4pcb: Test Hops - 8/26/11

4pcb is a miniature quadrotor built on a single printed circuit board. (The board is its structure and its electronics.) It weighs 125 grams and is powered by four brushless motors. The processor is an Arduino Mini. It's radio controlled and has a 6-degree-of-freedom inertial sensor for stabilization. The control loop still needs some tuning, and yes it could also use some landing gear. More info: http://scolton.blogspot.com/search/label/4pcb

tinyKart is our ultralight electric go-kart. It currently weighs 55lbs with a final target of 53lbs. The top speed is 30mph (controller limited). The custom chassis is made from aluminum plate and extrusion. It's propelled by two 2kW RC airplane motors and two electric bike controllers. The battery is a 37V/9Ah lithium polymer pack weighing 6lbs. The range is unknown.

This is the first test drive of Pneu Scooter, an electric kick scooter with 6" pneumatic wheels and a custom rear hub motor. It's version 1.-1 because, for this test run, it's running on an off-the-shelf brushless DC electric bike controller. In the future, it will have custom synchronous AC control.

Here are two of the first test-spins of the custom pneumatic wheel-motor for my latest scooter project. The motor is a three-phase brushless outrunner, designed for about 1600rpm at 33V and a peak torque of about 5ft-lbf. The controller is also custom, a 48V/1kW field-oriented synchronous AC drive that still has some software? glitches to work out. More info: http://scolton.blogspot.com/search/label/scooter.

Cap Kart 2.0: 8/21/2010 Test Drive

This is our second test drive of the new Cap ...

This is our second test drive of the new Cap Kart. The first run ended similarly to the first test drive: with a dead MOSFET in the controller. This time we came prepared with a field soldering kit and a less volatile replacement FET. After that, things went smoothly and we got a good chance to test the various improvements we implemented this summer. These include: - Thundersky 40Ah lithium iron phosphate batteries to replace the old lead acid batteries for a weight reduction of about 100lbs. - A custom rear axle differential based on design from LOLrioKart (of internet fame). - New field control modes for the separately-excited DC motor, including "three speed manual", reverse, and continuous field weakening. - Better data visualization and logging, plus fault detection.
