Definitely. I assume the actual cost for the cable is <10$, but engineering work gets very expensive very fast if you’re small scale.
I’m interested in something - say you got an order for 1 million units, what’s the price per unit you could offer?
Edit: just looked at the DIY option - seems right now you’re just using off the shelf parts, which is fine. Clever use of them, even. Main part seems to be ‘present usb device - once the usb device gets removed, lock down the PC’. So, you specifically just need some usb device with a cord that attaches magnetically - and securely enough that it doesn’t disconnect randomly, with some mechanical way to fix it to yourself. So yeah, at million scale, seems you could definitely sell it for 10 bucks a piece.
Project hail Mary was cool in the fact that it was just so… Different. Won’t say too much to avoid spoilers, but I think it’ll tick your boxes.
