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.

Fm power amplifier 50W BLY94
This fm power amplifier circuit is built with BLY94 transistor which delivers up to 50W at 175MHz and has a power gain of 7dB, arround 5x power amplification.
But in this schematic bly94 is working in 3 meter band, FM 88-108 MHz, so it has a higher power gain, 8dB - 6x. So if we use a good quality trimmers and coils with 7W input rf power BLY94 will deliver up to 50W rf power. If you use it in C class dont connect R1. The power supply must be 28V stabilized and must support a minimum 3.5A current consumption at 7W input rf power.

Tv antenna amplifier circuit schematic 1
A very simple and cheap tv antenna amplifier circuit built with BF961 a N–Channel Dual Gate MOS common transistor used for input- and mixer stages especially for FM- and VHF TV-tuners up to 300 MHz.
Bellow you have the antenna tv amplifier schematic and here is the BF961 datasheet.
L1 = L2 = 5turns / 0.8mm Ø / 5mm Ø / the second turn from ground.
This tv antenna amplifier can be used even as an fm receiver amplifier because it has a wideband amplification, so if you dont use it for the tv set you can receive better your favorite radio stations.
