You have seen propeller clocks before, but what about a Nixie Propeller Clock? I didn’t think so! Check out the link for code and a schematic. “I stuffed the board with the PIC, the crystal oscillator, two logic chips, 10 HV transistors, the nixie, the HV inverter from a disposable camera flash circuit, the 7805 5V regulator, a 0.6 Farad memory cap, diodes, and the pushbuttons for setting the time.
Got a RC chopper, why not take a camera into the sky for some aerial pictures? “Here’s a 3.4 I picked today.

While gestating the idea my first thought was to have roomba follow a line to the fridge and back. And a
If you need to set a quite door bell period this is a cool (high tech) solution. Code and a detailed circuit explanation can be found at Richard Cappels site. “To set the timer, you just push the button momentarily, and when its released, the amber LED will come on and the doorbell circuit is disabled (the door bell button doesn’t work) for a 10 hour period. At the end
