UUS 65 - 73 MHz fm transmitter
A basic UUS 65 73 MHz fm transmitter circuit schematic which can be used as uus oscillator with no explanation …
65 - 73 MHz transmitter ( oscillator ) circuit components:
L1 = 8 t / 0.3mm / 6mm
L2 = 8-12 t / 1mm / 15mm / 1mm gap
SRF = 60t / 0.2mm / 3mm / ferrite
FM Power Amplifier BLY87A, BLY89A, KT920A, KT925B
A very simple fm power amplifier which can deliver 4W rf power with 12V power supply and BLY87A or KT920A and 20W with BLY89A or KT925B.
If you use BLY87A or KT920A the input power must be 0.5W and 4W if you use BLY89A or KT925B. This fm power amplifier is designed to work on 50 Ω antennas and a maximum power supply of 14V and in 88 108 MHz band.
Use only metallic trimmers, a good heatsink for the transistor and ceramic capacitors and keep the pins very short.

Stun Gun simple schematic
This is a simple stun gun circuit schematic just for learning! In No Way Do I Recommend Building these Stun-Guns or the actual use of them for any purpose what so-ever.
We will present more stun gun schematics but in no way we recommend you to build it, I Assume NO LIALIBITY for any resulting actions of those persons who build or use any of these devices!
This stun gun delivers 50.000 Volts and produces high voltage pulses discrupting muscles and nervous system, leaving anyone who touches it in a state of menthal confusion.
The stun gun circuit schematic:
