I thought it would be cool to have a clock that looks like an old Simpson 260 multimeter. The clock consists of three multimeters, the first meter displays hours, the second displays minutes and the last displays seconds. A 16F628A PIC microcontroller keeps track of time and

Youtube user vegmatic1966 has made lots of electronic experimentation videos. The two videos above explain a simple AM Transmitter that uses a 555 Timer and the video below shows off a AM Transmitter that uses a PICAXE microcontroller.
Adam Greig from Negative Acknowledge has developed a nice Nerf Sentry Gun, he used the NERF Vulcan which was the same gun I was thinking of using for my Nerf Gun project which is currently being finished but it was quite a bit more than the knock off that I ended up using. Via: Hack a Day “The gun itself is now running off a 3-cell lipo pack, which about
