Reverse Engineer a Power Supply to find Fault

Repairing most electronics these days is pointless unless you are doing it for fun. Take an answering machine for example. You can purchase a new one for $10 but to find a fault in a dead one you could spend days of your spare time.

CNC Milled LED Backlit Sign Build

The Department of Homeland Security has something they call the Threat Advisories, these come in 5 levels.

DIY Big Screen needed for the Kinect

Inside the Parrot AR.Drone

iFixit has taken apart one of the coolest toys I have ever seen. The Parrot AR.Drone you can see by the electronics inside that this is no ordinary toy. I am thinking that the guts of this system could be used to fly the SkyFly. Nice thing about the AR Drone is that it is made to be used, broken and repaired. This is one piece of gear that will

DIY Circuit Board UV Exposure Box with Timer

Triuky left a comment about his DIY Circuit Board UV Exposure Box with Timer in the comment section of this DIY UV LED Double Sided PCB Exposure Box he us using some small UV florescent tubes similar to the ones that I used when making my UV PCB exposure system.
