Schematic RC Pulse to PWM Converter Project

This Project describes an AVR chip and software that converts two easily formed R/C pulse signals and converts them into a PWM signal suit for driving small motors. This will be good solution for common problem for hobby robotics when controlling the drive level to a motor. As many hacked R/C servo's are used have poor control range. And...

Beam Robot 3

B.E.A.M –botThe trick is to design a circuit that detects whenever the capacitoris fully charged. There are a lot of solutions that can be found onthe Internet. A nice idea is to use the voltage drop across a flickerLED as it depends on the amount of background light. It's 2.4Vbut slightly changes in darkness. The result is a creature which...
