What has been won by the brave at great cost can be lost cheaply by fools and once gone can rarely be regained and only then at great cost.

After playing with it for a few hours I decided I don't want to use that controller.

The controller doesn't seem to be a speed control so much as it is a sensor-controlled on/off button. But I cannot discount the possibility that the pulse width might be varied - though if it is then I didn't notice it with my un-loaded bench test.

I've got it rigged-up to another PWM controller I liberated from an expired E-bike. And it works very well.

I also found that while using the speed control, you can bridge the motor's negative to the battery negative then you get full power - sort of like a turbo. The good part about that is that bridging the controller doesn't destroy it. :)

The original controller has four very chunky-looking semiconductors and my plan is to make a new driver for them - I'll make it with an astable multivibrator because I'm challenged with anything else. This should be relatively easy, don't you think?

Maybe I'll see if I can remove the two semiconductors in the E-bike controller I've got it wired to and put the four larger ones from the original controller in instead?

* Velly solly about pics! I really want to! Once someone holds my hand and teaches me how to do it then I'll inundate the place with videos and my pics. My computer is Japanese and I can't do much with the programming. I can speak Japanese all right but I can't read it much. - And my wife can read the programming jargon but she needs me to tell her what it means. *sigh*

The sensor was most likely a magnetic Hall effect sensor,
and the gear had a magnet in a drilled out hole sir...

Sh*t!

I wasted the best part of an hour on that reply! It didn't go through and vanished when I tried to post so I couldn't copy it.

Aaargh! It really hurts when that happens.

Apparently it is necessary to use a word
processor to create the commentary then
paste it in to the reply when needed to
avoid loss when things go awry. But who
remembers to do this until disaster strikes?

Here's hopin' you'll try it again Mael...
