Now introducing: #PDBrick!

1.7 kW worth of raw USB-C PD power.

24x USB-C ports.
4x 100W, 20x 65W.
(4x USB A, but we don't talk about those :P)

I never did a post of the project that @techbeard and I did last-minute before #CCCamp23, so here you go.
Build log in the thread below.

Front view of the finished #PDBrick prototype.
The 24 USB-C ports are prominently visible in cutouts in the raw copper PCB front.
A black plastic handle is mounted on top of the aluminum extrusion.

Back view. The back consists of another milled PCB that holds the Powercon True1 power input socket, the XT60 24V power output plug and a large OLED screen.

It mainly shows (a rough approximation) of the overall power draw and some internal stats.

The whole project was fuelled by initally finding really cheap DC-to-PD modules on #AliExpress (links below).

And for cheap but powerful power supplies, there was basically only one logical choice: Used server power supplies.
The #HP #DPS ones are pretty nice and modding-friendly.

JFF, I did a basic #CAD mockup of how the modules and PSUs could fit together.

It was too stupid and cheap to not give it a shot :P
