I am doing "prior art" research to find out what are reliable and open constructions of sensors (and controlling/recording) platforms used in citizen monitoring of environment.

Due to recent events in Poland, priority topic is river monitoring:

• water temperature,
• pH,
• conductivity,
• dissolved oxygen,
• turbidity,
• ORP (oxidation reduction potential),
• water level (sonar?).

Also, typical weather station sensors recommendations will be appreciated.

If you know about an active group dealing with river environment monitoring, please drop a link here – I will be happy to learn from them.

At this stage, I do not intend to start any deep R&D. I need to learn about good (best!) practices and appropriate hardware, so we can deploy a network of early warning checkpoints as soon and as cheaply as possible.

I am now working on some simple pole weapon prototypes. Spearheads and other pointy ends are mounted in an axial groove, fixed with two screws. It gives an advantage, if we need to be able to change configuration. Other than that, we may need a permanent fixture.

My idea is to use non-protruding rods and to fill gaps with some kind od resin / glue. It needs to be elastic enough to wthstad vibrations and hits, while rigid enough to transfer force to the shaft.

Any suggestions?

This is my first try to add some spirit of adventure to boring TAILS reality. My thanks to all people – known and unknown to me – who provided parts and variants of this solution, guidance, and encouragement. No work is done alone. Attached please find a pack of simple scripts and guidelines how to install #Flatpak and #Signal under Tails. Solution is crude-ish, no integration with Gnome and scripts are spewing some warnings.

So consider it experimental and for fun only!

I plan to add some more apps (Delta Chat and Briar for starters) and also, thanks to your generous feedback, ;-) to improve quality from "daredevil" through "intrepid" and eventually to "boringly routine".

I hope you'll like it.

Morning coffee musings

Transition / Collapse solutions — how to get most out of collapsing infrastructure.

During slo-mo catastrophe, more and more infrastructure may become unused, but still technically working. This is what we have now with empty buildings / apartments for example. Or some abandoned industrial facilities taken over by their crews.

But there are more technical challenges. If the grid is down, what shall we need to redirect output of a local wind/solar farm to the local community use? How to start running local rail transport? How to salvage content of a logistic centre before it gets marauded? Etc. etc…

The inconvenience here lies in the fact that most of such actions are considered illegal under regular circumstances. But we will need them when conditions cease to be "regular". I believe we should be able to discuss them under the general category of "civil / civic defense" or "communal resilience".

What do you think?

Hi, We just started a fundraising campaign to buy our first boat, intended as a proof-of-concept for the WartaMAX project. It will be the first boat fully dedicated for Persons With Disabilities (PWDs) here in Poznań (Western Poland). It will also be the beginning of the process to introduce SolarPunk values into local communities across Warta bioregion.
