Default No black LEDs?

The TfL API is public, and other apps use it. But I get the impression here
that the API is accessed from a program running on the company's server,
with the boards communicating with that. This has the advantage of being
able to handle changes to the API, but obviously depends on the company
continuing to run its server, and updating its software as required.


They are using an ESP8266, which is a small, relatively
underpowered WiFi microcontroller. They say it's talking to the company
server rather than handling the full API.

There are open about that, and describe how to reflash the microcontroller
with alternative firmware if you so desire. There are other popular ESP8266
firmwares out there and it probably wouldn't take a lot to adapt to
refashion to an alternative server if the first one became unavailable.

you represent Northern Line trains? Yup, in white.

Just the thing for a Tube nerd with £249 to spare! An ideal present for


someone who grew up in London but now lives in exile.

Looks to me like it only shows trains in stations, not all trains on the

line.

I'd be interested in knowing where it gets its info from. Is it a public
API anyone can connect to or is it paid subscription included in the price
of the board that will eventually run out.

Is that for real? Many trains seem to be running cross country, running in
close formation, suddenly reversing half-way along a route, and generally
running too fast.


I doubt the API updates nearly that quickly so I suspect there's a lot of
extrapolation going on.



I've just looked at it now, and it seems to be behaving more sensibly. I
don't know if they're correct and up-to-date, but the train movements are
plausible. There must have been a glitch yesterday, when they looked more
like a swarm of bees.

It sometimes has glitches where it tries to catch up with that sort of
effect. Looking at it at the moment I can't see anything obviously untoward.


Yes, it looks plausible this morning, quite different to yesterday.
