[Josh] got rid of the standard, factory gauges on his GSXR Super-bike and installed a custom built instrument panel which displays some additional parameters which the regular instrumentation cluster did not. He was working on converting his bike in to a Streetfighter – a stripped down, aggressive, mean machine. The staid looking gauges had to go, besides several other mods to give his bike the right look.
Luckily, he had the right skills and tools available to make sure this DIY hack lives up to the Streetfighter cred of his bike. The important parameter for him was to log the Air / Fuel mixture ratio so he could work on the carburation. Along the way, he seems to have gone a bit overboard with this build, but the end result is quite nice. The build centers around a Planar 160×80 EL graphic display lying in his parts bin. The display didn’t have a controller, so he used the Epson S1D13700 graphic controller to interface it with the microcontroller. An Atmel ATmega128L runs the system, and [Josh] wrote all of his code in “C”.

[astralpancakes] wireless arcade stick project looks like a great place to start if you want a simple project. Well constructed arcade sticks can cost $100+, but with all the MAME cabinet builders, the parts have become easy to acquire. The stick has a rigid wooden case with a metal faceplate. All of the component connections are soldered to the pads of a Logitech wireless controller. [astralpancakes] built this specifically to play Street Fighter III: 3rd Strike.
The Universal PCB project lets you make any controller (specifically arcade sticks) console agnostic. A PIC microcontroller is used to translate between the button presses and the signals for the specific console you’re connected to. It uses a DB15 for the external plug. The PIC knows which console you’re plugged into based on which pins are high or low in your console specific adapter cable. The board includes a piggyback plug so you can plug in an Xbox360 controller board (like the one above) since the console requires authentication. The PIC’s firmware is conveniently upgradeable over the USB cable.
