Morse code keyboard

USB Iambic Morse Keyboard
Have you switched your QSOs to PSK31 or some other digital mode, but miss the joy of sending CW with an iambic paddle? Then here’s a project for you.

CQ CQ CQ
Bill Ward (KD4ISF), Guy Dickenson (KD7TJJ) and Dave Clausen (W2VV) setup a club call sign N2YCR and a remotely operated computer station running fldigi for PSK31. The machine is in the backroom at NYCR and can be operated by members with general class amateur radio licenses from anywhere, using xvnc to display the fldigi application.

PSK31 at NYCR
But operating it with a keyboard has none of the feel of an old fashioned QSO, so I designed an interface for Dave’s BY-1 Bencher Iambic Paddle. Iambic paddles are very different from straight keys in that they have two inputs: one for “dit” and one for “dah”. If an input is held in, it will repeat at a pre-programmed speed. If both are held in, they will alternate between the two symbols. Typically the dah is three time as long as the dit.

USB Iambic Morse Keyboard closeup
The paddle itself doesn’t generate the code; this is the responsibility of the radio, or in this case, of the Teensy 2.0. It runs a state machine that listens for PIND4 to be pulled low to indicate a dah, or PIND5 to be pulled low for a dit. If neither is pulled low within the time of two dits, the current bit-stream is looked up in a table and if there is a valid USB keyboard event in the table it will be sent to the host computer.

With a straight key the computer would need to estimate the codes per minute and try to differentiate dits from dahs. But with the iambic paddle, the operator has input the separate symbols so there is no difficult step to determine the code. This makes it feasible to run the entire decoding stack in a small microcontroller like the ATMega32U4.


Sending CW without audio feedback is very hard, so a tone is produced via PWM on OC0A at 498 Hz, directly into a speaker scavenged from an old headset. Software controls the volume in a crude fashion by limiting the on-time of the square wave. If the input sequence is not a valid Morse code, the timer 0 is switched to a slower speed, which causes OC0A to be driven at half speed, or 249 Hz, which will indicate an error tone.

Full source for the Teensy is available for your own use. It should appear as a generic USB keyboard and work with any application.

Making boxes
The case is made using my laser cut box generator and available on Thingiverse. I cut it using 6mm clear acrylic at 100% power, 4% speed, and etched the raster at 100% power, 20% speed. The box is a friction fit and holds together without any screws or glue.

Some possible improvements are to have an external potentiometer to control the speed of the CW (currently it is a compile time constant), and to create a USB serial device that translates its input into audio so that you can have a full CW QSO with fldigi.

Laboratory B

Transparency Grenade

The lack of Corporate and Governmental transparency has been a topic of much controversy in recent years, yet our only tool for encouraging greater openness is the slow, tedious process of policy reform. 

Presented in the form of a Soviet F1 Hand Grenade, the Transparency Grenade is an iconic cure for these frustrations, making the process of leaking information from closed meetings as easy as pulling a pin. 

Equipped with a tiny computer, microphone and powerful wireless antenna, the Transparency Grenade captures network traffic and audio at the site and securely and anonymously streams it to a dedicated server where it is mined for information. Email fragments, HTML pages, images and voice extracted from this data are then presented on an online, public map, shown at the location of the detonation. 

Whether trusted employee, civil servant or concerned citizen, greater openness was never so close at hand..

...And Idea who's time has come!

Dome If You Want To

Tonight, we assembled our new 16′ diameter PVC dome. The result of two solid Saturdays of work, it came together beautifully. Now we just need to disassemble it and move all the furniture back in before tomorrow’s class…

The members are 1″ PVC pipe. We flattened the ends by heating them briefly in the kiln…

… and clamping them between two handy bits of heavy metal.

A few minutes with the drill press to finish them up…

Installing the top
… add a few bolts, washers, and nuts to flavor.

Dome view
And then take it all down to adjust the angles…

Installing the top
Put it back up…

Complete dome view
Just a few more bolts, and there you are. All dome!

Now you can dome in the morning, you can dome at night, you can dome when you wanna dome.

I will give a talk titled “Introduction to IT Security”. Many people are interested in the area or see it as the great unknown. This will be the beginning of a series of talks that will take place in TOG covering the area of IT Security and all it’s ups and downs.

I will also be running a Wireless Security Workshop where I will set up wireless networks to be attacked and go through the process of doing so as well as explaining the reasons why the attack works.

The talk is directed towards students considering a career path, people currently employed and looking for something new, or just someone who sees it as something interesting and would like to see what it is really about. I will cover a lot on the night so I will not be going into any great detail or going too low level, but other topics will be covered in greater detail in other talks in the series. I have allocated 1 hour and 30 minutes for the talk but I will not be presenting all the way though. The floor will be open to questions throughout the talk.

For the workshop I will using information that is freely available, some since 2001, I am simply structuring this into a session where I will present an attack, and attendees will give it a go. We will be looking at open wireless networks, WEP and WPA encrypted networks. 4 hours has been allocated for this session. This tutorial is hands on and everyone is encouraged to help one another. Requirements for the session will me mailed to the registered attendees closer to the time.

For booking a place or other questions, please use the forms below.

Only book if you are sure you can attend. Places are limited.

I have hit the total allocated space for the IT Security Intro, so any further submissions will be for a waiting list. I will re-count the seats for the event at the weekend and mail people on the waiting list directly

BikeHood, February and March

Throughout the winter, BikeHood has been running for those brave enough to keep cycling all the way through the cold weather. Seriously, once you’ve been out there for a few minutes, just about any weather is warm on a bike!

The next one will be at the Hackspace on February the 18th, from 12:00 – 17:00.

BikeHood is not just about getting your bike repaired, but learning how to look after it yourself. It’s been going from strength to strength, and we’re on hand to teach and help you get your bike up and running. Even the most complex bits of bicycles aren’t so scary when you’ve got them apart and know how to put them back together.

As well as work stands and a large selection of bike tools, we have resident experts ready to help you fix your bike and get it back on the road (or the trails). Whether you’re a complete beginner or an old hand, you’ll find a friendly group of mechanics and cyclists with a well equipped workshop. Though future events will be ticketed, all we’re asking for now is a voluntary donation to the Hackspace in return for us helping you to fix your bike.

We’ll have more announcements to make about the March event.

Global Game Jam 2012

The Hackspace recently acted as a Global Gamejam 2012 venue, with about 25 people descending on the space for the weekend to make games.

In case you don’t know much about the making games, modern console games take between eighteen and twenty-four months to create. The challenge of the Global Game Jam is that these teams had just two days to make something, so… a pretty tight deadline! We had seven teams compete in all, including local companies IndieSkies and Nerf Games.

As well as myself (David H), hackspace members Andrew Armstong and Andy Thorpe helped to make sure everything ran smoothly. While the teams cracked on with their projects, we also played quite a bit of Johann Sebastian Joust. Below are shots and a video from a couple of the projects.

Andrew Roper from IndieSkies writes:

Quest for Indimmortality is a game where you, a budding alchemist, are fantasizing over creating the philosophers stone, a rare and hard to create item. You start out with basic ingredients and some metal, and have to combine ingredients in the right equipment to be able to produce more valuable metals. Eventually you’ll create the philosophers stone and gain Immortality. Developed by Ryan Simpson and Andrew Roper, music by Gavin Harrison.

Unfortunately, the game wasn’t able to be completed over the 48 hours, though there are plans to continue development in the near future.

Also by some developers from IndieSkies and sent to us by Lewis Moore, Causality:

The most fun thing about that one during the jam was watching their artist mess around with the assets.

Game jams aren’t really about making a polished game, which would be impossible, they’re about roughing out a new idea. Confining development to such a short timescale means that a team can try out some really risky or strange ideas for games, without wasting a huge dollop of a studio’s time and resources to make something that ultimately doesn’t pan out.

We’re looking forward to hosting more of them at the hackspace.

Geeky Valentine’s day Ecards from the US Patent Office

A few days ago, one of our newest members, @dustynrobots shared a link to some amazing Valentine’s day cards with the rest of the group.

These amazing Valentine’s day cards for makers by Steve Hoefer are sourced from old public domain US Patent Office. They’re awesome and hilarious, and have inspired us to make a few things.

First, it got me to make the ecard site that I’ve been thinking about for a while now. Postkin’s GeekCards are free, funny ecards for the geeky people in your life. These cards were so amazing, once Steve agreed to let me use them, I had to get the site built in time for Valentine’s day!

Now that the site is built, I’ll be adding more geeky ecards for other events soon! It’s also flash-free and built on web standards so you can actually view the cards when you get the email on your phone.

Hope you enjoy the ecards, and if you have ideas for other geeky ecards we can create, please let me know!

In the meantime, Trammel has been working away on letterpressed editions of these cards on our Intaglio press. Hopefully we’ll have some more pictures of the process and finished cards soon!

Valentine's day cards

Trammel has a great writeup on using the letterpress, but if we pester him in the comments and maybe he’ll do a post about the process of making these plates and some of the other amazing new stuff he’s been up to with the letterpress lately!

Pictures from the Welding Class

Just finished the Saturday series of welding classes at My Inventor Club. Matt from Freeside taught this one, but Shane from MIC does a series too.
Here's Newt on the MIG while Charlie and I are playing around with aluminum on the TIG.
Gloves and trendy jacket belong to the house, I just had to bring the glasses. Ear plugs may be a good idea too.

Here I am, grinding down a piece for an ugly, abstract sculpture to practice on.
All in all, we learned and then got to play with Oxy-Acetelene welding and cutting, grinding, portable band saws, MIG, Stick, TIG, and cut-off wheels. I came in with no experience and left with at least enough knowledge to not burn my own eyes out.

According to Matt, they do the classes as 3 weeklies on Wednesdays, Thursdays, or Saturdays with 2-4 person groups. Drop a line on the Freeside mailing list if you're interested and they'll put together a class.

Event: Art Hackathon @ Hive76, March 10th and 11th, 2012

Hive76′s Art Hackathon

March 10th and 11th, 3pm to 7pm

For the second weekend in March, Hive76 is hosting a day of smashing, cutting, gluing, taping, painting, and general making and frivolity. We’re calling it “Art Hackathon”. Inspired by the Bravo TV Series Work of Art, and following closely in the footsteps of Art Hack Day, the event will focus on the rapid creation of meaningful works of art out of a provided supply of recycled materials.

Hive76 will provide massive piles of cardboard, tubs of glue, masking tape, tubs of spackle, box cutter blades, and a few cans of various colors of spray paint, to let every participating individual or team create a work of their choosing. The works will be based on a single theme, to be announced at the beginning of the event.

The event is split across two, four-hour days. While participants are free to use the time as they wish, the time is designed to provide time for planning on and a moderate amount of building on the first day, with some drying and curing time overnight before finishing up the next day.

A fee of $25 per person will be charged at the door, to cover the cost of materials and food that will be provided during the event for both days. Please RSVP for the event before March 6th by emailing smcbeth@hive76.org.

How I Made the Art Hackathon Image

What is art? To me it has always meant indirect communication–the implied conveyance of ideas through conventions of shared culture. Anything is fair game for a medium, and anything can be a potential message; thus art is infinite in both dimensions.

So with that in mind, I wanted to create an event that epitomized the nature of creativity, of “art”, in a way that was familiar to me. And I wanted to make a kind of logo to go along with it, to be memorable and ‘cuz logos are just fun and I want the event to be fun.

I began by searching on DuckDuckGo for familiar imagery for the concepts of art and hacking. For art, the image of the paintbrush and pallet was very common. For hacking, the skull and crossbones shows up. Well, for hacking, photos of people sitting around tables, staring at computer screens, completely oblivious of any photographers in the room, was also quite common, but that’s rather difficult to capture in a logo.

I did a few sketches on paper of the idea of a Skull and CrossBrushes, but it was too simple and too cartoony. I need something that is stonger, with a lot more color. At this point, I got an idea. The event will feature construction of 3D elements, so maybe the logo could be constructed in 3D as well. I began a crawl through Thingiverse, looking for the perfect skull model. I knew that a skull should still be the basis of the piece, but I had a few ideas other than just “crossed brushes” to bring it back to “art”.

And then wonky hotel WiFi stymied me for about an hour, but that was okay, I had some laundry to do.

When the WiFi came back, I went back to looking for the skull. This is what I found.

Elvis, a printable skull

 

That looked like a pretty good skull, and I knew that starting with a model that was good for printing probably meant that the geometry was solid enough to do a 3D rendering. I then goofed around in Blender until I got something that would serve as a good start for some more work in Photoshop.

Le Skull

To make the cross, I searched for some more images through DuckDuckGo, and found a suitable brush and screw driver. Over in Photoshop, with a few applications of the Posterize command, some Hue rotation, some Outlines and Drop Shadows, a little text, it was pretty much complete!

Crafty Computer …

Back-lit view of paper and foil micro-controller board

After visiting The Hacktory’s “Soft Circuit” event, PJ and I were inspired to take a stab at making some micro-controller circuits using alternative, “high/low tech” approaches.  PJ made an MCU circuit using conductive paint (has potential, but needs some tweaks).  I opted to try a circuit board using metal leaf.  That happened to work on the first shot — although careful scrutiny of the picture on the left suggests there was some luck involved (there are holes in the circuit that come dangerously close to wrecking it).

Looks good from this angle and all the connections check -- you'd never guess it was hanging by a thread ...

I had considered using scored foil as a way to make free-hand, one-off circuit boards for quite some time — but until recently, I never had the mix of free time and raw nerve to actually try it.  It turns out that my reservations were probably well-founded, but it also happens that the technique is workable, and the results are actually aesthetically interesting.

We decided to make the board in a hexagonal shape (Hive76 — hexagon — get it?). First, we prepped circuit board material by spraying adhesive on card-stock and then sticking the faux gold-leaf on the prepared surface (this sounds simple, but the foil is maddening stuff, so the process involved profanity and a certain amount of despair).  Then we cut the foiled card-stock into hexagons. After that, we cut out a rectangle where the IC was going to go, so that there were no conductive paths under the chip.  Once the board was roughly prepped, we made a “squashed bug” of the IC , splayed its pins out, and soldered it to the gilded surface.  Using the gaps between the pins as a guide for an exacto knife, we cut free-hand traces that routed the pins of the chip to large zones on the edge of the hexagon (I was a little surprised that the cuts were free of bridges). Finally, we soldered a capacitor between the MCU’s Vcc and ground and soldered a 47k resistor between Vcc and the MCU’s reset line.  At that point, we had a working circuit that was in-system programmable — at least in theory.

Unfortunately, I had no idea how we might program the MCU or hook it up to external circuitry without damaging the fragile structure.  PJ came up with the idea that made it all workable … magnets.  All really good magic is done with magnets.  The idea here was to place the paper computer on a steel surface, which allowed us to stick magnets wherever we wanted to make a connection.  With steel under the circuit, the down-force of the magnets gave us firm-but-gentle electrical contact with the delicate foil. Once the magnets were in place, we only needed to touch alligator clips to them — since the clips were steel, they stuck happily. With the clips secured to selected points on the MCU, we were free to connect the opposite ends of the clips to the various external items needed for the circuit.  Note the ingenious use of paper-clips.  PJ again — see a pattern here?

Our first connection was power (two magnet connections, one for +3.6 volts, the other for ground).  Then we hooked up the Spy-bi-wire programming interface (two wires, two more magnets).  After that, we wrote the obligatory “blink LED” program and loaded it into the paper computer.  Naturally, we wanted to see the results — two more connections for the LED terminals and — Voila!  Here’s the movie …

TOG

Space Open/Closed project

We are now live on Hackerspaces API. This project is based off a Bifferboard running Debian that checks I/O port 11 on the Bifferboard to see if its connected to knife switch. It then connects to websites and updates every minutes with status if space is open or closed. Great bit of hardware and cheap enough for something with IO. Next step is to connect to IRC to update channel with status. More details on wiki.

Hacking the Gilson

Like playing chase-the-laser-pointer with a kitten.

After a couple weeks of hacking on the Gilson we have PID* control.

When we first saw the Gilson, we didn’t have access to any feedback mechanisms. All we had were panic stop modes of control. After a ton of experimentation, and Nick reading five control theory books, we are having fewer incidents in which someone yells “Holy Crap Make It Stop Before It Destroys Itself!” It’s not yet a null set, but the cardinality is significantly reduced.

Shop Sunday Shows off its Threads (Feb 12 at Noon)

 Calipers are Nifty

Crash Space has a whole new Bimonthly Event called Shop Sunday, focused on exploring the tools and methods used to make everything from toasters to rockets.

This week’s Shop Sunday will be all about Threads!. Tapping, Die Cutting, and using a lathe to cut threads, will all be demonstrated and you’ll even get to tap and fit check a hole! We’ll also go over the various uses and applications of threads, from ball screws and power screw applications to fasteners and Bolted Sections. We should be covering the basics and simple equations, and also go into more depth for things people are interested in.

(not really cutting threads in this image)

Maybe we could cut some threads on the lathe?

Shop Sunday is hosted by Kyle Cothern, a Launch Ops Engineer from SpaceX who has 6 years experience working in development shops for various mechanical design projects.

Shop Sunday will  start at noon and go till 3pm on February 12th, and will happen every other Sunday in an ongoing fashion, similar to Radio Mondays. It’s free for members and a recommended contribution of 15$ for non members. Topics covered should eventually teach anyone interested how to use the tools available at the space. Special Projects crop up once every month or so as well.

Look at this sweet Crash logo, must be CNC or something

Made in the shop at Crashspace!

If you’re interested in hosting a Shop Sunday, or would like a specific topic covered at one in the future, let us know! The meeting will be an open format for interested tinkerers of all experience levels who like getting their hands dirty with design and fabrication of mechanical widgets.

Happy Friday too everyone!

Next buildout is scheduled for March 3, 10:00 AM - 6:00 PM. For those not in the know, Buildout is when Freeside's members get for the purpose of making the space better, socializing, and eating food. Incidentally non-freesiders are more than welcome to show up, help, socialize, and then *maybe* become members afterward. Buildout's a great time for anyone to show they care for the space.

If you have an idea for what needs worked on, please add it to the task list here:
https://sites.google.com/site/freesideatl/build-out/to-do

If you need something for said task, such as a ladder, please feel free to add it to the list here, and we'll try our best to see it shows up.

Science Report: Hexayurt model, osmocom cable, remote control tricks

We have been silent for a while; the winter is quite cold here. But, hey, let’s brag instead! This week’s Tuesday meeting saw diverse activity:

When we were done with the photo box and the scale model, we had to store them somewhere. The photo box sits in the ceiling, on top of some well-insulated pipes. The model was dismantled, to be re-built and perhaps even painted, at a later date. Needing a Barbie to stand next to it.

In the near future, we will host a Saturday Forsk – yes, the plan is really to host one once a month. A Saturday Forsk is a prolonged slack event with a theme. The upcoming theme is “Luften är fri”. (Thanks for the name, we will only borrow it, Sparvnästet!)

P3D.in is a new beta service (currently free, prolly will change) for rendering 3D models in the web browser, no flash or plugins required. I guess it works via HTML5?

They only take .obj files at the moment (which you can export to from Blender). It’d be much much more useful if they automatically imported STL files, and all of Thingiverse, among other sites. I’ve logged a bug report and feature request along these lines.

Here’s a yoda head converted to .obj and imported and hosted by P3D in their demo iframe. pretty cool. (NOTE: I guess it needs a while to load in the browser, apparently. So if it’s not showing up yet in your browser, give it a minute).

When life gives you busted up old LCD panels, make… lightboxes! I constructed this one out of the CCFL backlight from an old laptop LCD I found around the space. It gives a nice, even white light, and runs off a 9V at about half an amp.

The inverter for the backlight was long gone, so I replaced it with one of these inexpensive CCFL inverters from MPJA.

A little hot glue and acrylic cement later, we have a perfectly serviceable lightbox. Now, what ever could we use one of those for?

Never Buy a Dust Cover Again

New Printer, right next to sawdustgenerator

Here at Hive76, my desk sits right next to the wood working station. Normally, this isn’t an issue because my computer uses passive heat management, so there is no risk of getting dust clogged up in the fans. But I recently bought a new printer and want to keep it nice and clean. I initially thought of buying a dust cover, but serendipitously completely forgot to even look for them before I left the store. So, necessity being the mother of invention that it is, I was stuck in the space, not wanting to hop back in the car for a silly little dust cover, when I realized that I had a useless cardboard box that I was about to discard that was almost the exact dimensions of the printer itself. Duh! The box it came in! I cut one side off of the box, taped the corners down, left the hole from the missing flap for the wires coming out of the back of the printer, and voila! A free dust cover. I suppose if the color ever bothers me I can just spray paint it a solid color. This solution is actually better than a real cover because now I can stack papers and other lite objects on top when the printer isn’t in use and not have to worry about them sliding or rolling off because of the somewhat round top of the printer.

Blender used to Render cover of Nature Chemistry

Christopher Wilmer from Northwestern University just got published in a leading chemistry journal, Nature Chemistry. Congrats Christopher! To convey his scientific findings to a broader audience, he designed this artwork that made it on the cover of the journal. Open source science and art FTW…

Check it out!
http://www.blendernation.com/2012/01/27/blender-used-to-make-cover-art-for-nature-chemistry/

And here’s the Nature Chemistry paper.

Cover art Summary:
Randall Snurr and co-workers describe a computational approach for simulating every possible metal-organic framework (MOF) that can be built from a given set of building blocks (metal clusters and organic ligands) — represented conceptually on the cover using Tinkertoys. Some of the properties of MOFs can also be simulated to uncover structure–property relationships or materials suitable for specific applications. The MOF shown on the cover was identified for its methane storage capacity — a property that was subsequently confirmed experimentally.

Paper Abstract:
Metal–organic frameworks (MOFs) are porous materials constructed from modular molecular building blocks, typically metal clusters and organic linkers. These can, in principle, be assembled to form an almost unlimited number of MOFs, yet materials reported to date represent only a tiny fraction of the possible combinations. Here, we demonstrate a computational approach to generate all conceivable MOFs from a given chemical library of building blocks (based on the structures of known MOFs) and rapidly screen them to find the best candidates for a specific application. From a library of 102 building blocks we generated 137,953 hypothetical MOFs and for each one calculated the pore-size distribution, surface area and methane-storage capacity. We identified over 300 MOFs with a predicted methane-storage capacity better than that of any known material, and this approach also revealed structure–property relationships. Methyl-functionalized MOFs were frequently top performers, so we selected one such promising MOF and experimentally confirmed its predicted capacity.

Nottinghack

New donations to our bookshelf (Jan 2012)

This month we’ve got some notable new books for members to read in Nottingham Hackspace.  The classic ‘Drawing on the Right Side of the Brain: A Course in Enhancing Creativity and Artistic Confidence’ by Betty Edwards claims to be the world’s most widely used drawing instruction book and has cracking reviews. We also have a brand new book, ‘How Round Is Your Circle?: Where Engineering and Mathematics Meet’ by John Bryant, which describes some beautiful physical models you can build to explore mathematical problems from an engineering perspective.

These donations were made by David Hayward (and by me). If you have any interesting books gathering dust on your home bookshelf, please consider lending or donating them to the hackspace. I will leave you with these descriptions of our new books, from their publishers:

Drawing on the Right Side of the Brain (front cover)“Whether you feel you have little talent and you doubt you could ever learn, or you enjoy drawing but have not been able to get much beyond a childlike level, this book will give you the skill you have always wanted. If you are already drawing as a professional artist or artist-in-training, it will give you greater confidence in your ability and deepen your artistic perception. This 20th-anniversary edition of ‘Drawing on the Right Side of the Brain’ has been dramatically revised, with more than fifty per cent new material, including: Recent developments in brain research that relate to drawing. New insights on the use of drawing techniques in the corporate world and education. Instruction on self-expression through drawing. Ways to step beyond black-and-white drawing into colour. Detailed advice on applying the five basic skills of drawing to solve problems.”


How Round Is Your Circle (front cover)How do you draw a straight line? How do you determine if a circle is really round? These may sound like simple or even trivial mathematical problems, but to an engineer the answers can mean the difference between success and failure. How Round Is Your Circle? invites readers to explore many of the same fundamental questions that working engineers deal with every day–it’s challenging, hands-on, and fun.

John Bryant and Chris Sangwin illustrate how physical models are created from abstract mathematical ones. Using elementary geometry and trigonometry, they guide readers through paper-and-pencil reconstructions of mathematical problems and show them how to construct actual physical models themselves–directions included. It’s an effective and entertaining way to explain how applied mathematics and engineering work together to solve problems, everything from keeping a piston aligned in its cylinder to ensuring that automotive driveshafts rotate smoothly. Intriguingly, checking the roundness of a manufactured object is trickier than one might think. When does the width of a saw blade affect an engineer’s calculations–or, for that matter, the width of a physical line? When does a measurement need to be exact and when will an approximation suffice? Bryant and Sangwin tackle questions like these and enliven their discussions with many fascinating highlights from engineering history. Generously illustrated, How Round Is Your Circle? reveals some of the hidden complexities in everyday things.

Hive 76

Art Hack Day in Brooklyn

The MAKE blog recently posted a notice of an event being held this weekend–Art Hack Day–that I find very intriguing. I’ve been bandying about an similar idea, in part inspired by the Bravo Channel’s reality TV series Work of Art. The show has the typical “Top XYZ” format of elimination challenges. What strikes me about the show is that their work space looks very much like a hackerspace, and once the artists settle in to the work format, they start producing some extremely intriguing pieces.

In a lot of ways, the artist’s studio and hackerspaces are very similar; indeed, we here at Hive76 have made a former artist’s studio as our fire-retardant-home-away-from-home here at 915 Studios. So with that in mind, we are putting together a similar event to the Art Hack Day. We would like to make it an open build session with recycled materials. Stay tuned for the full details in an upcoming blog post (honestly, I will write it, really, I will).
