Following the exciting An Unconventional Clock contest, a new Beginner contest has been announced on /r/diyelectronics:

Making Music

Make something with electronics that makes music!

The rules include these constraints:

• Sound must come from the project itself
• Do not amplify or change sound from another device
• No music signal can be used as input to be processed
• Human input like knobs or buttons is OK

One winner will be decided by community vote, and one by the judge. Each winner will be awarded a $30 gift code for OSH Park.
