Collaboration Tools

We choose FOSS options whenever possible. Please keep in mind that all of our infrastructure is provided by people that do this service just for fun, the heck of it and because they wanna help. So there is no SLA or anything. Please do not rely on a single media and have backups. Any service might be just gone for some days, please keep this in mind for all time.

Please feel very invited to provide us more infrastructure and tools!

Tools for Workshops and More


There are some blogposts, more coming soon!

But in short: We have multiple Thinkpad X60 laptops for workshops and coding, and we have some soldering irons, desoldering, hot air stations, variable power supplies, multimeters, assorted e-waste for repair/repurpose/component salvage, breadboards, some IC's, transistors and other components. Also we have a ground stock of hand-carpentry tools. This time we also have a microscopy :)

Other tools

CCC tools

At c3 we already have some tools already developed, like

  • pentabarf/frab for programme planning,
  • for organising shifts of volunteers
  • a purchase-tickets-system plus the whole backend of cash flow around

I will try to find out how and which would be useful for us, and if those (volunteers) are willing to provide us those services, too.

Hasgeek tools

Hasgeek has this thing called eventframe:

Doodle we can use that one instead of centralized services. Provided by a friend of sva.

Pastebin again we can use that nstead of centralized services. Provided by a friend of sva.
