RF Transmitter

[slayer007]

Here is a weak RF Transmitter circuit.

It can be made stronger by replacing the 270 ohm resister with a differant value.

Here is a video of it I made yesterday.

In the video it wasn't working to great.It had a short in one of the wires and wasn't transmitting my voice to well.
But now it is working good and transmitting very well.

Aah I remember when I used to make a few of those as RF bugs

A slight improvement on your schematic would be to put a tap on your coil. It allows you to amplify it a further step and isolates it so when you touch it, it doesn't lose stability.

Its a pity small transmitters' ranges suck so bad.
What would be cool is to somehow make a "Tesla wireless bug"
