The DARC side of Munich

[New DFI Displays in Munich for Bus & Tram] When you live in Munich and use public transportation, especially Buses and Trams, you will have noticed that during the last couple of month a lot of new displays appeared at almost any station which had no real-time info display before. They obviously have no cables/connections and no visible antennas, so I kept wondering:

  1. How do they get powered?
  2. How do they get updated?
  3. Can we access the data as well?
  4. Is it possible to display other data?

What follows is a journey describing how it's possible to answer these questions and learn something completely new in just a couple of days with the help of the Internet and other kindred spirits who shared and published their research and results. Read on and you will learn how the system works and get detailed answers to those questions.

Call for Help:
If you see one of these Displays, please have a look at the top of the left side of the blue case, there should be a 4-digit numerical ID. Please drop

  • the ID
  • the name of the stop and the direction

in the PAD, a comment or on IRC.

Patreon killed itself (behind the scenes)

TRANSCRIPT OF CALL BETWEEN MATT CHRISTIANSEN AND JACQUELINE HART OF PATREON, 12.20.2018

JACQUELINE: So I wanted to reach out to you - we’ve had a lot of creators on Patreon with concerns. And there was obviously a lot of concern last week, so I wanted to follow up with creators on the platform. So even though you didn’t reach out to us, we had others that reached out, so I wanted to make sure that we heard directly from creators about what their concerns would be and so that’s really the reason I set up this call.

MATT: Sure. I’ve definitely got a lot of notes and a lot of questions that I’d like to ask. I wanted to begin by just noting the scale of the loss on my account, if you’re comfortable with that.

JACQUELINE:: Yes. Yes.

MATT: I did the numbers this morning. I am down 39% of my total patrons, 42% of the money on my account. I’ve been on Patreon 2 years and 3 months now, so over 2 years of work on Patreon at stake here. I don’t know for sure - I’m estimating that roughly an entire year’s gain has been wiped out. Everything that I was able to grow over 2018 is gone now. I just hope everyone at Patreon understands the scale of the damage that the decision that they made has caused to uninvolved creators. And I hope you would understand why almost half of my patronage would leave given the decision that you made.

JACQUELINE: Yes. And that’s obviously one of the reasons that I wanted to set up this call, because - sorry, one small thing. I just wanted to make sure that we’re not recording. Like, I’m not recording on my side.

PiGI goes TTN - IoT Radiation Monitoring

At this point, 12 PiGI - Raspberry Pi Geiger-Müller Interface nodes are in active deployment at TDRM, helping to monitor the environment independently and so far reliably. Additional 12 nodes are on the current roadmap. That is a great success story and just in the spirit of the idea, development and open-source model of it.

Now the TDRM Working Group at Karel-de-Grote Hogeschool, Campus Hoboken in Antwerp pushed it even further and developed a LoRaWan based TTN (The Things Network) Adapter for the PiGI, to have it connected to the Internet of Things:

TTN PiGI Node TTN PiGI Node

This project was never intended to generate profit, but to free people from having to rely on government/military based radiation monitoring data. The incidents at Chernobyl and Fukushima showed very clearly how this data is suddenly unavailable or if presented, showing only measurements which can't be trusted, to calm people down.

PiGI was meant to be a cheap, available and easy to replicate solution, serving educational as well as practical monitoring purposes. Something to copy, not encumbered by old “intellectual property” ballast and secrecy. To spread and inspire new developments. Congratulations to the TDRM Working group, for succeeding admirably.
