Joule Thief: Practical Application: Simple NPN Transistor Checker

The JT Basic circuit is used with a 1n914 (or 1n4148) diode in place of the Base Resistor. Cathode towards transistor Base. The circuit is the Basic 2n2222 or 2n3904 JT, available everywhere. the…

Arduino 9: Driving a Bipolar Transistor: 2n3055 As Light Dimmer

Another application of the simple, sensor driven voltmeter. The 2n3055 bipolar power transistor is used along with the Arduino’s pwm output to function as a sensor-controlled light dimmer. The photovoltaic cell is still useful…

Magnetic Resonance Amplifier: Experiment 1, Random Parts

Here I’ve taken the basic “Magnetic Resonance Amplifier” idea and approximated it with materials I had on hand. The device does show some interesting effects. Are these different than one might get with a…

Electric OU: Supplement: MOSFETs… How Do THEY Work?? Parts 2 and 3

An N-channel mosfet is used to demonstrate turn-on from a small gate charge, and then the linear operation of a mosfet is demonstrated to show the difference between a SWITCH and a linear amplifier…
