Home Automation by Edward Cheung

"This centralized system can control almost all of the lights in my home, a few appliances, the garden irrigation, some window treatments, the Audio/Video system, the security system, and the HVAC (Heating Ventilation and Air Conditioning)."

Home Automation by Edward Cheung

"I can communicate with the central computer by using keypads throughout the house, any phone in the world (including those inside the home), any browser over the internet, and from my wrist watch. A webcam (with integral pan/tilt) allows me to see what is happening with nothing but a web browser."

I Colored The Sketch at Ronald's site and mailed it to him. Ronald used it in his website!!

Ronald Dekker's Projects

NIXIE II A Talking NIXIE Alarm Clock! This Nixie Alarm clock will wake you up with a personal wake-up message or sound. A "wav" file stored in EPROM is played using only a few counters and a DA converter.

The µSCOPE - A poormans OscilloScope

"These days this obviously can be done much simpler. The present generation of micro controllers is so powerful that such a videoscope concept can be realized almost completely in software. Recently I obtained a sample of the 12f675. On examination of the datasheet of this small 8 pins micro controller from Microchip, it appeared that the small package contained all the components of a miniature videoscope. In short the µSCOPE project was born, with as main objective the challenge of implementing such a relatively complex task in this small micro controller. The result summarized on this web page is a fully functional (memory)scope that samples the analogue input signal and subsequently displays it on a normal TV"
