Sounds like there is a market for fire standard approved cat doors! ;) I loved reading what you are doing with the Pi though.

As you might have guessed, that came to my mind too. Due to the fact that I have worked with a company in the fire damper business, I was contacting them and we were brainstorming about it. The thing is: The market is just non existent. Also fire-protection regulations can be very specific depending on the country you are in. For example, EU ratings are not always recognized here in Switzerland. Since last week I'm i…

A fun dream I've had (context: I've always been confined to apartments) is some sort of cat/pet utopia in a block, so they wouldn't be stuck inside alone. But that wouldn't be feasible since they have to navigate the fire-proof doors between floors...

Unless your cat door goes to market. May luck be on your side :)

(really, don't underestimate niches, you can probably find plenty of places to sell this sort of product...)

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…

You could automate this even more with a Twilio number, ngrok running on the Pi and a small webserver to trigger the audio playback. Then instead of having to ssh in you can just send a text.

If you're running a web server, why not just put up a page with a "ring" button and bookmark that on your phone?

Nothing too exciting. I've got an air purifier set up with homebridge and run a PiHole from it. I've also used it to practice setting up websites from scratch.

I'm using mine as a kitchen computer to lookup stuff online. Not exactly a Pi, but I used a adafruit feather to detect vibrations. I used it for landscape photography with a super telephoto lens where I wanted to be able to detect vibrations before firing off a bracketed shot.

Squeakernet FLP is not a cat feeder, it's a feline lifestyle platform. Current features are largely focused on kibble deployment though. https://github.com/buzzcola/squeakernet/

You look like the author of this? Could we get some more info on the scale and dispenser please?

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…

This is awesome work and thank you for doing this for public without asking. P.S. does the transit authority offer an API or is this prone to breaking when they change their page layout? [edit: I just read about the rumor on your webpage. Clarifies.]

If you use MITMProxy or Charles you can easily intercept the traffic on 99% of all iPhone/Android apps (bit harder if pinned-sertificate). These API’s are often stable because a lot of users don’t update their apps that often.

A Pi 2 at work runs a Grafana playlist on a spare display.

A Pi 3 at home runs a Flask server that collects data from sensors around the house (ESP8266 + SHT20 for temp/humidity), and provides a web page that overlays sensor data on a diagram of the house. I've been curious about CO2 levels in the bedroom overnight, and have parts for that experiment on order.

College student here with a part-time data entry job. I have automated nearly all of it using Python, Selenium, and a few nasty bash scripts called by periodic cronjobs. Recently purchased a 3b+ for the task so that I can travel without worrying about AirBnB wifi speeds. If I need anything I can just SSH or VNC into it from a coffee shop. It just sits next to my router and blinks all day doing my job for me! Best $35…

Can you explain more about what kind of data entry is that exactly? Also how exactly did you automate it? Have you written about it anywhere?
