Lots of people use solar power to supplement things like lighting power but why stop there? DIYPV has built a solar system on top of his pool pump to allow him to run the pool filter pump all day long for free. He currently has four 120 watt panels running a Hayward Ecostar pump.
 Brian Neltner sent in some information about this Sound controlled RGB LED project that he designed. He has a Kickstarter running right now to try to build a 10X10 grid of them for Burning Man. Brian provides the full schematic for those who would like to build their own. “The goal of the SaikoLED Audio Responsive LED Module is to provide a fully autonomous device capable of collecting audio
 Dustin Evans used an old NES console, a Arduino Mega, a BlueSMiRF and some LEDs to allow him to play some old school emulated NES games on his cell phone in style. When turned on the BlueSMiRF searches for a device to connect to, once successfully paired to your phone you are now ready to take a journey back in time and start playing your favorite mario adventure.Â
If you need to measure household AC voltage with your grounded scope this Differential Probe Project might work well for you.
Like so many people these days David Prutchi has a space communications array in his back yard. His modification of his FTA dish allows it to be used to receive Ku-band transmissions from geosynchronous FTA satellites as known-Az/El beacons. “The Fortec Star 120 dish is small enough to be handled by a Yaesu G5500Â Az/El rotor, yet provides 21.7dB gain in the L-band, and 27.7 dB gain in the S-band.Â
George Graves built this Constant Current Dummy Load Project based on this blog post over at the EEVBlog. It was built from a single sided board which was designed using ExpressPCB. That software is very nice to draft something up fast and it allows for an easy screen grab to etch what you see quickly. Thanks for sending this in Jim. “The only change I really made was running
Jacques Sperwer from Jacques Productions in the Netherlands shows us how he is building his Heavylift Hexacopter. Have a look at the video footage of the windmill below to get an idea of what these copters can do. This build is using a Wookong control system which looks to have all the bells and whistles. “Wookong Multi-Rotor stabilization controller is a complete flight system for all multi-rotor platforms
