Idea of doing a short show and tell of projects at the beginning
problem: Acquisition of presenters -how to solve?
- Mitja: We should just try an open slot and if volunteers are there, let's go

Today's volunteer: Joel - Project:Robot Arm

It's there and beautiful!
unfortunately the radio signal at the new location is poor, there are random blackouts (loud crashing noise)

Discussion about getting a new bandsaw ongoing
Current bandsaw is on long-term loan and not suitable for resawing thick planks
Need someone to identify a suitable model
Financial constraints make immediate purchase unlikely
Gathering interest and willingness to help with funding suggested
Mention of a potential model: Holzbandsäge MJ14 from paulimot.de
Mention of another potential model: [Premium 12" Bandsaw from recordpower.co.uk]
Suggestion of considering a second-hand bandsaw for cost savings but concerns about maintenance and quality
Alternative suggestion of building a bandsaw ourselves using a DIY guide from woodgears.ca --> difficult: takes a lot of work and might not be safe/durable in the end!

new option: bundle of machines from the university for 5000 €

the bandsaw alone (Mössner Rekord 320, 210 mm workpiece height) is worth about 3500 €, a big CNC mill worth >30000 € refurbished
where to get the money (quick)?!
- betterplace donations! Keno could already prepare a campaign
- kickstarter style campaign with "rewards" like xy laser minutes?
- Privatdarlehen to buy time?
- can we somehow sell some old machines, perhaps via a reseller who will take care of refurbishing? Especially the large CNC mill might be too much for us
  - other CNC mill/router are under-used due to difficulty and lack of documentation
  - is there enough power (400 V, probably 32 A?)
big question: how long until we have to decide?

Description of a plasma cutter as a tool for cutting complex geometries out of metal plates
Cost estimation of a plasma cutter at around 300-400 Euro
Suggestion of a YouTube video showcasing a mostly printed CNC plasma cutter
Discussion about the absence of volunteers to maintain the CNC
Inquiry about the usefulness and price range of a plasma cutter
Criteria for acquiring new tools discussed, including financing, maintenance, and impact on the space and other tools
Agreement that a plasma cutter could be considered if the criteria are met
Previous focus on the welding area before considering a plasma cutter
Mention of advantages of a plasma cutter for building molds for Precious Plastic
Suggestion of considering a cored wire welding machine for advantages in the metalworking area

today's opinion: nice idea, but not a priority
- the welding area is still not usable, which should be taken care of before the next diy machine
- the current machine offer (Topic 2) would probably bind the available resources (money and metalworking experts) if we decide to go for it

Date: Sat July 8th, 14:00-18:00

we need helpers: organizers (mainly need to know their way around the Space) and/or repairers!
- Ökostadt Rhein-Neckar (main organizer) collects volunteers in this Google Sheet
Rolf will see whether he can do electric checks again
other members present are probably not available
please join the interest group on Slack: #topic-repair

minimum duration 4 h (can be split into several dates), 20 participants per event
full requirements: conditions of participation

Keno thinks he could find several KI tutors from his work
Keno could also do git and Python primers for sure
Koen has a computational modeling workshop in mind
further ideas welcome! Let's discuss everything and write applications for several worthwhile concepts :-)
