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 __ Designed by Peter Jakab, Electrical Engineer, Engineer of Informatics

Balanced Transmitter/ Receiver -  Updated and upmarket versions of the Balanced Line Driver & Receiver balanced circuits  __ Designed by Rod Elliott  ESP

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 can be configured to be momentary (turned on while you press the button) or latched.  Latched outputs can be toggled on/off by one button per channel, or turned on and off by two buttons per channel __ Designed by Peter Jakab

HAM Radio BFO -  circuit diagram of beat frequency oscillator using BF494 and how to listen amateur radio communication on ordinary BC receiver.  __ 

HeNe Laser Transmitter/Receiver -  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.  LASERs are available from MWK industries.   __ Designed by Aaron Cake

Infrared Transmitter & Receiver Schematic Diagrams -  Schematic only, there is no circuit description given__
