Balloon Controller PCB Preview
So, last night we made the totally irrational and silly (and awesome) snap decision to make a homebrew PCB for this controller. I spend quite a while laying it out, minimizing traces on the top to connections we can make with wire if we don’t see dual layer homebrew working out. I completed the first revision, and printed it out to scale on some paper, then using my poor abused knife I started carving out holes and wedging components in the paper. This allowed me to see some minor layout problems (sensors overhanging things, caps too close together) and get an idea of what the completed board would look like. I did not put all the components in, just the big ones to see how they’d fare.
Honestly, I’m shocked at how few problems I saw with the layout. The image I used for testing is just the pads and silk screens for all the components, no traces or vias or anything like that. I’ve snapped a quick photo with my Droid for you all to look at, it’s below.
