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.

Lemme think. A camera that observes the room from the portrait, anyone that walks in is a dot on a plane, and it points the eye at the point on the plane. Should be doable. Yes, the Pi should handle that fairly easily. The part that you'll have to figure out is making the eye ball rotate. There are GPIO pins on the Pi, so you can get the commands out, but you'll need to build the eyeball component yourself.

Probably not. Servocity has x-y gimbal controllers. If you can find one small enough, it could control the eye.

Using several Raspberry Pis to monitor CO2 levels in my house. Each Raspberry Pi has a CO2 sensor - wrote a little Python script to retrieve data from sensor and upload it to a server Which is also a Raspberry Pi.

I'm interested in this too. It would be even cooler to link these CO2 sensors into Apple's HomeKit somehow...

I have 4 raspberries running 24/7:

- 2x Raspberry PI 3B+ in my office running 2 custom dashboards with info related to my web projects. One also runs Homebridge.

- 1x Raspberry PI 3B+ running pivpn.io

- 1x Raspberry PI X running an energy monitor (bough it as a kit

I threw my first Raspberry Pi in the trash just last week.

I have one running pi-hole and Ubiqiti controller (powered by my router's usb port), one sitting under the TV running Kodi connected to a NAS, avoiding the need for discs (big plus when you have small children), one sat next to an old hi-fi which also links to the NAS and lets me stream music to the hi-fi, and a couple of older ones which aren't connected to anything having been replaced with newer models. Oh, and a…

I also do the PiHole + Ubiquiti controller w/ PoE, it’s a cheaper and more robust solution to the CloudKeys!

A security camera NVR. (Help wanted! I'm developing it here: https://github.com/scottlamb/moonfire-nvr I'm proud of the design but it's still far from a polished system that does everything a reasonable person would expect. Lots of opportunities to extend it if you're looking for a fun Rust + Javascript project.) A Raspberry Pi 2 will run a working setup; the new Raspberry Pi 4 should be a lot more pleasant in terms…

You got a '>' as part of the URL, which goes 404! Just removing it should do.

I have a pair of Pi Zero Ws set up as timelapse cameras that I keep in the garden - Cucumber vines and flowers opening is pretty interesting at 1 frame per minute I recently did a project with a pair of RPi 3b+ and cellular modems as construction cameras. I set up RetroPie on a 3b+, but it wasn't enough for the N64 games my wife and I wanted to play the 4 could change that Currently my security cameras are recorded u…

What is your take on the cloudshell? Genuinely curious.

I have 4 running at home as servers:

- an OctoPi server, which allows me to manage my 3d printer remotely.

- a VPN

- a Plex Server, serving media to my TVs and phone. I just ordered the new 4GB Pi4 to replace this one. I’l probably re-purpose it as an OctoPi-like box for managing a CNC.

- a seldom-used retro gaming box, that’s actually been mostly by a hacked Playstation Classic

I've got 5. I only actively use 3 of them. 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…

Would that turret will work for pigeons landing on my balcony? Or better yet, to protect my air space by squirting them on a fly by? That'd be some sweet fun. :-)
