Effects of Recirculating BEMF to Coil

@TK
Sound good TK let me know how the circuit works out.

Thanks for taking the time to help

@.99
That also sounds good .99  the only thing that is a problem is the IR temperature meter laser is not aligned with the sensor. You can see me struggling with it in the videos to find the right point and that is with those large ceramic resistors.

I hope the data will help

This is my last post for today.

a user at Energetic posted this interesting test idea and I would like to know your opinion on this .99 or TK since I don't like cutting up my coils if not necessary

Suppose your coil had several TAPS ... one at 50 turns, one at 75 turns, one at 100 turns, one at 125 turns, etc. etc. etc.
Now from each of these TAPs, bring a diode out and route it back into the
coil.
That will really piss off the magnet. :-)

@gotoluc

I also agree with @poynt99. If someone grabbed an image of the bulb each time you made a change and blew up the image and put them side by side, I am sure there will be some differences. At that low brightness level, a small change could easily mean 50% more or less and it would still be hard to make out the difference visually.

Also, during both video tests was the return diode on or off. This was not clear to me. It may have been good to switch it in and out to see the difference at each setting. But very good work.

Luc,

I wouldn't go hacking up my coil just yet. At least until after my next post if you're still tempted.

To be honest though, I think it would amount to the same degree of boost as the single feedback point as you have it right now anyway.

When I wind mine I'll put taps in.
