This is a low cost microprocessor pulse width modulation circuit to replicate the 555
timer circuits of the Dave Lawton’s
The Hydrogen Shop
Micro Star PWM
The Micro Star
The computer chip on the board is timed by a 20MHz crystal oscillator. This is the clock that sets the time base for the Pulse Width Modulator. All the timing characteristics of the pulse width signal, e.g. frequency, duty cycle, marked spacing, etc. will all be controlled by the Processor.
The computer will give a direct read-out of the frequency back to a small LCD screen. The user can therefore adjust all these parameters at the touch of a small 12 digit key pad.
The computer will deliver the REStar module PWM signal but also replicate the Dave Lawton pulse width modulator circuits and the user can quickly switch between either one of these modes and adjust all parameters of these modes.
The unit is called the Micro Star and is Now in production. .It is relatively cost comparable to the REStar module.
The Nova Star comes as a standard fitted unit to the Micro Star WFC-020.
