Most of my time this week was spent on reiterating on the module design and also working on the ethics assignment for our team. The latter is self explanatory, so I won’t go into any detail for that.
I finally got the snap feature for our caps designed. I followed these youtube tutorials for guidance
This is a cross section of what our module and the holder design looks like after I made the changes in CAD.
As you can see, the top piece has been developed significantly and there is now a angled latch feature. Hopefully the margins are right for it to attach securely, but I guess we’ll see after printing. I also last minute added some impromptu ledges (those rectangle blocks halfway up) so that we can fit another protoboard. I think we might want to make the modules shorter, but I’m not sure how much we can without it getting too hard to physically configure the wiring of the electronics inside, since we need to do that by hand.
Otherwise, another change I made after seeing last week’s iteration printed out is make the holes for the pogo pins larger. Last time there was not enough margin to fit them in, hopefully it’s better now.
I’m still pretty behind schedule on module design, this is taking longer than I expected and waiting for a design to get printed before reiterating on the design to make any requisite changes is time consuming.
Next week, I plan on continuing to reiterate on the module design. I think we should be finalized on overall design, just need to see if any fixes need to be made after this gets printed. Next, I need to work on making specific arrangements so that each type of module can be inserted appropriately and stay there. That will likely take more trial and error.
