Arduino 8: PV Sensor Output to Seven Segment LED
Bar graphs are so last century. This is Century 21 ! The omnidigital error…er, era. If it don’t have numbers in boxes, it don’t have squat. So here I show how to adapt a…

Electric OU: Supplement: Part 5: Current Flow in the Full Circuit
Here, finally, is Part 5. I’ve added a Q1 mosfet and I’ve placed a DC milliammeter at the Battery Negative pole and a DC Voltmeter monitoring the Red FG output lead which is connected…
Arduino 4: TKVoltmeter, Potentiometer LED Sweep, Circuit Controller
Here I use the example sketch called “arrays” and blended it with the “potentiometer” example from the basic Arduino library with some simple modifications to serve as a potentiometer LED sweeper, which can also…
Arduino 7: Switching a Heavy Load Using MOSFET and PV Sensor
Here I continue to demonstrate the versatility of the simple Arduino pot-voltmeter system. NOTE: I get scrambled when I describe the mosfet pin hookup. The Load has no connection to the mosfet gate, it…
Arduino 5: TKThermosensor w/ Alarm, Airflow Sensor
I used the same circuit arrangement as in the last video but with the addition of a piezo speaker element. A negative-coefficient thermistor is used along with a 1K resistor as the “potentiometer” sensor…
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…
Free Energy Project – Input and Speed Test 1
This DC motor is sooo much better. Plus, now everyone will see what I’ve been seeing with my eyes. Even with the voltmeter as a tachometer, we will see very clearly what percentages we’re…
Extreme High Voltage: AnAtmoSphere Flyback Power Supply Voltage Measurements
Plasma is highly conductive. I pity the fool … who has to design high voltage apparatus for spacecraft. So I dug out the Singer – Sensitive Research 15kV HV moving-coil voltmeter to make some…
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…
bemf “quest for OU”VII
Very interesting observation while playing with bemf pulse motors (the idea’s to make enough thrust from magnetic pulse motor powered by 1.5v bttry to spin light generator, making 0.01more watt of power than spent). So, as we can see the bemf creating …
