Did I win the contest? When will I receive my prize?

If you are a winner, we will contact you directly via email to arrange the shipment of your prize.

Free hardware application: Do I have to submit a project entry if I receive free hardware?
Yes, all free hardware recipients must submit a project entry by the contest deadline. Free hardware recipients who do not submit a project entry will become ineligible to receive free hardware in future giveaways.
Free hardware application: How many free devices are available?
250 free devices are available. One device maximum per person.
Free hardware application: How many ideas can I submit?
Each participant is allowed to submit one idea.
Free hardware application: I was notified that I was selected to receive one of free devices. When will I receive it?
We will notify you via email when free devices are shipped. If you haven't received an email yet, we haven't yet shipped it. Be aware that once you receive the initial notification, it may still be a few weeks until you receive the shipment notification.
Free hardware application: What happens if I receive free hardware and do not submit a project entry?

Participants who receive free hardware and do not submit a project may be ineligible for future giveaways unless the hardware is returned.

If you receive free hardware and become unable to submit a project, please contact us at and let us know as soon as possible. We may choose to arrange for the hardware to be shipped to another participant.

Free hardware application: What kind of idea is more likely to win free hardware?
We encourage creative ideas. For instance, pet feeders and home automation systems are very common nowadays and less creative. We also encourage realistic ideas. While solving world hunger is a great goal, it may not be realistic.
I submitted my project but it says "Awaiting moderation". Will it affect my eligibility?
As long as you submit your project before the deadline it doesn't matter when it is moderated. Just sit back and enjoy a well deserved break!
My project is locked and I can't edit it anymore. Why is that?
All projects entered in the contest are locked after the submission deadline to ensure that they remain the same during the judging process. They are then unlocked after winners are announced.
Somebody copied my entry! What can I do?
When judging entries, we take into account the submission date. When an entry is clearly plagiarized from another, we favor the original entry. If you believe the result of the judging is unfair, please email us at to appeal.
