There's nothing worse than when you come up with a brilliant idea while you're busy with other things and then promptly forget it. Whether it's the perfect ending for your novel or a comeback you should've said during that argument with your roommate last week, it's always annoying.
The Watch Out! mini synthesizer is here to help... if you compose electronic music, that is. It's a solar powered, two-button synthesizer that you can wear on your wrist to make sure you can record that beat that's been stuck in your head all day, no matter where you are.
The synthesizer consists of an ATtiny13, a piezo speaker, a tiny solar panel, two buttons, and a mini jack all inside a 3D-printed case.
The solar panel actually determines the sound. "Dependent on the light intensity, a solar panel reads this program and gives the power for the sound production. The more light shines on the cell, the higher and louder the pitch."
The team behind it says they want to eventually develop an iPod GUI that would let you tweak the sound, and they also plan on adding a mechanical part to change the pitch.
Check out the video to see it in action.
You can find a parts list and the source code over on Thingiverse, and be sure to check the team's Wiki for the latest updates as the project moves forward.
