    This is a very simple one.  That's the only project who don't have any MCU, why??? Because it is connected to a external MCU!,  It is a water detector who serve to close the main water valve of my home if water is detected at certain places.

Mood Lamp


History

    After I made my Kitchen Mood Light,  I had another idea for 3W RGB LED's.  My idea was to make a simple lamp with 3W RGB LED's, controlled by a MCU, and have an IR remote control to change the color, effects and patterns.

Propeller Clock

History

I got this idea by browsing the web. I found by hazard  Mr. Bob Blick's page who make the first propeller clock.  I began to check how can I build one myself.  Base on AVR AT90S2313 I saw rapidly that my MCU must be clocked very fast to make all the calculations needed to light the leds at the right place.  The speed is at 16Mhz,  4 times faster than Atmel's specifications. It's working without any problems.
