This week we’re giving away free PCBs for an upcoming project, an AVR ATtiny13A-based holiday ornament and card. Later this week it’ll be available at Seeed Studio assembled, and as a kit, both under $20 (shipped). The how-to article should be out on Tuesday or Thursday.
We received and tested these PCBs in the last 24hours. We were expecting regular green PCBs, but got black, which isn’t a very traditional Christmas color… Would you prefer red, green, black, or another color on the final kit?
There’s some urgency with this project – to deliver anywhere close to the Holidays we have to order a number of these up-front, instead of doing a preorder. That’s a bit daunting. If you have a suggestion for quantity, or would just like to buy one, please let us know so we can get a handle on how many to order.
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. Sometimes we have extra PCBs or we can’t contact a commenter. When this happens, we move to the next commenter.
- Limit one PCB per address per month.
- Like everything else on this site, PCBs are offered without warranty.
We try to stagger the free PCB Sunday posts so every time zone has a chance to participate, but the best way to see the post first is to use the RSS feed.

I will take one.
I’d like one also please.
Ah, so this is the AVR project you mentioned some time ago ;-)
that one looks fine and shall be e nice gift for my mother :-)
i prefer red colour pcbs with yellow and green leds but also any other colour… – is there a piezo on the back to hear some christmas songs? ;-)
I like the red PCB’s. I see way to much of the green ones.
Pick me, pick me. I like one to!
Actually, I kinda like black, it’s holiday-neutral. (Halloween Tree, anyone?)
You might want to drop the year from the final version, though.
(PS: Me too, please!)
@mike – Since we’re up against the wire, I did just that! lol!
