The mixer is really handy for DI`ing guitars and basses into soundcards or other mixers and making use of channels on mixes that do not have mike in`s, it comes in handy for one or two guitarists that want to sing and play through one guitar amplifier as well. The printed circuit board will not be exactly the same as the one in the pictures, it wi

ll be a bit better it has pots mounted on the broad in the same way as they are mounted on the board for the compressor. A second board design with a slightly different arrangement of the plots to suit lower impedances and separate direct outputs for soundcards will be included. The difference between the two arrangements in respect to specifications is unnoticeable. The components on the first board may be rearranged and tracks broken to form the circuit provided by the second board or the board that best suits your application can be chosen. If enough interest is expressed in this project there maybe a ready-made PCB board available through this website. The bias voltage for all of the opamps is derived from a voltage divider consisting of two 10K resistors that provide a mid voltage point, this voltage is then amplified through an opamp to lower noise introduced by the resistors, the output of this opamp is the bias input for the other opamps. If you are going to be using the same supply voltage all of the time then noise can be lowered a little more by replacing one of the resistors in the voltage divider with a zener diode, chose a zener that is close to half the supply voltage.

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.....
