Hardware & Technical HOTAS: Razerduino (Razer Tartarus + Arduino)

[CMDR something]

Thrustmaster T.16000M FCS would have been my favorite. But.. not available until... *fuc#x@x#**!

--------------------------------

So I took my time, did some google search for "Arduino" and "Gamepad". Result: YES. Possible. That was 10 days ago.

The Idea: Build a thrust controller with an Arduino and put a Razer Tartarus keypad on top of it. A Razer / Arduino sandwich.

Lots of buttons and thrust control, all on the left hand. Probably better then any commercial HOTAS.

This is the final Razerduino:

Thrust control via linear fader and a couple of extra buttons.

How did it start?

Here is the first prototype:

Some wood and 2 linear guides as used in drawers + Arduino Micro (USB capable 32U4 controller) and a 60mm fader. Arduino acting as a gamecontroller. Fader goes to X-axis of gamepad... Simple.

Put the Razer Tartarus on top - and we have a keypad/gamepad sandwich. Actually a HOTAS:

In the final version the Arduino got some extra buttons and a LED (green for zero throttle, blink for reverse).

What to say.. I have no need for Thrustmaster, Saitek, CH.Products... anymore.
My First Class Passengers like the smooth ride. As well, as I do [up]

Build your own. It's Open Source.
