I used mine as a dlna server and file server, but I was constantly having to restart it or delete the database to get it to pick up new files I had recently dragged on to it. Has anyone been able to use one successfully for serving media?
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 of who is making coffee (since each NFT's owner is unique and trackable), limits users to those with the NFT without us having to build usernames/passwords, and is also how I make my coffee each afternoon.
Unpowered in a drawer.
1. Media player connected to projector running RasPlex - this software is outdated enough and buffers on some high bitrate content that I should buy a replacement device, but it still works well enough. I tried upgrading to a newer raspi and wasted an hour trying to get it to run, then gave up. So, I still use my old one. It still gets used daily and works well enough (only issue is the buffering on occasion).
2. RetroPie - I rarely game, but it's cool to be able to turn this on and have a library of all the games I played (and those I never had) from childhood.
3. I use the third one as a networked LED marquee controller (HUB75 panels) with this software: https://github.com/hzeller/rpi-rgb-led-matrix
The other 2 I just have sitting on my desk and occasionally use for small dev projects or to test out some new project I read about on here, hackaday, etc.
An ongoing project that I haven't made much progress with is an automated turret that squirts squirrels with water. I made something similar in college (a "paintball gun" turret with openCV blob detection/tracking) that had decent performance. Now that openCV on rpi can outperform my old college laptop, I want to setup the pi to detect squirrels, track them, and keep them away from a bird feeder/plants in my backyard.
One Pi3B+ connected to anemometer and single solar cell, uploads up to 60 secs of analog data reading every minute by CRON, then has other CROn stuff for emailing
One Pi Zero for home security camera attached to motion sensor/rapid shutter mode, uploads to S3 bucket
One Pi zero for reading HN news out loud in the morning by Amazon Polly, tracking solar cells on window, and then more scheduling stuff
I have another one powered by USB, I intend to use it as "swappable dev stacks by sd card" through USB SSH
Media player connected to tv. (Kodi or Elec, I can't recall which) What I found really neat about this is that if you use the HDMI connection, there is some automated setup/control that allows my tv remote to control the PI. (through the HDMI connection) But also, the smart phone app for Kodi remote control added a new layer of interaction with the media player that is just sort of unique and unexpected. (everything…
1) PiHole. I'm upgrading this to a RasPi4 and seeing if I can also merge 2) 5) and 6) into it.
2) NAS/VPN/Media Server/Hass.io
3) RTL-SDR for ADS-B Receiver feeding to numerous data warehouses (Flightaware, ADS-B Exchange, PlaneFinder, etc)
4) Connected to RTL-SDR and running rtltcp for generic HF/VHF/UHF radio receiving which was previously part of a SATNOGS automatic cubesat/Amsat/ISS receiver build I've not completed yet.
5) Debian desktop on my workbench
6) A Pi Zero W running a ZNC IRC bouncer
7) Experimenting with remote ham radio control but linux-based ham radio software is still a bit too frustrating, so this isn't an active project.
8) Two extra RasPis and three PiZeroW's just lying around because Microcenter always has them for ridiculously low prices.
