Ask HN: What do you do with your Raspberry Pi?

Re:Ask HN: What do you do with your Raspberry Pi? by codetiger on Tuesday June 25, 2019 @04:27AM (#20272146)

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 system as well.

Right now, all these components are controlled by simple scheduling, but am planning to extend the control through a server in future.

The Pi is connected to a 8-Relay board and is attached to a extension power board. So this setup can control just any equipment.

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)

The config file in GitHub already has the schedule for each component.

Equipements: 1. Lights 2 (One for plants and another colour LED light that came by default with the tank) 2. Filters 2 (One Canister filter and another top filter) 3. Cooler 4. CO2 cylinder 5. Fish feeder (Built myself)

Currently, some equipment are always ON but planning to allowing to control remotely in future for triggering automated maintenance routine.

The Pi is controlling an power extension box using a 8 relay module.
