Portable 4sum Audio Mixer

SyntherJack has been in touch to tell us that, based on his synth meets and home DIY experience he has designed a simple, portable audio mixer - 4sum. He believes that it is a great companion for mini synths, like Monotrons and Volcas and also makes an excellent first audio-related DIY project.

Main features:

• 4 mono inputs / 1 stereo (double mono) output with separated volume controls
• very long runtime (average 100 h)
• small factor
• beginner friendly build

Here's the mixer being use in a Monotron Duo/Delay jam...
