Four times that!

For a fancy USB 3.1 connector.

Yep — 10 Gb/s USB 3.0 - https://www.digikey.ca/en/product-highlight/l/lemo/high-speed-data-transfer-usb-3-1-connectors

These sorts of connectors are almost impossible to connect to wires without a million dollar metrology lab.

Wait until you see what I'm doing with them. :)

The long screws are for a rack-mount annunciator that I've been building.

I used multiple stacked PCBs to hold the diffusors in place and to provide proper spacing for the LEDs, so I need long screws to hold everything together.

Here's a close-up view of how all the PCB layers are held together:

Exactly! And the second PCB is aluminium. :)

The spacers are good candidates for 3D printing, but my "CAD" skills are mostly from back when you did drafting on a drafting table.

I never did successfully make the transition to AutoCad, though I did have lots of fun programming with Constructive Solid Geometry back in the QuickDraw 3D days.

I really don't like subscription software models, and I'd have to buy a whole new computer just to be able to run it, so that's why I've avoided it... (last time I looked was when I needed a tool to do some sheet metal designs, but I ended up just drawing things out by hand and sent it off to the prototyping shop for them to convert into solidworks files.). Other than that, it looks like a very good piece of software.

I'd prefer something like openscad, but a little more mature.

The full dev environment for this project is set up and running again, and I'm able to build and install firmware updates.

That means that tomorrow I can work on adding in new code to allow each of the annunciator indicators to be individually controlled via SNON.

I've already written a VITA 40 library, so it should be pretty quick.

Software is done. Just need to do a little bit more clean-up of the code before I check it in.

TIL311s and the similar HP ones are lovely little displays!

I usually don't use sockets like these, and instead make PCBs for the front panel displays, but these are so old school, I just had to grab some.

@mos_8502

Me too! And they have plenty of unusual uses, too. :)

@arturo182 I've seen a bunch of samples with this process, and it is very impressive.

If you're interested in more details, there's a link to the WeChat discussion group at the bottom of the EasyEDA page describing how to use color silkscreen: https://prodocs.easyeda.com/cn/pcb/other-draw-colorful-silkscreen/index.html

There was an earthquake!

It showed up on the local seismograph:

Woah, that is pretty big for this area:

It's showing up on USGS now as a 4.6. Pretty deep. https://earthquake.usgs.gov/earthquakes/eventpage/us7000ljrn/dyfi/intensity

Canada's system now says it was a 4.9: https://earthquakescanada.nrcan.gc.ca/recent/2023/20231217.2323/index-en.php

"Felt on northern and central Vancouver Island, the Sunshine Coast and many parts of greater Vancouver."
