Working Bridge for RC Ship 1:50 Scale

I am building a 1:50 kit of the Happy Hunter RC tug. As usual, I am making it far more complicated than it probably needs to be!

I am currently getting the internal electronics sorted out. This lead me to decide on a working interior for the bridge.

That, as it turns out is more difficult at this scale than I expected.

I decide to try and use materials I already had, so I dug around and found some 128x32 OLED screens.

I needed a small processor, and had some ATtiny1606 processors, so they will do fine.

To give me more I2C output ability, I added a CD4051 multiplexer.

First job was to design a PCB and a 3d printed interior for the bridge.

Good old Tinkercad was fine for the 3d design. I managed to find some free 3d STL files of construction workers online.

I adapted these to become deck hands.

Once designed and 3d printed, I moved over to making a small PCB to control 3x OLED screens.

The CD4051 multiplexer switches the data on the I2C bus to the screens. This lets me run multiple screens off of the ATtiny1606.

Writing code for tiny radar screens proved interesting. That isn't a whole lot of pixels to work with!

The screens display various changing screens and sweeping radar graphics.

The PCB actually has the ability to run 4x screens, but I just could not fit them in.

Random flashing leds were hidden behind the ships console (that was tight for space!). From these leds, small runs of fibre optic strand were run out to make indicators on various panels.

This control PCB also had 4x outputs for amber leds that strobed in a sequence. These will later run a rotating beacon out on the deck when the loading crane is operational.

I printed out a whole pile of vinyl graphics for the various fake monitors and desk panels.
