Our next 3d fab meeting will be on November 2nd, we will be discussing the scanner, expansion and a possible solution for filament theft. Elections will be held and hopefully there will be cake

For anyone interested in running for chair, please formally announce your intention to run, so that you may be added to the ballot.
Currently @maxk68 is the only one to announce an intention to run for chair.
Since when has this been the case? In the past that’s the way things went. Even if you didn’t show up, you might be elected as chair. That’s happened before.

This is not a rule. Anyone can run and not give advance notice.

Now if you show up with 300 proxies, that’s likely to be thrown out.

As the others have said, this is not a DMS rule, nor is it a committee rule.

- Is the cake a lie?
- Thank you for all the hours you’ve put into 3D fab. Between the classes and office hours, you’ve always been willing to help. I wish you the best in the election.

Ah, well thank you all for correcting me. From the discussion we had at the last Fab meeting I was under the impression that cold show to run was not allowed.
ultimately its up to the board so I day just go with the flow
I don’t know what you ideas you plan to discuss to combat filament theft, but I thought I’d pass along an idea I had while I pondered the issue. I think it would be possible to build a “vending machine” like structure, that has individual slots for the filaments rolls. On the front would be individual clear Plexiglas doors that are hinged on the top and have individual magnetic releases. On the bottom of each slot, you would have cradle for the roll (could be 3D printed) that mounts to a load cell capable of weighing the filament roll. On the front would you could have an RFID reader and a keypad.
This is how it might work. All doors would remain locked until a member swiped their RFID card/tag at which point they could select which door to unlock. The spool in that slot would be weighed (using the built-in load cell) and the door released. The door would remain unlocked until the user was finished and the spool returned to the slot. The door would then be re-locked and the reduced weight recorded. Now you know who checked it out and how much was used. You could get way more fancy, but I won’t go there.
I’ve spent all of about 10 minutes on the drawing below to provide some idea of what it might look like but you could do it however you wanted.
2kg load cells and a load cell amplifier can be purchased for about 5 bucks for the pair.
Magnetic locks are less than $15 each.
RFID readers and keypads are cheap and an Arduino or Rasberry PI (or whatever) could control the thing.
I would bet this could be built and programmed in a day or two with some planning and a team of 3-4 people. (1 programmer, 1 mechanical designer, 1 electrical designer and maybe 1 woodworking/laser person.)
If this idea is something that perks your interest, let me know and I can do a bit more investigation and better estimate the cost.
