Computer Control of a PWM design. work in progress.

Hi Feynman:
My computer just flopped. I was trying to buy :  LM741 and a TC4420CPA but I had better wait.  The circuits that you guys are working on looks good and is better than ever.  One question:  will we have to have a laptop and oscilloscope to dial this system in?

thats a good question lefferdink:) thanks for asking it

the Simple answer is NO . the point of publishing my work is to allow all of us and our expertize to cut out tuning needs.. the system will have maybe two main settings. one setting for conditioning the cells.. the second for running the system at its full potential....

an oscilloscope would be handy if u wanna see the working of the design.. but not needed..

Hard luck too on the Flopped pc. Wat killed it?

Hi Lanmasterd:
The hard drive took a dive; so I hooked up the 80 gig that was sitting around.

Agreed, I don't think you will need an oscilloscope if the microcontroller setup is working,

But oscilloscope helps with troubleshooting.    There are cheap ones on ebay if you look hard enough.

Hey lads still working on stuff dont worry .. ive been sick and in bed most of the last week with not my mind for my laptop.. and my pcb exposure unit broke..pain and rage thing lol.. but im gonna have to rebuild my pcb unit .. anyway im on anti biotics for another 7 days i cant drive and my missus is making me rest as much as possible,, but im perfecting my design digitally.. .. 

Question should we maybe add ground planes where ever possible to reduce the amount of pcb we would have to etch.. just a thought ill do up two versions a no plane and one with a plane...
