Making your own gear is fun, and often centered around synths and effects... but Moritz Klein is here to show us how to make an active 8 channel audio mixer, which features some tasty diode distortion. The video goes from project start to finish, explaining every step of the way in an exceptionally clear and engaging way. You can buy some of Moritz's kits from Erica Synths: https://www.ericasynths.lv/shop/diy-kits-1/
 

Here's what he has to say about the audio mixer: 

 

In this episode, we're building a basic DIY mixer with a slight twist: built-in diode-based distortion. Probably a good project for beginners. If you want to build along, here's the bill of materials:

2x TL072 dual op-amp
2x 1N4148 diode
3x 100k potentiometer
1x 20k precision trimmer
8x 100k resistor
1x 27k resistor
3x 1k resistor

 

Here is an 8 channel version following this design, made by Something Physical
