How did you do it OP? Built out of modern components or old circuits or a mixture? Very interesting, good post. I heard they’re putting wifi chips or receivers in everything nowadays, for example the voting booths that were supposed to be stand alone were all found to have wifi or cell transmitters in them. I don’t know anything about this stuff but I’d figure anything hardware that’s modern would be able to be tapped into on some rudimentary level. I second that users advice that said build a faraday cage around it

I’m sure you know this as well but for anyone else, memory sticks can catch and upload viruses discreetly which depending on their function could still cause issues for a stand alone unit

Memory sticks can catch viruses so there’s still a need to be cautious
