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.

You need to install an executable on your machine.

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.

Why is that expensive ? I’m genuinely asking. Considering the time / labor / troubleshooting etc to put something like this together yourself , plus cost of materials ?

In my mind , the labor rate for a professional is a minimum of 1.00 per minute. This package would be essentially one hour of billable time at the (lowest) rate a professional would bill themselves out at.

Presuming it’s FLO or at least some kind of simple AT command set and meets all the other requirements, I’m really struggling to understand how it’s expensive ?

I mean , sure if you need 10k of them or something.

Are people really this price sensitive ?

It used to be just simple scale. Kindle didn’t use them, so nobody made them. A chicken and egg problem.

Soldered.com makes some really nice eInk dev boards, including one with a 5.8" 7-color display: https://soldered.com/categories/inkplate/color-e-paper/

+1! I love their Inkplate 2 - quite affordable, color eink, wifi (via esp32). Absolutely super fun and affordable.

Well, if you don't buy it, then you won't build anything for sure. If you have a drawer full of little components, the time may come to actually use it.

Yep it starts being really fun when you can go directly from an idea to making it, because you already have the components on hand from previous projects/hoarding.

This applies to all different fixes and hobbies so well. Just this afternoon my old Miata had the power steering 'cooling lines' finally rust through. Once I got home, I rummaged in my toolbox for old car tubing, rummaged elsewhere to find some small hose clamps and spent at most an hour cutting off the rusty parts, reattaching with line and clamps, refilling, and cleaning things back up. (luckily the cooling loop is on the low pressure side of things, so if it moves fluid a -> b and is kinda sealed up, it's good to go)

Point is: Having the drawers of 'I'll save this just in case!' in all hobbies does in fact come in handy. I find this especially true when some sort of project requires 'yet another adapter' to convert thing a to thing b. Project either goes through or it doesn't, but later on when trying to attack something else, having that little drawer full of weird but useful cables and adapters within living room walking distance sure feels rewarding.

> 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…

I like those monitors for finding weird, surprising (to me anyway) things - like when I charge my Framework laptop from a USB port on my work laptop (because I don’t have another power socket handy to plug them both into the wall) the Framework laptop draws twice as much power when it’s asleep as when it’s awake. The opposite way around to what I need! From memory, 5W when running (not enough to prevent the battery s…

I love my AMD framework, and I don't think my numbers are as terrible as yours (7-9 watts just chilling watts idle. However, the 'sleep' use is still, bad. I hunch it's a linux thing. I don't even bother, I just turn the thing off.

“The project” - your creative drive to “do a project with this device” is completely fulfilled by purchasing. It’s a strange thing but there’s a direct line from creative desire to buying then not doing. This is why I have so much electronics junk it’s all projects that I “completed” when I hit the buy button on Aliexpress.

I'm trying to channel my tinkering drive into software projects. Somehow these usually to get at least to the "hello world" level. Also, when left unfinished, they don't occupy the precious 3D space around me. Also I need to sell an oscilloscope and a bench power supply :)

Heh. And here I’m being tempted to purchase a soldering iron again…

I feel like the winning move here would be to put the screen on a ball joint or hinge to give more options than just “face forward” v. “face backward”.

Probably can’t do that for $2.

Then just sell it as the Deluxe™ version for $9.99, problem solved :)
