The coffee machine in our office is controlled by blockchain NFTs and a Raspberry Pi: Once authenticated, an owner of the NFT can select their coffee type on their phone which then signals the Raspberry Pi to make whatever coffee type was selected by jumping the contacts that used to be pressed by the machine's buttons (which have been removed). It's a cool gimmick, fun to show off to visitors, gives us a nice record…

Does it record on the blockchain who took the last cup of coffee and didn't make more?

Everyone in every office would pay good money for that.

The best use I have so far is for a local TV station have the Pi using a LAMP stack to:

a) a Pubic Service Announcement slideshow it autoboots into chrome and hooks in composite NTSC. Can be remotely managed, etc.

b) It also serves the station's website which previews the slideshow in a frame, or has a page showing all the slides.

Experience: very resilient just cycle power when problems... but learned the SD card is way too sensitive for power cycling - so now has an external HDD for better recovery.

Plan to work on one for data collection/receipt for a local recycler, that one will likely use Python with a touchscreen to collect signatures.

This is a big disruption to the POS/terminal market as it gives a very powerful/flexible platform that can be developed/deployed inexpensively, and parts can be sourced easily when HW problems occur.

Four things: 1. Pihole to ad block ads (useful for phone browsing) https://pi-hole.net/ 2. Custom Weather conditions dashboard, using Dark Sky's API I'd love to replace the weather dashboard with one of my integrated work / personal calendars so I could see what meetings I have each day but work won't expose that data, claims it's a security risk. 3.

A friend of mine is a big Mets fan with a home bar; I helped him build a sign that showed the countdown clock for the Willets Point subway stop for that room, which went nicely with the beer signs and other sports memorabilia he & his dad had been collecting for decades.

I also built a FE that scrapes bus/train/light rail arrival data from NJTransit's website (they don't have an API, but they provide some JSON in their web app responses).

We have over 2000 deployed over Europe in locksmiths, providing a form of key service to the public. Challenges include not DDoSIng our APIs, getting a correct configuration to not nuke SD cards, and ensure that a bad firmware push doesn't knock the network offline.

Any links? I’d love to know more.

Sure ! https://parklink.asia/ https://rebadge.eu/

We've got a custom PCB which controls the touchscreen and prehipherals (LF and HF RFID readers), placed in a custom, tough ABS case (locksmiths are full of metal filings, which don't play nicely with electronics...)

https://pi-hole.net . Just installed, very happy so far.

How do you deal with it breaking things like Amazon-based UI(Fire, Mobile shopping etc...)?

So far I have not found anything broken yet. I think I would go for a whitelist in that case.
