IR Tachometer

IR Tachometer PUBLIC

Infrared tachometer used to measure fan speed by providing an interrupt to an Arduino. The goal is to synchronize two fans.

Motor_Drive

Motor_Drive PUBLIC

Circuit to drive low power DC motor (indicated with an M). In reality the circuit draws too much current from the digital pot meter (which becomes very hot and stops to work properly).

hs-hbridge PUBLIC

This is a 24 Voltage h-bridge motor controller, it performs high speed switching(maybe high) for PWM controlling and within dead zone protection....

servo amp 2

servo amp 2 PUBLIC

An extension of servo amp 1. Note dead zone insures no "shoot through" or "cross conduction". For bi-directional motor drive or thermoelectric cooler drive.

servo amp 1

servo amp 1 PUBLIC

Drives high power loads with small control voltage. Note "dead zone" near zero. This is to eliminate "shoot thru" and guarantee both transistors can not on simultaneously. Not recommended for audio...
