Yep, I finally had a project where I needed a cheap OSX-compatible analog input (gonna build a temp & humidity monitor using LM35CAZ and Ohmic SC-600), and finally had the forehead-slapping moment of

I don’t need an ADC per se; I need a board with ADCs on it.

Yep, for example an Arduino. So I’ve got one, $34, working already. One trick on OSX that tripped me up – you have to open the Arduino.app/Contents/Info.plist file and set the java version from 1.4+ to 1.5 – OSX bug. Otherwise you get RXTX errors, which are a red herring. Here it is, blink code and all:

Nice board. I got mine from Sparkfun, and it was here in a few days. Should be easy to hack on, there sure is a lotta chatter around this board. I suspect that the Arduino, just like my beloved mechanical watches, are fun because they’re hackable and comprehensible, two things that modern computers are increasingly lacking.
