Graham Gunderson's Energy conference presentation Most impressive and mysterious

[gotoluc]

Yes Ben, we have to down size pictures here before we post them or else the topic page size gets to be a problem.
Just open the pic in Windows Paint and click on re-size and select pixels and make them 800 to 1000 max wide and save.


Attached is a 1000 pixel re-size


Are you going to try the dual (bi-directional) mosfet's?


Thanks for sharing

Dear Luc,No Problem with the oversight, is happens all the time, even at VW.
Would the requirement of a bi-directional switch in your circuit imply that the H-Bridge configuration will be a requirement in the Gunderson Circuit?

Seeing my oversite now, my best guess is this would better support the use of an H-Bridge in Graham's device.

OK.... er.... hmmm.  I breadboarded the circuit, sort of, and got some pretty strange results. It's a weird sort of window-oscillator, kind of unstable, but I finally got some consistent results out of it.

Dear TK,

I might have missed a component (or connection) in my take off so it is amazing that you got that circuit to run at all on the first go around.

An oscillator makes good sense since it connects to the H-Bridge ring timer just above it.  I was wondering if I was going to find out where the master clock was hiding.

Good work. I know that these distractions are taking time from your main project.

Well, I didn't exactly get it to run "the first go round". And I'm not sure still whether I'm seeing the actual quasi-stable performance of the circuit or just some weird breadboard artifact.

But my "main project" at the moment is just trying to get some sleep. And I haven't been sleeping very well lately anyhow, so doing this stuff isn't really distracting. Much.

It's a weird way of implementing an oscillator though.

All,

Sorry about the oversize picture, forgot about downsizing on my MAC.
