A simple but flawed idea to make a fixed frequency variable duty cycle oscillator based on a 555
timer and using the push-pull output to drive the RC timing through two routing diodes, a pot and a
series resistor to limit the min/max duty cycle to something sensible at around 9%/91%.
If the diode drops were negligible and the 555 timer output pulled fully up to VCC and down to

This circuit will power a small DIY induction smelter. The induction coil, coil power, and circuit power will all be external. In addition, this circuit has been tested on [ www.falstad.com/circuit/ ] and it seems to work great.
Within the circuit, U1 (a 555 timer) will create an adjustabl...
