If you have ever wondered how one of those RGB LED light bulbs work have a look at the article that chr has put together. By monitoring the IR LED of the remote he was able to snif the IR remote codes for the functions. Once he knew the IR codes he used an Arduino to run through all of the byte sequences but unfortunately there were no easter
Julian Ilett demonstrates his Arduino Solar Charge Controller. He has mounted all of his Arduino modules to a piece of wood to keep everything nice and neat. “High efficiency values (96% – 97%) are achievable when the buck converter is stepping down from 18v to 12v. With a 72-cell panel and the converter stepping 35v down to 12v, the efficiency drops to around 88%.”
Do you have a boat and are looking for the next toy? I think this Flying hovercraft might be high on the list, just imagine not needing to drive your trailer down the dock to unload your craft, just drive it down the ramp. If there is some pesky land and trees in the way from one water way to the next just launch and fly over. If these
If you want to fly an RC plane but don’t think getting used to flying with a standard RC remote this glove control system might be a build that could help you fly. It has some interesting features that help to make flying the plane more intuitive such as simply tilting your hand from side to side to bank the plane instead of moving a joystick. “The Spatial Hand
If you like working with foam you can easily carve up a large block of foam with a carving knife but that isn’t very accurate and will make a huge mess. The cuts won’t be very smooth and it will take a long time to make something look good. The solution is a hot wire technique, a hot wire will cut through the foam like butter allowing the user
If you want to make your next robot be able to use hands like a human the Open Hand project would give you a head start in this direction. Building a cheap model of the complex human hand is no small task but if this campaign is successful I think we will be heading in the right direction. Via: Make “The Dextrus hand works much like a human hand.
Adding some movement to your next Halloween project doesn’t need to be complicated. Have a look at the Graveyard Creep Prop that Eerie Acres Cemetery put together. It is a simple motor that moves a pivoting shaft back and forth as it rotates. The effect is not complex but for a prop that will be seen for a few seconds by your guests it is sure to look great
