E-waste prevention is hella important. It's a tough situation though. I think for a board that goes out in the public, even at a prototyping level, it's important to know the chip you have is not tampered with. I once wanted to make a little people counter at a university campus with an ESP8266. I simply couldn't make sure it's resilient against some CS students poking at it.
- yonatan8070 1y agoLet's say the chip was lockable, what would prevent someone from using a bit of hot air and flux from just swapping out your chip with whatever?
- saidinesh5 1y agoThe firmware that's missing on that new chip
- bpye 1y agoThat's why you force a full erase to clear the non programmable bit?
- user32489318 1y agoIt takes little skill, 15USD soldering iron to solder 4-5 through holes wires, connect 10 usd programmer and flash a new firmware. Investing in a (de)soldering station, with the risk of pulling all the neighboring components, breadboard/something to plugin your new controller or memory into for programming and what not? I’m not sure if I’d go through that trouble
- alex7o 1y agoYes, but this I think is a bit sad. Once you have proper hard to crack security a smart kid from CS won't find it hidden decide to hack it and write blog post about it how he has done it. As long as it is not something dangerous sometimes having less security is better
- moffkalast 1y agoSounds like you're trying to deprive CS students of their practical education :P
