Set 5 notes as of 2/2

Based on voronoi pattern with a couple extras

½ diameter with 3” long arm

A will be straight 3”

B will be straight 6”

C will be a v piece

D will be a bend piece (elbow) at 15d offset?

E and on will be as derived, to be ordered based off of shortest combined arm lengths to longest and each arm ordered 1 shortest, 2 middle or equal length and 3 longest.

Sample objects will need to be made to allow for testing. We should have 5-10 samples for each test. We will largely be looking at stress and strain on the instron. The jaws for holding a sample are .25 wide Our nominal thickness is .5 so an adapter is to be molded, there will be two variants. We can produce molds for both. These molds will work with other materials too.

Actually…. Now that I think about it I’m going to make it so that the molds for our test cores can also serve as unit A and B (detachable end caps.) Since we will need to make many molds for both this will save a lot of time hopefully.

We are hoping to get some funding through our school to help cover some costs, waiting on word for that and in the meantime taking calculated risks. We will need to order more materials soon.

We are meeting with school staff next week to find a way to uniformly grind our substrate (in the case of mycelium) so we get a more dense output.

Starting to think of layout format for communication of designs (spreadsheet)

Going to start working on our final documentation in a mostly chronological way following along with the hackaday page and creation and edit dates of various documents and files.

So, as an example; the blog post would have a thumbnail and link (evidence of the work) and quote or overview with more elaborate documentation (go back to dated files and screenshot for example) Weave the links, mention meetings, people and places, inspiration along the way.

Testingmolds2bonus is both A, B and the testing units in file directory (internal)

Took me three tries!

We tried some fillet variations for the primary module set and ran into some errors so that is being redone. Ultimately it looks like we are going with a minimal chord length based fillet. This might change however if we can find a smoother transition which does not cause molding/demolding problems.
