Tools Info
One day in Jan 2016 an enthusiastic brand new member was working on a project and asked me how I would cut something accurately. We had a talk about the options and we looked at the bandsaws one by one - they were all out of order. I tried to find out about the various statuses online and where I could find/get spare blades The wiki tool lists are out of date (understandably!) and not maintained (e.g. Tools/We_Have has no mention of 4 of our bandsaws) - searches find lots of old pages that nobody needs.
What people want to see is a live status page for the major fixed-down tools - the tools team can keep this reviewed and up to date. For reporting problems, I'd like to see a quick means that doesn't need a computer: -
- Have a physical rfid box with say 6 buttons on it.
- Member scans Rfid and presses button for broken tool.
- Magic happens and tools team is informed via slack.
- Member can be emailed for more information
- Website hms tool status page is magically updated with red cross against tool
- Github issue is magically opened to track the problem
Bandsaws
