Ask HN: What was an interesting project you started and finished over a weekend?

this one, took me little time to figure out how to use wireshark, get data, input command with my phone...eventually the voltage regulator died a day after for overcurrent or dead chip. But it was fun. I don't have the motivation to undead the device unfortunatly.
- Take control of a LED controller, it's easy

The TXT records are based on the Bonjour Printing Spec [0] which list out which fields so it knows the type of the printer and it uses the SRV port to find the ipp port so it can contact the printer.
Further investigation using rvictl (iOS packet sniffing) showed the IPP traffic, which is really http API. It is via this API that iOS determines what paper is supported from what tray.
The path is then clear: create my own mDNS service that returns a printer on my own port, this IPP port acts as a reverse proxy to the real printer's IPP port, but it modifies the "media-col-ready" attribute to make iOS think A6 is loaded into the manual try.
It was extremely painful, but it was done: https://github.com/LittleLightLittleFire/fakeprinter
