Selfcharging cap circuit from Larskro fake or real ?

Video posted on March 12, 2012. Old news. Not a self runner. You are really good at misrepresenting the work of others, while not showing any work of your own!

Look, He states that he watched the motor run for six hours untill he got bored with no drop in input voltage. What more do you want?

I want you to do some work of your own for a change.


Meanwhile, I found that I can use one of my ordinary reed relays as an externally-actuated reed switch. So I made a driver board for the MiniPulse to test it. Since the reed is attracted to both polarities of the magnet it makes kind of a funny motor driver, but with biasing the reed so it prefers one pole only the motor runs. It runs incredibly well on just 2.8 volts input.... when everything is positioned exactly right. There is enough backspike, even from my little aircore coils, to flash a neon. It also periodically welds the reed contacts closed, but by beating on it I can unstick them. I'll be making a video a bit later on, but here's a still photo of the reed switch driver board, with diode, capacitor and NE-2 neon.

The relay is Elec-Trol RA30421051, SPDT contacts, 5 volt coil, without a diode across coil! But of course in this application I'm not using the coil at all, although it might be possible to make it work as a bias control with a tiny bit of current.

This is amazing. I've found the sweet spot for the reed switch and bias magnet, and the motor runs at over 11000 RPM with 2.7 volts input... but here is the amazing thing.

Right now it is running stably at 575 RPM..... on 0.243 V and 0.037 amps input.

Here's a few more to help:


"Put a tie on!"

"Take the trash out!"

"Get a Job!"

@Tinselkoala,


                    Alright, now where did you the hide the hampster, Mr. busy all the time big guy? Now all that's left to do is to get it to self accelerate, like I did around ten years ago, and Larskro too.
