Telephone Headset Adaptor -  Keep your hands free with this simple low-cost project.  It can be used with any phone that uses RJ11 modular plugs and sockets. __ SiliconChip

Telephone Headset Amplifier -  This circuit goes between a telephone and a headset.  The project has a headset cord and plug (cut from a cheap cell phone headset) on the input and a suitable jack on the output.  The speaker signal passes through this circuit, but the microphone signal is __ Designed by Andrew R. Morris

Telephone FM Transmitter -  This FM transmitter attaches in series to one of your phone lines.  When there is a signal on the line (that is, when you pick up the handset) the circuit will transmit the conversation.  In particular it will radiate from the phone line itself.  It is a passive device, there is __ Designed by Electronics DIY

TDA2822 Stereo Audio Amplifier -  TDA2822 is a low power stereo Op Amplifier used in Walkman players and Hearing aids.  It can give 250 mW output.  TDA2822 is an ideal Op amp for low output applications.  It is a good choice as a preamplifier in stereo high power amplifier circuits.  It has two inputs and two outputs which can deliver 250 milli watts output power. __ Designed by D Mohankumar

The Big-E Stereo Parabolic Microphone -  This device is a stereo amplifier for a high sensitivity stereo parabolic microphone.  It can be used for listening to distant sounds.  Typical parabolic microphones are monophonic, this unit has a stereo audio path that helps produce more realistic sounding audio.  The Big-E can be used with headphones or as an audio source for a stereo recorder.  It can be plugged directly into a computer sound card's aux input. __ Designed by G. Forrest Cook January 1, 2005

The JV80 Loudspeaker SystE - M -  Over the years, we have published a number of do-it-yourself speakers but the JV60 has easily been the most popular and long-lived.   Now there is this new system, still using Vifa speakers but with bigger (8-inch) woofers and a teensy little Vifa D26 dome tweeter.  In fact the tweeter looks so small and insubstantial that you'd wonder how it could possibly stay with the pace set by the two big woofers.  Yet it does it easily, due to some fancy technology which we'll get to in a moment. __ Phil Routley, SiliconChip

TwinTen Stereo Amplifier -  Build this gutsy little amplifier for your Discman, MP3 player or games machine __ SiliconChip

Two-Way Stereo Headphone Adaptor -  Do you have a stereo amplifier without a headphone socket but want to listen to your music via headphones? If so, this versatile Stereo Headphone Adaptor will do the job.  It connects between your amplifier and loudspeakers, has several operating modes and features two output sockets with individual volume controls. __ SiliconChip

Two Line Output Combiner -  Sometimes there is need to combine the output of two line level audio sources to be fed to one input.  A standard way in professional audio is to use a mixing desk, but on home audio system you might want to look for a simpler and less expensive alternative.  Some people have suggested of combining two audio outputs with an "Y-adapter" which is ment to split one output.  Those adapters are just one male connector and two feamle connector directly wired to each other in the followin way: __ Designed by Tomi Engdahl

Ultra-LD 2x100W Stereo Amplifier Pt.1 -  This no-holds-barred audio amplifier is rated at 100W RMS per channel and has very low distortion. __ SiliconChip

Wireless IR Headphone RX-TX CD4 046 -  Schematic only __ Designed by va3iul

Voltage Controlled Panner -  pans audio left and right __ Designed by G. Forrest Cook

Wireless PLL Stereo FM TX with LCD -  Now you can use your MP3 Player to listen your favorite tunes through any FM stereo receiver.  Wireless FM transmitter wirelessly connects portable music players to your car or home stereo quickly and easily.  Just plug the FM Transmitter into the headphone jack of your MP3 or any audio source including iPOD, PDA, CD Player, Cassette player or connect it to your PC or laptop computer.  Tune your card stereo or receiver to the clearest FM frequency, and enjoy your digital music with full sound and convenience.
