified PCB layout although I probably won't etch this board again. I'm going to re-design it to use surface mount components and be a smaller form factor. It would be nice if each board fit snugly under each piano key.

The New Key Press Layout
I then connected the circuit back up to the arduino and pressed the sensor! It worked. The LED lit up - although I wish I had used a brighter LED...but SUCCESS!! So sweet...

Here is a graph I made from the serial monitor results. It looks very similar to the simulated oscilloscope trace from the first post!
The results from the serial monitor
So now we have a valid method of reading key presses we need to scale things up - and shrink a few things down. I will redesign the key press PCB layout to use surface mount components to take up as little room as possible. Then we need to look at multiplexing all of the signals together...and for that I'm going to use the 74HC4076 integrated circuit breakout board.

That's all for now people - take care!

NERP Tonite! Improving the Retro Gaming Experience

Ste Kulov is Lead Design Engineer at HD Retrovision. Ste (known in NBA Jam as STE) was born and raised in the suburbs of Chicago and spent most of his childhood with his hands glued to a SNES controller. Like so many life-long nerds, Ste went to school for electrical engineering and became an expert at working with circuits. His passion for working on really cool engineering projects is second only to his obsession with video games. Ste conceived the original idea for HD Retrovision in his engineering design class to solve the world’s most pressing problem: allowing gamers to play their old systems on TV’s that don’t have the right inputs. [NERP Note: HD Retrovision cables are analog circuit devices. The HD Retrovision circuit board is molded into the cable.]

PS:One knows Ste for being a really good teacher. We wish he could find time to do more analog and fpga circuit classes (hint, hint).

A vital aspect of manufacturing is testing and quality control. Someone has to do it, and they need test instruments, test fixtures, custom software, and detailed written test requirements and procedures. Ste had to design a turnkey QC system for use by his contract manufacturer. The HD retrovision circuit itself is all analog, but the QC system is FPGA based. At NERP tonite, Ste will explain how you QC a cable on the other side of the world.

NERP is not exclusively Raspberry Pi, the small computer and embedded systems interest group at Pumping Station:One in Chicago. NERP meets every other Monday at 7pm at Pumping Station:One, 3519 N. Elston Ave. in Chicago. Find NERP and Pumping Station:One at

Introduction to Arduino Workshop on Saturday, 19th November

Nottingham Hackspace will be hosting an all-day Introduction to Arduino Workshop, run by James Fowkes, John Moody, and Ian Dickinson, on Saturday, 19th November.

The Arduino system is a microcontroller board and software designed for extreme ease-of-use and learning, and has been wildly successful all over the world – not just in electronics, but for all sorts of maker projects. If you want to learn how to incorporate electronic control into your projects, this is definitely the workshop for you.

This workshop will cover:

  • What an Arduino is, and how to program it
  • Components and tools
  • Basics of electronics (voltage, current, resistance, etc.)
  • Arduino input and outputs
  • Controlling high-power components
  • Analog output
  • And more!

Aimed for complete beginners, this workshop doesn’t require you to have written a single line of code, switched on a soldering iron or even own an Arduino to take part. All the electronics equipment, including Arduino boards, will be provided on the day, but you will need to bring a laptop to program the Arduino with. It would also help if you installed the Arduino software onto your laptop before the workshop.

This workshop will run from 11am to 4pm, with a break for lunch at 1pm, and will cost £20, which includes use of all tools, boards and components, and free tea or coffee.

Arduino Unos will be available to purchase for £18 and Arduino Starter Kits will be available to purchase for £35. Please bring cash if you would like to buy either of these.

Casting Maker Faire Ingots

For the last few months Kayla has been working on casting a pile of ingots for Maker Faire Milwaukee.  These ingots are made from scrap metal donated to the Milwaukee Makerspace by its members.  Everything from Kayla’s personal favorite, hard drive casings, to parts of tools and engines.  Its really cool to see her take trash and turn it into treasure in the form of aluminum bars.

Mandolin Plates on the ShopBot

My name is Ralph, and I’m an amateur luthier and PS:1 “starving hacker”.

I make all kinds of instruments: guitars, ukuleles, bouzoukis, and more, but my favorite thing to build is mandolins.  They are far and away the most difficult instrument that I make, and require a level of craftsmanship not found in the simpler instruments.

There’s only one real downside to building mandolins— the carving.  Mandolin plates are made from 1” thick stock, carved into a very precise dome shape ranging from 3mm thick at the rim up to 6mm thick at the bridge.  Making the plate accurately is the key to getting a good tone from the instrument: too thick and it sounds “dead”, too thin and the top can’t withstand the force of the strings.

To make the plates requires a set of inside and outside templates that show the proper curves (making these templates on the laser cutter was a primary reason I joined PS:1), using carving gouges to get close the the final shape, and then curved planes and scrapers to get the dimensions exact.  There is about 40-50 hours of carving and scraping that go into a set of mandolin plates.  To make things worse, the back plate is made of hard maple, which is VERY difficult to carve.  Even with leather carving gloves, my hands are a mess of blisters and callouses after making a plate.

When I saw the CNC routers at PS:1, I was immediately struck by the idea of using CNC to produce a rough mandolin plate.  Even if I would still need to scrape to get things perfect, the hard carving work (and blisters) would be taken care of by the machine.

Thus began a year-long journey of discovery…

I learned about CAM, and taught myself to use Fusion 360, only to discover that this 3D modeling stuff is HARD.  I managed to turn out some pretty simple models for bridges and headstocks, which I was able to make on the Shapeoko and ShopBot, but every attempt at modeling a mandolin plate failed.

After flailing around for many months, I discovered the Fusion 360 meetup (sponsored by Autodesk and held at PS:1), and everything changed.  With the help of Autodesk’s Michael Aubrey (Fusion evangelist), and PS:1’s resident CAD experts, I improved my skills to the point where I was able to make a reasonable model of the top plate for an A-style mandolin.


Last weekend, I got to test the model on the ShopBot!  The initial version is in MDF, just to test the model and the machining commands.  Once everything is tweaked, I will do the real thing in Sitka spruce.

Since the plate needs to be machined on both sides, I needed to create a fixture to align everything.  It’s a pretty straightforward plate, with two alignment pegs that match holes drilled into the ShopBot wasteboard.  All of the shaping was done with a 1/2” round-nose bit running at 12000 rpm and a chip load of .35mm.

The inside is machined first, referencing the stock top.  It uses a pretty simple adaptive pocket to remove most of the waste, followed by a spiral with a 1mm overlap to take things to the finished size.


You’ll note that the pocket is not centered in the picture— my origin was in the wrong place in my model.  I fixed that, and the second attempt came out much better.  There is still a bit of scraping/sanding to remove the machine marks, but that was to be expected.


After the inside surface was machined, I flipped the workpiece over and re-registered the Z axis to the bottom of the piece.  That way, I know the thickness of the part will be accurate even if my stock thickness is off by a little bit.

Once again an adaptive pocket removed most of the stock, starting with a channel around the rim.


After the rim was rough-sized, the “hump” was roughed in.


A second pass of the adaptive pocket got the rim down to 4mm thick, and smoothed the transitions.


Just as with the inside, the finishing step used a spiral to clean the surface and eliminate the tool marks.  The net result was quite good, and will need only a bit of scraping to finish


After all was said and done I swapped in a 1/8” straight bit to cut the outer profile and f-holes.


Cutting off the excess stock left me with a quite nice-looking mandolin top plate!  Total elapsed time (not counting my initial screwup) was about 90 minutes.


Putting my micrometer to the finished product, the results were better than I expected.  Thickness is accurate within 1mm across the entire profile, with most areas within 0.5mm.  That leaves only a bit of scraping to get things perfect!

Next weekend… the real thing, in sitka spruce.

Many thanks to Michael Aubrey from Autodesk, Ray Doeksen and Andrew Carmadella from PS:1, and all of the Fusion 360 Meetup crew that helped me along the way!  I’m still a modeling rookie, but I’ve come a LONG way with your help!

Maker Faire Signs

IMG_2528 head

Over the last few weeks the Maker Faire team has been hard at work making some new signs to hang in the exhibit hall.  These signs are 10 x 5 feet and will make finding your way around much easier.  The logos are first traced on vinyl sheets and then carefully cut out.

signs 2 images

After the stencils are cut they are laid out on the fabric banner for painting.  It can be a challenge to get the curved lines of these very large logos to lay flat.  Kim, Mike, Kathy, and Pete have been doing a great job.  This project has been a labor of love for Kim who designed these signs and has seen them from drawing to fabrication.


Be sure to look for these signs and lots of others this month at the largest free Maker Faire in the US right here in Milwaukee at Wisconsin State Faire Park.  For more information about Maker Faire Milwaukee and all the amazing makers that will be there click here.

It’s Not Aliens (probably)

On May 15th of last year, a Russian radio telescope picked up a “strong signal” coming from the direction of a star known as HD 164595.


Suddenly, everyone is talking about aliens.

HD 164595 is mostly similar to our own sun, and we know it has at least one planet. And it’s reasonably close (as far as nearby stars go).

There are a lot of things this could be other than aliens trying to talk to us, such as Earth-based interference or gravitational lensing from a more distance source. So when something like this comes up, others have to be able to repeat the observation to treat it as an intentional artificial signal.

The SETI@home project makes it easy to help search for repeat observations. But even they are pretty sure that the signal isn’t of alien origin.

And now the Russian team has announced that they believe it to be a signal from Earth.

In the framework of this program, an interesting radio signal at a wavelength of 2.7 cm was detected in the direction of one of the objects (star system HD164595 in Hercules) in 2015. Subsequent processing and analysis of the signal revealed its most probable terrestrial origin.

The best speculation I’ve seen is that since the 11 GHz (2.7 cm) signal was in a band typically reserved for military purposes, they may have picked up a bit of communication from a surveillance satellite.

So no aliens. Yet.

Hackspace Manchester

We need your help!

English not your first language? Wish I’d stop waffling? You want the Simple English Version

Dearest members,

We need your help running the hackspace.

A community organisation such as HacMan doesn’t run itself, there are a lot of small behind the scenes jobs to do and quite a few big front of house ones too. One of the largest at the moment is making our new space habitable and accessible. It has become increasingly obvious that there is an expectation that that the board will orchestrate this, sadly we collectively have neither the capacity nor the time to micromanage such a large project. The board is intended solely to do the following:

  • make sure the bills are paid and that we have things like insurance
  • assist with the on boarding process for new members
  • provide a single point of contact for complaints
  • provide an abstraction layer for dealing with the landlord, utilities companies etc.

The board are of course dedicated members who donate a lot of their time and energy to the hackspace however, we are only 5 people, we cannot do everything.

At the moment there are a few dedicated members attempting to put together the hackspace and keep it operable so that you can use it. They’re not all board members but there aren’t enough of them. We really should be further on with the rebuilding of the space than we are. The hackspace belongs to all of us, please help us build it into a better community.

Specifically we need help with:

  • Accessibility: we’d love the space to be as accessible as possible for all makers however, the board are not experienced enough to judge what is and isn’t accessible. Nor are we capable of judging whether a given adaptation will fix a given issue or not. As we don’t have the experience and knowledge to allow us to make the changes some of our members, and potential members, need we’re asking for help from our community to lead the space towards a better, more inclusive future.
  • Promotion: we’re doing our best but:
    • Our Facebook group and page are run by someone who is ambivalent about the medium.
    • We could use someone who is prepared to put more time into our MeetUp group.
    • We need people to write blog posts about what we’re up to and organise our presence at events such as Maker Faire UK and MakeFest Manchester.
    • We need people who are happy to find groups and communities both online and off, and spread the word about the fantastic world of hackspaces, and ours in particular.
  • Infrastructure: some of our areas have groups of people who have taken responsibility for them. The areas are as follows:
    • CNC: this is pretty well covered but if you’re particularly interested in joining the maintenance teams speak to Tas (NotQuiteHere)
    • Craft Corner: needs more people, talk to Chris (Badspyro). If you’re interested in anything from paper craft through to model painting, via our glorious sewing machines, or even something entirely off our radar that you think would make a great addition, please give us a shout. There are plans afoot for screen printing (Ruth is particularly interested and will point you in the right direction) as well as a myriad of other notions and hobbies too numerous to mention!
    • Metalwork desperately needs more people, talk to Greg (GregMorris)
    • Woodwork ditto, talk to Bob (thinkl33t)
  • Documentation, Health & Safety: much of the equipment we have in the hackspace is potentially new to a lot of members. A key function of a hackspace is knowledge sharing, including how not to injure yourself, how to use it to the best of its ability, and how to take care of the equipment (such as noticing when something is wrong with it). We need more people involved in the effort to make as much knowledge available as possible, and welcome involvement from anyone who wants to help. Speak to Chris (Badspyro) if you think documentation is awesome.
  • Snackspace: the list is available on the wiki. If we’re running low on stuff feel free to top us up. Shout for a Bookers/Makro card ( telegram is the best place to find us ) and knock yourself out. Don’t spend more than £200. Email the receipt to for reimbursement.  Get a VAT receipt!  We’re not VAT registered but if we ever do, we can claim 5 year’s worth of VAT paid!
  • Volunteer: we always need people to help run stalls at events and generally talk about our hackspace and the projects that people do there. So, if you’re a people person and are happy to turn up and chat about what you do at the hackspace (Arduino, Raspberry Pi, electronics, laser cutting, 3D printing, crafts, whatever) and/or assist with a more structured  workshop such as Build A BUG! please let us know. We announce events via but can’t run them without people to assist.
  • Organise an event: got something you want to do? Organise it! Events can be run in the space providing you don’t prevent other members from using it and there is at least one member present at all times. If you want to run something that would stop members using the space that is also fine providing it’s announced via the mailing list ( ) in plenty of time and no one seriously objects.
  • Hack-the-space days! – Organise one of these! Hack-the-space days are our chance to house keep and maintain the space infrastructure from regular equipment maintenance to building the physical space and everything in between.
  • Run a workshop, start meet up, introduce a regular open night activity. Want examples? 3DPUG (Bob/Thinkl33t), Locksport (originally I have no idea now Tas/NotQuiteHere and Greg), DandD (Kat/BinaryKitten), Sanctuary Games (Kat/BinaryKitten), Manchester Space Programme (externally organised and changed venue when we moved).

I don’t have enough time/experience/spoons to help with the big stuff what can I do?

10 minutes of tidying

The biggest thing that every member can do for the space is spend 10 minutes each time they come in tidying or cleaning the space. Particularly the tables, workspaces, and walkways. Walk around, pick up any dirty cups people have missed, throw away rubbish, put things back where they belong, wipe down the tables, brush the floor, empty the bins and take the bags down to the skips. If everyone spends just 10 minutes making our space better each time they come in it will make a huge difference.

Simple English Version

Dear Members,

We need help to make the hackspace work well for everybody.

Hacman is a community organisation. That means all the members are equal partners. We have a board. This is 5 people who do some admin jobs for Hacman. The board makes sure the bills get paid on time. The board makes sure that new members learn how to use the hackspace. The board deals with any complaints from members.

All members need to help create a good working hackspace. Our new hackspace still needs a lot of work so that everyone can use it. At the moment we need more people to do some of this work.

Here is a list of things that we need members to help with:

  • Accessibility. This means that we need people to say what they need to be able to use the space. We also need people who can explain what changes other people might need to be able to use the space. This could be changes for people in wheelchairs, people with seeing or hearing problems, people with assistance dogs or people with other disabilities that are not obvious. We want to make the space a good place that everyone can use.
  • Promotion. We need people who like using social media like Facebook and MeetUp to do Hacman posts. We need people to write blog posts about Hacman events. We need people to run Hacman stands at makerfaire and other events. We would like members to find places to talk about hackspaces and Hacman so that more people find out us.
  • Infrastructure. This means the physical areas in the new hackspace. If you can help make these areas ready to use, please help.
    • CNC – if you want to help with this, please talk to Tas (NotQuiteHere)
    • Craft Corner – physical crafts like paper modelling, sewing, screen printing. Please talk to Chris (Badspyro).
    • Metalwork – Please talk to Greg (GregMorris)
    • Woodwork – Please talk to Bob (thinkl33t)
  • Documentation, Health & Safety. We have a lot of tools and equipment. We need help with training new members, and writing signs and instructions. Some of the tools and equipment can be dangerous. New members need to learn how to stay safe and have fun in the hackspace. We all need to know how to look after the tools and equipment properly. This will keep the tools and equipment in good condition. Please ask Chris (Badspyro) if you can help with this.
  • Snackspace: This is the food and drinks that we sell to members at Hacman. The list of items is available on the wiki. Any member can ask for a wholesale      shop card (Bookers or Makro) and buy more food/drinks when there is not      much left. Please ask on the hacman Telegram channel for a card. Please do      not spend more than £200. You will need to email the receipt to to get paid back      the money you spent in the shop. Please get a VAT receipt when you shop.
  • Volunteer: we always need people to help run stalls at events. We need people who are happy to talk about what they do at the hackspace. We also need people who can do demonstrations at events e.g. building a mini robot. We tell members about events on the Hacman Telegram channel.
  • Organise an event: Any member can run an event in the hackspace. Events must have at least one Hacman member present. If the event means that other members cannot use the hackspace at the same time, then other members must agree that this is okay.
  • “Hack the space” days. We want people to organise one-off days where members work together to improve the hackspace. This could be painting the walls, or building a bench, or organising storage, or making the hackspace easier for everyone to use.
  • Run a workshop. We would love people to offer a one-off or regular session that is open to the public, as well as members. You can share a skill or interest with other people. You can ask other members for information about past workshops to get ideas.

Lastly, all members can help every time they are in the space. Please spend a few minutes tidying up. You can clear the tables and benches. You can sweep the floor or empty the bins. It is very important that we keep the space clean and tidy for everyone to use. Please also make sure that nothing is left where people could trip over it, or it gets in the way. This will make the hackspace a safer and more fun place for all of us to use.

Dryhootch Fence Removal

This month a team from the our makerspace volunteered to remove some fencing for Dryhootch coffee shop.  Dryhootch is a coffee shop that provides a way for veterans to reconnect.  The front patio of the shop was enclosed with 6 foot steel bars, which does not make it look inviting.  The organization came by the space to ask for some help and said we could take the fence with us.

Dryhootch 2 images IMG_2462

We call that a “WIN, WIN” scenario.  We got to help a good cause and got a bunch of raw material for making things with.  I’m sure you can look forward to more projects with Dryhootch.  Now that we have a pile of steel its time to get making.


Special thanks to Tom G., Wolfgang, Shane, Vishal, and Mark for volunteering a Sunday morning to help.

Happy Birthday Linux! (kind of)

Speaking of internet lore, Linux is 25 years old today!


(yeah, it’s a wedding cake, sorry – but all of the photos of cakes featuring Tux on Flickr are “all rights reserved” – what the heck is up with that?)

25 years ago today, Linus Torvalds announced he was working on a free MINIX-like OS:

I’m doing a (free) operating system (just a hobby, won’t be big and
professional like gnu) for 386(486) AT clones.  This has been brewing
since april, and is starting to get ready.

The kernel wasn’t released until September, but the August 25th announcement is considered the birth of Linux.

Linux runs some 96% of the servers on the internet – not bad for a hobby!

On the 4th Wednesday of each month (6-9pm), Kwartzlab has a 3D printer meetup, for everyone who is interested in 3D printing, or for those who would like to learn more about it. Each month, we try to invite guest speakers or arrange technical demos.

Tomorrow (Wednesday August 24), Pablo Eder from Lani Labs will be visiting. They make tools that make it easy to share, control and automate 3D printers over the internet.

In addition, Kwartzlab member Chris Gibson will be demoing his “RoVa4D” Full Color Blender 3D Printer, which is now working and making prints. The kickstarter for this printer ends Wednesday morning at 10am. Check it out:

Happy Internaut Day!

Hey, Internet (or is it just “internet” now?) you’re 25 years old? You don’t look a day over 24!

The internet was supposedly opened to the public on August 23, 1991. The problem with this date doesn’t seem to have any relevance in the history of the internet or the web. Who doesn’t love a little contrarian history? Go read a debunking by Fortune:

The building blocks (the HTML language, URI web addresses, and the HTTP protocol) were specified and written up by October 1990. The first webpage went live in December of that year. To quote the Web Foundation’s Berners-Lee-approved history: “By the end of 1990, the first web page was served on the open internet.”

So technically, the world-wide web has been on the internet for more than a quarter century. Only they didn’t tell anyone about it until a news group post on August 6, 1991. And of course, the first graphical web browser program, Mosaic, wasn’t released until 1993.

So happy roughly 24-26th birthday, internet!

Mayor’s Summer Works at LVL1

Over the summer, member Divinity Rose coached a team of Junior Achievers as they worked to develop their technology based product and startup “Sensor Buddies.”  The team was being paid as part of the Mayor’s Summer Works program that employed 4200 youth over the summer. The team of three 17-year-old students from Central High School […]

Power Wheels Racing

Race HeadLast month the Milwaukee Makerspace power wheels team packed up the cars and road tripped to2 images vertical Maker Faire Detroit.  After long nights working at the space until 4am for the week before the drive Ed, Kathy, Pete, Andy, Vishal, and too many others to mention got 3 cars race ready.  The Bluth Stair Car, Super Tux Kart, and Hippie Rose made the journey to Detroit without damage are and were a blast to drive.


Our 3 cars raced with 34 others in the biggest Power Racing Series event to date on the biggest track ever made.  It was great to see all the hard work paying off as the builders of the cars became the happy drivers of the cars. Both days of races were streamed live by our friends at Make Magazine to where they can still be watched. Be sure to check out the race at Maker Faire Milwaukee September 24th-25th.


Check out the race from day one at the link below:

Time To Get Nerdy!

Nerdy Head

Make sure not to miss this weekend’s Nerdy Derby at American Science and Surplus. Adrian and the rest of the nerdy team will be helping kids and kids at heart turn blocks of wood into rolling masterpieces of speed. If you have not been to a Nerdy Derby event this will be one not to miss.  3D printed wheels have been coming in from printers all over the city and from our Makerspace 80 at a time.

2 images nerdy

Building a car is easy and there will be a nice long track to race down once you’ve finished your creation.  You start by picking a block of wood and some wheels. After a bit of nailing its off to nerdy up your car from piles of amazing decorations. Makers are encouraged to decorate, test, and re-decorate. Everything that you glue onto a car affects the way it moves down the track. See you there!

3D Printing fest, metal work, freebies and other goodness

It’s been a while since we’ve posted an update, so this is going to be a long one!



Membership levels are climbing steadily, now at 25 – just short of the our sustainable target.  Wednesday’s have also been getting busier, to the extent we’ve had to extend the table area and buy a bunch more chairs.

As we settle into the space, we’ve (the directors) felt the need to gather some feedback on how everyones feeling – so we’ve just issued a member satisfaction survey.  We’ll review the outputs at the September General Meeting.


3D Printing 

Even as 3D printing goes mainstream, most people still haven’t seen/touched/experienced it in person, so it remains a hot topic for us to talk about.   In the last 6 wks, we’ve organised:

  • Two 3D printing workshops at the space
  • A 3D printing workshop at Oakhurst Primary school, along with a printed roller coaster kit (thanks to Rob/Jess)
  • A 3D printing intro the for new Swindon Drone Club

3d printing at oakhurst

We received some great feedback from these sessions (and a little revenue), and will no doubt continue organising/running them whilst we have time/energy – volunteers for running future workshops wanted!

Steve has also been busy upgrading the donated Wanhao i3 with a new extruder (and replacement thermistor).  At this point, both printers are usable, albeit the Wanhao still needs a firmware tweak to correct thermistor readings (it’s measuring about 50 deg below actual).  Also had some more filament donated, adding to the already large selection.


Metal work

Our welding setup is now ready to rock.  The welder itself is on loan from Steve, plus we’ve now acquired safety gear (welding mask, gloves) and a large 8’x8′ welding screen (stored on the roof of 34a).  It’s a dangerous piece of kit, so anyone wanting to use it needs to be inducted via Steve, or one of the other members with welding experience.

We also received a Proxxon MF70 CNC mill last week (long term loan), which came with tool bits, clamps, indexing head, etc.  Runs on a GRBL-based Arduino+driver board, but needs a host computer to generate/feed G-Code.  There’s a few bits of final setup to go (wiring, toolchain), but very close to usable.

The Shapeoko 1 is still progressing through it’s dual Y-belt upgrade, next step is to fit the drive pulleys and new belts.  Then it’ll be onto limit switches and a firmware update.


Influx of Freebies (Junk?!)

We got a bit carried away with a unit clearance down the corridor, taking a huge influx of “stuff”, caused a fair bit of disruption for a week and has left us with a lot of probably junk.  A cautionary tale for handling future freebies, and one we’ll loop back on at the Gen Mtg.

influx of junk

Nonetheless, there is now a LOT of timber and metal available for member projects, most of which has been tidied up onto the roof of 34a.

tidy roof space

There’s also a whole bunch of random items if anyone can make use of them:

  • Collection of fire extinguishers
  • Large gas bottle
  • Petrol strimmer motor
  • AC motor from a submersible pump

… and probably some other stuff I’ve forgotten.  This also provokes the need to improve our process for getting rid of unwanted items  – another thing we’ll review at the Gen Mtg.


General Bits

Aside from the more obvious changes, there’s also been a whole bunch of other things going on, to mention just a few:

  • Donation of a Binocular Watson Barnet Microscope from John
  • Rob upgraded the RPI running the internal CCTV
  • We’ve got permission to use the Twigs Kiln if anyone wants something fired
  • The sewing machine is confirmed working and getting some use on Textile Tuesdays
  • Josh donated a spray booth, Jess & James a compressor and Damian an airbrush – so we now have a full airbrush setup for modelwork, etc
  • Josh completed a proper PCB for the door controller (which now needs to be tested/installed) and Damian upgraded the door controller firmware to lock on close
  • We’re trying to organise water into the space from next door
  • A quote for ventilation via the glazing is in progress



Coming Up

We have a couple of activities/workshops coming up (see events calendar for more info), including:

  • Arduino surgery – Sat 13th Aug
  • Toy Blaster workshops with a local youth group and the 1st Swindon Cubs

Along with a whole bunch of improvement tasks to work through on Trello, including a couple I’m very keen to see progressed:

  • Finish getting ShapeOko and Proxxon working
  • Test radio setups and wifi link on the roof


Look forward to seeing you at the space  🙂

3D Printed Origami

The Digital Dentist, Mark, is printing up a storm as usual.  When he’s not printing wheels for upcoming Nerdy Derby races he’s working on something unique.  This week Mark is working on 3D printed origami.  Triangular forms are printed flat and then folded into geodesic spheres.

3d 3 images

These shapes are destined to be lights.  Each of the ping pong balls will have a light in it.  Be sure to watch for the final product at Maker Faire Milwaukee.
