Points Discussed:
- Presented ideas for seals on test tubes
- First idea - pizza
- A full lid that rest 1/16th above the test tubes
- Pros
- Simplistic design?
- No hooks
- Cons
- Limited motion of mixing?
- Second Idea
- Similar to old design
- No center pole
- Lid rotates to expose 1 tube, as needed
- Pro
- No hook aka no binding
- Good seal
- Con
- Seal potentially may be overkill/unnecessary (may be toned down so that it’s just a cover)
- Funnel top + First Idea
- Funnel top helps dirt stay in the test tube even more
- Pros
- All passive
- Secure
- Cons
- potentially limits flow
- Needs more testing
NOTE __ CENTRIFUGE IS MIXER OFFICIAL NAME CHANGE??????? <_> >.<
Shovel
- Old Shovel
- Did not collect enough dirt
- New shovel - double shovel
- Theoretically collects more dirt, and also supposedly drops dirt more efficiently/smoothly
- Mount bearings to make motion more smooth
- Shovel is likely too big (when considering the amount of dirt that would be picked up)
- Difficult three D print
- Prototype needed
- Linkages need to be tested, shovel can always be changed
- Moment calculating needed
- Chain for elevator mechanism or Tensioning Belt
- Need a camera on mech to see test tubes to analyze
