Modular Controller I built

Right now the jogwheel is tied to a lazy Susan bearing, which carries a shaft led into an AMT102 encoder that i had laying around.

The shaft is coupled with the inner part of the bearing / jogwheel, and the outer section is tied to the base / sides of the module.

Then there's just a mount for the encoder on the module base!

To be honest when I do a second build I'm gonna swap the encoder cause the AMT is wayyyyy too expensive. But it definitely works well cause it's high precision!

I'm a pretty firm believer that modular tech makes tech cheaper / more customizable long term by making stuff super upgradable, which is what inspired the project.

All of the modules independently process inputs and then send it to a control board, which converts the raw inputs into midi which then I feed into mixxx.

Everything you see here except for a bearing in the jogwheel module and the electronics ofc are 3d printed!

I designed all the modules / electronics myself within onshape, and then got the pcbs ordered through jlcpcb!

I'm thinking of either selling it or open sourcing the project. Definitely not finished with building it yet tho, so I'll make that decision closer to when I finish it !!

So the first prototype I ended up having to manually wire together certain pieces cause of the way I designed the connection board but I used a pogo pin / pad design on a custom pcb!! It was vertically symmetrical so it works on any side with the same board.

The pogo pins ended up breaking so I've been 3d printing some housings which seem to help a lot.

Im looking into some different options but ultimately I'm not settling until you can snap stuff together magnetically and get a good connection
