It’s finally here, the last episode of Scion’s Take on the Machine with Mitch Altman. In this episode all the teams are given a recap over their success and failures, and the clear winner is placed on top. We’re not ones to spoil the surprise so you’ll just have to click the link and watch to find out.

But lets take a moment to remember each team, The Transistor and their live action zombie game. Crash Space and their musical building. Pumping Station: One and their ice cream maker. Artisans Asylum and their breakfast machine. And lastly, NYC Resistor and their drink mixing slot machine.

Who’s ready for next season? There isn’t a next season you say? Perhaps a new influx of sponsored hackerspace competitions will spring up, or the whole concept will die out as quickly as it came. Either way, it’s all about the money fun and educating experience, right? And that’s all that matters.

[Thanks Deven, sorry you guys didn't win.]

It only took 4 hackerspaces, but we finally get to see a zombie movie inspired project; hackerspace The Transistor Takes on the Machine with a Dawn/Shawn of the Dead movie theme. Race cars disguised as zombies swarm toward the players, who then use laser tag like guns to “shoot” down the approaching undead. The whole thing is a mess of Arduinos communicating with xBees to a central iMac G3, but it all comes together rather well and is promised to be released open source.

Now all that’s left is deciding which hackerspace wins the competition. Who do you have your money on?

This overly large magnet certainly completes the mad scientist look (for an even crazier look, take a jar of water with red food coloring and place in one large cauliflower, instant brain in a jar).

The base of the magnet is painted foam cut with a makeshift hot-knife; to get the magnet sparking [Macegr] laser etched acrylic with a fractal pattern and embedded LEDs in the ends of the acrylic. An Arduino handles the flashing LEDs and also produces a 60Hz PWM pulse for the spark’s hum. The end result is satisfyingly mad, and while practicing your evil ominous laugh catch a video of the magnet after the jump.

While this mechanical mustache isn’t made for a Halloween costume, it certainly looks like part of one. Copper clad, brass, cable, and a few other bits come together in a similar style to tension based hands; the piece is then worn much like a Mardi Gras mask. To complete the rustic “old tyme” look [John] was after, the copper was tarnished using the vapor from a vinegar and salt solution. The finished assembly is steam punk delicious, but we’re saddened by the lack of steam punk eye brows to complete the look (or steam punk mutton chops, or steam punk goatee, or…)

Do people enjoy wasting 300$ on a bulky convoluted system, that only works for special “Teacher Edition” calculators, and is several years out of date; E.G. the TI-Presenter? [Benryves] certainly does not. So instead of purchasing a TI-Presenter, he made his own TV out system for the TI brand of calculators by using an ATmega168, a few passive components, and some clever code. The only draw backs being: you save 280$, it fits in your pocket, and it works for almost any TI calculator. Bias aside, the system does actually have a few caveats compared to the commercial edition, but the pros far outweigh the cons.

You’ll probably lose your appetite after watching part one and part two of Artisans Asylum as they Take on the Machine. Based around the Wallace and Gromit “automated” set of contraptions, the team from Boston set out to make their own breakfast machine. Of course, with only three weeks to work it didn’t exactly turn out as planned. They certainly had some good ideas though, and we were amazingly impressed at their egg cracking machine. But in the end, we wouldn’t want to be first in line for a plate of breakfast. Next is the final team, The Transistor, who will be making a live action zombie video game.

[Ben Heck] is in the Halloween spirit with his Portal inspired “see through” t-shirt. That is, a thin lcd is mounted on [Ben's] chest, with a not as thin camera mounted on his back; when the system is running, everything behind him is captured by the camera and displayed on the LCD. The concept isn’t exactly new by any means, often by the name of “gaping holes” or “hole through body” or more, but the project goes to show that a creative costume isn’t always the most elaborate, expensive, or even a new idea. Catch a video of how to make your own Portal shirt, after the jump. Oh, and you can win the Portal shirt here.

The above is a specially designed game controller made by [Giorgos] solely for the RTS game Men Of War (now that’s dedication to a game). [Giorgos] started off with a rough breadboard and 11 buttons. Slowly overtime he included a joystick, countdown timers, and the wonderfully lit case. Under the hood is a couple of PIC microcontrollers multiplexing the switches, LEDs, timers, and also interfacing with the computer via how is it not dead yet PS/2 port. The build log is a very detailed read and well worth it, even if you’re not planning on making a custom controller. [Ben Heck] better watch out, there is a new controller making enthusiast on the loose.

What weighs more than 500 pounds, produces 500 kilovolts, and we don’t recommend you try at home in any way shape or form? If you guessed a rock disaggregation device, you’re correct! We also accepted lightning generators as correct answers. Using high voltage electricity, a rock can be split apart down to its grains without destroying the precious minerals inside; unlike traditional grinding and mechanical techniques that often ruin the sample. All it takes is a massive hydro pole transformer, five 1uf 100 kilovolt capacitors, eight hand wound inductors, and two massive cojones to stand within 20 feet of the thing while it’s going off. Video after the divide.

It’s that time again, time to take on the machine with the Hackerspace, Crash Space (and part two)! The team of Californians set out and successfully turned the front of their building into a musical instrument, similar to [David Byrne's] Playing the Building. When a pedestrian walks by they set off distance sensors, which in turn actuate mallets that strike particular objects to produce a tone. We were pleasantly surprised at how interactive the installation was, even if it didn’t sound that great. But will it be enough to beat out the previous two teams? And how will it do up against Artisans Asylum’s not what you’re thinking Breakfast Machine next time?

There are a lot of solutions to programing an Arduino: the default avr-g++, Studio, etc. But [Sandeep] let us know about using one of the more powerful IDEs out there, Eclipse, to do the same. We’ve already outlined why Eclipse is a great IDE but now the fact that you can use it in your MCU based projects adds to its usefulness and already large feature list. However, don’t be turned off by [Sandeep's] tutorial. While it is aimed at people who are completely new to setting up an IDE and working with an AVR, the tips certainly can benefit even the most experienced hacker.

The back story behind [Mike] experimenting with plants as AM radio transmission antennas antennae is rather interesting and worth the short read. But for those who just want the facts, [Mike] took an ATMega324, modified the PWM output into a sinusoidal AM signal (using a simple form of RLC circuitry), and connected the circuit to a plant no plants were harmed in the making of this project. The results? Well we’re not ones who would spoil the surprise, you’ll have to see for yourself in the video after the jump.

Non acronym version of the title: send and receive text messages via cell phone communication towers using an Arduino or other microcontroller. “We’ve been doing that for years!” you cry, well yes, technically. But [Fincham] lays it outs simply; commercial offerings are expensive and finding a cell phone that uses RS232 now a days is getting difficult, so a new way of doing the same old is necessary. The good news is USB GSM modems are readily available, cheap, and only require a few interface pins to get them talking with an Arduino. In fact, the image above is all you need.

Sadly, this pocket mp3 wav player doesn’t come close to the capabilities of even an iPod generation 1 yet, but you have to give [Owen] props for making it in less than 24 hours. The system consists of a Propeller MCU (cleverly wired to be swappable with “shields” similar to Arduino systems), SD card for song storage, and an LM386 for audio. While the setup is a little dull, and only plays through songs non stop with no controls whatsoever, it certainly is a good start in the right direction for a cheap and simple portable music player. Of course some planned changes are in the works, include an accelerometer (gesture based controls?), etched PCB, docking station, and a case. We’re surprised there is no form of screen planned, considering Owen appears to have a rather good handle on touch interfaces; perhaps he’s waiting for revision 3.

Part one and Part two of Hackerspace Pumping Station: One taking on the Scion challenge are up and ready for your viewing pleasure. The team at Pumping Station: One built a Tron themed bicycle that when setup properly, would churn ice cream that turned your urine neon in about 6 minutes by using dry ice and ethyl alcohol. Besides sounding not so tasty, and having a multitude of problems along the way, the project turned out the be a success. The question becomes, does it stand up to the last Hackerspace, NYC Resistor, who made a drink mixing slot machine? And how will both fair against the up and coming Musical Building by Crash Space?
