12-29, 13:00–13:15 (Europe/Berlin), CDC Triangle
We meet indoors at CDC Circle and go outside to launch some comms infrastructure on a tethered balloon.
As every Star Trek fan knows, humans are "ugly bags of mostly water" [S1E18] so RF communication in areas densely packed with humans - or their infrastructure made of metal and stone - is problematic.
We'll explore ideas to overcome or mitigate this problem, ideas that are possible due to miniaturisation of RF devices and their constraints.
Humans are ugly bags of mostly water and they and their infrastructure attenuate the RF signals we need for communication.
We'll explore concepts that are possible due to miniaturisation of RF devices and their constraints. In the end we'll raise a tethered balloon with Meshcore and a Reticulum node indoors or - depending on the situation - outdoors and playfully check the range we can achieve.
We'll discuss
- what we trying to achieve / the problem at hand
- the physical, electrical and financial constraints of our solution compared to other approaches
- what changed, why can we do this in 2025 but not in 2015?
In the end we'll raise a tethered balloon with Meshcore and a Reticulum nodes indoors or - depending on the situation - outdoors and playfully check the height and range we can achieve.
This is a fun workshop that wants to encourage people to play with compact yet easily deployable communication infrastructure, there will be some basic maths and diagrams, but nothing intimidating.
Chris has had no Ham license for decades, mostly because there always was something else eating up his time. But next congress, definitely.
Chris does not expect the fall of civilisation and would not consider himself a prepper, but being able to communicate if centralised infrastructure is not available for a while seems like a good idea and the real treasure are the friends we make on the way.
