#672A Pi Zero W at work, controlling an LED from BlinkStick which change color depending on my presence and status, monitoring my position and calendar through IFTTT.
I I can also change it manually through HTTP GET commands on the BlinkStick server with my API key.

#673Earlier quoted context omitted.
Similar issue, but I worked around it by setting up one of those find-your-phone apps and whitelisted my number. Now I can just text her the secret code and it makes her phone ring loudly even when it's on silent.
This would be really bad if she happened to be at a performance, restaurant, active shooter situation, etc. Better off forcing a ring in the home than where you can't foresee the consequences.
Ah yes, daily active shooter situation...
In the same sentence as performance and a restaurant, not less.

#674I use it to remotely start my computer. My raspberry pi is always on and i use "wake on lan"[1] to start my desktop whenever needed. My desktop is powerful and consumes decent amount of power. Using Rpi to start is lot more power efficient.

#675A project I want to do: use an rtl-sdr to catch temperature readings from a BBQ thermometer off the air. Then push that data to prometheus/grafana and get alerting when the brisket is done.

#676I use a RPi Zero W to run DakBoard: https://dakboard.com/site which my family uses to organize our life. I'm planning on adding another Pi as a Pi Hole device as an experiment in parental controls via low TTL values to provide scheduled access to specific DNS names. For example, my kid gets distracted beyond all that is reasonable by Discord and I'd like to let him use Discord, but only at specific times. Anyone with…
You can probably run it on the same Pi Zero using screen? Am not sure if it will have enough juice to run both though.

#677Hack NASA. It's great.

#678There'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…
Awesome! This has reminded me of an old Heroku app that has been sitting idle for years: https://wmata-status.herokuapp.com (before the Silver line, which is why the UI is all wonked now) I wanted to do something similar to try and reinvent the old/ugly/hard-to-parse televisions scattered around the DC metro.
I believe the UI is great and will work perfectly on big-screens installed at stations. Kudos for making the app and such a nice UI.

#679I use a Raspberry PI Zero / 3 together with a phat dac for a bluetooth audio receiver / Airplay in my car:
Auto-Installer: https://github.com/BaReinhard/Super-Simple-Raspberry-Pi-Audi...
PhatDac (hardware): https://www.amazon.com/Pimoroni-24-bit-192KHz-Sound-Raspberr...
Alternative (hardware): https://www.amazon.com/Audio-AUDIO-Raspberry-Better-quality/...
It can be controlled via buttons over bluez / dbus via infrared remote and buttons:
Button Shim (hardware): https://www.amazon.com/Pimoroni-PIM301-Button-Shim/dp/B07HCP...
Bluez API: https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/...
DBUS control script: https://github.com/sandreas/raspberry-bluetooth-receiver/blo...
Unfortunately it is not possible to set playback position via dbus (see https://stackoverflow.com/questions/50190477/bluez-and-dbus-...), so rewind 30 seconds is not possible atm.
