This guitar looks quite good with some blue LEDs installed. I think a great next mod for this guitar would be to make the LEDs flash in time with the music. "Stuff used: - Acrylic Guitar

Andy from Trademark Laser let us know about this Piezo Drum Kit a while ago. Alex sent in some pictures of his finished product. It looks great but that’s how it goes when you have a laser cutting business.

Bob Davis has cranked up the power on his can crusher. By adding a defibrillator capacitor his Can Crusher is now supercharged! He has also provided the schematic of the design on his site. "I purchased a defibrillator capacitor on EBay and have upgraded the old 2.4 KV can crusher to a 5 KV can crusher. I added a voltage doubler on the output of the Microwave Oven Transformer (MOT) to get almost 5 KV. The defibrillator capacitor is rated at 30 uF at about 5 or 6 KV." |

Ryan from Ohararp has put together a modular Wireless LED Scrolling Display that looks very flexible and uses that cool ioBridge that we are starting to see used more and more. "A uPic is used to talk to the led drivers (8xMax7219′s) through the serial port (in this case an XBEE)."

As homes get bigger it’s harder to balance the heating system. You can close and open vents all you want but all it takes is a few closed doors to throw off the entire system. Jason Clark from Cyborgworkshop has overcome this issue by designing an Arduino controller that monitors sensors in all areas of his house. Servo motors then control dampers which put air where it’s needed. Have a look at the build log of the Whole Home Information Awareness project for some climate control inspiration. "At a high level, temperature and humidity sensors in each room of the house instruct a micro controller to open and close the vents in a specific way to balance out every room in the house. The end goal is that no room will be more then 1.5 degrees and 5% relative humidity different from any other room. No more hot guest bed room and cold living room. To safely pull this off I’ll need temperature and humidity sensors in the return vents of each room, servo motors connected to the main damper controls for each vent, an air flow and pressure sensor in the HVAC main line to keep the motor from getting burned out, an Arduino to gather all of that sensor data together and a Linux box to process the data, control the sensors and create graphs of what’s going on."

This Led Matrix Dice made by Itay Donenhirsch looks very cool. Give it a shake to roll a new number. "The cube is driven by three 1.5V small button cells (which are sold here as batteries for EasyPark computerized parking ticket). The brain of this gadget is a ATmega168. The ATmega168 is programmed using avr-gcc and avr-libc. The MCU is connected to the matrices using a ULN2008 as a current sink and a 74LS164 as led driver. For extra fun I pulled a speaker from a Nokia mobile phone and connected it as well."
