Description

What’s one to do when you want to play a DJ set but you don’t have a power point?

I posted a build writeup of an 8U mini rack for a solar powered car amplifier and Pioneer FLX-10 (DJ decks) power supply: https://2700kelvin.house/2025/10/a-solar-powered-audio-mini-rack/

I’m no electrical engineer – I'd welcome any constructive feedback or ideas!
