Ugh So much metric. I’ve converted units for those (like me) who can’t relate to metric measurements that easily:
Fully fueled, it weighs [almost] [3.1 million pounds]. It will be capable of putting [142,000 pounds] into Low-Earth Orbit (for reference, the entire ISS weighs [about] [882,000 pounds]), [59,500 pounds] into Geosynchronous-Transfer Orbit, [37,500 pounds] into Mars-Transfer Orbit — or sending [7700 pounds] to Pluto (seven times the mass of the New Horizons spacecraft). It has a total of 27 first-stage engines generating over 5 million pounds of thrust at liftoff.

As cool as those outlets (and their supporting infrastructure) are, I do wonder what the ROI is on them, both from a monetary standpoint and an environmental standpoint. (All the extra support material has impact too.)

Could 3D print a case to hold the LEDs (and diffuse the light), and use said case as a sly way to slip a 90 degree USB OTG adapter in to talk with a cheap micro that could drive the LEDs.
Only thing left to manage is auto-launching a full-screen app, and locking it down so folks don’t poke around and break stuff. (The commercial offering we use also supports finding another open room based on what building/location you are in, and also provides a mechanism to report a device or hardware failure in the room, such as a bad Ethernet drop, misbehaving TV, or dead remote batteries.)
We run one of the more commercial solutions, and one of the nice features these units have is a nice red or green rear illumination (to the wall): If there’s a meeting going on, it’s red, otherwise green. Wouldn’t be too crazy to make it go yellow ~10-15 minutes before the next meeting if you were to roll your own though.

This whole money-first attitude isn’t helped by organizations that are publicly held either: Suddenly you have thousands of other people who now own a (typically tiny) piece of your organization, and the only thing they are interested in is getting more money back.

You could even modify your cane with lights and a button on the top (side? not sure what style it is) to turn the light on and off.

As you can see from the picture above, we have divided everything going into each box by weight and cost to make sure you receive a mixed box of different parts with different value.
I think that’s the key to this whole mess: Keeping the assortment evenly random and not just chaotic random. (I didn’t get in this time because I was a silly boy and forgot to set a reminder. Realized what I’d (not) done about 2 hours too late.)

A bit late perhaps, but I found it here: https://devhub.io/zh/repos/wmacevoy-ACZCPWM
Edit: Got ahead of myself there. The actual download link still points towards his GitHub repo, which is no longer present.

I’m with you on this: I’d love to see some proper PKI support on embedded architectures, but I think we’re still a generation or two away from seeing it really be supported natively. Perhaps the next iteration of the ESP line will have something for us. :-)
There is always the protected-subnet-with-a-gateway/proxy setup. Don’t allow any embedded/IoT product/project to talk directly with the Internet, but instead require them to use some local service to either encrypt all their traffic or to even be the final destination. (Why not just run your controller locally? Much faster response times, and no dependence on Internet connectivity for your fun toys to work. Then again not everybody runs a hyper-visor on a server in a basement closet…)
