@RoganDawes@infosec.exchange They can be yes! And some designs actually want that! i.e. CMOS camera sensors.
I'm not sure if they'll always be clear like this, but it's makes them better to show off. Easy enough to paint them if needed.

@mole99@fosstodon.org I don't have a bringup PCB designed. Very un-organised on my end. I'm thinking I'll bodge-wire a SPI FLASH to see if I can get to Blinky this weekend. ✨
First samples on the first run from wafer.space!
There is a disclaimer with these parts, that only ~80% are fully bonded successfully.
This could be marketed as a feature, an air gapped solution using state of the art wireless bond wires. 😜
Fresh and custom silicon day! 😍
This is a multicore riscv soc design based on the serv processor core.
Based on GF180MCU PDK, and fabricated through wafer.space 🚀
I like that the COB is done with clear epoxy on these samples, rather than just a black blob

@alexanderdyas@mindly.social these were available for a time from here: https://hannio.org/en/produkt/1x7-flipdot-stripe-10mm-yellow/

@Kartoffel@hsnl.social Eventually I would like to, it's just a pair of 74lvc595's and 7 low cost h-bridge drivers.

Got a little carried away in inkscape on the silkscreen for this ESP32-C3 based controller board for controlling some flipdot display modules.
Using this plugin from PCM, which makes the KiCad to blender process super easy: https://github.com/30350n/pcb2blender
