I've been working on an interesting project lately and figured I'd post up a thread to see if anyone else is working on anything cool! Here's what I've been working on... Basically I'm building my own air ride controller for my '63 Rambler using an Arduino Mega and various other hardware. I've used Arduinos a couple times in school but nothing crazy, the first code I ever actually wrote for an Arduino was the air ride code I wrote last night and after testing the components today, it appears that it should work perfectly. Why I'm doing it: The electronics, valves, and a few odds and ends cost me about $150 total and every aspect is totally customizable. For $150 you can buy half of a used accuair manifold, so you get the point. Here's a pic of the major control hardware (minus Arduino): I'm running a 4 valve, pressure based system for simplicity and because its cheaper and easier to code than an 8 valve setup. The cool thing is that even though I only have 4 buttons, I can code strange combinations of button pushes to do weird things like bounce the front or some shit. I'm probably going to mount the Arduino, relay module (for the valves), the power supply, a fuse block, and a few relays on a sheet of polished aluminum to mount in the trunk. It should look something like this: And for the switchbox, I mounted the switches in the battery area of a 1960's/70's era GE Walkie Talkie, and the battery cover snaps on over it! In case you were wondering, yes the walkie talkie still works, the battery just doesn't fit in there any more... Also the antenna is like 4 feet long when extended which I though was hilarious. I should be able to test the entire system next week when the correct relay module gets here. For some reason there are modules available that use 24VDC just for the relay coil when the rest of the board is 5VDC logic... Anyway, any suggestions and comments are welcome and lets see what else you fggts are working on!
