ElectroJolt I am impressed.

I assembled my PWM, had a single problem and was the fact that I put in the wrong resistors for R6.

Once I installed the proper resistors 2.2k in those 3 positions this PWM worked better than I would have thought.

My signals are much clearer and accurate and think this is due to a combination of your circuit and the fact that I am using a couple 100k precision pots.
I have to say the precision pots react with precision to the scope displayed waveform. Much more tighter tuning is available for me now.

This PWM blows the socks off my home brew Lawton pwm.
I am running at a more controlled current now because of the duty cycle.
Adjustments are much easier. Signals are cleaner for me.

Signaling options with 3 channel control are now possible.
I really think this is a bonus, the options I now have with 3 channels of this PWM.
Oh yah and the channel switchs can add control to the channel I'm currently using. An added extra.
Don't think you need to because its pretty darn nice as it is. Great to have the added abilitys though.

The fact that the signals were very clean added to my inductors now I'm able to blend some harmonics.
From the bounce factor of the inductors I get a clean scope display and can see how the waveform multiply's inside.
Don't think I was able to see this before with such clarity on my scope.
The clean signal and stabilty now allow me to actually see the waveform I'm making with the inductor harmonics and manipulate it.

I highly recomend this PWM to everybody that has a basic standard Lawton type or homebrew 555's type.
This was definately a step up for me.

More options and clean signals.
NICE!

Thanks Komtek for the kind words,

I'm glad you like and using this circuit.

I have been getting some PMs asking for the PCB file,

Let me tell a little story and why I will not be posting the file:

2 year ago +- , everyone wanted a good and reliable EFIE, so I designed one, tested it, proved it that it works, it took me 3 month working on it, I then published everyting so people could build it for them selfs. Well some guy stole all my stuff and started to sell it as if it was his circuit. I got very upset, I spent 3 month of hard work, and now that jerk was taking credit for my work.

this is the * : http://www.hhogear.com that stole my circuit.

I confronted him, and he said he never saw my circuit and that was his idea...... what a bunch of *

Google: claudio cabete efie

So because of this I will never publish the PCB files, If someone is going to steal my work, they will have to spend time designing the PCB them selfs.

Now  some of you here know that this post does not apply to you  ;)

Claudio Cabete aka Electrojolt

Dam those guys are crooks .

Gotta watch for em , they wont go far without the pcb file .
