Looks like I have to upgrade the challenge:
- delay the reveal to give more time because of new rules.
- introduce a new point notation system of 10 points.
- require at least 6 points to win.
- The winner is the one with the most points.

Check this change, will make the challenge more attractive and possible:

To self attest my honesty on this challenge and determine the winner transparently, here is the answer, encrypted for anyone to verify that I did not change it afterwards.

I will provide the key and info to decrypt as soon as we have a winner or in 5 days on Thursday May 22 at 1200 UTC.
No answer will be able to win after the release of the decryption infos. If we have no winner, well, that's sad, but will try another challenge later.

AHAHAHA well it could be a network indicator or a POE board, but since you didn't have protection and eth line it was a nice way to have a fried board, idk

Okay control engineer(to be) here... this circuit is likely to control something, and there is also relay. Are you switching on and off something? The green led must indicate sth too. Don't tell me that it was a manual reboot machine ahahahah

Here's what ChatGPT o3 and 4.5 came up with.

Since it was with medical stuff, I'd guess it was controlling some sort of alarm or siren, maybe based on biomedical data coming from the computer it was plugged into.

Nope. The meds tube is only a storage to keep it safe and dry. It just has the exact right size. It's not medical related.

or better still @nicom It seems to show an electronic component labeled 'fs 691c'. and based on my search, 'CV 691C' may refer to a ventilation valve used in vintage Chevrolet vehicles.

This is an FTDI USB to serial adapter board. It's used to convert USB signals to serial communication signals (like TTL UART) and vice-versa, which is crucial for interfacing computers with microcontrollers, embedded systems, and other devices that use serial communication. It allows for tasks like programming microcontrollers (e.g., Arduino), debugging, or simply communicating with serial devices.
