From the MAKE Flickr pool Joining the modular forces of Arduino and Lego, Greg and Rael built the above-seen motor shield with a convenient plastic brick interface. Head over to Flickr for more project pics. In the Maker Shed: MotorShield for Arduino Kit

This might be just the thing for a robotics project cancelled on account of – “expensive”. Professor Mason created a quadrature encoder by fitting a motor with 2 inexpensive hall-effect sensors and a small magnet – In this application, two sensors are attached 90 degrees out of phase around the motor. A small permanent magnet […]

On the RepRap site, they have a short piece on hacking the Solarbotics GM3 gearmotors. The GM3’s are the standard motor used in the RepRap extruder. The piece covers locking the internal clutch to get more torque, lubricating the gears, and an easier mounting solution. These tweaks can obviously be useful in other motor applications. […]

Here’s a useful tutorial on how to harvest a motor from a waching machine, including a section on how to use bridge rectifiers to produce DC from an AC motor. Supposedly these are ideal for driving wind generators, so check out your wind exposure, make an inexpensive generator, and start charging some batteries! (via hack […]

The home-made motor is a valve-operated 12 cylinder 4 stroke engine with two low operated camshafts with oil lubrication and air cooling. The builder is hoping to eventually offer the engine as a kit. V12 RC-Engine [Via Hacked Gadgets]

If you’re showing data from digital sources, why not use a digitally-controlled analog meter? laser cut acrylic meter face & needle, tiny 25mmx12mm $3 servo, and arduino. – Servos as meters on Flickr MotorShield for Arduino Kit
