Runoffgroove - DIY Articles and Schematics

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.

Runoffgroove - DIY Articles and Schematics

Some Entertaining Projects are -

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.

Runoffgroove - DIY Articles and Schematics

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.

Homebrew Projects - Laboratory of Changpuak

The Electronics section of Changpuak maintained by a Teacher of  Thailand, Alexander C. Frank,  has calculation tools for electronic circuits as well as some electronic projects like power supplies, signal generators and curve tracers too .

Among others they also have Amplifier Design, Antenna and Filter Designer AF and RF and Basic Electronics Tutors.

Homebrew Projects - Laboratory of Changpuak

A Geiger–Müller tube consists of a tube filled with a low-pressure (~0.1 Atm) inert gas. (Helium, Neon, Argon,...). The GM-Tube has a coaxial shape, where the inner conductor (Anode) is biased with a high voltage (~500V) relative to the outer conductor (Cathode). The Tube has a window (left side) made of mica.

Homebrew Geiger Müller Counter

This GM-Counter is build on 2 PCB's. One is a standard high Voltage generating circuit, whilst the second is a Counter based on an ATMega16™ which also handles serial Communication with a host (Environmental Control).

This website conserves all those nifty little mini-projects (gadgets) which were developed to enhance the doctoral hats of our "fresh" doctors.

delabs Notes

Doctoral hat electronics - After seeing this section i am convinced that the next innovation will be "SmartHat". There is ample space in a cap for an Advanced Multimedia Gadget chip and all the works. Rush to the patent office !
