+  * 2025-10-18, 19:00: **Meshtastic**\\ //Herbert Lange (University of Gothenburg)//\\ [[https://meshtastic.org/|Meshtastic]] is a license-free¹, open-source², encrypted³, off-grid⁴, radio mesh network⁵ on top of LoRa⁶. It is popular because it is very open and the hardware is cheap. It can be both used to communicate from person to person or in automatic applications, such as sensor networks. In this talk I will give some technical background and explain all the necessary concepts (¹-⁶). I will also tell you about my own experience with the technology so far and how you can get started yourself.\\ {{2025-10-18_meshtastic.pdf|Slides}}

-  * 2024-11-02, 19:00: **Drawing with sound – From drawing mushrooms on an oscilloscope towards driving a plotter**\\ //Herbert Lange (University of Gothenburg)//\\ For quite some time, sound has been used to draw animations on oscilloscopes. That has even led to the creation of oscilloscope music, sounds created to both generate appealing visualisations while at the same time being musically pleasing. The basic idea is that sound can be represented using voltages which can be visualised on measuring equipment such as oscilloscopes. In my own project I want to explore if similar techniques can be used to drive a voltage-controlled plotter using a small TURTLE-like language.\\ {{https://wiki.dfupdate.se/_media/projekt:2024-11-02_drawing_with_sound.pdf|Slides}}

   * 2024-03-23, 19:00: **Forth — your favourite programming language that you don't know yet**\\ //Bjarni Juliusson//\\ The talk introduces Forth, a curious programming language that quite possibly doesn't look like any other language you have seen. Despite never quite making it into the mainstream in its 54-year life so far, it has made it into space on several occasions, including on the ESA asteroid-lander Philae, the NASA Saturn probe Cassini, and the Swedish satellite Freja. Both a language and an interactive development environment, Forth takes a minimalist approach to syntax (there isn't any) and provides maximum flexibility for you to develop your own application-specific languages very close to the hardware. It's hard not to like it!\\ [[.:updateringar:2024-03-23-forth-bjarni|Code]].
