PLANAR SPEAKER
ELECTRONOOBS Jan 08,2023
This is the PCB for this project and as you’ve noticed, this time I’m using a flexible PCB. It looks a bit strange but this is exactly what I need for today's project. We are making a planar speaker. Planar speaker headphones are quite expensive so making a homemade one would be great. In this project I’ll tell you what planar speakers are and the difference between these speakers and normal cone speakers, then I’ll show you what we need for the project, we design the PCB as we need it...

6-channel stereo speaker selector
Jayakody Dec 31,2022
This project is a DIY six-channel stereo speaker selector based on STC15W201 MCU. The purpose of this electronic switch is to share a pair of speakers between six stereo audio systems. This is an improved and low-cost version of the 6-channel speaker selector which we developed a few years ago.This new speaker selector uses STC15W201 MCU. This MCU is a low-cost 8051 MCU designed by STC micro. At the time of this writing, the STC15W201 can obtain for less than US$ 0.8. To drive the seven segments...

Huge Bluetooth Speaker
Arnov sharma Nov 21,2022
Hello everyone, How's it going?So here's something loud: a Bluetooth speaker made from scratch by reusing the body from an old project and speakers from an old home theater system.The goal here was to create a working speaker from reusing stuff, so I printed a top and bottom cover that hold the left-right speakers and subwoofer.I previously made a project that had a middle body portion made completely from PLA, it took more than 20 hours to print and was super huge.After a few changes I made to ...

Headphones amplifier
Antonio Oct 07,2022
This circuit was designed to build a headphone amplifier using two LM386 operational amplifiers. When turned on, a NE555 Timer is also powered, which controls a relay that allows you to activate the audio outputs after a few seconds in order to avoid noises when the operational amps are switched on. It can drive headphones and speakers up to a very high impedance and without distortion. It will certainly never be used at maximum volume as the amplifier power is 0.75w per channel, which is enough...

Automatically Turn Off the Power Strip of the Computer (monitor, Speakers, Etc.) When You Shut Down the Computer.
Maurizio Miscio Sep 25,2022
If you have a desktop computer at home, you will know better than me how boring it is to turn off the power strip of your computer every time we click on "shut down" to turn off monitors, speakers, any lights and so on.Since I went through this situation before this project, today we are going to see together how to build a relay module that keeps all the devices of the desk on until the computer is turned off (even after an update).To turn on the computer we have to press the button to bridge b...

Mini Guitar Amplifier Speaker
barita Apr 26,2022
In this project I want to make a mini amp/speaker for guitar.This can be very useful for those of you who use electric guitars that cannot produce sound directly (must be amplified by an amp).So you don't have to carry a big amp with you anywhere and don't have to worry about troublesome guitar cables.Just build a device like the one I made in this video, and just plug it into the akai output on your guitar.The circuit is very simple, already has an integrated clean/distortion feature.It only re...

Wireless Speaker PCB
Ardutronic Apr 07,2022
I love making my own PCBs, it gives me a lot of pleasure and I enjoy listening to music even more (my favourite genre is rap :)). On my desk there is always a lack of space for tools or electronic components, that's why I created a prototype of a tiny wireless speaker.The case is fully made of PCB, all electronic components are on top. I can listen to my favourite music on it thanks to the Bluetooth module and if I get bored with it, I turn on the radio to listen to the news. Using an encoder, I...
