This Space Invaders game does more with less. [Rjk79] managed to make a video game using a two-line character display. The game consists of a wave of invaders on the top line, with the defender cannon on the bottom. The invader isn’t just stationary, but randomly moves to the left and the right. The image above captured a little … Read the rest
This glove controller let you play a musical game. The challenge is to perform the correct wrist motions at the right tempo to play the intro to the song Where is my Mind by the Pixies. This is demonstrated in the video clip after the break.
We often see flex sensors used on the fingers of glove projects, but … Read the rest

Piezo speakers require a small crystal with piezoelectric properties, so this build is the perfect followup to [Steven]‘s tutorial for … Read the rest

The example he shows in the video (embedded after the break) catches the television power signal from a remote, then sends it again after about thirty seconds. This shuts off … Read the rest

Clap On!… Clap Off!… was super awesome when The Clapper came out in the mid-eighties. Now [Mathieu Stephan] is trying to make the concept much more functional. He put together a controller that lets you knoch on walls to control things around the house. It’s called the Toktoktok project and uses small boxes to receive user input and control … Read the rest
