What I would pay for is:

A preconfigured raspberry pi, maybe with case, that automatically saves multitrack audio from a USB card. When you plug it into a Soundcraft Signature MTK audio interface (USB soundcard), at boot it waits for sound and reads all the live input channels and saves them to disk.

That way, we could record the full multitrack of our sessions very easily, and not necessarily need to have a laptop computer involved.

Edit: I would also pay for this if it shipped: http://www.samplerbox.org/ which is a sample-box for a MIDI keyboard. So also taking instruments off a laptop and into a smaller device.

I don't know why people don't sell prepackaged RPis for a mark-up for installing software that just boots and has sensible defaults.

I'm kinda concerned by the number of mentions here of using the Pi to run OctoPrint (I think that's right?) to remotely admin and monitor a 3D printer... I've always been of the mind that a 3D printer should never be left physically unattended - even with monitoring (via camera and such), as they can potentially start a fire if something goes wrong (failed print spewing random filament?). Is this a wrong viewpoint? A…

You can also get a small automatic fire extinguisher like they have for grow rooms and over stoves to help mitigate. Having that in an enclosure with some leds and a webcam would be a decent mitigation. Checking in on the print every now and again is a good call too.

A security camera outdoors (connected to another webcam outdoor), when there is motion it will send a request to another indoor raspberry (node server) connected to a speaker and will play the sound of an angry dog. The system is working fine for more than a year without breaks. Raspberry is robust.

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.

Its a great little box. I have 2 or three cameras recording 24x7, a large chuck of the spinners is a Samba share, and Webmin tells me that I'm usually at 10-20% cpu and 25% memory. I've got an SSD connected to USB also, and it really makes the spinners feel slow ( WD Red Pros ) but that's mostly because they spend a lot of time idle and the first access is delayed. Of course it isn't perfect. It holds on to dust a bit too well, and it isn't super easy to connect another USB device once you get it all dressed in place. I don't use the screen. I did at first, but I'm not black-belt level at managing HDMI devices and it doesn't present as much value as the light pollution it causes. The RockPro64 would probably best it in most tests, but I already had the Cloudshell. I have dreams of incorporating it into an all-ARM Linux domain classroom.

I got an AdaFruit servo hat and I use it to drive my hexapod. I used to use a Propeller and then an Arduino. My next project is to integration some vision recognition into my robot. I am planning on using a Jetson Nano for the vision part, but I believe switching to a Pi for the robot was a helpful precondition. I haven't decided if I will just use the Nano to control the robot or use it as a visual co-processor with the Pi.

Old video of my hexapod below. Still works great though, because it is really sturdy.

https://pi-hole.net . Just installed, very happy so far.

How do you deal with it breaking things like Amazon-based UI(Fire, Mobile shopping etc...)?

I'm not OC, but my solution there would be to seek non-Amazon based UI :)

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 like this! I'm already using Pi Zero's like this for temperature sensing; adding a CO2 sensor sounds like a good enhancement!

This would be a good application for a Pi Zero W (with WiFi) - if you want to collect the data in a central location. I've linked the CO2 sensor I used in another comment.

I will use my first one to power a hard drive that I leave with family or friends. They'll have a small box (mind the inclusion of an external hard drive, still a relatively small box) with my off site back up, and I could host the same for them. This is after a failed plan to use it for Android TV (my girlfriend made the mistake of picking a WebOS TV and I made the mistake of thinking it wouldn't be so bad). The old…

Regarding your mutual backup idea, I love this and I've wondered why this hasn't taken off as a Thing in response to how many of us are untrusting and DIYers in this era of cheap storage and bandwidth.
