The following instructions detail how to build a simple pummer using a BC2 (Bicore) BEP (Bicore Experimenter PCB). A pummer is a solar powered self activating LED flasher. The difference between a pummer and a BLFNAR (blinky light for no apparent reason) is that a pummer has a soft turn off, which means that it turns on fast, but slowly fades away.
Escaps back in stock!

Well, the last batch of Escap gearmotors went very fast. Let's hope this batch lasts a bit longer!
Unlike the last set, this set has a higher reduction ratio of 663:1 instead of 362:1. This means it starts turning 0.46V (!) drawing only 3.3mA (!!)
It's a 3V rated motor, but our tests show that they spin quite nicely at 5V, drawing 4.2mA free (!!!) at 22rpm. Don't know what the stall current draw is, as we're scared to strip these delicate gears, but it's greater than 150mA. Check them out!

BEP Application: Servocore Walker
The following instructions detail how to build a Servocore walker. A Servocore walker differs from a regular walker by utilizing the internal electronics in unmodified servos, which give position feedback from the motor in the servo. This position feedback allows for very long stride lengths without the use of mechanical stops or springs.
