Here's a video of what that looks like. Starts with floating window to run my compile/upload command for Nerves (though that's not necessary, just wanted to show the floating window). Then `Space +d` for warnings in current file, and `Space + D` for warnings in the workspace

Booting into an IEx shell on Trellis 🌱
A huge thank you to @fhunleth.bsky.social for putting in a ton of time with debugging!

If you saw me last week at ElixirConf, you might have seen my Nerves-powered eink name badge
It can show a couple of static images and take a picture with the camera to display on the screen
Working on putting everything in a GitHub repo this week in case anyone wants to make one of their own!

Really excited to share this one - I arranged the PCB factory tour in China because I ordered the first production batch of Soleil boards there.
This clip shows me unboxing the boards in the shipping room of the factory. They turned out absolutely great, really impressed with the quality

Okay this was a really cool machine that I hadn't seen before. For certain through hole components, there is a machine which will dip the through hole legs into a small well of solder. It's better in some cases because it doesn't require tooling to create a mask for wave soldering

This one is called wave soldering, and it is used to solder through hole components (which have "legs" that poke through the PCB)
Basically, the PCB is loaded on a conveyor and slowly moves over a bath of melted solder. The legs drag through the liquid metal, and get soldered to exposed copper pads

New clip from my factory tour of a PCB assembly shop in China this past week - showing a pick and place (PNP) machine.
The toolhead on this machine has multiple vacuum nozzles which pick up the tiny components, move them to the correct spot on the PCB, then place and release them
