Hammonator AO-14 Organ to Guitar Amp Conversion -  18 watt tube amp with reverb; adds pitch-shifting vibrato and tremolo __ Designed by G. Forrest Cook

Headphone Monitor Amp -  Computer soundcards typically have line level and speaker level outputs.  Neither of those is usually nott very suitable for driving headphones: If you connect the headphones to the line level output you will usally loose tha bass frequencies because of small coupling capacitors.  Line output circuitry might be overloaded because of too low input impedance and this can cause distortion __ Designed by John Simonton

Homebuilt MP3 Player -  Welcome to Frank’s website, home of the do-it-yourself MP3 player, a DDS based signal generator, and more.  For the MP3 player pages, including source code & schematics, please click on the photo below.  Or use the menu on the left.   __ Designed by © © 2014 Frank Van Hooft

Infinite melody for music synthesizers -  The name of this module is a play on its function.  Put simply, it generates a series of semi-random or themed stepped control voltages, or if you prefer, white and pink control voltages.  The pink function is probably better known as 1/f, and thus the name of "1l/lfinite melody". __ Designed by Ken Stone

Infrared Theremin Musical Instrument -  The constituents of the electronic circuitry in the invention are represented in the following figure, "Block Diagram of the Optical Theremin.  " Note that the interconnecting lines and arrows in the figure are representative of the signal process sequence, and not representative of specific electrical connections __ Designed by Arthur Harrison

LED Musicolour: Light Up Your Music, Pt.1 -  Now you can have a kaleidoscope of colour which continually changes in time to music.  This consists of 16 strings of LEDs which are individually controlled by 16 frequency bands.  Louder signals in each of those bands means that the respective LED string will be brighter.  Use it for a Christmas light show, a disco or just for fun when playing music.__ SiliconChip

LED Musicolour: Light Up Your Music, Pt.2 -  The new LED Musicolour makes building a spectacular light and music show easier than ever.  In this second and final instalment, we explain how to build and test the unit and also detail how you can control it.__ SiliconChip

Light Alarm with LDR -  This musical light alarm circuit is very simple, uses only 7 components, a LDR and a 3.6 V battery or 3 x 1.2 volts rechargeable batteries.  The well-known UM66 is used as the sound generator and will give a pleasent wake up alarm.  As you probably know the LDR is a light dependent resistor.  Normally the resistance of an LDR is __ Designed by Popescu Marian

Lil' Tiger AO-43 Organ to Guitar Amp Conversion -  with reverb, pitch-shifting vibrato and tremolo __ Designed by G. Forrest Cook

Liquidator Tube Phaser/Chorus Effect -  This project involves the conversion of a Hammond AO-47 organ vibrato unit into a 4 phase guitar/music phaser/chorus box.  The individual phase signals can be mixed for a wide variety of sounds.  The Liquidator name comes from the liquidy sounds that the device creates, it wiggles the audio all around.  Used Hammond vibrato units can often be purchased for little money on eBay and provide the majority of the circuitry for this device.  The Hammond AO-41 box can also be used for this project, it has a similar phaser circuit and one extra 7 pin tube socket.  Here is the Original Hammond AO-47 Schematic for reference. __ Designed by G. Forrest Cook

Little Guitar Amp -  I built this little guitar amp for my brother, Rich, a while back.  Originally it was sort of a Fender "Champ" copy with a 12AX7 front end.  I recently converted it to use a single EF86 pentode, instead.  I like it much better this way.  The amp chassis fits into a small maple open-back box with a single 10" speaker.  Rich built the box __ Designed by Bob Danielak

Low pass filter for subwoofer -  The acoustic spectrum is extended by very low frequencies 20Iz and reaches as the 20000Iz in high frequencies.  In the low frequencies is degraded the sense of direction.  This reason us leads to the utilization speaker for the attribution of very low frequencies.  The manufacture that to you we propose distinguishes these frequencies, in order to him we lead to the corresponding amplifier.  The acoustic filters are met in various points in the sound systems.
