Re: Discrete Pulse Width Modulator
Well, here are the test results from the latest version breadboarded. Not too clean, needs a little 'tweaking' but worked on the first try!
I used 2n4401/2n4403 for all transistors; R7/R8 voltage divider was replaced with a 500k pot
Next, I will build a Color Organ using this circuit to drive LEDs
Please, as always, I would really appreciate any comments on what you think of it and any suggestions to further improve it.
PS: Since it was breadboarded, the freq was not too stable
