OK, everyone has seen the dude who made an LED POV (persistence of vision) clock out of a hard drive, and we’re all very impressed (no, seriously). But not all of us have those skills. This is a hard drive clock that requires only a power drill and some basic hand tools. No electronics knowledge is necessary. Total project time: 60-90 minutes.

I think this one is interesting as you can actually see that it’s a hard drive. The one I made had a different goal though – to only have hard drive parts visible.
Anyway – I like’em both.

With the addition of one capacitor, one relay, and a small piece of wire we can convert an inexpensive wireless doorbell into a remotely controlled relay useful for a wide range of applications. These include remote PC starting, lighting control, Halloween effects control, or virtually anything that can be controlled by a pair of relay contacts.

And here’s some food for thought for you DIY’ers. How about taking one of those cute small radio controll cars and turn it into a dimmer control? The benefit of using these small cars as a build base would be that the rf reciever cards are very very small.

On this page i will explain how i created my own colour changing lamp with red, green and blue leds that fades between all colours of the rainbow. It really comes out well at night when other light are dimmed. In daylight conditions the colors aren’t noticed well. Although it’s low budget i must say the result is nice.
