What I want doesn't exist (yet), so I will create it ⚡️

btw if you buy a device with a wireless component to it (bluetooth/wifi/etc), you can put the FCCID into fccid.io and (probably) find internal photos

The photo quality likely won't be good enough to get the component numbers but it's kind of a neat exercise to see what electronic innards looks like

here's a walkthrough of a similar-ish process on another product: jaimelightfoot.com/blog/led-the...

Starting with just camera photos and online research, then getting into needing a multimeter, and more specialized equipment from there
LED Therapy: Intro to Hardware Hacking Using the Neutrogena Light Therapy Mask
In the pre-Covid BeforeTime, my friend told me about this LED face mask she bought. The idea is that it lights up red and blue LEDs to treat your skin (I don’t know how effective it is, but that’s not...

Oooh that game looks fun! I haven't played it before

Definitely worth trying out if you're up for it! and if you don't mind losing $X if you accidentally brick the device

you might already know the term "cyberdeck" but there's communities doing really cool similar projects under that term

If you do decide to try modifying this Merriam-Webster dictionary, I'm happy to help out, reverse engineering stuff like this is sorta my day job 🙂

if you want to do a similar project anyway, it would probably be easier to start from scratch (Adafruit and Sparkfruit have great software and hardware guides to go with their products) and try to squeeze the parts into an existing casing or 3D print something

If you're lucky that's finding part numbers on the components and matching it to datasheets/documentation to write new software, and have all of the hardware (voltage levels etc) be compatible.

If you aren't lucky it's a software reverse engineering effort and/or some hardware work

I think it'd be a lot of messing around. You'd have to put some reverse engineering effort into figuring out which protocol is in use (I2C/SPI/etc) and the message content, for both the screen and keyboard.

kinda love "Judy 0-Day" as a hacker name, lol

sorry if this weird coming from an internet rando, but I recently went through this with my own senior pup and just wanted to say I'm sorry, it's a terrible thing to go through 😞 she looks like a total sweetheart

I think they use `U+200B` but I suppose you could do it with other non-visible characters too (and then look at it with a hex editor)

It's not really my area but there's even a way to encode text messages into documents via whitespace, "Steganographic Nature Of Whitespace": darkside.com.au/snow

Tesla/etc have caught people in the past using "whitespace watermarking", with variation in how many spaces are after a given period. There's a non-visible version of this too, with zero-width characters

social engineering people into following security policy but it's just me being Midwest Nice

on the other hand, shitty cybersecurity messaging gives me a huge advantage as a consultant

I show up and treat people with a normal level of social grace and that's enough to make them think I'm the nicest security person they've ever met (all my requests get implemented too)
