Daniel writes – “You know all those RGB LED projects with microcontrollers and power transistors and stuff? Well, this is the almost-too-easy version. Modern two-pin RGB LEDs are cheap and pretty, and they don’t need so much as a current limiting resistor, if the input voltage is right. Just hook ’em up to about three […]
A MAKE reader sent in a video of this interesting looking 3D modelling program (called InDex by Digital ArtForms) that lets you sculpt with your hands, anyone ever try it? – Link & more.

As well as some priliminary results between “Star & Delta” 3-phase configurations of the stator.” – Link. Related: Bent Genny (Human powered […]
MAKE Flickr photo pool member Mr_tentacle has a new bot! “The overall height is about 15”. Changes from the original design include more height (4 more inches), Hitec H5995-TG high torque servos for drive instead of the original gearmotors, 6″ diameter wheels, and more mass at the base to reduce the torque load on the […]

Gareth writes – “I posted another how-to on Street Tech related to my MAKE BEAM articles. This one is on Vibrobots, a type of solar-powered bot that gets around by using pager (or other DC) motors that have vibration weights on their shafts. The control circuit is the same one I talk about in my […]
