LM317T Voltage Regulator with Pass Transistor

This is an update on my voltage regulator oscillator.It will now run on a wide input range and the full output of the regulator is available for switching or pulsing applications. I also show how the VRO can be used to make an inverter and an exciter.

This is a very simple oscillator which uses a TS 2950 3.3V voltage regulator to light an led and charge batteries.It takes advantage of an unwanted characteristic of some voltage regulators which is oscillation or noise and i use this to pulse a coil.A more complicated setup with a 1:1 bifilar coil is also shown and this produces a higher voltage (even above supply voltage) than the voltage regulator supplies under normal operation.

This is more work with Jonny Davro's "Voltage Regulator Oscillator". I show it here running a spinning magnet on a mirror.

This is Jonny Davro's "Voltage Regulator Oscillator". It is a simple oscillator using a 3.3v voltage regulator and a coil. I show it here running one of my low voltage pulse motors.
