If you have one of those electronic fly swatters kicking around you might want to hack it into a cool looking light. Steven from RimStar has just completed his Fly Swatter Compact Fluorescent Light Hack. The fly swatter is powered from 3 volts (2 AA batteries). The circuit produces a high voltage that electrifies a grid which the fly will short out through his body. The grid is removed
Ben Heck shows us how you can be a one man video recording machine. Don’t you hate it when you need to reposition the camera for multiple shots. Using a PIXY he was able to make a system that will look for a certain color and then reposition the camera for the perfect shot. Ben makes good use out of his 3D printer to make many of the parts
 If you make your own PCBs this TwinTeeth machine might be just the thing you need for your bench.  Thanks for the tip Charlie & Victor “It includes the following functions: UV Laser photoengraving on sensitive film or presensitized boards using an ultraviolet laser. Drilling vias and holes using any mini-rotary tool like Dremel® or Proxxon®. Dispensing solder paste with precision on SMD PCB pads. Plotting circuits with
Product testing is very important, you can run a battery of electrical testing on your PCB but a visual inspection is also very important to spot failures that are waiting to happen in the future. Our friend Bob Davis has been busy repairing all sorts of random electronic items. The Bad solder joints seen above are from a Crown XTi 1000 power amplifier which is an amp that retails
Dragao has a Sonic Cartridge that had some invalid instructions that would cause the game to crash at a certain point. The solution wasn’t to find a replacement game at the local flea market, he Resurrected the Sega Cartridges using some old Computer Chips. The game was originally loaded on 16 bit memory chips, not having any of these handy from the donor computer motherboards he piggy backed 2Â
Bob Johnson completed his DIY Water Level Sensor project. It can sense 4 levels of water, the results are transmitted using some Xbee devices. “The distance from my barn to the house is over 700ft. I used a 2.4Ghz yagi to send the signal to the house. This works great and no outside antenna is required at the receiving end. I have tried this setup at much smaller distances, and
When your RC plane flies out of transmitter range some of them are setup to start a slow bank so that it hopefully flies closer to you and you can reacquire communication. What if that fails and the plane comes crashing back to earth? This Lost Signal RC Alarm & Lost Plane Finder project will help you in this case. When your transmitter is not connected the buzzer will
