Over at Mad Lab Industries, they had the idea of building a quadcopter that could walk and fly. By combining a hexapod with a hexacopter, they ended up with this creation.
The hexapod part started off with PhantomX Hexapod Kit, but it was far too heavy to fly. To reduce weight, they manufactured carbon fibre parts for the frame and legs. Even with the weight reductions, they still needed to six rotors to keep it stable.
The hexacopter part of the build uses more custom carbon fibre parts to mount the motors. The booms and mounts are also custom built out of aluminium. They used six E-Flite motors, propellers, and ESCs to provide lift.
A variety of controllers are used to run the robot. Two Arbotix devices handle the hexapod control, and a Hoverfly flight controller keeps it in the air. It’s controlled remotely using a Spektrum controller.
They have some ambitious next steps, including a mechanism that disconnects and reconnects the hexacopter and the base. After the break, check out a video of this impressive build in action.

The etsy of electronics project, Tindie, has a brand new feature: It’s a Kickstarter-esque endeavor called a Fundraiser that allows you to sell your projects to other electron enthusiasts.
Of course the new Tindie Fundraisers may soon be just another Kickstarter clone for “exciting,” “new,” and “innovative” Arduino dev boards, something we’ve lamented before. We’re really interested in seeing Tindie used as a platform for group buys; a solution to a maker’s special hell where buying one component costs $100, but ten cost $200.
Already there are a few really cool projects up on the Tindie Fundraisers including a breadboardable Parallax Propeller dev board. Yes, someone finally made one that doesn’t cost an arm and a leg.
In addition to the new Fundraisers, [emile] also closed on $500k of seed funding for Tindie. It’s wonderful news for something that is sorely needed by the maker community. Tindie is also hiring, so if you’re a Django/Python wizard go drop everyone’s second favorite robotic dog a line.
Here’s another hack that we would definitely discourage you from trying at home, 244 9 volt batteries wired in series. There’s really not much more to it than that, but [jersagfast] takes this setup through its paces arcing through air first, a LED light second, and then a CD. The air arc is probably the most impressive, but a CD doesn’t look happy after this kind of abuse either. Around 4:38, a capacitor is abused for yet more arcing.
In theory, 244 9 volt batteries in series should be nearly 2200 volts, but as measured (in sections), it “only” came out to a “measly” 2000 volts. Still plenty of voltage to be harmful or even deadly depending on the current emitted. Passing on this hack at home is strongly encouraged. On the other hand, you should watch the video after the break to see what happens. Much safer. Arcing starts around 1:44!
