TACAN Panel for DCS F-14B Tomcat. Built with Arduino compatible microcontroller board Pro Micro, use with Flightpanel DCS-BIOS fork.
- 5V/16MHz Pro Micro Board w/ ATmega32U4
- 2 5mm LED for BIT result (GO/NO GO lights)
- 2 toggle switches for operation mode and channel (X/Y)
- 1 push button for BIT
- 2 potentiometer for channel selector tens and VOL
- 1 rotary switch(12 pos) for channel selector ones
The TACAN panel size will be:
- width: 5.75 (146.1mm)
- height: 2.625 (66.68mm)
I design the panel using FreeCAD. It consists of three layers. The bottom and middle layers are composed and 3D printed as a single object.
The top layer is either 3D printed then covered with a labels(legends) layer, or cut and engraved with a laser engraver.
Note the hole diameters are determined by looking at switches, buttons and encoders I have. They are likely to not fit for others.
Pro Micro has 18 digital PINs, 9 of which can also be used as analog inputs. This TACAN control panel will have about 20 Joystick buttons and 2 axes as inputs.
- TACAN Mode Selector and Channel Rotary Switches: use a single analog PIN for each switch.
