Sam has some wonderful Audio and Video circuits. He is from Greece the land of Mythology and the Gods. These are Electronic Circuits and DIY Projects for the hobbyist.
Analog Synthesizer Do It Yourself - You have just discovered one of the coolest analog synth resources on the web. Check it out, build something cool, have fun.
Gainclone or chipamp is a type of audio amplifier made by do-it-yourselfers, or individuals interested in DIY audio. It is a design based on high-power integrated circuits, particularly the National Semiconductor Overture series.
Here are many Audio Effects and Music DIY electronics Articles with Schematics and idea behind the concept. Electronic Music Enthusiasts will find these useful for learning.
Mr. EQ - A simple, yet potent DIY equalizer. Schematic, PCB/perfboard layouts, and photos.
Little Gem - Two 9v battery-powered amps based on the LM386. Schematic and PCB/perfboard layouts.
Eighteen - The Marshall 18W adapted for use as a distortion stompbox. Schematic, PCB/perfboard layouts, and photos.
Tonemender - An ultra-flexible tonestack with clean boost. Schematic, photo, and PCB/perfboard layouts.
Thor - The legendary Marshall 100W Super Lead adapted for use as a distortion stompbox. Schematic and PCB layout.
The Thunderchief project, released in March 2004, was the first runoffgroove.com circuit that was developed using the tubes-to-FETs process. Enlightened and inspired by Doug Hammond's excellent Meteor circuit, we used the same approach in an effort to capture some of the legendary magic of the Marshall Super Lead. The circuit's performance pleased us, but there were issues.
Splitter-Blend - Dual parallel buffered effect loops with blend control. Schematic and perfboard/PCB layouts.
Professor Tweed - The Fender Princeton adapted for use as a distortion stompbox. Schematic, PCB/perfboard layouts, and photos.
A Tutorial describes fundamental ideas of electro-technology and the general amplifier and audio technology. The test equipment gallery shows measuring instruments - older, historical and partly new.
Obsolete Test Equipment Gallery
The gallery shows measuring technique, with which electronics are developed. Some are special and classic devices, which are still in use and some already represent a historical value. Many of these devices have special functions, which are very popular. The side does not intend to show newest test equipment from the portfolio of the manufacturers (some devices excluded).
