After some months of use and adding some more power hungry modules I decided to overhaul the whole thing.

• I made some PSU a while back, using a QUI DC/DC converter.
• There's those handy USB-PD module from China which are capable of deliver 20V and a reasonable current if connected to proper USB-PD PSU.
• If I mount the rails a bit different, I'm able to squeeze in a 1U row as well.

Unfortunately one of those PSU had some issues. so I made new ones, this time directly using ±12V DC output modules instead the ±15V DC and 7812/7912 I had before. Just more caps. My rack is less LOOK MOM NO COMPUTER and LOOK MOM A BEOWULF CLUSTER OR ARMS anyway.

During the build time, I found there's no USB-PD eurorack power module available easily. That's probably my next project, since the ability to power your rack from a beefy powerbank when ambient DAW less jamming in the woods seems pretty handy to me, and today most laptops a USB-PD powered anyway.
