With my 16 year old son, I built a weather balloon with one, including an Arduino, a few temperature sensors, a GPS, LoRA radio, and we're going to launch it next month. Having a hard time finding Helium.

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.
Is ngrok the new dnat?

#684There'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…
Big ups! I use this all the time in winter while waiting for the 55. I definitely assumed you worked at Ubisoft across the street! Btw, from some experience spending cold winters looking at it, it flickers a lot by having so many screen changes, making it tiring to see the screen change so much. L'AUTOBUS - SERA - LA - DANS - 5... - MINUTES - GREG . - TECHNOLOGY. It would be easier on the eyes if it changed less ofte…
Agreed on timing, it could be better. I'll consider skipping some of the words + make them appear slower. Thanks for the suggestion!

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'm thinking of doing the same for my kid. Any photos/description?
It's actually quite a bit louder than this now. Also, the lights aren't quite as infant-retina-searingly-bright as the camera would have you believe. https://www.youtube.com/watch?v=xtE8oE9GOsM Currently it's still running my test code, which just lets him mess with volume/pan/pitch. I need to get around to writing something a bit fancier. Tech deets: It's just a RPi3 with most of the stuff written in Python. I tried…

#690I'm very interested to see how OpenCV 4 and YOLOv3 object detection will run on the new RPi. At the current trajectory I will have to upgrade to a Jetson Nano to get hardware acceleration (CUDA), but resorting to specialty hardware seems like cheating.
They also make a great prototyping platform for IoT projects. I've built 802.11.4 (Zigbee) mesh radio networks for passing small messages across neighborhood distances.
Previously I used an RPi to run an Airplay Bridge to my Sonos speakers. This has since been supplanted by AirPlay 2, which Sonos supports.
