@MLE_Online Grab a megaphone, stand at a busy street corner, and yell at everyone to free themselves. Between the foil and the dripping dye it should be interesting...
@jarkman@MLE_Online (2) I assume everyone is capable of recognizing physical dangers (sharp edges) but beginners might need help with dangers not physically visible. Examples: Discharge high voltage capacitors. Remove pouch batteries so they are not punctured.
@jarkman@MLE_Online (1) If someone brought in their own thing to be repaired (and not just torn apart) the organizers need to somehow make that clear to other participants. We don't want their thing to be accidentally destroyed.
Counting from rollout of the first 747 in 1968, that's ~54 years of building 747s.
For perspective, a reminder that 1968 was only ~65 years after Wright Brothers' first flight.
A great run considering it was originally expected to be quickly overshadowed by supersonic aircraft.
There she goes!
The last 747 has left our Everett factory ahead of delivery to Atlas Air in early 2023. #QueenOfTheSkies

I've seen a lot of people asking "why does everyone think Twitter is doomed?"
As an SRE and sysadmin with 10+ years of industry experience, I wanted to write up a few scenarios that are real threats to the integrity of the bird site over the coming weeks.
A chaotic under-communicated layoff eliminated many of my closest colleagues and nobody we could talk to knew why. After months of management flailing at damage control I decided trust was gone forever and left.
Some at Twitter will hold out hope as I did, others won't wait.
@MLE_Online Request some pictures showing how much volume is available. Most people have a general idea of width and height of a dashboard gauge, but speaking for myself I have no idea how deep that space goes.
If it's not very deep, I guess you'd be constrained to those Sony Watchman tubes
@MLE_Online@jbg Here is my "single channel" proof of concept before Emily extended it to multiple channels. This proof of concept was in turn based on Emily's original experiment.

Exploring the guts of a dead Form 1+ laser resin printer. Looks like galvanometer commands are analog voltage level: oscilloscope plot on XY mode resembles laser beam path.
(Disclaimer: These effects are less flicker-y in real life than what's visible in these clips. It's a very challenging thing for me to record on video!)
If a delay is added between tachometer pulse and LED illumination, the visual shifts to a different location. Varying this delay over time can "rotate" the image at any speed independent of actual fan rotation speed, even backwards!
