Started off on a techie adventure with an RP2040 DVI board from Adafruit, aiming to get the pico-zxspectrum going. Things started acting haywire once the USB hub got involved, ending in a complete shutdown, intuitive diagnosis showed the power pin was a ghost town! After pin-pointing (and removing) the dead IC, I performed a delicate soldering operation to bless it with a new 3V3 regulator.

Then, with a string of terminal commands, I was able to set it up as an iBeacon broadcasting a specific UUID.
