Get you some of that, it bites!
Why the raptor theme? It's got absolutely nothing to do with raptors but everything to do with my Gamertag RaptorZN.
So what's this web site all about? Most importantly to share my technology interests with other technofiles ... otherwise it's here just for the fun of it.
In the Relics Section is a mixture of some of my favorite hobbies and associated projects covering everything from radio frequency (RF) transmission and reception, antenna's, graphic and web design, illustrations and sketching, radio controlled (R/C) aircraft, Visual Basic programming (for RS-232 port) and reception of weather satellites.
My Blog features some of my ideas, thoughts, opinions, reviews and interesting news. There is an entire section for news about Karol Madera VE7KFM or better known as Radio Canada (one of the most infamous radio amateurs around). Also posted there are details of a very interesting, potential UFO sighting of my own, i.e. Orange orbs and gigantic crescent shape object seen over The Reeds, Centurion, South Africa).
I hope you enjoy your visit!
FM Stereo Transmitter
Build this FM stereo transmitter using mostly Op-amp's. Disclaimer: Build and/or use this device at your own discretion as it is illegal to operate a radio frequency transmitter without an appropriate license in most countries.
Wideband FM broadcast band jammer
Here is a design of a fairly simple, but effective Wideband FM broadcast band jammer. Disclaimer: Build and/or use this device strictly at your own discretion as it is illegal to operate a radio frequency jammer in most countries.
HF Band QRM/QRN Noise Canceller
Build this HF Band QRM/QRN Noise Canceller which nulls out and attenuates RF noise and interference with up to 40dB (typical).
The radio frequency (RF) band is packed with information. Listed here are frequencies of local, international, amateur and satellite transmissions.
