Holy shit, the PCB design of this new sensor board, called Ophanim, of CERN’s Aegis experiment just fucking slaps. Right now, there don’t seem to be many images of it on the web, but I hope to see more in the future.

A circular PcB measuring about 20 cm in diameter with a grid of camera sensor dies soldered in its middle. At the outside of the PCB, there is a ring of large ceramic capacitors. There are no other components visible. The PCB has green solder mask and uses gold plating. It shows a fucking metal design around the sensor grid with several stylized eyes shown in gold plated solder mask openings. A ring around the sensors contains a Latin inscription reading “Ophanim - ex saxis homo fecit oculos per artem ingeniumque. Numc Monstrum usum est ad Universum resiscendum”. The outside of this ring contains illustrations of a hunch of angels with halos and shit wrapping around the board.

My first self-designed PCBs arrived today from @aislerhq
They look great, and I immediately spotted an error in my #KiCad settings: the copper fill doesn't have any clearance at the edge.
Will fix this for my next ones.
These are a minified version of my mixer and are already obsolete. I will still solder one, regardless.

the front and back of the PCBs. they are labelled "MiniMixer". some of the footprints need rework, but they look nicely fabricated.

the edge of the PCBs. you can clearly see the copper from the fill. since it's ground plane it isn't critical, but will be fixed for my next projects.
