Find the possibility
Start with a challenge prompt and inexpensive materials. Free tutorials help you get your bearings; your twist makes the invention yours.
Less waste. More wonder.
Your junk.
Your next genius idea.
Turn the stuff lying around your house into something that actually works. Take a build challenge, film the reveal, and dare a friend to do it better.
Curiosity required. Fancy workshop optional.
The first challenge concept
$5 of electronics. One useful invention.
Our promise to makers
Beginners belong here Small budgets, big ideas Honest attempts beat perfect edits
01 / The build loop
Make a little mess.
Make a little magic.
JunkGenius starts with a simple social challenge, not a complicated app. A mission, a handful of materials, and a reason to try something new.
Build. Test. Try again.
Give that old container or spare component a new job. If the first version flops, show what happened and change one thing.
Show the working reveal
Film a short video that shows your invention in action. Share the result, challenge a friend, and see whose version takes the idea further.
02 / Keep the ideas coming
