Pulse Motors: MagSpinner 1: Input Power Measurements
Here I show an input power measurment on the MagSpinner v1. The difference between the power input when magnet is spinning, and when it’s not, is demonstrated. I put a 1 ohm current viewing…

Scoposcopy: Measuring Frequency With The Analog Oscilloscope
Quantitative frequency measurement with an analog scope? Without numbers in boxes? (by request… thanks shubus) Well, we did use one number from a box. You need some kind of external frequency standard so that…
Joule Thief: PCBJT Wirelessly Powered by SassyClassE SSTC
I’ve dusted off the SassyClassE SSTC for some experimentation, and I happened to discover an interesting thing. I can easily light up little LEDs near the coil using various hookups, but I was surprised…
Pulse Motors: MHOP #11: Some Instrumental Data with Load
Here I show the effect on the input power measurement of adding a small electrical load to the PTO terminal of the MHOP. The motor is also turning a small electric airplane propeller and…
Electric OU: Data and Results: 4Q2s Oscillating, 60V, Figure 3 Mode
Erratum: At about 0:48 I describe the waveform on the DSO as “no Q1 on time” or something like that, where I should have said “No Q1 Current during the Q1 ON portion of…
Electric OU: Supplement: DMM Average Current Checked w/ Scope
The DMMs are known to be pretty good at averaging. Here I compare the average current during one full cycle of the input current waveform, read on the scope by voltage drop across the…
Electric OU: How DO Mosfets REALLY Work? Bias Current Runs Common Gate Amplifier
Once more for the LULZ. The common gate amplifier is evidently more mysterious than a pot of stone soup, but if one pays attention one may begin to become enlightened. This video is a…
Electric OU: How DO Mosfets Work? NERD Circuit Q2 Remedial Part 2
Please watch the first one first. The 9v bias battery is removed and the Function Generator is substituted in its place. The light bulb is shown to light just like it did with the…
pt2 TMT Tesla Magnifying Transmitter Slayer Exciter 24 hour Update
looking good, for some reason the operating current waveform thru the 1 ohm resistor has gone up from .442 A to .476 A , which can’t be the correct DC current, but interesting all…
Electric OU: Supplement: Negative Biased MOSFET Oscillator Part 4c: RF Power
Part 4c: Please watch Parts 1, 2, 3, 4, 4ab first. Thanks! Here I take the circuit from Part 4, the basic common-gate oscillator, and demonstrate that it is radiating significant RF power. A…
