- I would like to shout out to the Parkside engineers for their careful and responsible implementation of USB-C standards. I think this is what the industry would call a “fire hazard”.
- But Peter, the USB-C spec allows 20V. Yeah, no. It allows the device to *request* that much. If no signalling is made, it must not deliver more than 1V (!) and there's a simple resistor based signal to request 5V. Anything above 5 requires USB-C protocol negotiation.
- I wanted to design an over-voltage protection mechanism for the Arks. Picked out the components, but didn't want to design the wiring schema manually. Asked ChatGPT to do it. Ugh, tons of text, extra components, etc. Probably works, but so hard to digest. Asked Gemini... damn🤯
- Now, there's nothing hard about that diagram: read the spec, calculate the numbers, put it all together. But it's a wonderful double check for me: I *think* I know how it should look like. Having someone/something else get to the same conclusion means I didn't miss anything.
- All assembled :)
- My goal with the Dark Bio Ark was to protect sensitive data from unintended access… but seems with all the AI agent crap everyone is doing, that “Ark” name starts to be a premonition instead of an accidental choice. 🥲
