Milwaukee Makerspace

88nine Lazzored!

Radio Milwaukee Lazzored!

I used the laser cutter to make a Raspberry Pi case, and rather than leave the front of it all boring, I added an 88nine Radio Milwaukee logo to it. (Since I had a project that involves a Raspberry Pi and 88nine, it seemed appropriate.)

Radio Milwaukee Logo

I started with the original 88nine logo, which is brown and orange. I couldn’t find a nice hires version, but a quick web search turned up something that would work…

Radio Milwaukee Logo

To start with, I converted the logo to black and white, since color wasn’t going to matter to the laser cutter…

Radio Milwaukee Logo

I then separated the top bars (which are orange in the original logo) and dithered them to create a visual separation from the bottom part of the logo that was brown in the original.

Radio Milwaukee Logo

Here’s a close-up of the dithering pattern. It’s extremely simple, but it worked. I’ve done a lot of work with halftones and dithering, and you can get extremely complex, but sometimes the simple things just work.

Radio Milwaukee close-up

Here’s a close-up of the final piece of Baltic Birch plywood with the logo etched in it. I’m pretty happy with how it turned out.

Time Lapse Bot on Watch

Time Lapse Bot

With Milwaukee Makerspace still in a state of constant change, I thought that Time Lapse Bot might enjoy keeping an eye on things…

Time Lapse Bot consists of an old laptop running (an older version of) EvoCam to capture an image every X number of minutes or seconds.

Time Lapse Box

The whole thing fits in a nice box that you can easily carry around and place on a table or other flat surface to capture images. You’ve probably seen Time Lapse Bot at various BarCamp events around Milwaukee.

Time Lapse Bot + Base

Eventually carrying Time Lapse Bot around looking for something to set it on got tiresome, so I built a rolling base from an old office chair. We also upgraded the camera over time, starting originally with an old VHS camera with a USB adapter, then moving up to a MiniDV camera with FireWire, and now a Logitech C910 Webcam, which captures HD quality images. (We also recently added a gooseneck for easier camera positioning, and a bit of height, as you can see in the top photo.)

There’s a heap more info about Time Lapse Bot over on my web site… and if you remember the Red Lotus build from last summer, or the Grand Opening at Chase, yeah, those were done with Time Lapse Bot.

Syn2Cat

Game evening

So hackers are computer nerds? Think again. We like to socialize, do creative things and build stuff. So what about games? Computer games do not always give that social aspect as with the classic board and card games.

So some fellow syn2catters met last Thursday for a game night.

The chosen game was Munchkin. An monster role playing game pressed into a card deck.

After  explaining  some rules we got into play and learned the rest on the way. Interestingly, the newcomers to this game all became elves, and one won the game even though some more experienced players were there.

 

This experience need a repetition so who’s in next time?

TOG

Engineers Week: Night of Ideas

EngineersWeekLogoTOG will host a night of inspiring talks. Each speaker will only have 15 minutes to convey to you their passion and enthusiasm on a given subject, idea or project. With six talks on the night you will be introduced to a diverse range of subjects.

Date: Thursday 28th February

Time: Doors from 18.30, Talks 19.15

Location: TOG

Cost: Free

Talks

Title: Technology and Inequality

 

Description: How advances in science and engineering may leave us with a much less equal society.

Speaker: John Looney

 

Title: “You Spin Me Right Round” - The Future of Biomedical Diagnostics

 

Description: Our research is focussed on developing a particular type of “lab on a chip” device; namely 
centrifugal microfluidic devices. Microfluidics is the science and technology of fluid flows
on a miniature scale. Centrifugal microfluidic platforms differ in that they use the centrifugal
force, akin to the force experienced by someone when driving around a roundabout, to move
the sample liquid through a disk. The disk is typically the size of a CD/DVD and composed
of a cheap plastic material. This new area of microfluidics research has emerged as a highly
useful tool for disease detection, with many of the necessary steps in fluid analysis being
miniaturised and incorporated onto these lab-on-a-disc devices.

SpeakerJennifer Gaughran and Mary O’Sullivan

 

Title: A Bridge Too Far or Very Close ?

 

Description: Bridge building competitions are they just a bit of fun or the greatest STEM education tool ever. The talk will serve as a review of our competition.

Speaker: Jeffrey Roe

NYC Resistor

Our First Make-Along: Felting!

Felting Needles

felting needles


Resistor had it’s first crafting Make-Along recently. Our theme: Felting. We started with wool roving, which is wool that has been carded or combed in preparation for being spun. It looks a bit like cotton candy. Roving can be felted by agitating it, causing the individual fibers to knot together. One way to do this is to poke a bundle of roving repeatedly with a felting needle, which has tiny grooves that catch and pull at the fibers to tangle them. This is particularly effective for delicate work, and is a nice tool for creating small balls and creatures and for doing applique.

felted creatures

felted balls and creature

Another way to felt is to wet and rub the fibers. We made some felted soaps this way. We started with glycerin soap, wet it and wrapped roving around it, and then moistened it again with hot water to press the fibers onto the soap. After this the soap was dropped into a plastic bag and rubbed until frothy and matted. Then we rinsed them, and left them to dry. The result is a decorative, scrubby soap. Designs are created by felting onto the roving before wrapping it around the soap. Surprisingly the wetting and rubbing procedure doesn’t distort the design.

felted soap

Felting can also be a creative way to repair clothes. One of our felters at the Make-Along brought a sweater with a hole in it, and felted on a flower on as a patch.

At our next Make-Along we’ll be working with paper. We’ll have patterns, ideas, and some supplies, but you can also bring your own projects and supplies. Here’s a little inspiration.

Nottingham Hackspace will be hosting an all-day Introduction to Arduino Workshop, run by James Fowkes and Ian Dickinson, on Saturday, 9th March.

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, and will cost £10, which includes use of all tools, boards and components, and free tea or coffee.

Arduino boards and kits will also be on sale for further exploration of this fantastic system.

To sign up to this workshop, please visit the EventBrite page.

ANTS! TREMBLE BEFORE YOUR NEW OVERLORDS!

Ants’ new home gets blinged up. They can thank us later…

Jordan, Pete and I managed to finish the ant farm!  It is now home to over 1000 red harvester ants.  Unlike old ant farms that use dirt or sand,  ours uses a gel that was originally developed by NASA for ant experiments in space.  We are still looking into ways to make the gel ourselves, but in the mean time we found a website that manufactures the stuff, antgel.com.   The gel contains all the food and water that the ants will need to survive.  It even helps prevent them from developing infections.  The ants should have everything they need to reach the end of their life cycle, which should be in about 6 months.  

Right now, all the ants in our farm are workers, we don’t have a queen yet.  We have been discussing ways in which we could obtain a queen.  But it will probably be awhile before we decided to go through with it, since we would have to take extra precautions to ensure that a queen wouldn’t escape.

We are trying to get a camera up and running so we can make some time lapse videos of the ants as they work.  In the meantime, stop by open house and check them out for yourself!

 

The ants are settling in and have begun making tunnels.

 

 

Our original plans. The actual farm size is 16.0″x26.9″x2.25″. We went with box dimensions that were in proportion to the golden ratio for ascetics.

GaelHack 2013

GH_Logo_Black
Some of you already know that members of the Irish Hackerspaces Community have been talking about running a Hacker / Maker Camp in Ireland, similar to other events like this such as EMF Camp last year in the UK.

GaelHack is to do just that! From 7th – 9th June 2013 hackers, geeks, scientists, engineers, artists, and crafters will meet in Mount Melleray Scout Center, near Cappoquin in Waterford. There they will hold workshops, talks, and be able to collaborate on projects to their hearts content, and hopefully well past their bed time.

At the moment early-bird tickets are just €80 and that includes camping/dorm accommodation, and basic food. What more would you want from a weekend? Well you can tell us, and join the mailing list to help in making GaelHack a great weekend.

Spread the good work on what we are trying to do. Website for the event is http://gaelhack.hackerspaces.ie

Clint Rinehart
Topic: 3D Scanning with Open Source Software and Microsoft Kinect
Time/Length: 30 mins 1215-1245 (UTC−05:00)

3D scanning is a common practice among 3D printing enthusiasts.  This technology is no longer a limited modality with research or corporate funding, but now a practically attainable practice with a VERY low cost of entry.  This talk will feature the use of a Microsoft Kinect device with ReconstructME software.

Chris Caswell - [carrythewhat?]
Topic: Replications: a case study on the basic economics of Distributed Manufacturing of Free & Open Source Hardware. 
Time/Length: 15 mins 1245-1300 (UTC−05:00)

For 18 months now, our desktop 3D printers have been producing commodity prints and sold on the market. With 3 printers now, we are approaching viability as a self-sustaining business. But we have shown there is this small repertoire of digital goods, capable of desktop replication, and valued by the market -- set only to expand as replication technology advances and the software catches up.  Along with our experiences so far, I will share my thinking on free & open source hardware, distributed manufacturing, and an open economy.

Emmett Lalish - Engineer or an Artist?
Topic:  Designing 3D-printed mechanisms
Time/Length: 30 mins 1330-1400 (UTC−05:00)

I'll give some pointers on using OpenSCAD to design complex, printable mechanisms. I avoid using support at all cost and in my book, the order of coolness for mechanisms goes: bolt together, snap together, preassembled. The beauty of 3D printers is that they make preassembled mechanisms possible for the first time, but designing them requires thinking about shapes in a whole new way.

Raspberry Pi Flavored Pd Patching Circle Sunday 2013-02-10

PdPi_cropOn Sunday February 10th, starting at noon, we’re going to have a Pure Data patching circle, with particular interest in using Pd on the Raspberry Pi.

A Patching Circle is an informal gathering of anyone who is interested in patching languages (Pure Data, Max/MSP/Jitter, etc.). Beginners and experienced patchers welcome. Open to everyone – work on personal or professional projects, school work, or just patch quietly to yourself, in a room full of other people patching patches and helping other people patch.

This time, we will have some special guests, including Miller Puckette, creator of Pure Data, and UK Composer Julian Brooks, who will be demonstrating some of his work in Pd.

If you have any Pd or Raspberry Pi projects to show off, please contact Theron at theron.trowbridge@gmail.com.

The event is free.  There is an Eventbrite page set up for RSVPs: http://www.eventbrite.com/event/5026873514  – just so we know how many people are coming.

We will have copies of the Miller MUS 171 class available to copy (bring a USB stick or hard drive with at least 16 GB of space), as well as the Pd-Pi image to use Pure Data on the Raspberry Pi.

Somehow I never managed to connect with the man behind BrownDogGadgets until recently when we somehow became friends on Facebook, and I then realized that Joshua was the driving force behind BrownDogGadgets.

BrownDogGadgets makes a variety of fun electronics kits, many of which center around solar energy, and many of which fit in empty Altoid tins. (There’s also some Arduino-compatible kits which look pretty interesting.)

We’re glad to have Joshua as a new member of Milwaukee Makerspace and look forward to having someone with kit-making skills in the group.

Check out browndoggadgets.com for some awesome kit fun!

Syn2Cat

Quadrocopter factory

This Sunday we got serious about putting it all together: building our own mini quadcopters.

Kenn gave some insights into the mathematics behind keeping an unstable system dynamically at rest. Same thing as balancing a broom on a fingertip, just that your head does not need to do a mathematical development over 27 pages to do the inverse of the 4D matrix.

No we didn’t do that either. So it was: the transform matrix is A, and to get our values, we need A-1.
Math is cool, it proves stuff that you say is intuitively correct. Like that you need at least 4 propellers, that 2 have to run in reverse, and that those need to be on opposite sides of the same arm. Else A-1 does not exist and your copter is impossible to fly. It’s like the division by zero in matrix. Did Neo do that in the movies?

The build was quite easy as we got several 3D printed parts in the kits Kenn provided.

These parts were printed on a refrigerator-sized 3D printer in an American university, but Guilluame thinks the Ultimaker can build the same parts.

The concept is built around the idea that weight is the biggest enemy to flight. The heavier the UAV, the more energy involved in a crash, and the higher the likelihood of breaking things. So the UAV always needs to be light as possible. Here, the arms are made of carbon fiber kite tubes, held together at a center brace. The brace does not need to be very strong, since the quadcopter only weighs ~150g, which means each arm is lifting ~38g. That’s about the weight of a chunk of baguette bread. Compare that to the tensile strength of the carbon fiber and see that the model is far stronger than it needs to be.

The middle plate is FRP, which rigidly links the carbon fiber tubes together, at the same time as providing stiffness and a handy platform for mounting equipment.

Build a cross, put the base plate on.

Strap motors on and solder the power ends together. Putting the motors on is easy: just some double-sided tape and zip ties. Remember, the goal here is to be crashable, so extra emphasis is paid to having easy to repair assemblies!

While putting motors on is easy, soldering the wiring harness never is. 4 motors have to connect to one battery, which has led to countless variation on the internet, but never one approach to rule them all. At the syn2cat, each hacker went his own way, making a wiring harness to fit the custom direction they’re going with their quads.

Place the battery. Nicolas Petit has a nice paper describing the advantages of placing the center of gravity higher instead of lower.

We use the STM32F3Discovery board, second from left. It’s big, but it’s an awesome value. For $10, each hacker gets a 3-axis magnetometer, 3-axis gyroscope, 3-axis accelerometer, and ARM Cortex M4 processor, with an integrated hardware debugger to boot. Hackers who want to upgrade to one of the smaller boards in the picture will be able to micronize, but at a cost of ~$100.

There is no mount, so it’s Styrofoam and rubber bands. This makes it easy to repair and rebuild.

Kenn also came up with a nice idea to raise funds for syn2cat. Auctioning off bling bling stuff for the copters. There were LED strips, light fibres, better chargers, and an OSD display for putting your telemetry on a video stream.

We got a nice overview of the software by Vinz Kessler, one of Kenn’s fellow developers from Tau Labs. How to get the software, compile and start. And how to connect the controller board.

Now it only needs to get connected to the receiver, and mount propellers.


Then it should fly, if the software is OK. So flashing the autopilot onto the device.

At the end of the night, we had two quadcopters almost ready to fly. Ten more left to finish.

The first flight tests will be this week, and within a couple weeks everyone should have theirs flying. Keep watching this space for upcoming video of 12 sub-$200 quadcopters in flight.

NYC Resistor

Robot a Month for January: The Soft-Boiled Eggbot

As midnight approached this New Year’s Eve– as champagne bubbled from uncorked necks and we all prepared for the coming year in various postures of revelry or bleak resignation– I grappled silently with the pivotal question of our time: “How awesome are robots?” The answer is of course that robots are completely awesome. That settled, I resolved to build one robot a month for the duration of 2013.

Much to the chagrin of Brooklyn’s legion of artisanal slow-cooking egg-boilers, January’s robot is a an automaton for preparing soft-boiled eggs for human consumption.

This was a junkbot, assembled from various scraps that have ended up in the space over the years. Expert junkspotters will note:

  • The heating element and thermistor from a trashed mini-espresso machine
  • One 250mL beaker of questionable provenance
  • Some off-brand extruded aluminum
  • Skate bearings
  • A haunted steel counterweight
  • Lots of lasercut acrylic and delrin
  • Some chunks of 4×4 sliced out of the loft supports from the original NYCR location
  • A couple of analog servos and a DC motor from the junk drawer
  • One half of a L298 from a driver board I designed in 2005
  • Some relays from sharesville
  • A button from a reflow oven
  • Random bolts, plywood, etc.

The whole shebang was controlled by a Teensy 2.0 and powered from a bench supply (except the heating element which was run off of 120VAC, which is why the lights keep dimming during the video).

All the code and CAD files are in my Github repo, as usual. Special thanks to Charles Pax for donating the boiler from his busted coffeemaker, Eric Skiff for providing the tunes for the video, Nick Farr for a last-minute game-changing special Club Mate delivery, and everyone at NYCR for indulging my little robot habit.

UAV workshop

Our American member Kenn has spent the last months fascinating everyone with his projects on unmanned autonomous vehicles, be they quadcopters or airplanes. So his offer to run a workshop on building your own little quadcopter was extremely well recieved. 12 hackers jumped at the chance and after a few trials and travails, hardware for 12 complete UAVs was finally delivered.

material to build 12 quadrocopters

Last week Sunday, we started hacking our remote controls. They needed to be changed from Mode 1 to Mode 2, flashed to the open-source Open9x firmware, and configured.

This Sunday, it was the tiny little brushless motor controllers turn to be hacked, flashing them with BLHeli in order to make them fit for the needed fast reactions. The flashed firmware can make the ESCs respond an order of a magnitude faster to input commands.

Precision is the word of the day, as good connections with tiny programming pads have to be made, over and over again. To make things even harder, the pads are hidden under heat shrink plastic. This has to be done a total of 60 times, as all the controllers needed  to be flashed (4 for each quadcopter, plus some spares).

Poking at the pads with tiny sewing needles while the board is being flashed is a tricky job. Too little pressure and the connection won’t be good. Too much pressure and the needles can damage the pad. Gunstick came up with a simple contraption built out of legos.

Note that you need those little LEGO guys to supervise correct placement :-)

Every hackerspace needs it’s box of LEGOs.

Below you see how needles are correctly placed and held in firmly by the levers.

This allowed for quick flashing and swapping of the boards. And of course the ubiquitous arduino was there to do the job.

After flashing, the controllers are soldered onto the motors. Half of them upside-down as we need half of them to run in reverse. We’re crossing our fingers on that one.


Never forget to tin the wire leads first. The connections need to be solid.

Meanwhile more flashing is going on.

Yes, it’s using windows. Ye gads!

Water, Water…

Water!

We had to pause a bit last night when we saw some water in the space… Our old location at Chase was well known for the leaky roof and the occasional floods. It turns out the water was just from the electrician’s truck that was pulled into the space. Whew!

The Lenox building has been water-tight so far (knock on MDF!) and we’re feeling secure in the fact that everything that should stay dry will stay dry.

Kevin also demanded I take an “arty” photo of the water. Enjoy!

Hive76

Hydroponics Update

Spinach about a week after nutrients added.

 The spinach I was growing managed to complete most of its life cycle. Around a week after my last post I added the nutrient solution to the plants’ water, thats when they really started to take off.  I had one hiccup during the test run where I didn’t properly sent the flow rate of one the IV bags and half the nutrient solution was lost. If I was a little less… well lazy that day… I would have replaced it , but I didn’t.  So the IV bag ran out of nutrient solution and some of the plants died before they reached maturity.  Luckily, the rest of the plants managed to reach their flowering stage.  So overall, the IV bags were incredible useful. Thanks Jordan for the idea!

 Seeing how classes are starting to pick up, I figure now is a good time to stop the experiment and take some time to look over my notes.  But, I hope to have another prototype built by the end of next month. ( Btw, sorry for not being around open house lately to discuss hydroponics, I have a night class that meets at the same time this semester).

Speaking of which, a friend of mine who frequently stops by open house, Ian, has taken the plans of the hydroponic garden I built two years ago and built one of his own at home.  Suffice to say, the plants have grown wild and are firmly in control of his bedroom. Given how successful his garden has been, he’s inspired me to dust of my old plans and think about building another, LARGER, set up for just for show (the hydro setup currently at Hive is mainly for experimentation).  That’s all for now…

Spinach reaching maturity.

TOG

One Small Step: Open-Source Night

Starting in February, Tog will be hosting a monthly open-source evening on the 3rd Wednesday of the month. These hands-on sessions aim to bring together experienced open-source contributors with people who would like to get started but aren’t sure where to start or would generally benefit from having someone to ask questions to. All types of contributions welcome: documentation, code, testing, graphics, translations…

We have confirmed participants with varied levels of experience in Gnome, OpenStack, Django. If you’re an experienced contributor interested in attending, feel free to drop me an email at julie (at) tog.ie and I’ll add your project(s) to the list. If you’re an aspiring contributor interested in attending, you can drop me a note too with the projects you’re planning on looking at during the evening.

If the project you’re interested in isn’t mentioned, please come anyway. We can figure out how a project works together. Likewise, people are welcome to come and work on their usual open-source stuff – just be open to the occasional question :) The more people, the merrier!

The first event will be held on Wednesday, February 20th, with Tog opening at 6:30pm and the first talk starting at 7pm.

Every month we will start with a couple of people speaking for 5-10 minutes, to introduce the project they are working on, what is the usual path for contributing and where they are currently looking for help. Then we will form groups and work on making a contribution for the rest of the evening.

Leathercraft Workshop on Saturday, 23 February

Slim Leather Wallet

Learn how to make a leather wallet, gadget case, key fob or mouse mat in this informative all-day workshop run by Jake Howe on Saturday, 23 February.

Leather is an effective and strong material to work with, ideal for long-lasting and thoughtful gifts.

At the workshop, you can make:

  • Slim Leather Wallet
    With a design that uses only a single piece, this slim wallet has a notes pocket, room for around 8 cards, and the option for priority cards.
  • Leather Gadget Case
    A nicely formed case designed to fit your phone or similar-sized object perfectly. Involves making a wooden “dummy” version, then fitting wet leather around that dummy.
  • Leather Key Fob
    A small and personalised key chain made by fitting wet leather around a small piece of wood or hardboard.
  • Leather Mouse Mat
    Leather gets smoother the more you use it, making it an ideal surface for a mouse mat, and it’s made by fitting wet leather around hardboard for a one-of-a-kind mouse mat.

And if you don’t want to make something with leather, there is also the option for an oil cloth wallet, using brightly patterned waterproof oil cloth to create a unique and attractive slim wallet.

The workshop will run from 11am to 4pm, and will cost £10, which includes leather or oil cloth and a pinpoint punch awl, ideal for working with leather or thick cloth. The workshop will also have free tea or coffee and a tour of the Nottingham Hackspace.

Register for the workshop now!

A Clockwork…Room Divider

A 6 foot tall, clockwork gear inpired, tri-fold room divider

Hopefully, we can use this as a backdrop for events like the Art Jamboree.

I’ve been toying with the idea of room dividers for a while now. I don’t exactly have use for one, but I think they look neat and it’s basically a blank canvas. Drawing inspiration from my Clockwork Boxes, I decided that a gear motif would best suit the makerspace, thus giving me a new use for the piece: as a backdrop at events we participate in such as Art Jamboree and the various Maker Faires.

A picture of myself, Jason, and Matt, standing around the room divider

There are 3 of us in this photo. Really.

The actual screens were cut out with a large-scale CNC router, while the frame was ripped from 2×4′s, with a dado groove down the center for the screen to slip into. Thanks, Jason H.!!

Assembly went well, although there were a few hiccups.  The drill bit wasn’t long enough, so some minor splitting occurred at a couple of spots. The frame was slightly warped and so needed to be clamped and glued before being screwed together.

After allowing the paint to dry overnight, myself, Matt W., and Jason H. assembled this thing just prior to heading to the Art Jamboree at the Hilton in Milwaukee.

EDIT: I’ve just entered this into the Furniture Contest that Instructables is running. Click the link. Vote. Be thanked. :)

LEGOlamp

LEGO_lamp_2_complete_dark   This is the assembled LEGOlamp.  It will be mounted as a ceiling fixture, with an internal bulb.  To light it for this picture, I used a desklamp to project light into the tube.

One idea I tried after the previous post, was slicing the tube into 16 rings.  The idea was to glue the bricks to the tube, with the bricks stacked vertically, then offset the rings after the bricks were attached.  That approach failed.  I was unable to cut the rings smoothly, resulting in large gaps between them.  When stacked, they looked horrible.

In the end, a simple change of adhesive and application made the difference.  First, I abandoned both hot glue and epoxy.  I discovered gel super glue has sufficient open time to position the bricks, but also sets quickly enough that clamping and supporting the bricks was unnecessary.  I addition, I realized the important joint is between the bricks.  If the bricks are firmly cemented to each other, the connection to the tube can be a series of comparatively weak joins.  Less glue on the end-face means less glue to smear, and less chance of accidentally gluing the template in place.

 

drillpress_dremel_saw  Many people have asked how I cut the LEGO bricks.  Initially, I used a sharp chisel.  That was tedious, as each brick had to be clamped.  After that, I switched to a rotary-tool held in a fixture, with a standard abrasive cut-off disk.  That worked well enough.  Finally, I hit on chucking a Dremel-sized circular saw blade into a drill press.  That provided a rock-solid platform.  Better still, once the height was set it didn’t vary.  Unlike the abrasive disk, the bricks weren’t heated by the saw blade.  No molten plastic flying around.  Using this method, the bricks required little-or-no touch-up work with a sharp knife.

Two noisy classes coming up in February

Make music – or funny noises – with technology! On Saturday, February 16th, learn to make a soft and cuddly electronic synthesizer, and on Sunday the 17th, use the power of the LAZZZOR to make whistles and ocarinas!

Soft Circuits 2: The SofTone! Saturday, February 16, 2013 from 2PM – 5PM
Learn to use conductive thread and fabric with an inexpensive microcontroller to turn a piece of cloth into a simple electronic synthesizer. No electronics, programming, or sewing experience is necessary – but I’m hoping some embroiderers will take this class and really make something beautiful! All materials are included. Here’s a video:

Click here to buy tickets for Soft Circuits 2 on EventBrite.

Laser Whistles: Sunday, February 17, 2013 from 2PM – 5PM
Just like our regular laser class, only more whistly. In this class, you’ll learn the principles of the computer-aided laser cutter, what materials are safe to cut, and how to create your designs in Adobe Illustrator or Inkscape. Plus you’ll learn how whistles work, and design and fabricate your own! After you’ve taken this class, you’re qualified to use the laser cutter at a discounted rate at NYC Resistor’s open nights. All materials are included, but please bring a laptop with Adobe Illustrator or Inkscape. Here’s some of the whistles we made in a previous class:

LVL1′s UofL Rocketeers build missiles for fun

The first word that comes to mind is “missile” — but this 11′-4″ tall, 43-lb. sky vehicle isn’t used for military purposes. It’s a science experiment. And its designers prefer to use the term “rocket.” There’s a certain giddiness as the various members of the U of L Rocket Team show off their “baby.” The [...]

Milwaukee Makerspace

To Boldly Go Where Many Spaces Have Gone Before!

As of mid-January, the Milwaukee Makerspace is now a member of the Space Federation. The Space Federation is an organization that brings hackerspaces and makerspaces together to share resources and knowledge, while providing non-profit fiscal sponsorship for member spaces.

Space Federation

With the fiscal sponsorship provided by the Space Federation, we will be able to accept tax-deductible donations of equipment and funds from individuals and corporations. We have already been approached by several companies and individuals about helping out the space and the new setup will help us do more for the community in Milwaukee. More importantly, a non-profit structure has always felt right for the space. We collect dues so we can provide an awesome space for the makers in our community. All of our officers and members volunteer their time to make the Makerspace great and no one profits from the space directly – if you discount inspiration and collaboration, that is. The new structure formalizes one of our guiding principles in a way that will hopefully help us do more for our makers and Milwaukee itself.

The discussion to become a non-profit has been an active one throughout our history. Joining up with the Federation gives us experienced folks to work with and a bit less work on our side. We’re excited by the opportunities for the space and the community the Space Federation provides … and we’re in good company! Many of our favorite spaces around the midwest and the country are already members of the federation and we’re excited to start working a bit more closely with them. It’s also nice to work with more local folks – the Federation is based here in Milwaukee.

Things are still getting set up, but if you are interested in working with us in our new capacity, please get in touch with our board!

Build Out In-Progress Pictures

We are super close to re-opening again. We can’t wait to see folks start using the new space. Members and Friends of the Space have been hard at work getting our new space ready for business again.

Even though we aren’t open yet, we’d like to share a couple shots of the space in progress. New Friend of the Space, Rodney, took a few excellent shots of the progress being made a few days ago. Thanks for helping out and thanks for the great shots, Rodney! We’ll have some more shots of things cleaned up a bit more shortly.

As much as we like photos, we are really anxious to open up our doors to Milwaukee again. Hopefully we’ll see you around the new space soon!

Why I’m Registered to be an Organ Donor

TEDxYouth@SanDiego Logo

The critical shortage of organ donors in our healthcare system is the reason I’m registered to be an organ donor and motivates my research to develop suitable replacement technologies in the field of regenerative medicine. Video below! It was an honor and privilege to take part in TEDxYouth@SanDiego, which brought 400 San Diego high school students together to interact and think deeply about the future. It was incredible to speak with so many students who are truly the Architects of the Future.

From TEDxYouth@SanDiego:

Using simple yet illustrative analogies to help non-scientists understand his scientific discovery process, Biomedical Researcher Jordan Miller explains to his young audience how he developed vascular structures through 3-D printing. This exciting research is an important complement to advances medical researchers have made in 3-D printing bioidentical human tissue and organs in the lab. it’s a remarkable prospect for the future of organ transplantation.

Deriving inspiration from a cross section of bread and the sugar structure arcing over his dessert, Dr. Miller describes how he combined his background in regenerative medicine, a passion for the maker movement and reliance on worldwide open sourcing to develop viable 3-D printed vascular systems that he demonstrates actually transporting blood.

Jordan Miller, Ph.D. is a post-doctoral researcher in the Tissue Microfabrication Laboratory at the University of Pennsylvania. Involved with the 3-D maker community since its infancy, Jordan uses a 3-D printer in his work in biomedical research and regenerative medicine and credits open-source collaboration and the maker movement as important contributors to the success of his research.

NYC Resistor

TIMESQUARE watch class

Timesquare assembly animated GIF
Have you ever wanted to wear an Arduino on your wrist and tell the time with a giant LED matrix? Then you’ll love this three hour class at NYC Resistor that I’ll be teaching on February 9th. During the class you can learn how to solder through-hole components as we put together the Adafruit Timesquare DIY watch kit, and afterwards we will extend the watch firmware to add a new feature to the watch.

This class is a great introduction to soldering and some advanced embedded programming techniques. The coin-cell powered Timesquare watch isn’t exactly a normal Arduino and is very CPU limited, so techniques for limiting power consumption, waking up from deep sleep with interrupt handlers, low voltage brownout detection and some inline AVR assembly will be discussed. If you just want to learn to solder and have a very stylish wristwatch, you don’t have to stay for the walkthrough of the firmware.

TIMESQUARE Watch Kit
Included in the class price for every student is a pre-programmed Adafruit Timesquare watch kit and an FTDI cable for re-programming it (a $49 value). You’ll need to bring your own laptop with the Arduino IDE installed to flash new firmware onto the device if you are staying for the advanced portion of the class.

Tama-Go ROM Format

I’ve been continuing to work out the format of the Tama-Go figure ROM. Using the figure simulation circuit I set up in my last post, and a digital logic analyzer, I’ve determined the purpose of most of the data in the figure ROM.

No one say ‘cross talk’ and maybe it won’t happen

 

I started by looking at the game functionality.  It turns out that the functionality is fairly simple, and a very limited amount of the game logic is controlled by data fetched from the figure. The majority of data is images. Near the beginning of the ROM is a pointer table which contains the locations of images used by games, shops, items and other figure functionality. The location of this table is in turn controlled by another pointer at the head of the ROM. The Tama-Go fetches images by first fetching an image pointer from the table, and then fetching the image.

When “GAME” is selected, the Tama-Go starts fetching the needed images from the figure as they are displayed. Interestingly, they are fetched exactly when they are show, and are fetched multiple times if they are displayed multiple times. This suggests that the Tama-Go does not store the images fetched from the figure, but writes them directly to the LCD.

Only two pieces of data appear to affect the logic behavior of the game. The first are the “commands” at  addresses 0×18 and 0×19 (note I’m using a Mametchi figure, this might differ for other figures). These appear to control what game logic the Tama-Go executes when the specific game is selected. It turns out that if these are altered, the Tama-Go can not only jump into different games, but any screen on the Tamagotchi, such as the meal screen, going to the park or taking a bath. If the back button (C) is pressed on any of these screens, the Tama-Go jumps back to the screen it would normally go back to after the current screen, not the figure screen. This suggests that essentially the Tamagotchi acts as a large switch statement or jump table, with no memory of where it has previously jumped to.

I went through some of the possible command values, and found that many of them caused the Tamagotchi to freeze up and require a reset. This is likely because the commands do not exist, or the device is not in the right state for them to work correctly. It might be possible to exploit one of these invalid commands to dump the code of the Tamagotchi, although the lack of debugging information would make it difficult.

Of course, these commands can be used to ‘cheat’ at Tamagotchi. The video below shows this functionality used to ‘evolve’ the Tamagotchi (make it get older).

There is also a series of bytes that gets read at the very end of the game. This seems to be related to how many points the Tamagotchi is awarded for playing the game. The Tama-Go appears to read more data the higher the game score is, so my guess is it’s some sort of cumulative algorithm for calculating the points awarded from the game score. Randomly tampering with these values caused my Tamagotchi to be awarded an extremely large number of points (which was useful in testing item functionality), but I’m still not clear how the values translate to points exactly.

83009250 points has got to be enough for any Tamagotchi

Next, I looked at the shop functionality of the figure. This was also quite simple. The entire store functionality appears to be in the Tama-Go’s internal ROM, and it just fetched the images. The only interesting value was the item price, which can be altered in the ROM. This would probably be more useful had I not just given my Tamagotchi infinite points.

Lastly, I tried using an item, and this was quite interesting. The Tama-Go fetches one byte of non-image data from the figure, from inside the expected segment before using an item, and then fetches more than 200 bytes of non-image data from near the end of the ROM (not the segment, the entire ROM) while the item is being used. This is so bizzare, I tested it several times to make sure it was actually what was happening, and I’m confident that it is.

What I suspect is happening is that the first byte is a command similar to the game commands, jumping to code that relies on both image data and other data from the figure, which it then fetches. I’m not sure what this “other data” is. It could be the location of the images on the screen, it could be audio data (items make sounds) or it could be some type of metadata related to the behavior of the item (for example, whether it gives points, or the probability of behaving a certain way for items that don’t do the same thing every time). As for why this information is at such a strange location, my only guess is that its used by all three characters in the figure, so it can’t be a part of any of their segments. But this is wild speculation.

A complete list of memory addresses I’ve identified is below:

Address Range (inclusive) Comment
0×000001-0×000003 Test command (detects if figure is properly attached)
0×000011-0×000013 Another test command, detects the ‘segment’ controlled by the jumper
