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…

In term of electricity consumption and maintenance is worth to run so many PIs?

The lowest power "x86" server I have found runs at about 30W, that is equivalent to about 8 RasPis (typically about 4W each, the PiDP-11 is an outlier at 8W) in the current configuration, and the RasPis are fairly distributed around my lab which would have to be done with wiring otherwise.

I'm Dr. Torq and have a Raspberry Pi in my Steampunk conference badge. Use it during my tech talks. I walk into the room, power down the badge, plug in the HDMI, power up the badge and run my slides with a nano-keyboard/mousepad and LibreOffice. Works great. When I'm walking around a show, the badge displays a little promotional video on it's 3.5" touch-screen. Runs on a big cell phone power pack, in my pocket.

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 like Pigeons and don't mind them except when they visit my balcony at 7am in the morning and wake me up (we only have single pane windows and no way to change it since we're renting).

Nothing yet, though I'm looking at possible projects.

The router and modem both run OpenWRT, which addresses any number of basic sins one might hope for, including adblocking, firewalling, and media server.

I am looking for options to provide streamed media over existing audio equipment in the flat. This might be applied to a media library (DLNA audio and video), podcasts, Internet radio, and borrowed items from libraries (local, online).

There's a set of devices which offer to talk to local audio equipment, much of which costs as much, and often several times more than, a RaPi. Seems that a full SoC system might be the better option, particularly if WiFi and Bluetooth are built in.

The coffee machine in our office is controlled by blockchain NFTs and a Raspberry Pi: Once authenticated, an owner of the NFT can select their coffee type on their phone which then signals the Raspberry Pi to make whatever coffee type was selected by jumping the contacts that used to be pressed by the machine's buttons (which have been removed). It's a cool gimmick, fun to show off to visitors, gives us a nice record…

> gives us a nice record of who is making coffee Is that allowed by GDPR?

If you don't serve cookies it is okay.

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…

I always think how i would feel about a known fire in my house. Would i leave my fireplace unsupervised for a longer period? Definitely not, and that is the one place that should be fireproof.

I use my Octoprint mainly for three things:

1: Controlling the axis for manual bed leveling (yes i level manually)

2: Upload the gcode files to octoprint (no fiddling with micro sd cards)

3: Watching the picam. So i can sit in another room, but so close to hear if a motor jammed or something else.

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

Would you mind going into your Plex server setup a bit? I tried using a Pi before but could barely get it to trasncode anything, and playback was miserable. Now I'm using a Kimsufi server, but I'd prefer to have a locally running server (that isn't my main PC) as my Plex media server

I'm using a NUC rather than a Pi for Plex, but I avoid transcoding on the server by just transcoding everything up front. Nearly every client these days can play H.264 natively.

This is one of the coolest uses of reddit/community sites that I have ever seen. Out of curiosity, how did you come up with this idea?

Trying to impress a girl with my plant-keeping abilities ;) --We had a collaborative message thread reminding everyone to water our plants based upon a set schedule which I was going hook up to a pump to automate, and at the time Twitch Plays Pokemon was a big thing, so I just kind of combined the two ideas. If you have interest in doing something similar, come check out the subreddit and feel free to DM me on reddit…

So finally did you impress that girl or not? :D
