Free PCB Sunday: USB RGB color changer


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. Ian did this project at DIY Life, a Weblogs, Inc. site that shut down about a year ago. Someone made some minor modifications to the design and had a bunch of boards produced, we ended up with a pile of the extras. This PCB is as-of-yet untested, you can discuss it in the forum.

We’re giving away two PCBs this week, just ask for one in the comments. Be sure to use a real e-mail in the address field so we can contact you for shipping info. Some rules after the break.

Some rules we might adhere to:

  • Yes, we’ll mail it anywhere in the world!
  • Limit one PCB per address per month
  • We reserve the right to ignore any request
  • We’re not responsible for the PCB actually arriving in the mail, no postal insurance or replacement option is available
  • Like everything else on this site, this PCB is offered without warranty

  1. I’d like one of these! Just got done designing my own, but that’s on RadioShack protoboard lol.

  2. Hi Ian…

    I am very interested in one of these PCBs…
    Nice Design, Good Work !!

    Could you send me one ??

  3. There were only had two to give away this week, thought I actually send them to the first three commenters. We’ll give away different circuit boards every Sunday, we’ll give away more of this one in a few weeks.
