Re: Ask HN: What do you do with your Raspberry Pi?
#812I have a few Raspberry Pi boards and since I've seen folks doing stuff similar to what mostly do I thought I comment on something I hadn't seen yet. I struggle with tinnitus distress and Ménière's. One of my coping strategies is to continuously play some sort of background sound in the areas I occupy. I have a first gen RPi with a set of USB powered speakers in my bedroom that plays long form background soundscapes I…
As someone newly with tinnitus, and with fading hope that it will go away at some point, I've been playing around with ideas of doing something like this. I was thinking of using frequencies to cancel each other out, but I think this might work much better.

#813I have 13 in service right now: - Outdoor irrigation control via OpenSprinkler Pi: https://opensprinkler.com/product/opensprinkler-pi/ - Z-Wave home automation via ZWay: https://z-wave.me/products/razberry/ - 2 Custom HAVC thermostats using: https://github.com/jeffmcfadden/PiThermostat - An NTP server with GPS attached for a time source. - 2 for weather monitoring (one directly attached to sensors, one that aggregate…
Seems like a Pi is overkill for a few of these, why not a micro?

Wow. I literally just sat down to relax after building a cardboard prototype cat door fitting in my open window in winter. You just made me feel partly inferior, and partly like I'm in good company
Now check out this project: https://www.youtube.com/watch?v=1A-Nf3QIJjM A cat door that can tell if the cat has a mouse it's going to "gift" to you, and locks to keep the cat out.
I may now get a cat just to set this up.

#815I hooked up the raspberry pi to an old monitor I hung over the kitchen table. It boots up shortly before dinner time for an hour and then displays "Find my Friends" on Chromium in kiosk mode. (Inspired bij the Weasly family clock from Harry Potter).
It's a fixture I couldn't live without anymore. When family members travel you still feel connected. It has a tiny ruby script to rotate through pages, during breakfast it displays the kids' upcoming class schedule.

#816A security camera outdoors (connected to another webcam outdoor), when there is motion it will send a request to another indoor raspberry (node server) connected to a speaker and will play the sound of an angry dog. The system is working fine for more than a year without breaks. Raspberry is robust.
Interesting. Would you recommend some brand of security cameras that work well for this kind of projects. Where I live the more popular brands are Dahua and Hikvision. Maybe I have to look for a certain communication protocol, rather than for a special brand.
In my case the security camera is also a raspberry pi with the camera module (it could have night vision), connected with a webcam logitech c170 (really cheap) and the motion software to detect movement (https://github.com/Motion-Project).

#817I use them to convert old industrial equipment into oddball control surfaces. For example http://www.digitalesoterica.net/projects/honeywell.html

#818Currently:
* I use a Raspberry Pi Zero-W and a neopixel strip to tell me the time at night. This post describes part of it: http://www.thebacklog.net/projects/smart-light/
* Run a piHole at home.
Things I've done in the past:
* Use a Raspberry Pi as an intervalometer to do time lapses with a DSLR camera
* Make a photo booth for a 2 day workshop.
* As a cheap computer to run coding tutorials
* Monitor water levels in a hydroponics system using a ultrasonic sensor
* As a WiFi access point to access a wired network from my phone

#820For those of you commenting about the mechanics and pitfalls, I've found that a Pi3B+ with the 7" screen and a keyboard/trackpad is a wonderful tool for provisioning new cards. I do headless system configuration on that, then swap to the Zero or whatever it'll actually use. Since the BSPs for every board are tiny, there's no reason to limit yourself to something that can't work on all of the boards out there. It makes troubleshooting a lot easier. Also, don't buy crap SD cards, and probably have 2x the number you'd like to have running. This stuff is cheap so that you can have multiples for testing.
