Ride Fly: Segway DIY

August 17, 2010 by Jakob Griffith 9 Comments

The video above is the final working DIY Segway from [sb-scooter]. The website and build log don’t have a lot of information at the moment, but you can still gawk at several pictures of the construction (and a picture is worth 1000 German words).

For those looking for the nitty gritty, with some quick math we figure its two 500 watt motors, powered by 12Ah batteries, will last about 90 minutes. If you’re looking for more details or to build your own, you’re as lost as we are.

Super Simple Arduino Setup Lowers Electricity Bills

August 17, 2010 by Jakob Griffith 38 Comments

An Arduino with 40 lines of code, a temperature resistor, and servo are all that’s truly needed to save some dough with this thermostat by [Peter Hamilton]. LEDs and a potentiometer are added as well to help set and read the desired temperature. With or without said additional parts, the hack is still ridiculously simple and we’re wondering why we didn’t have a similar setup on our blisteringly cold office AC system before seeing it.

Though, we’re going a bit further with our version, plans are in the making to add timers to turn off the system for extended hours while no one is at the office. What would you add?

YM2149 Gets New Life

August 15, 2010 by Jakob Griffith 5 Comments

[MicroMinded] took us way back to our childhoods with his experiments and subsequent YMstream music player based on the Yamaha YM2149 sound generator used in old arcade systems, computers, and even phones (think chiptune). This reminds us of the Chipophone, only this time the sound is achieved from ICs used back in the day, rather than MCU waveforms.

There is still some work to be done to make the music player have a bit more functionality, but for now source is available if you want to make your own. Of course you might come across a small problem; finding an SSG is a tad bit more difficult than say, an Arduino. If a good resource is found, please share it in the comments!

[Thank you Andrew Kretschmer for sending in the chiptune mp3s]

Cybraphon, Rocks Hard To The Mood Of The Internet

August 13, 2010 by Jakob Griffith 13 Comments

Start off with a beat, wood sticks on cigar boxes will do. Add some chimes as accent, a Farfisa organ or record player for a voice, several other instruments for harmony and dissonance, and you’re still just on the tip of the iceberg for understanding Cybraphon.

Not only is this antique wardrobe completely autonomous, playing music with over 60 robotic instruments, its song are based on the current mood of the internet. You definitely don’t want to miss the video (or pictures) on this one, catch it after the rift.

2 Foot Tall POV Globe

August 12, 2010 by Jakob Griffith 18 Comments

[Ytai] let us know about his POV globe, all four parts of its current progress. While he says he was inspired to write up the project from a YouTube clip, we know the real reason. Regardless, the plan is to have a 2 foot diameter globe with 256 LEDs spinning at 50 revolutions per second streaming images from an SD card using SPI. While the project isn’t completed yet, we know [Ytai] will pull through like he has in the past, and you can be sure we’ll keep you up to date on his progress.

Out Now: EL Coat, Coming Soon: EL Hat

August 10, 2010 by Jakob Griffith 41 Comments

[Render] says his coat is simply “enhanced with EL wire”, but we know the truth. He’s secretly an alien that can’t block out all of his glowing green skin with a the black coat. No? Fine,

You can put away the sewing machine, [Render] simply used a needle and fishing line to attach ~50-70 foot of electroluminescent wire to the outside of a coat he picked up at a local clothing shop. Solder and program in an inverter and controller board thanks to SparkFun, and you’re ready to go.

Just double check all your connections, high voltage directly on your person is not fun. Trust us.

Spin Peggy, Get 3D POV

August 9, 2010 by Jakob Griffith 19 Comments

We put a temporary ban on posting POV projects after receiving several LED spheres back in May. But we had to lift the injunction after seeing this superb Volumetric 3D POV display by [Wes Faler] and [Don Smith].

Their creative use of several readily available components adds to the alluring setup; the central elements being just a box fan and Peggy kit from EMSL. The video after the jump doesn’t really do the project justice, but if you missed it at Maker Fair Detroit and can’t make your own it’s the best you’re going to get.
