 Bogdan Raducanu from Electro Bob has installed some LED Lighting that uses PIR Sensors in his kitchen and bathroom, the LED strips provide sufficient light for the areas and only turn on when someone id in the area because of the motion sensors that have been placed in strategic locations. He has documented his steps so you can also have some automatic lighting in your house. “Tiny PIR
Who knew pacemakers were so versatile, I thought they only had one purpose. This Pacemaker Camera Flash Project sure proved me wrong. 🙂 David Prutchi sent in his latest project where he has used an old pacemaker as a millisecond timer for high-speed photography. I guess after 20 years designing medical electronic instrumentation and developing 70 patents your electronics junk box has a bunch of medical devices that are
An automatic stair lighting system is one which lights each step LED when a user starts to climb or descend.  Erica Kane has developed a similar Open Source DIY Automated LED Stair Lighting system using an Arduino Pro Mini, a M5451 LED Display Driver to power the LEDs and a PING ultrasound distance sensors to detect when someone enters the stairwell. The Eagle schematic file is here and the Arduino Processing
