The Digidash project is an open source digital dashboard designed just for the megasquirt EFI system we mentioned in our diy EFI motorcycle post. Unfortunately, the site doesn’t link the hardware design. From the description, I’m assuming that it’s essentially a graphic LCD driven by an Atmel microcontroller that talks to the Megasquirt to get the display info.

XY Fabric Interface
[Maurin Donneaud], the giant fabric keyboard builder, has also been working on the XYinteraction tactile interface. XYinteraction is made of two sheets of fabric stretched across a square frame with the conductive threads of each sheet running in opposite directions. When the user touches one of the sheets, it makes contact with the other sheet, relaying x-y coordinates to a computer via a LilyPad Arduino. More details after the break.
LED Ambient Light Strips
[Shadow] sent in his ambient LED strip project. He picked up a ton of RGB (Red/Green/Blue) LEDs off of eBay and built several LED strips. To get up and running, he used an LED-wiz controller. With the off the shelf controller, this is a pretty easy project, and the ambient lighting effect looks great. Check out the video after the break or on the project page.
In 2006, we posted about [rafkep]’s similar ambient lighting project.
Solar Powered Lawnmower
Our post about what it takes to convert your home to solar power probably put you in a green mood, but if you want to start with something smaller, check out this guide on how to add a solar panel to your lawnmower.
You will need a battery-powered lawnmower for this, as well as a 12-volt solar charger with a car lighter jack. This easy hack mainly involves a small amount of work with the wiring; the car lighter jack must be removed from the solar panel so that the wires can be attached to the batteries. Yeah, that’s it. We’d love to see a more elegant solution since the way it is now you have switch the wiring from parallel to series everytime you want to mow.

Mpguino: Injector Level Fuel Montoring
[dcb] posted about his work on the mpgduino mpguino. The project uses an arduino with a LCD display to monitor fuel consumption based on vehicle speed and the pulses of the fuel injectors being fired. It’s definitely an interesting project given current fuel costs and the passive nature of the project. You can easily tap the wires needed for the monitor and remove it without voiding your warranty (not that we really care).
Giant Fabric Keyboard
[ladyada] pointed us in the direction of this giant fabric keyboard built by [Maurin Donneaud]. The construction of it looks fairly simple, like the buttons used in [fbz]’s WiFi detecting backpack strap, but on a larger scale. We’ll take you through its construction, pictures and all, after the break.
Beverage Cooling Contraption Contest
Let’s face it: no one likes warm beer. In the arid August air of Las Vegas, though, it’s difficult to get anything else. To combat this problem, Deviant has hosted a competition the last three years at Defcon called the Beverage Cooling Contraption Contest, or BCCC. We’re not talking about something as simple as a Coleman cooler or even a peltier cooler: the devices entered in this contest have to be able to take a beer from hot to cool and your glass within minutes.
