I used my Raspberry Pi 3 B+ to control all Fish tank equipments remotely. We live in a city (Chennai, India) and my family usually goes to our native for 2 months every year during summer vacation. During these times, it find it very difficult to manage the equipments. The Raspberry Pi controls 2 Lights, 2 Filter pumps, Cooler, Fish feeder, and CO2 cylinder. Am planning to attach a camera and some sensors to the syst…

I always wanted an aquarium and this was the sole reason I never got one, thanks I'll look into it.

Can you tell what are your equipements and whats the setup like? (sorry, if already mentioned in github I can't open at work)

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…

If the buses have GPS then Montreal should launch an app. They did that here where I live and now everyone can see where each bus is, live, on a map of the city. Best thing ever for us control freaks.

I tried making a "travel access point" with mine, so I could have all my devices already setup to access a single access point and funnel all the traffic through that. I was previously using a $20 router, but curiously the Pi 3B just didn't want to play ball, dropping packets / connections and generally sucking. :(

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.

Don't be sad on my account. I actually like them very much. They are funny and persistent. I watched one yesterday try to outsmart a crow for a piece of cheese. That she even tried was pretty courageous. We have an obviously-paired couple living on the roof of the building next door. They are very sweet and would be welcome to visit if they would promise not to nest. But they won't.

And the first pair of baby pigeons we sheltered was the last pair of baby pigeons we will be sheltering. The mess was indescribable and everyone was so comfortable they all wanted to raise families here. Horrified, I chased pigeons from our balcony during mating season (circa any time it's warm outside) multiple times a day for three years before I regained control of my tiny kingdom.

Pigeons have the whole outdoors to nest in, the city even maintains a pigeon house on top of a building just across the way. I have my balcony...

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…

> I VPN in to my home network, ssh into the pi using Terminus on my iphone, and 'aplay' the wav file Once, when I was working away from home, someone unplugged the phone at home so I couldn't phone in. After becoming very frustrated, I SSH'd into my home server, and from there into the Mac Mini we used as a media station. Then: - checked they were watching something using `ps`. - killed that process so I had their at…

Haha this reminded me of the time I lost my phone. I suspected it was left at work so I ssh'd into my Mac at work, started recording audio, dialed up my phone and voilá. It was there and I had peace of mind until tomorrow.

At one point, I figured I wanted some lighting for my bar, which consists of about 70 bottles on shelves (about 1.2m wide and 2m height).

But a simple on/off is not good enough. Instead, I went with individually addressable LEDs (NeoPixels strips to be exact), and developped my own back-end to manage those LEDs, with a simple front-end.

So far, it supports lighting bottles individually, by category (rum, vodka etc...) and some simple animations across the whole bar.

It's a nice ambient lighting, and it serves as a show-off for guests.

Plus the whole thing runs on a second-hand computer power-supply. The Pi runs on the power-supply power-on line so that when no LED is on, the main power-supply is shutdown to reduce electricity consumption.

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?

He told it: random ones.

Things I use Raspberry Pis for:

* Pi-hole

* Home Assistant

* Processing assistance and PPP/Serial and tcpser connection for an Amiga 4000

* MyCroft personal assistant

* Octoprint for 3D Printing

* MotionEye camera management (Moving across to a NUC)

* A 4 node pi-zero cluster using a ClusterHat for distributed Pi approximation optimization I normally run once a year on Pi day.

Much of this is due to the segregated way my network is set up, and the Pis have largely replaced previous OpenWRT devices, although some of these Pis have now or are in the process of moving to other more reliable systems.

Have you experienced any issues using PiHole? I would imagine some apps etc would go to lengths to prevent their use. But if it works I'll set one up for my partner who plays way too many spammy games.

Two areas where I've seen problems. One, sometimes I want to browse/buy things via Google Shopping (or some other shopping interface) but the Pi-Hole blocks it. Two, sometimes for work I will run a docker-compose script that say, downloads a copy of Puppeteer. For whatever reason the domain seems to be on Pi-Hole's blacklist. Granted I could probably whitelist the domains but that seems like a hassle. It has the abil…

Maybe you could create multiple wifi networks, one that uses pi-hole and one that doesn't.
