great... another project on my list
anyone want to make me one?
I can program just about anything except AVR, so I'm no help with making this specific one, but it should be adapted pretty easily to an Arduino that doesn't need a programmer. Unfortunately even an Arduino Nano would be a little bigger than the custom PCB, though you wouldn't need the counter.
So I made up one the other day using a PIC rather than an AVR and a counter. Unfortunately the only hall effect sensors I have are too small for hand wiring. It'll need to wait until my next Digikey order before I hook it up to the hall effect sensors for testing.
I didn't think all that many people were interested. I was going to make up 4 or 5 and just hand them out for $10 or something. If you really want something DIY I could design up something around an MSP430 which has a cheap programmer and just makeup the PCB's and you can order the parts and solder it up yourself, but it's going to be all through hole and the board will be bigger.
