Eldarion and Bruce's build of Bob's Energy Converter

Which also reminds me of what Sauron mentioned once before:

"if we have a powerful magnetic wave present @7.8 Hz and we make the coil cancel one half of the wave , the other half will "hit" the coil which can result in a vibrating "shock" effect and the output will be the other half wave , so basically a alternating half cycle which could look like a pulsed DC is some fashion."

hmmm...must have missed this one...

This was in a PM that he sent me .

Thanks for sharing.

Hello all,

As some of you already know, I recently acquired a Tektronix 500MHz digital scope--this has allowed me to see an additional pulse generation problem with my FPGA-based controller.

For an unknown reason, it generates a perfect pulse sequence on each of the channels, but only for a certain number of cycles, with dead time in-between!!!  It looks like I have never actually fed the correct sequence to the coil, ever.  (This type of problem is nearly impossible to see without a digital storage oscilloscope with enough memory; hence the reason I never saw it before.  On an analog scope everything looks perfectly fine, even though it is not.)  Just to add to my befuddlement, the Verilog pulse gen code does not have any errors in it, so it must be Xilinx's synthesis tools acting up again.  I am not impressed with Xilinx's synthesis program in many areas; you can guess why!

So it looks like another rewrite of the pulse generator is coming.   At least I know what the problem is, finally.

Hey Eldarion,

Great to know that you figured out what's up now. I'm very excited to see how things will go for you once you input the correct frequencies!

Keep up the great work; we're all rooting for you!

God Bless,

Hi Eldarion,

I hate to say it, but this is one case where bad news is good news!    

Now that you have diagnosed the problem, perhaps the smell of sweet success is ahead...

No way to get those shock waves Bob described, without the correct pattern as everyone knows.  So this is very encouraging indeed.   

Warm regards,
Bruce
