How to find the best drinks for the upcoming "18 years of #realraum" party?
There is, in true scientific fashion, only one way: get many tasters and test, test, test 😅

Party is Saturday 2025-05-24 - Save the Date!

It's finally up as of yesterday. 😊

As you may (not) know, ChaosWest in Saal3 has an underwater theme this year, so we contributed a neon-jellyfish sketch.
If you spot it, you have found the Austrian Hackspaces Assembly A^13. Come by, say hi!

I finally hacked the beautiful #eh2024 #eh21 cyber-rabbit badge and turned it into something useful. 😃

A #homeassistant indicator light!
Which shows my flat's power usage!

Brighter lights with more blinking activity indicates more power, while below a certain limit it switches off completely.

I simply regulated it's power supply by tricking a step-down module's FB pin with an offset voltage using #esphome.

The whole hack is documented in the #realraum wiki wiki.realraum.at/xro:eh2024_ba

A collage of three different photos of the EH2024 badge in three different illumination settings (really three different supply voltages) as set via a homeassistant slider
the backside of the Easterhegg 2024 badge with the battery pack desoldered. In it's stead, a step-down converter is soldered on. The step-down is connected to an ESP32 devkit board.
the badge at it's final place where it shows my flat's power usage. Currently I am not using a lot of power.

Truly impressive detail, that I had not previously seen with FFF printers. Even more impressive that, what was basically a big block of support material after printing, could peel of witho9ut much trouble to reveal the figures beneath it 😃

printed in @realraum on a Prusa MK4 Input Shaper with 0.07mm and and a 0.25mm nozzle.

You are a programmer but you never wrote a lexer/parser? Join on 2024-02-06 at #realraum in #Graz. I will get you hooked in with small examples. We will write a simple lexer for a #LISP-like language and I will give you ingredients to build your own programming language in #python.

"Let's build a LISP lexer together" is a coding dojo with an introductory presentation before. pygraz.org/

Only possible because of the continuous work by @Dorianix and @roskakori for the python community. Thank you!
