Messages at the Systema Solar Concert

July 05, 2025

During the presentation in Barcelona of the Futurx Primitivx 2025 album by Systema Solar, I configured a LED tag name to share some messages. Here I present the messages and how I configured this little device.

The Messages

First the Video

Here's a video with the LED tag name and the list of messages.

This video is also available on Wikimedia Commons as Systema Solar LED tag name.

Now the Messages

The messages are in Spanish, more or less says:

  • Berbenautical Colombofuturisms
  • Gatherings with affection (Here I am using slang)
  • Ecofeminisms #DaleLaVueltaMama
  • Return the Quimbaya Treasure
  • Well, so what? What's the issue?
  • Taganga power
  • Return to the jungle
  • Systema Soooolarrrr! Fine champeta
  • Teusaquillo power Bogotá affection (Here I am using slang)
  • I brought nothing, I take nothing (-_-)
  • I cannot forget

How Did I Do It?

I got the little device at Wikimania. I didn't know what it was called, but over time I found out its name is LED tag name and there are people who sell it.

Then, the problem is that they came with Windows software, but I use Ubuntu. I found this GitHub repo that synchronizes LED tags with messages. You have to install some software packages but in the end the synchronization is done with Python. I don't know why, but the device never worked via Bluetooth, only by cable.

The code I used was this, being in the Badgel software folder that I downloaded:

sudo python3 ./led-badge-11x44.py -m 0,0 -s 6,6,6,6,6,6,6,6 "Berbenautical Colombofuturisms" ":heart2: Gatherings with affection :HEART2:" "Ecofeminisms #DaleLaVueltaMama" ":bicycle: Return the Quimbaya Treasure :bicycle:" "Well, so what? What's the issue? :happy2: :happy: :happy2:" "Taganga power Return to the jungle" "Systema Soooolarrrr! Fine champeta" "Teusaquillo power Bogotá affection I brought nothing, I take nothing (-_-) I cannot forget"

The message limit is 8, but to include more, I simply put some spaces between message and message. Let me explain the code a bit, but the full documentation is here:

  • sudo python3 ./led-badge-11x44.py: as super administrator you run the Python software that includes the messages.
  • -m 0,0 -s: the message goes from right to left. m is for mode and s is for speed.
  • 6,6,6,6,6,6,6,6: is the speed, from 1 to 9, of the messages. Speed 6 is like medium-fast, because I wrote extensive things.
  • "Berbenautical Colombofuturisms": Then come the messages in quotes separated by spaces. I used :bicycle: to get the bicycle, :heart2: and :HEART2: for hearts with and without fill and :happy2: and :happy: for happy faces. To one of the messages I made an emoji with parentheses and dashes: (-_-).

One of the problems I encountered is that it's developed for French characters. Therefore, some accents and openings of certain signs don't appear or generate errors. That's why I wrote Bueno y que? (the message meaningWell, so what?) and I couldn't do it with signs and accents as it should be with a proper: ¿Bueno y qué? using ¿ and é.

If you want to replicate it, share it, so we can see what other tricks we learn.
