Show HN: Building Electret Mic Preamp Open sourced

hackaday.io

5 points by nativeforks 2 days ago

I designed and built a studio-quality electret microphone preamp focused on low noise, high gain, and clean audio capture using easily available components.

This is an original design — it does not follow TI, Analog Devices, or other common application schematics.

The circuit was tested and verified in LTspice before building. All schematics, design rationale, and build instructions are open-sourced for anyone to replicate or improve.

Here's a short demo of the audio performance: https://youtu.be/RZR_PrxcBBU?si=9gN_5yx09bwNFjba

I spent over a month researching, simulating, and testing before publishing. Feedback is welcome!

Impressive! Good work. I love it that you made it open source, and that makes me want to buy it even more. How can I buy a fully assembled product from you and make a donation in the process?

    I've made the process easy for others to mimic this. But I don't have a budget to make CUSTOM PCB's and sell it. Thanks for your appreciation :)
