Pulse Motors: MHOP Development #10 : Power Takeoff, Simple Neon Ring Oscillator

The MHOP produces the usual high voltage spike when the coil is switched off. This spike is what lights the neons, but can be “siphoned off” and used to power external devices, charge capacitors…

Bruce Forrester’s Multi-Wave Oscillator Antenna

www.americanantigravity.com – Bruce Forrester describes a multiple-wave oscillator golden-ratio antenna he’s developed based on the Fibonacci series for holistic mind healing applications. NOTE: This footage contains severe audio interference in the last 10 minutes.

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…

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…
