Thanks to everyone at Dangerous Prototypes for organizing the competition!
I hope this time prize coupons will not be powerful enough to empty the free pcb drawer.

I haven’t seen any notification mail yet… :-?
Spambox!
I sent it out, but as a large bcc. Maybe it wasn’t delivered. Will do a post and try again if you don’t see it in a few hours.
I’ve been checking my spam mailbox regularly during the weekend with nothing there. But now I see that I got a mail from you an hour ago!
Maybe a blog entry about that it’s been sent might be good since it might have ended up on the spam filter for the others as well.
Сongratulations and many thanks to competition organizers and to all winners!
is there any more competitions related to electronics ?
Congratulations to all the winners of the 7400 competition. Even those that did not make it through, I’m sure you learnt alot. Keep at it!

I received a coupon code and ordered the Megaminis. I received a confirmation message also.
However the next day received a mail from Lynn, saying that “Your quick trigger finger beat the store and database checks. I’m sorry, the MegaMinis from JK Devices was already sold out.. Here is another coupon code:…..”
I tried today to order the only item left in the store, and got another message that the coupon code is expired!
