im back from exams and the full shifter is finished!
added the limit switches and slots for each of them to be glued down when i build it.
the pcb has also arrived, now all i need is to buy the components (hopefully can get them hardware funded) and 3d print the rest of the components (hopefully can get that funded too cause i dont have a printer)
exported a 3d model of the pcb from kicad and added it into the cad model with mounting hardware and mounting holes. also created a shift knob that has an m10 internal thread so it can be screwed on to the threaded rod.
will be slowing down a lot over the next week and a bit because i have a full week of exams - but will come back with more updates than ever afterwards!
main pcb designed and routed using an atmega32u4 and through-hole slots to wire each momentary switch to the board individually :)
if anyone sees mistakes in my pcb - it would be greatly appreciated to point them out for me as it is my first time making one!
update: the pcb has been ordered!
finished every mechanical mechanism for the shifter! used a roller cam-on-center mechanism to simulate the tactility from a real h-pattern. added some colour to the 3d model as well. next up is the fun - but stressful part, electronics!
looks like i finished the first revision of the centering mechanism, using springs on each side of the y-axis movement mechanism to be completely balanced in the middle of the 2nd and 3rd gear column. now, as the actual movement is finished - now i need to add a bit of tactile feedback - probably with cams or a dedent mechanism. :)
finished designing all of the main mechanical parts and final rotational mechanism of the h-pattern shifter using axles and bearings. now time to model some centering springs and maybe research into a dedent system for a better mechanism feel!
started and finished the designing for my first revision of the shifter shaft and shift plate :)
most of the time spent here was in obsidian taking notes and designing with excalidraw, but i think that wakatime didnt pick up all the time on obsidian - but doesnt matter cause i spent a lot of time on onshape anyway!
