How many Raspberry Pis do you have and what are they used for?

Just the one here a 3b+ running octoprint. I did fiddle around with it a little and did quite like it. Some of the projects in here are really cool. I keep meaning to get one to play with but have little real world use for them aside from tinkering.

I've put the shelly between the meter and consumer unit so it measures total usage (I think), been turning more lights off than usual ;)

Ah I didn't realise they made one with a CT clamp, although that's quite expensive considering you could make something up for quarter of the price. Which is unusual as shelly devices were pretty well priced.

Not sure about a quarter of the price given the effort needed to build in all the web functionality, I always was a lazy coder though. Happy with my used item :)

Has anyone done much with object detection and general machine learning? I'm thinking of doing a project for an autonomous vehicle with object tracking capabilities, but would likely need to have better ML processing through something like a Coral or NCS2 USB type interface.

Looks like there are a few good tutorials out there, but is anyone else working in this space?

I now have 4 Raspberry Pi's. The 4th arrived today unexpectedly, a free Zero 2 W from Magpi Magazine.

Pi Number 1: 8Gb PI 4 which is used as a desktop computer/talking to headless Zero machine.

Pi Number 2: 2Gb Pi 4 running Apache and I am using it as a server to test my web programming on.

Pi Number 3: Pi Zero W which is running headless and used to photograph Hedgehogs in the feeding station.

Pi Number 4: Pi Zero 2 W, which is sitting in an antistatic bag waiting to be found a use for.....

All these Pi's and I do not even have a wispy beard or strong spectacles.

Interested in the 3 one as we too have visiting hedgehogs. How do you power it and so forth? Wouldn't mind building something similar.

At the moment it is powered by outdoor extension lead as the feeding box is outside the dining room window. It has just been upgraded to the Pi Zero 2 W. I ought to try batteries and/or solar charging but never quite get round to it.
