Guruji,

This is a devleopment of the well known Dave Lawton twin 555 timer based PWM.

This device generates a varying signal seeking a resonant point and then locks on to it. It is based on a HEF4046 Phase Lock Loop IC.

Richard

Thanks for this

Eric,

Yes this information does help thanks. Maybe if I'd taken or found the time to read the whole thread. Too much to do and not enough time.

I find the Express PCB or Eaglecad format's alot easier to follow as somebody who doesn't design PCB's for a living.

I'd also like to thank adam_mizer for his helpful PM as well.

Regards

Richard

I can't open the pdf files

bussi04,

I tried opening the pdf files in that thread but wasn't able to open them.

I ask about the Dave Lawton circuit as I have had a couple of prototype PCB's made up and the initial test result looks quite good.

I'm not aware that anybody has tried this circuit andwanted to discuss results with anybody who has.

Regards

Richard

Good Evening All,

Has anybody built the circuit developed by Dave Lawton as posted on p.46 of Patrick Kelly's latest Chapter10.pdf document?

Regards

Richard

Getting these VIC parts made
