My FSBUS Console
Suomeksi
I am a PPL license student at the moment, so my goal is to create something
that helps me practice my flying skills with Flight Simulator as much as
it is possible. Having real feeling knobs and switches makes learning more
efficient since you will have all the familiar things to poke at as you have
in the real plane as well.
So far I made a "box" out of plywood that houses most of the stuff, but eventually
I am thinking of building some sort of a more integrated console, perhaps
not a real enclosed cockpit because of space restrictions :-) but maybe something
that contains the FS instrument panel on a monitor behind a "hole" panel,
has all the needed knobs and switches within reach and thus makes using the
keyboard unnceccessary.
I am also building a yoke and pedals at some point. The yoke is in a prototype
stage where it basically works but looks pretty hideous :-)
Prototype Cessna control panel with FSBUS and Joystick electronics
This is how it looks from inside. The stuff on the left is the FSBUS COM-card
(the smaller one towards the back of the console) and the one on the front
where all the wires spaghetti goes into is the "KEY" card which hosts all
the switches and routes their signals.
The panel guts and bone from inside...
The throttle controls are made as a joystick for now, since as far as I know,
the "8 analog axis" -card for FSBUS is not completely finished yet.
From the left to right you can see the following:
- Magnetos/Starter switch (yeah, OFF/RIGHT/LEFT/BOTH/START like on a
real plane. You mean you dont start your Cessna with a key in flight simulator?
:-)
- A rotary switch and a pushbutton (the black ones) will eventually control
radios, those are just placed there for now for testing purposes. Rotating
the knob changes the radio "standby" frequency - and pushing the button switches
it active just like on a real radio. The challenge is to construct those
two-knobs-inside-each-other -things, but I might just do separate knobs for
the whole MHz and the fractional part. Or just make one rotary increment
the whole frequency. Still needs testing. Special components called "rotary
encoders" from www.knitter-switch.de
can be used as well as specially wired "normal" rotary switches. Still trying
to hunt down knitter encoders within Finland, it seems to be a pretty challenging
task. Sometimes it sucks to be just a hobbyist and not a huge electronics
factory that makes component salesmen bow at your feet.. :-)
- Switches. Eight for now. For master battery, alternator, pitot heat,
landing and panel and navigation lights, beacon etc.
- Trim wheel. Right now it is just a potentiometer set sideways and glued
into a wooden wheel. Eventually I am going to do a real-life sized trimwheel,
and might even make it just adjust the yoke center point - that is how those
work in reality anyway (or that is how they feel when in flight)
- The yellow knob is the carburettor heat knob. It is done with a reed-switch
(a small glass tube that makes contact when you move a magnet close to it.
The magnet is in the green heatshrink tube that is attached to the wire.
When one pulls the thing, the magnet moves close to the reed switch, when
you push it back it goes away. Works but needs some thinking to get a realistic
feel, right now it doesnt feel heavy enough, it wobbles too much.
- The throttle and mixture controls. These are made from 5mm steel and
(yeah right) soft drink bottle caps and real wine bottle corks. All neatly
superglued together :-) On the inside end of them is bicycle brake cable
that moves a lever that turns a potentiometer. And as I mentioned earlier,
these are technically a joystick. You can see the white cables go to a joystick
wire through the white block connector thing.
- The last thing on the console is the flap switch. It is constructed
with microswitches. A detailed photo is below.

This is what I have so far. Updates will be posted on this page as they appear.
