The deadline for challenge #2 of the Hackaday Prize is next Monday, July 19th:

Enter one or more of this year’s challenges for the chance to win cash prizes and move on to the finals, where our panel of judges will decide on the grand prize winner! With $25,000 on the line, and numerous other opportunities to win, there’s no reason not to enter!
Ultimately though, the Hackaday Prize isn’t about winning money. It’s about creating impactful change through the kind of hardware innovation only our amazing community can provide.
