You are a kindred spirit. I have: 2 pi NTP servers - one running a GPS hat + PPS wired up, one using a USB gps receiver. a "workhorse" pi - 2 wired ds18b20 temperature sensors, cron jobs, email generators, weather page generator, connectivity monitor. One pi running piubos + nextcloud. One pi running as a clock. One pi running as a wireless temperature receiver. a few floating pis running media center or retropie or…

Just curious, what kind of cron jobs are you running?

At the moment I am using a few pi to control my garden systems. I just built an open source system (https://mudpi.app) to help manage the sensors and relays. Actually gearing up for a launch soon.

Being able to regulate my watering and control it from my phone as been awesome. The whole thing emits events with sensors on redis so its open for systems to hook on top of it. Pi was the ideal choice to keep inital costs low. The amount of power you get for the price is pretty sweet.

The other pi is running the same code moderating lights on a basement shelf of plants too.

The last pi I am using retro pi to play some old school roms.

There's a bus station across from my studio / coworking space. I can see people waiting for the bus and doing either: 1) staring into the void 2) looking at their watches 3) desperately glancing in the direction where the bus is coming from. I figured that it'd be nice to let people know when the bus is supposed to be there. So, I installed a 28" display on a monitor stand, installed the stand on my window frame, tur…

Ah, so that is your work! I always found it amusing.

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.

As a one-eyed individual, I love this idea. I have my old one sitting in a drawer doing nothing and I will be replacing my current this year. Two glass eyes.

I've got a 3b+ and a 1b, and whilst only the 3b is in use currently, I have plans for the other.

The 3b runs libreelec for a tv in my bedroom. I found my 1b to be too slow for this, but the 3b+ does admirably.

The 1b, I hope to repurpose into a couple of services:

1) a pihole for my home network

2) a Wireguard VPN for connecting my phone back to my home network.

This is all sort of waiting on me getting usable internet, because my 700kbps upload currently sort of makes it pointless. However, I'd like to do this once I have better internet so I can use my phone as if I'm on my home network. This will provide me with several benefits:

1) I will be able to stream media when travelling for work

2) My phone will benefit from the pihole even when out and about

3) I will be able to control my home network as if at home

4) It will provide another endpoint for hurdling the GFW when I work in China

I hope to start all of this next year, once I move house or when I finally receive a proper internet connection rolled out to my place. If the 1b is too weak for those services, then I will probably repurpose it into some sort of automation system for watering plants, since once again due to work travel I routinely have to lug them over to relatives' houses whenever I'm away for a week or more.

Big ups! I use this all the time in winter while waiting for the 55. I definitely assumed you worked at Ubisoft across the street!

Btw, from some experience spending cold winters looking at it, it flickers a lot by having so many screen changes, making it tiring to see the screen change so much. L'AUTOBUS - SERA - LA - DANS - 5... - MINUTES - GREG . - TECHNOLOGY. It would be easier on the eyes if it changed less often.

Thanks so much anyways!

1. Rpi 3 keeping my IRC session up and working as small server for small tasks. 2. Rpi 2 has zigbee-module (raspbee) which controls lights. 3. Zero W with camera is currently doing nothing.

I have an old Raspberry Pi 1 that runs headless raspbian with a set of cheap speakers plugged into it and an old usb wifi adaptor. It has only one purpose: to play a wav file of a telephone ringing for one minute. My spouse does not ever have the ringer on her cell phone. So when I am out and I need her to look at her phone, I VPN in to my home network, ssh into the pi using Terminus on my iphone, and 'aplay' the wav…

Similar issue, but I worked around it by setting up one of those find-your-phone apps and whitelisted my number. Now I can just text her the secret code and it makes her phone ring loudly even when it's on silent.

This would be really bad if she happened to be at a performance, restaurant, active shooter situation, etc.

Better off forcing a ring in the home than where you can't foresee the consequences.
