Links to electronic circuits, electronic schematics, designs for engineers, hobbyists, students & inventors:

RDS/RBDS Decoder with optional FM stereo receiver -  This project supports both RDS (Europe) and RBDS (USA)   Tuner FM band 88..108 MhZ (Europe and USA.)   You can choose between a 4x20 character LCD or a smaller graphical LCD to display data. __ Designed by Michel Bavin

Read 10 or More switches using only two I/O pins of a microcontroller -  02/28/13  EDN-Design Ideas Use a decoded counter to easily read one or multiple switch closures.  __ Circuit Design by Aruna Rubasinghe

Remote Control Encoder/Decoder with PIC16C620 & PIC12C508 -  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

Rotary Encoder Mates with Digital Potentiometer -  6-Mar-03 EDN-Design Ideas Buck IC boosts battery voltage for white LEDIn developing electronic systems, designers look for products or ideas that may benefit from the better performance, smaller size, lower cost, and improved reliability that an IC can offer.  Toward that end, the digital potentiometer emerged as an alternative to its mechanical counterpart, the mechanical potentiometer__ Circuit Design by Peter Khairolomour, Analog Devices, San Jose, CA

Satellite-dish command Decoder -  03/04/04  EDN-Design Ideas By decoding the commands sent by a direct-broadcast satellite receiver that uses the DISEQC (digital-satellite-equipment-control] protocol, you can troubleshoot the commands or simply listen in.  Eutelsat Corp (www.  eutelsat.  com] offers__ Circuit Design by Mark Giebler, Oakdale, MN

Selective Calling Decoders -  This isn't an Electronics Australia/Dick Smith project, but if you're interested in decoding and logging the selective calling (Selcall) and Automatic Number Indication (ANI) signals used in mobile radio communications networks, take a look at the Anzac Comms selcall decoder page.  I (Bob Barker) did the (Zilog) microcontroller software and the PCB layouts for them!  __ Designed by Bob Barker, not the TV Host

Sequential channel selector simplifies software -  01/04/01 EDN-Design Ideas An efficient but powerful circuit is useful for a variety of applications with limited I/O and for which you want to use one input to sequentially select a different output channel (Figure 1 ].  When the software changes the state__ Circuit Design by Alex Knight, Cummins Engine Co, Columbus, IN

Simple Circuit phototimer controls loA - D -  04/18/02 EDN-Design Ideas In industrial and home applications, the need sometimes exists for a device that, after activation by some physical effect, such as light, temperature, or sound, switches a load on for a predetermined time.  The load, such as a lamp, motor, solenoid, or heater, usually derives its power from the ac line__ Circuit Design by Abel Raynus, Armatron International, Melrose, MA

Simple Circuit Surround Sound Decoder -  This surround-sound decoder is based on the "Hafler" principle, first discovered by David Hafler sometime in the early 1970s.  The original idea was to connect a pair of speakers as shown in Figure 1, for use as the rear speakers in the surround setup __ Designed by Rod Elliott  ESP

Single printer-port pin acts as an encoder output -  06/07/01 EDN-Design Ideas Encoders and decoders are common elements in alarm, remote-control, and measurement systems.  However, most of these devices require many I/O lines when under microprocessor or PC control.  For example, the HT-12E encoder has eight__ Circuit Design by Deaign Idea by Haobin Dong, Huazhong University of Science and Technology, China

Surround Sound Decoder -  This surround-sound decoder is based on the "Hafler" principle, first discovered by David Hafler sometime in the early 1970s.  The original idea was to connect a pair of speakers as shown in Figure 1, for use as the rear speakers in the surround setup __ Designed by Rod Elliott  ESP

TDA1591 Stereo Decoder -  Stereo Decoder with TDA1591 IC.   __

Use your printer port as a high-current AM meter -  07/06/00 EDN-Design Ideas With a few inexpensive components and INT1Ch, you can turn the printer port of your PC into a high-current ammeter.   __ Circuit Design by K Suresh, Indira Gandhi Centre for Atomic Research, Kalpakkam, India

You've Got Mail -  08/19/99 EDN-Design Ideas Many e-mail programs provide a "beep" or a pop-up message box signaling the user that a new e-mail message has arrived.  If you are too far from the computer to hear the audible signal or if the monitor is turned off, then__ Circuit Design by Gary Kath and Craig Bishop, Scotch Plains, NJ
