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 is a super simple short range AM radio transmitter that uses only 3 parts. It is made using a modified ‘Cool Joule’ led light circuit that was first presented here by TinMan.
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…
This is a super simple wireless device that can broadcast the headphone output signal from a laptop computer to a nearby AM radio. I call it the ‘Cool Joule Radio Transmitter’. The circuit is…
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…
This is a simple one transistor short range FM transmitter. It runs on 3 volts and the circuit is based on one that saw here on Youtube. The circuit was put together with parts…
Some video of me playing with a Tesla coil transmitter. Tiger joins the fun at the end.
This shows what the output signal of my ‘Cool Joule Transmitter’ looks like on a computer based oscilloscope. The o-scope probe is not directly connected to the circuit. A small coil of wire (sniffer…
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…
This is my ‘Cool Joule Transmitter’ using the house ground wire to transmit a wireless audio signal to different locations inside the house.
