DIY Knobster - First Experiment

Here is my first experiment on the DIY Knobster build for Air Manager. It's my first time using an Arduino and in general doing this kind of electronics project.
Hardware in this project:
Arduino: store.arduino.cc/usa/arduino-...
Dual encoder: www.propwashsim.com/store/dua...
Resistors: www.sparkfun.com/products/10969
Jumpers:
- male-to-male: www.sparkfun.com/products/11026
- male-to-female: www.sparkfun.com/products/12794
Air Manager DIY Knobster page: siminnovations.com/wiki/index...
Sketch source code and board wiring schematic are available on github: github.com/peterlanoie/arduin...

Wow, just what I was looking for. Thanks for all the work!

And it helps indeed, thank you for all this very useful information Peter!

Great video and explanation. Just got AirManager, so this is next.

Google how to handle a rotary encoder with D-type flip-flops. You need two flip-flops per encoder, but that's fine because you can get a quad flip-flop in a single IC and it will handle your two encoders. This will translate the rotation of the knob to look like button presses on two wires (which can then be assigned to the "up" and "down" commands for an instrument).

I like it

I have built several DIY Knobsters using the same encoder and never included any resistors and it seems to work fine.

Agree with you here , 100 USD for a nobe and USB cable its really too expensive to have it 😅

Hey Peter, debating if I go this route or buy the knobster. Technically, if I hook up the wiring as you have it in part 2 (5 connections as you mentioned) from encoder to nano and nano to PC via mini USB, that's all I need right unless Propwash decides to change the connectors, correct? The breadboard, led's, resistors complexity is giving me a pause and I am wondering if it's really needed if my thinking is correct. Also, at

Hi Peter, thanks for your video!

[@angushorlock7776]

Might be a long shot but is someone able to provide a part number for the rotary encoder switch itself please? Trying to source in Australia as getting the kit shipped to AU is going to cost $50 which is crazy for such a small item!

[@iainathairydog]

It'd be lovely to do this. Unfortunately, buying two encoders for $12.50 is fine, but paying over $50 to have them posted to the UK is a show-stopper for me,

I have it ready to go but how do you configure it on msfs???

[@dundeepolice991]

I trade you a 2nd hand GFORCE RTX 3060, for a knobster that works.

I make about $300 a day, this would take me days to figure out, for me the knobster would be more viable.
