Arduino based EATC replacement

The Electronic Automatic Temperature Control Module on [Dan Mattox’s] 2000 Ford Taurus bit the dust. The junkyards in the area didn’t have a matching replacement and a new one is pretty hard to come by so he built an EATC  replacement from an Arduino Mega. It includes a solenoid controller board for the vent selector, blower control, and new switches to control the power windows. He’s got the system up and running which is important because after removing the broken EATC the car was stuck blowing 90-degree air at full blast. He’s put together a demo and an installation video which we’ve embedded after the break but there’s also a photo album you can page through. The sketch that we developed to control the system is up at pastebin so get it while it’s hot.

Arduino-human synthesizer

(Thanks to [Aaron] for the tip) As a promo for [Calvin Harris], some of the creative minds at Sony Music have put together an Arduino-based sythesizer composed of 15 bikini clad babes. By analyzing which circuits are closed, the Arduino Mega is able to tell a sequencer which sample to play. The only innovation happens to be that the circuits are painted onto the aforementioned girls with a conductive body paint known as Bare.

Developed by students at the Royal College of Art, the paint is not available for purchase, but they are willing to mix a batch up for art installations or performances. Technical stats (such as resistance) have not been released, but for a washable paint it seems to be performing quite well.

How was the whole project set up? The video below reveals all:

Evil Mad Scientist Laboratories spotted one of the first images of the Arduino MEGA. The board is based on the ATmega1280 microcontroller, which has 128KB of flash,4KB of RAM, and 4KB of EEPROM. We haven’t seen any official specs yet, but the silkscreen shows 12 PWM connections, 36 Digital I/O, and 16 analog inputs. The post mentions 4 hardware UARTs and an I2C bus as well. No release date yet, but we can assume it’s soon since the hardware was already demoed at ETech.
