Product Idea: USB Flash Drives

[dsimic]

Ah okay, well it would be good to communicate with your friend somehow at some point - especially if they are serious about helping with the project

Only time will tell how the things are going to work out.

Sounds fun! I've also had several unfortunate issues with my PineTab, so not particularly happy about that situation either. I'm currently looking to build my own laptop as I'm not particularly happy with the options out there.

Here's another issue I've been working on, and the fixes have been accepted by Manjaro ARM.  It was a small but rather nasty bug to flush out.

What I've accomplished so far is to get the TinyUSB's USB mass storage example compiled, although I haven't flashed it to a Teensy 4.1 yet.

That's excellent to hear. Please keep me up to date with how that goes and be sure to start putting stuff into a git repo if you're making changes.

Of course, I'll keep you updated and I'll try to upstream any changes I might end up making.

I had a ATtiny85(cheap digispark board) connected to a SD card a few years ago as part of a badusb fake-keyboard and mass storage experiment.  It wasn't fast but it worked.  I was using the Arduino IDE so that fit even with micronucleus bootloader loaded on the attiny.

Good to hear!  I assume that you used the SD card in 1-bit mode?
