POV Hard Drive Clock

  This Hard Drive Clock is fantastic, especially the great looking painted front of the clock. It really looks like a piece of art. As you probably know we love hard drive clocks around here and almost any projects that can be made with used hard drives! Thanks for the tip Maciek.

Carbon Fiber Foldable Bike

  I think small electric powered devices such as this one will become very popular in the next 10 years. Who needs to drive a 2 ton car if you are only transporting yourself a few blocks away to catch a movie or go for lunch?

Starting Lights using 555 Timers

  Who says that everything needs to be done using microcontrollers?

printf and scanf examples for Microcontrollers

"Programming in C can be a daunting task for a beginner, especially when new programming languages like Python make it so easy to accomplish basic tasks. Taking input from the user, and displaying data back to the user in a human readable format is one of those things in C that

Nixie Tube Clock Kit Build

  We have featuring tons of clocks around here lately. Nick Romano sent in a clock that he built from a kit he got from a Frank Techniek. It is spiced up with lots of cool extras that make it shine!
