Water Detector
History
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.

Very High Gain Microphone
History
This project is my father’s idea, he found in an old army surplus store with a radar dish and mount. His idea was to make a very high gain microphone to be able to listen to almost anything, like birds or whatever else you want.

This project is one of many I have undertaken to control my house using a set of rules, a web interface, a logger and many more components. This project is a light dimmer which has multiple control interfaces such an RS485 network, an infrared remote control, a proximity touch slider or touch sensor.

LED Sign with MMC Memory card
History
At the beginning this project was to buy a led sign to interface with my home automation network. This automation network display information like temperature, wind speed, humidity, etc. I had bought on EBay a LED Sign but when I received it I got a surprise! There was no serial port to program messages… After a couple of days, I look inside to see how it was built.
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.

Bar Code Reader
History
This is a low cost bar code reader made from a product which has a very long history. You can see it at this link. The bar code reader named CueCat is built to be connected in a PS2 keyboard port (standard PC/AT Keyboard). The problem is the information encrypted.
