ECH83 Guitar Preamplifier with Tone Control on 12V DC
Pavleski Nov 17,2023
 A vacuum tube preamplifier is typically used to amplify the signal from a microphone, musical instrument, or other audio source before it is sent to a power amplifier or recording device. Compared to solid-state preamps, vacuum tube preamps are known for their warm, natural sound and ability to add harmonics and distortion that can enhance the perceived "musicality" of the audio signal. They also have a unique "saturation" effect that can add a pleasing "tube warmth" to the sound. &nb...

A compact antenna analyser with graphic colour display for 1-30 mHz
Bochkarev Nov 17,2023
A simple antenna analyzer is a helpful gadget which will tell us about the frequencies to which a piece of wire will resonate on. This is very useful in conjunction with a simple tuner to adjust the antenna for an optimum VSWR (voltage standing waves ratio). Usually, a good commercial antenna analyzer is an expensive device which we use once in a while. Here is a simple project which will give a rough estimation of VSWR and resonant frequencies of a random piece of wires, antennas and lc ne...

Mini RC Remote
Fikru Nov 12,2023
An RC Remotes is now the most widely used device for diy projects. There are a bunch of different types of RC Remote. The RC remote I made is a DIY mini RC remote which used to control drones, rc cars, or other projects which needs transmitter and receiver. This project is based on Atmega328P IC. It can control up to 8 digital channels which is best.
