Fresh hacks every day
We haven’t heard much about 3D printing using stainless steel as the medium, but that’s exactly what’s going on with the lugs used to assemble this bicycle frame. They’re manufactured using LaserCusing, which is a brand name for parts produced using Selective Laser Melting. The video after the break gives you an overview of what it takes … Read the rest
It’s difficult to contain our excitement for this tiny quadcopter project called the Picopter. [Frank] managed to pull together an impressive collection of features when developing the project. First off, the quadcopter itself uses all-PCB construction. Even the supports for the motors are PCBs with keyed slots to mate perpendicular to the main control board, then held firm with … Read the rest
[Alex] built an add-on board for his TI launchpad that lets him use it as a wireless controller for an RGB lamp (translated). As you can see above, the board has a pair of female pin-headers which make it easy to install or remove the board. This way you can use it for other projects without any hassle.… Read the rest
[Lars] shows you how to get a perfect score on the first four levels of BIT.TRIP RUNNER by using an Arduino to time and send button presses. This is a pretty simple game that uses a couple of buttons to jump or slide past obstacles. The constant speed of the character makes it quite easy to time these movements … Read the rest
Here’s one way to get more control of your camera lenses. [Vladimir] built an Arduino-based pass-through ring (translated) which intercepts automatic lens controls. It’s meant for use with the Canon EOS lenses which have their own electronics allowing control of things like focus and zoom.
It seems like part of the motivation here was to uses the lenses … Read the rest
[Valentin] used a simple concept to build this auto-reversing rotating platform. The concept is extremely simple, the leads for the motor are attached to a double-pole double-throw switch which allow the polarity to be reversed. Flip the switch in one direction and it spins clockwise. Flip it in the other direction and it spins counter-clockwise.
In this case, he’s … Read the rest
Straight from the Aerospace Controls Laboratory comes a variable-pitch quadrocopter designed by [Mark Cutler] and [Jonathan P. Howe]. While real, full-sized helicopters always have variable pitch rotors, changing the pitch of the blades on remote control aircraft is a fairly uncommon modification. When it’s done right, though, being able to easily change the thrust direction of a propeller leads to … Read the rest
