Some prior electronics and programmable microcontroller experience required (the REC microcontroller seminar is acceptable preparation).
Assignments, schedule, syllabus (tentative):
|3/12: Intro to motors, power supplies, motors running @ diff. speeds w/ diff. voltages, gearhead motors, diff. sizes||3/14: switches. SPST. SPDT (with dual +/- supplies). DPDT. relays of all these sorts. protection diodes. solid state relays.|
|3/19: linear transistor driver. emitter follower. linear driver + DPDT switch or relay. Power dissipation calculations.||3/21: Driving a relay with a PIC. noise considerations in microcontroller circuits. more relay stuff.|
|4/2: switching FET driver w/ PIC PWM. also w/ a DPDT relay.||4/4: 6-fet h-bridge!!! (w/ no short-circuit protection)|
|4/9: adding software and hardware protection to a 6-fet hbridge||4/11: steppers, hobby servos.|
