This is a USB connected "Button Box" intended to emulate the buttons of the LX9000 module by Got-Friends as used in flight sim gliders. It consists of 4 rotary encoders and 8 momentary buttons in a layout similar to that of the LX9000.

The rotary encoders are HW-040, and the buttons are K081a040, and they're all wired to a Leo Bodnar BBI-32 board.

Materials: 1 x Leo Bodnar BBI-32 board: leobodnar.com 4 x HW-040: aliexpress.com 8 x K081a040: aliexpress.com 4 x 6mm M2 screws: aliexpress.com 8 x 8 by 3mm Round Rubber Bumpers: aliexpress.com 1 x USB-B (printer) cable: aliexpress.com

And to answer the question you're all wondering... The reason it's "so red" is because that was the only colour of button I could find of the right size, so I just kind of went with it as a theme. You, of course, can print in any colour you please –even if it's not as nice as the red: 😉
