Lately, it seems like you can’t scroll through social media without seeing AI-generated content everywhere. For the most part, I don’t mind it. AI is an incredibly powerful tool for writing, brainstorming, and creating stunning digital art.
But recently, I’ve noticed a troubling new trend popping up in the maker and electronics communities: AI-generated circuit schematics. And frankly, it’s alarming.
build an Ai Speaker for less than $20
Ai is everywhere so why not make use of it for our next project? In this project I build an Ai assistant speaker that you can talk to and ask anything. Here is a simple diy ai speaker chatbot that is easy to build.

A power sequencer is useful for audio systems where you can power up each equipment one at a time in sequence. This will prevent pop sound on the speaker during powering up or down. Basically the power sequence is from input to output when powering up and output to input when powering down.\

I recently got to work with 64×64 RGB matrix and got into some issue. For some reason it only displays half of the screen. After some research, I figured it is just a simple problem.

Lithium iron phosphate (LiFePO4 or LFP) batteries have several advantages over lead acid batteries when it comes to use on electric bicycles, or e-bikes.

One of the problem for low budget band online streaming is the mixing part. The biggest challenge is getting the mix right. Why is it hard? Guitar and other instruments have their own amplifier so when you are doing the mix, you would likely decrease the level of these instruments to the main mix. If you are feeding the main mix into your online live feed, chances are these instruments are too silent on the main mix.
This circuit can be use as a headphone amp mixer with built in DI box so you can directly feed the output into the mixer. There are 2 volume knobs, one knob is used for your instrument volume and the other knob can be used as a monitor level feed from the mixer.
