49MHz Walkie Talkie -  Lots of people are requesting walkie-talkie and RF remote control schematics, so here is some. Building se circuits needs special equipment and expertise in RF circuits. If you are going to experiment with se circuits, please note that I did not build.... [Peter Jakab, Electrical Engineer, Engineer of Informatics]

Balanced Transmitter/ Receiver -  Updated and upmarket versions of the Balanced Line Driver & Receiver balanced circuits ....
DIY remote control based on PIC -  Control up to 8 devices by this easy constructable remote control. It can work as a radio or infrared remote control, depending on the components. Each device output…. [Peter Jakab, Electrical Engineer, Engineer of Informatics]
HAM Radio BFO -  circuit diagram of beat frequency oscillator using BF494 and how to listen amateur radio communication on ordinary BC receiver..(added 01/05)

HeNe Laser Transmitter/Receiver (Aaron Cake) -  (circuit / schematic design added 7/02)
Infrared Transmitter & Receiver Schematic Diagrams -  ....
Laser transmitter/receiver (Aaron Cake) -  This set of two circuits from the basis for a very simple light wave transmitter. A LASER beam is modulated and then aimed at a receiver that demodulates the signal and then presents the information (voice, data, etc..). The whole thing is very easy to build and requires no specialized parts execpt for the LASER itself....
Remote Control Encoder/Decoder with PIC16C620 & PIC12C508 -  (electronic circuit added 09/04) [Peter Jakab, Electrical Engineer, Engineer of Informatics]
