“What’s got 6 eyes, 6 fingers, 6 brains and plays Guitar Hero III? If you answered ‘The Beast’, you’re close. It’s actually the Guitar Hero ‘bot’ that I’ve been building around 6 Arduino cores (Boarduinos actually). It uses 6 photodiodes mounted on a LEGO rig to ‘see’ the notes on the screen and drives a wireless XBOX 360 controller through a series of 6 Reed relays in real time. So how does it perform? Right now, with some quick and dirty code to decode and play the notes, it’s tuned to play Medium-difficulty songs with a hit ratio between 80% and 90%. The bot also controls ‘Star Power’ by itself when it’s charged enough. I have high hopes that with some more work, it will be able to handle Expert-level songs with good results. I’ll post a demo video of the bot playing GH 3 later this week. ”
The monome is a gorgeous, minimalist, open-source light-and-button pad used primarily by musicians as a controller. The folks over at SparkFun Electronics, inspired by the monome, released their own button pads and circuit boards, only they designed theirs to be able to hold RGB LEDs. They made this nifty Tetris game with their parts. Looking at it, though, I noticed something: they only seemed to use a limited palette, in particular, they only appeared to have red, green, blue, cyan, magenta, yellow, and white, corresponding to channels being fully on or fully off. I wanted to see if I could get colour mixing, wherein channels were on partially in order to blend colours smoothly.
WinAVR was compiled with a 2 year old version of libusb (v0.1.10) instead of the most recent version (v0.1.12), which means that it is incompatible with the original driver that I posted up on the USBtinyISP download page. Thus if you want to use the latest WinAVR, you must uninstall the driver and then reinstall the older (v0.1.10) version which is now available on the download page.
Otherwise, youll get a nasty surprise:
as the device seems to be working, but avrdude can’t “find” it!
If you don’t want to reinstall the driver, you’ll have to replace the avrdude.exe and libusb0.dll with the modified versions (also available and described in detail on the download page).
The other bad news is that I made some mistakes in the code that make it incompatible with 64-bit. Hopefully I will get that tested/fixed for the next revision…not having a 64 bit machine makes it a bit annoying to debug!
Thinking about the Arducopter project I posted about yesterday, as well as the RepRap project…I thought how useful it would be to be able to wire up a Boarduino without any soldering or breadboard. Then I remembered the terminal blocks I used for MidiSense!
Terminal screw-blocks allow lightweight ultra-quick prototyping: just tighten the little screws to add or remove components! Use Phoenix brand 0.1″ terminal blocks, part 1725672 (4-position), 1725698 (6-position), 1725711 (8-position), 1725724 (9-position)
Here’s an example I soldered up. You cant use huge wires, but for most small projects with 20-ish gauge wire it should be just fine!
Here is a ‘standalone’ light sensor (CdS cell, pullup resistor to Analog In 0, VRef tied to 5V)
One of the reasons I designed my own Arduino clone is so that people who wanted to design wearable or portable (ie small/lightweight) projects would have a nice and slender alternative. jordi’s original helicopter used an Arduino Diecimilla, but for weight reasons he decided to go with a Boarduino for rev 2, but even that didn’t get away without a lot of hacking….
Here is a nice-n-easy x0xb0x demo video with good sound (yay), thanks to Booster69
It’s to celebrate that I’ve finally gotten off my ass and am finishing off run #7 after a vacation-y november and retail-rushed december
Magician13134 got an Arduino starter pack and has been going all out with hacking! He designed this Arduino 3-axis tilt-mouse using an accelerometer breakout from Parallax (now available from Radio Shack) and some windows programming skills. Then he etched his own PCB, doing the layout in MSPAINT! How hardcore is THAT?
