Every Tuesday we give away two coupons for the free PCB drawer via Twitter. This post was announced on Twitter, and in 24 hours we’ll send coupon codes to two random retweeters.
Don’t forget there’s free PCBs three times a every week:
- Hate Twitter and Facebook? Free PCB Sunday is the classic PCB giveaway. Catch it every Sunday, right here on the blog
- Tweet-a-PCB Tuesday. Follow us and get boards in 144 characters or less
- Facebook PCB Friday. Free PCBs will be your friend for the weekend

Some stuff:
- Yes, we’ll mail it anywhere in the world!
- Check out how we mail PCBs worldwide video.
- We’ll contact you via Twitter with a coupon code for the PCB drawer.
- 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 posts so every time zone has a chance to participate, but the best way to see it first is to subscribe to the RSS feed, follow us on Twitter, or like us on Facebook.

So how exactly does this work? You have to win the lottery to get your free PCB and then when you are done and blog/post it you get a new one? Is there any other way to get the “chain” started? And how would you get a pcb woth two codes? Do you need to win twice in order to get started?
Is there some way to donate money for the “free” codes?
Ways to get coupon code:
Sunday bu blog comments
Tuesday by Twitter
Friday by Facebook
And the 4’th way is simply asking for a code.If you’ve been trying code from weeks but don’t get one, and you’re so serious about making one project that you have all the parts lying around, then just contact Ian, he might give you free code.
If you need a PCB which costs two codes, and you have one code worth coupon, just ask for the value to be raised.
You can only buy Buspirate DIY SOIC edition PCB with money. DangerousPrototypes doesn’t even accept donations. You can support DangerousPrototypes by buying from SeeedStudio or by becoming active person in the projects in development.
