A function generator is a clocked, positive-negative power supply with an internal impedance of 50 ohms. You can add offsets to the FG’s output, just as if it were a battery or power supply,…
Yes, Virginia, they do. The Interstate F43 is set to make a square wave at a slow frequency. The WaveTek Model III is set to make a sine wave at a higher frequency and…
A simple circuit describing high-side switching using a random N-channel mosfet. Also showing that the gate needs only Charge to switch and if the Charge stays on the gate it keeps the mosfet ON….
This is a simple zinc & copper earth battery that I made out of common pot scrubbers. The battery is partly burried in my flower bed and is shown running a simple pulse motor….
During the major Midwest storm of 10th April, the 2 oscillators lost the regular 1:1 flash rate sync that they had held for weeks. Slowly but surely however, they regained their sync and from…
Some more tests with BEMF. Playing with coils and transistors have made Bedidni SG running from 1.5v bttry. And seems it can run straight from bemf of RS bracker from Adams motor (bemf pulses charging 5V 1F supercap from which SG is running). No worrie…
Very interesting observation. Instead of using a capacitor I’ve just shortened collector to prime bttry through diode and got looks-like self-charging mode; system keeps 12.18V, magnet running steady, and only after 2hrs it started decline very slow; b…
MY LENZLESS GENERATOR BEING RUN BY 1.8 WATT MOTOR AND SHORTING COILS DEMONSTRATING SPEEDING UP UNDER LOAD VS NO LOAD. ALSO REMOVED JUNK LEFT OVER FROM HOMEMADE MOTOR. THE POINT OF THIS GENERATOR IS…
Here’s a neat thing I discovered about these little piezo buzzer elements. I knew they would flash the LED, but evidently they also somehow hold enough charge so that they are able to flash…
2 kW genset running on paint thinner (Dupli-Color, Specialty Reducer) and used motor oil (mixed together in the central bubbler). (No first Evaporizor, results in not as much control). Adjusts speed by adjusting valve…
