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 Media player connected to projector running RasPlex - this software is outdated enough and buffers on some high bitrate content that I should buy a replacement device, but it still works well enough.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. :-)

This makes me sad.

Pigeons get a bad time, but they're lovely birds of you spend some time observing and maybe even interacting with them. We had an obviously-paired couple visit our balcony most days for a couple of years.

Please don't be (thoughtlessly?) mean to them.

I have several

* Pie-hole and runs Nagios to collect information about things going on inside the network.

* One running a PiDP-11 (pdp 11/70 emulator) as well as providing MOP service to boot my DEC terminal multiplexor (it provides the boot image when the mux comes up)

* One is a stratum-1 time server using an Adafruit GPS module with PPS output. This because I got tired of both the reflection attacks and trying to manage ntp access from inside the house to outside.

* One runs RasPBX and talks to the VOIP phone that is my home "business" line.

* One sits on my electronics workbench and runs OpenOCD and allows BlackMagic Probes to export GDB as a service over the network. That lets me debug from anywhere without burning a USB port or adding additional software.

* One runs a very simple time series database and is the collector for IOT type devices that are sending various bits of information (energy use, temp, humidity, particulate levels, etc)

* One drives a display which has a dashboard of various things that the others are doing (like Nagios alerts, data trends etc) This one is a candidate for replacement as the 4K monitor would be nice here.

* One runs the waveforms live software from Digilent and hooks to an Analog Discovery 2 on my workbench. (scope, logic analyzer, etc)

EDIT: And its important to know that I boot them using the network and run them off NFS from a NAS box, the idea being that when they break I can easily swap the CPU part with a new one.

Pi-Hole, RetroPie, and for my 1st-grade son I installed Kano OS for his first computer. I see a couple of Pi 4s as upgrades in my future. Also looking to get my SDR rig up and running on one of the other Pis i have waiting to be used.

Anything you've learned to share about having it as a computer for your first grader? I recently set one up for my daughter, same age, but haven't put much thought into the software side yet. She's played Minecraft-pi a couple of times, we made the cat meow in Scratch, and we used it to watch a movie the other day, but that's it so far.

I've got a RPi 2 running PiHole and a SAMBA server for a bit of in-home file-swapping convenience. ("Just throw it on the server and I'll pull it from there!") Currently my problem is that samba will fail to write files greater than around 100+ MB uploaded to the server. (Writing to a USB drive). It still handles multi-gigabyte downloads ok. I've been able to work around it with SFTP uploading, so it's just a minor a…

I have mentioned this is a few comments, check out the RockPro64, its got 6 core processor 4gb ram, and runs Dietpi. It has a PCIe port, you can install 2 sata drives. I just installed an SSD and it's awesome so far.

80 bucks for the 4GB, includes all the stuff on the new pi though. Interested to see how the pi4 stacks up

I run a grid of about 250 Pi 2 and 3s across several offices and datacenters. They are the backbone of our graphics playback system (i.e. slates) and low latent IPTV system. Users can subscribe to any channel necessary without expensive re-encoding or RF antenna systems. I absolutely love them and 4k60 HEVC is a huge upgrade for the 4!

Wouldn't it be less expensive and simpler to buy a few real servers ?

Not at all. $35 for a pi and $200 for HDMI>SDI converter is significantly cheaper than any media server with that many broadcast outputs.

For IPTV - each TV needs a decoder. Hard to beat $35 per set. Plus running our own stack means we can tune for latency unlike an app on Roku/ATV

We're actually running multiple of them (different generations bought at different times, one is even some similar product)

* company ownCloud server

* company wiki, company IRC server

* private RaspberryMatic instance for doing smart home (HomematicIP) without cloud
