Free PCB Sunday: USB RGB color changer

in Free PCBs by Ian | 17 comments

We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few professionally-made PCBs from one of our past or future projects, or a related prototype.

This is a USB controlled RGB color changing light. Someone made some minor modifications to the design and had a bunch of boards produced, we ended up with a pile of the extras. We’re giving away two PCBs this week, just ask for one in the comments.

Some stuff:

  • Yes, we’ll mail it anywhere in the world!
  • Be sure to use a real e-mail in the address field so we can contact you for shipping info.
  • First come, first serve. If we can’t contact the first commenters we move down the list, so you could consider making a request even if it looks like all the PCBs are gone.
  • Limit one PCB per address per month please.
  • Like everything else on this site, PCBs are offered without warranty.

We try to stagger free PCB Sunday posts so every time zone has a chance to participate, but the best way to see the post first is to subscribe to the RSS feed.
