This is a simple JFET input buffer that goes into a clean boost based on the old Electro-Harmonix LPB-1 Linear Power Boost. The guitar input is buffered and then split off to four input points. These input points can then go on to various other modules in the box. A bog-standard Fuzz Face. The only mod is that I`m using NPN MPSA18 transistors and

the traditional fixed bias resistor has been turned into a pot. I love the snarly nastiness of the Fuzz Face so it would have been crazy not to included it in a box centered around fuzz. If I had to dedicate the work behind the Armageddon Processor to any single person, it would probably be Christian/Hemmo. He has one of the most offbeat DIY sites. It hasn`t been updated in a long time, and it is ugly as hell as sites go, but his little snippets have gone a long way. The Black Fuzz is based on his single and double transistor designs. I put two of them back to back and added a filter. Tim Escobedo `s Circuit Snippets is one of the crown jewels of the DIY schematics world. He has so many designs that are different and thought-provoking. One of those is the PWM, a fuzz that is based on a Schmitt trigger. I modified this design to cascade an additional gate and added a filter control. Lovely. Another nod to hemmo/christian here. He had a couple of circuits based on the LM567 chip. This bizarred device was designed to decode touch-tone frequencies on telephones. His hackage opened my eyes to this msytical device and I spent many hours at the breadboard trying all the possible permutations of what the 567 can do. I ended up with a modifier that can go from a choppy tremolo to a nasty ring mod at the twist of a dial. Like an idiot alchemist trying to turn lead into gold, I`ve spent a lot of time trying to get faux synthesizer...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
