Ask HN: What did you build with your RaspberryPI?

9 pointsmaxwellito14 comments

Out of set up a classic distro (media player, retro gaming..), what did you do with it?

I'm just curious about interesting hacks and concepts :)

I wrote a few bash scripts with my pi and a remote NodeJS server to capture timelapse photos of my jalapeno plant growing and compiled them with ffmpeg.

Here's my writeup if anyone's interested, and a few gifs of the results.

I use Pi's to teach introductory networking concepts to undergraduates, configuring various network functions and building out a mini-Internet.

Hoping to get the projects polished up a bit more this quarter and to publish a repo with guides and configurations. I've also convinced a handful of students to tackle some more interesting applications and modern networking concepts in lieu of the standard course project.

Used it (along with an arduino) to control RGB LED strips for my Deck Lights project. It was great fun, then I sold the house and moved!

Used Remi for a web control gui and platform.io on the rpi to be able to program the arduino headless.

I built a kodi media player but it won't do Netflix so i bought a smart TV. I have many plans for my two pis but I'll probably never get around to doing anything with them. I wonder how many rpis are sitting idle on desks around the world

I've probably abused it too much but its shocking how much it load it can bare.

* Ebook Server

* Ad Block via DNS

* Router (needed me to get an expensive wifi receiver) over VPN

* Mini build system to publish my blog

* Auto-backs up my NAS box to S3 / Glacier (and then test-restore the latest backup) every month

* Auto-emails me based on a wide variety cron-jobs that check the weather, stock market, rss feeds, etc

* Grabs by RSS feeds and bookmarks

* Offline cache for some stuff

* Downloads videos for later reference

* Automatically texts me when I've not written anything worthwhile (in code or blog) for a while

[edit]

* Using it to teach python / basic programming

I built a smart home system with FHEM and HomeMatic for my second flat. I was able to turn on the heating, set and monitor the temperature. This saved my lots of energy costs compared to a timer-based system, as well as many cold nights because the heating didn't turn on at the right time. Neither the flat, nor the smart home system still exist. Once I move into a new flat, I'll build another one.

A heating system, thermostat, for my shed.

I hooked up a temperature sensor and relay to control a 500w heater in my shed office. A Python script checks the temperature every five minutes using cron and turns the heater off/on.

I also keep graphs. I only work in the shed on Thursdays/Fridays which are reflected in my graphs.

I built a solar panel monitoring solution:

Code is on Github: https://github.com/Tafkas/solarpi

Do you have details on the solar panel and the rest of the infrastructure? (or a blog post?)

This is actually a neat idea, though the design of the form page could've been better.

Built a Media Player using Kodi. Then Netflix happened.
