Dankie,

Please tell us why you think it is not worthy of our consideration.

Thanx,

Jim

- relatively small frequency range
- why would anyone need 10Amps?
- is the duty cycle stable or varies with frequency like dave lawtons?
- huge box, we are not in the 80s, there are computers nowadays
- 100$?

Its a normal Dave lawtons probably , it can be made @ home for 10$ if you know how to follow a schematic and solder .

Then again it's enirely possible that he could have used an EXAR XR2206. (Dave Lawton used a dual 555 setup.) That particular Function Generator IC is incredibly and wonderfully inexpensive and  will go from 1 HZ to 1 MHZ.  Pin #6 would be used to connect three capacitors thru a 3pole single throw rotary switch or equivalent.  Each cap would select a dual order.freq. range. I.e. #1:::::1 - 100HZ; #2:::::::100 to 10KHZ; and #3::::::: 10KHZ to 1MHZ.  The fine tuning control is connected thru a 100K ohm pot at pin#7.  I've got  atube full of these ICs sitting on my bench just waiting an application.  One of the many benefits of this function gen. is that the frequency does not change when adjusting the duty cycle.  It'll do Sine, Square, and Triangle waveforms.

Dankie why wont you post here your super pwm schematic?
