How to ‘piggyback’ driver chips on Ladyada’s arduino motor shield

I really like the motor shield from adafruit industries. It is simple and it allows me to plug it in and start playing quickly. I usually have giant machines in my head, and the shield just wasn’t designed for those kind of motors. You aren’t going to end up running your prius off of one …

Slow motion from the 7d. 720p60 to 24p How-to

There were a few different stages of excitement that I went through after getting my Canon 7d. First I played around with all of my manual nikon lenses (using an adapter of course). Next I marveled at the settings and the live view feature. Finally I decided I wanted to go out and shoot some …
