WARNING: HAZARDOUS VOLTAGES. PROFESSIONAL IDIOT IN CLOSED ROOM. DO NOT ATTEMPT. YOU CAN BE KILLED IF YOU MAKE A MISTAKE. DISCHARGE ALL CAPACITORS BEFORE SHOCKING YOURSELF SILLY. I was driving around on the East…
This shows one of my cement batteries running a Hartley Oscillator AM transmitter. This oscillator circuit operates on extremely low power and can transmit a few feet. The circuit diagram shown here was posted…
This is a simple AM radio transmitter that uses a 1MHz crystal oscillator module and just a few other parts. You can find info on this at SciToys.com. My first attempt to build this…
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…
A small dish receiver is used for wireless energy transmission tests. Distance between transmitter and dish is 4ft. The dish itself comes from a toy helicopter setup. The unit used to be used for…
I’ve given a name to the Negative Bias common-gate oscillator circuit. I call it “Little Bryan”. Here, Little Bryan is used as an AM radio transmitter, modulated by gating the Function Generator with a…
This video shows how the “Pancake coil JT” can be used as a short distance AM radio transmitter. I also show how I used a “radio direction finder” method to help navigate to Hawaii…
Scalar longitudinal EM, linecast into a Faraday cage and received by a LW AM receiver, at 174 kHz. In one of the wireless power videos I show that this improvised Faraday cage completely blocks…
Here is a demonstration of wireless energy transmission using a cast iron kitchen sink to provide a ground for the receiver tower of the system. I am using a standard Dr. Stiffler SEC that…
