I built a small hardware device to show the departure time of the tram next to my house, because here in Finland it gets cold in winter. Mostly the winter isn't super-cold, something like -10°C/14°F, but there are weeks where it will be -20°C/-4°F and then there's a big difference between waiting at the tram stop for 1 minute or 7 minutes.

As someone who lives in England seeing -10C described as “not super cold” is interesting, I guess perception of these things varies a lot depending on where you live and how prepared you are

I moved from Scotland to Finland, so I guess I'm familiar with the UK temperatures ranges!

I'm generally one of those people who is always warm, so with that caveat inmind I don't find -10 to be too difficult. I can travel to the office, or shops and back with jeans, t-shirt a hat and a decent jacket.

It's only when things get colder than -15 or so that I need gloves, a scarf, and more layers. That's the kinda temperature where your face starts to hurt when you're outdoors, and daily life gets unpleasant. You start to think "Maybe I'll go to the shop tomorrow", and plan things so that you don't have to go outdoors like that.

You and me both! Here in Canada it can easily reach -30 and I go out with tank tops. I have a theory that if you can control your inner temperature, you won't feel cold, so it's an intrinsic thing. Although some of my colleagues exploited this when we used to go to the field to fly and test drones during harsh winter, they would bring up that theory to me to be outside while they were cozying up in the car!

I look when getting a bus/train if the frequency is less than ~one every ten minutes. I never look for trams (those are ~always headway <10 mins for the routes I use).

Different people have different thresholds. some go as high as 12. it is generally excepted that until you get to 7 most people are checking the schedule before leaving the door. there is noticable bumbs in ridership down to 5 minutes (not always enough to pay for the costs of that much service) so that should be the goal if a system can do it.

Ah, didn't realise there was actual data on this, though I suppose it makes sense that there would be.

Cool! Hey I have a feature request: Could you add the robotic voices? https://www.bart.gov/news/articles/2009/news20090309

When Noisebridge was new, I wrote a program to get the BART arrival times and play them (in a synthesized voice as close as I could find to the BART one, though clearly not the same one) through the loudspeakers at the space during the last half hour or so of BART service every night. Unfortunately, other people found this annoying, so it was disabled very quickly.

When was Noisebridge new? I started going around 2010/11

Very cool, I built a colored one for Swiss transit ( https://sschueller.github.io/posts/turning-a-project-into-a-... ) and turned it into a product: https://www.stationdisplay.com It runs on an ESP32-S3 using the government provided open data. https://opentransportdata.swiss

Is my conversion ratio incorrect: ~1449CHF == $1800USD?

Cool project. Everyone else has made good comments. If I could add a little criticism I felt your "and then I added a computer because I didn't want to write the ESP32 code for interacting with the API" did substantially change the character of the project and felt a bit like a rug-pull vs the promise of the first sections of the post.
