Making Korry-like Overhead Panel Switches, Part 1 – Revised Design

So I’ve placed orders for all the LEDs this morning. Expecting them to arrive in about three weeks. They’re coming all the way from China so I do hope they won’t get lost on the way. Still, it’s hard to opt for local dealer when you can spend less than 15 euros for all 400 of the LEDs, and the P&P is free. Unless you’re pressed for time (or hate long waits), of course.

First experiments with an Arduino and rotary encoder

While I’m waiting for a few parts to come to get going making those Korry switches I mentioned in my previous post, I thought I’ll take a crack at the basics of controlling the aircraft’s spead, heading, altitude and vertical speed using an Arduino and rotary encoders. It was tough at first but then I discovered the magic that makes it all tick. Continue reading First experiments with an Arduino and rotary encoder

Making Korry-like Overhead Panel Switches, Part 1

Korry switches dominate the overhead panel of an A320. They’re those push buttons with (usually) two LED lights, most of them with yellow FAULT light in the top half and white OFF light underneath it. Original Korry switches are super-expensive, and even those I found on opencockpits.com are no cheap for how many of these I’ll need. So I’ll try and build them myself… Continue reading Making Korry-like Overhead Panel Switches, Part 1
