#9 ~Russ’s Filament Extruder: Making “The Puller” & Demo Of A4988 Stepper Motor Driver. in this video i build a filament puller for my extruder. i also show how the A4988 stepper driver works…
Testing out my new Variable Power and Variable Freq driver i built for the Smith project. I basically built a variable version of Don’s NST 🙂 Using a 555timer with added Lm393 to give…

We’re finally there. True toroidal power amplification TPA that can be easily replicated… Watch this
Here a very interesting experiment which shows the current lag in the toroidal coils of the stator while the rotor magnet is turned by hand. This is a good method to wind the position where the coils must be energized by the controller.
The treasure:Toroidal coil winder Made in USA – Not contaminated with counterfeits from China .
This is my large carbon and magnesium battery powering a flyback transformer circuit and lighting a 110 volt LED bulb to about 1/3 brightness.
Hi all This video is intended to the contributors at OU forum under the Kapanadze thread. And of course to all the other people interested in this matter And specifically to Wattsup which proposed…
simple way to get a nice spark without electronics (TROS), just a dimmer (triac) and flyback; variac is optional notice single wire ground connection – strimmer in SG is forming FROM ground
