I put my second product up on tindie.com as a fundraiser. It’s a breakout board for one can use to make custom Analog style gauges. The actual drive is a stepper motor – the same model used in GM cars and trucks. The breakout uses an arduino library written by Guy Carpenter, who has a great blog over at http://guy.carpenter.id.au/gaugette/
So far things have been going great, I was able to make my funding goal in less than 24 hours! Needless to say I’m very happy. I’m sure the US Postal Service is going to love me too when I start shipping out the gauges ;-).
