I'm totally naive with Raspberry Pi..can someone comment on the following project: Is it possible to put a glass eye behind a portrait of a one-eyed pirate and make its eye move around/follow whoever enters the room? A friend has a glass eye but nothing to do with it.

If I hadn’t started this startup and had time, I would want to start making this right now

Low-cost Aarch64 development machine! I run Aarch64 Fedora on a Pi 3B+ for porting personal projects to Aarch64 and for testing. When mainstream desktop ARM arrives (ARM Macs perhaps?), I’d like to be ready in case I have to make a switch from x86-64.

I'm building a CarPi. I'm using a bluetooth OBD-II adapter and Python-OBD to monitor my car's diagnostics and record them. I'm planning on adding a GPS adapter and probably a gyroscope/accelerometer so I can track location and motion at the same time.

It's mostly just for fun.

Maybe one day I'll add some kind of analysis to it. It might be interesting to track location, motion, and car status in order to predict mileage or if the engine light will turn on.

Doorlocks of our hackerspace has been RPi controlled almost since the original RPi came out, maybe 2013. Nowadays we got 4 doors on 3 RPIs (internal and external), with over 200 members that has access. Using MQTT to communicate with our membersystem since 2016 or so.

I used mine as a NAS for a while with an external USB HDD and a samba share. It was also set up to be a VPN and pi-hole. I have a pi zero that I use to flash coreboot on laptops.

My PS3 isn't doing so hot as a media server client for my NAS's movie library - the network connection is poor, the interface is fiddly, and it can't load subtitles embedded in files. I was going to buy a pi3 to replace it as a media server client and hook up an external DVD player, but now I'll be getting a pi 4!

I used it to monitor ADSL device status[0], also created a DIY timecapsule for MacOS[1] — these were all in the past, though. Currently the Pi is on my roof, connected to an SDR. I sometimes run rtl_server on it, and listen around. Although it's been a hassle, since I have to run upstairs and disconnect it everytime there's a storm. Also, listening to the device over WiFi means I get really laggy control over my SDR.…

You could probably automate cutting the power with a relay switch also connected to the pi. Just scrape weather data, and if you expect the storm, trigger the switch.

1. simple server for backup and git repos

2. xbmc for videos on main tv

3. retropie (I had fun with this for about a week but haven't used it lately)

4. pihole for blocking ads and time-wasting sites

5. various small projects: security camera, motorized window shade, etc.

I run Home Assistant on my desktop to communicate with a few of the other devices in the house but I might move that over to a Pi so I don't have to worry about restarts and performance. I'm thinking about consolidating this setup somewhat but I'm waiting for my next move.
