Small Electronic Logic Blocks - eBlocks
eBlocks writes "eBlocks are small low-cost electronic devices that can be easily interconnected for a wide variety of applications such as: detecting motion, light, water, sound or magnetic fields; triggering a buzzer, a light, an electronic relay or a lock. Devices can communicate wirelessly or can be controlled remotely via the internet or a telephone. The eBlocks technology has been developed by a professor at U.C. Riverside who is looking for inspiration on its best uses. Try out the simulator. Suggestions and comments welcome!"
