Onboard computer
A computer with a touchscreen and expansion modules to switch and monitor everything on board, with software of its own: BKOS. In development since 2022.
I am Brendan, a hobbyist in electronics and 3D printing. I learn by building, preferably things for my boat, and I share everything I make. Build what you like, or tell me how it could be better.

What I make you may copy and improve. Only commercial use stays with me.
You may download, build, print and have made the software, schematics and 3D models for your own use, not for profit. Adapting it to your own boat is free.

For a fair price I can help with electronics and 3D printing challenges. From a small change to an existing design to a one-off gift.
