This video gets into exactly what I want to know: how can I turn my Arduino-based prototype into a commercial product? The video is really light on details, though. Has anyone here done this? I've got one prototype completed, and two others I'm working on. Unfortunately, I'm a programmer type, with very little knowledge of electronics, circuit design, and electronics production. Also, I just ordered a couple TI MSP430 LaunchPads to see if they're capable of doing what I've done with the Arduino, since the MSP430 looks like a much cheaper option.
