This is a model circuit that can control the speed and the direction of a dc motor without the h-bridge ( it's an alternative to h-bridge ).
This is certainly the cheapest and simplest Internet radio that you can make yourself if you have minimal knowledge in the field of electron
I'm trying to resurrect my aunt's home cinema DVD player.
I'm building working model of differential pressure airflow measure device with analog sensor, instrumentation amplifier and Arduino.
The automated bird repeller system seeks to fend off birds from crop fields to minimise damage and maximise crop output!
This is the simplest amplifier works on the principle of band pass filter and no external power supply is needed.
A 3D printed Arduino Nano based synthesizer that produces a wide range of amazing sounds generated using the FM synthesis technique.
A class D audio amplifier based around a TPA3255 board with features that include preamps as well as balanced and unbalanced inputs.
Building my first tube amplifier, on a tight budget.

The Vox AD60VT and AD120VT provide a huge range of amp models and effects. Emulating their foot controllers enables live Midi Control.
4 channel audio circuit using 2 channels at input. A small and gain booster circuit with Operational amplifier.
It is 5.1 channel amplifier board consisting of dedicated high fidelity IC for subwoofer and speakers. Let's build one as party boom box
Most remote controls look pretty much the same, they serve a purpose. They could look good too.
Learn about some basic transistor circuits, we will look at the BD139 & BD140 Power transistor pair and look at circuits for Arduino/ESP8266
A classical analog logarithmic converter is simulated with LTspice with emphasis with drift compensation in temperature with a PTS RTD
Using this preamplifier you can increase overall gain, tune frequency accordingly, enable dolby and drive one more channel for subwoofer.
