As the "old" Fire Panels now are sold SE-BOH will reinterface Cockpitsonics Cargo and Engine Fire Panels via a Pokey Card + LED Extension card from
Other hardware in the sim:

Motorized RSP B737 TQ
Full 3-row Center Pedestal with ACARS Printer
MIP fully interfaced with gauges, Full sixpacks and Glareshield.
Full FWD Overhead Panel with returning solenoid starters (Cole switches), AC/DC panel, Pressure Panel and all gauges interfaced.
ACE B737 yoke, pedals and Ground Steering tiller.


ACARS now in own dedicated page !
This as the "how to" explanations how to set up Hoppies ACARS need more room.
SA_WXR radar simulation which worked ok in
PM is now decommissioned as ProSim has a radar simulated.


The old MC Intercom is scrapped and I invested in a USB soundcard dongle (Deltaco) for amazing 6.50 €
This supercheap solution gave me full intercom between CPT and F/O.
A two way splitter cable on the headset side also gives audio via a pair of powered comuter speakers.

FWD Overhead SE-BOH

All wire run via 9 lines flat cables in U shaped alu "rails" to the FDS SYS1x card situated on the OH "lid" togeather with Servo and relay cards.
Gauges are Open Cockpits and backlit by attaching four 3 mm LEDs to each gauge (= 12V over a dimmer circuit)
Panel Backlight is now changed from white to Amber/Yellow. 5 meters of LED strips hooked up on a dimmer.

The annunciator LED:s are soldered on a piece of experiment cards since Poldragonet OH does not use annuncioator holders.
All LED:s are flat top HI-Brite LEDs with 120 degree light angle (bought via eBay from Hong-Kong).

The AC/DC panel is, at the moment, only eye candy with fixed green 7 segment led numbers when BATT SW is ON.
The Cabin Press panel has a fully working controller and software from our friend Pim van Vrijaldenhoven in Holland..

The TQ/Radiobox floodlight is made out of LED:s and their holder from a 4.5V dismantled LED hand torch attached to a dimmer.
24 mm in diameter and 15 mm thick assembly mounted in a Lexan frame.
As "a bonus" the rear end of the torch looks exactly like a real Cocpit Voice Recorder microphone (can be seen in the picture)

Dual solenoid equipped starters are now installed. 100% working like the real B737 Cole switches.
A genuine B737 APU starter switch is also installed and all essential ON/OFF switches changed to APEM 5000 series lockable switches.

Approximately 60-70 hours was used for fitting all electronics in the OH.

Now Yellow/Amber color since April 2013 :

SE-BOH Overhead Backlight on


SE-LEH Overhead


Throttle Quadrants

Both sims are now equipped with Motorized B737 TQ:s.

SE-BOH has a RSP TQ with motorized speedbrakes, throttle handles, trim motors and working trim gauges.
SE-LEH has a similar Poldragonet / FSC TQ.

"Assorted" Tech Solutions

SE-LEH and SE-BOH Own made Sixpacks with Recall



Tiller assembly on sim outside

Simulator pneumatic lifters ( - one in each corner )



SE-BOH Overhead Panel welded steel stand. Center part = front window center post.

Yoke assembly

SE-LEH New coupled Yoke system


Framework under the cockpit:

The frame is welded steel and the corners have a "compressed air lifter", the latter for future "movements" of the cockpit.


Aileron potentiometer assembly:


Sim Control Panel (for Center Pedestal).
The CHKL (integrated electronic checklist) does not work anymore as it was designed by TSR for Project Magenta.
ProSim has integrated push-back in their CDU program so eventually this panel will be obsolete.


Center Pedestal for SE-BOH

Now a 3-row fully equipped Cockpitsonic Center Pedestal has replaced the old 2-bay CP Flight equipped one.
An 80 char thermal ACARS Printer is installed with a specially ordered panel from Hispapanels.

The Engine Fire Panel in SE-BOH is now changed to a Cockpitsonic
panel which will soon be interfaced by a Pokey card.
The pictures below shows the old one based on Open Cockpits panel and with home made handles.

The real thing:

Full functionality will be achieved through Pim van Vrijaldenhoven software and Phidget 8/8/8 card.


MIP "Placards" :

We have made the MIP (and other parts) a bit more real and lively by adding printed "placards".
There are no exact science on placing them, but CAA requires some of them to be attached to the MIP so we made a printed adhesive sheet :-)


Computer Setup :

As of August 1 st 2013 Project Magenta is out and ProSim 737 is installed.
Mainly the same computer setup though, a newer schematics will come when time permits.

SE-BOH now have four Shuttle-XPC computers installed - 3 dedicated for ProSim and 1 for VATSIM / EFB /ProSim Control app. All use 32 bit WIN XP.
They are excellent for the sim since very small (shoebox size) and quiet.
We use "bottom line" 50 € Nvidia graphic adapters in those since no need for sophisticated hi-end cards.

ProSim "server" and FS however need a computer as fast as possible so SE-BOH uses a I5 "K" series Ivy Bridge overclocked water cooled computer ( 4.5 Ghz).
Another computer in the LAN is dedicated as Instructor Station, Dispatch Station and common system work station via TeamViewer.
So, all in all 6 computers in the sim. ( ProSim Instructor station can be controlled via a smartphone or I-pad too with WIFI connection to the LAN. )


FS9 and MCP run on the "server" - a fast PC.
ND and EICAS on dual screen (WIN desktops) Shuttles,
Upper EICAS is displayed on a 15" TFT, Lower Eicas on a 10" screen, PFD/ND on a 17"WS TFT and the CDU display on a 7" VGA TFT.
CPT EFB uses a 10.4" touch screen and F/O EFB (cloned) uses a 17" touch screen.
Switching between ACARS and normal CDU is done with FSUIPC/WideFS "SendKey" which gives a focus change between the two. CDU Keyboard is shared.

CP Flight "Old Modules" users - Look here !

Their size is non-standard, and give problems when you have a standard B737 "Radiobox" (Center Pedestal)
Retrofitting is very easy, but requires you to use the modules without the metal cover in the back.
To get the size right for the Center Pedestal the original CP panels can be cut in the sides and also remove the metal box enclosure. See the picture above where an original "old" version CP Flight ADF is mixed with Open Cockpit NAV and CP Flight new Transponder and COM1 modules. The ADF front was cut down on all 4 sides.

Screen remote access

There will be MANY computers and screens and a KVM switch to run them from one central keyboard/mouse is a clumsy method.
There is a software solution available = TeamViewer which is freeware.
Via TeamViewer you can access every computer in the LAN from one computer/screen/mouse/keyboard and work remotely
on the connected computer (s) with ease.
TeamViewer can also transfer files between all computers.

Dual Controls without interconnected columns (SE-BOH):

With FSUIPC you can now have multi "joysticks" as well as the "ground steering tiller" connected and working even when attached to the same function.
The ground steering tiller inputs are gradually replaced by the rudder pedal inputs up to 60 KIAS when rudder inputs has full authority.


SE-BOH have two Cockpitsonic 737 replica pilot seats on "rails".
SE-LEH (see pic below) have two "retrofitted" Volvo seats on J-rails so they can move backwards/forwards and sideways to allow the pilots access without smashing the radiobay.


SE-LEH uses a modified Cockpitsonic unit with interconnected yokes and Cocpitsonic pedals which also will be interconnected.
Superb feel and forces after all modifications.

SE-BOH CPT side : Boeing 737 Yoke from ACE (Aircraft Controls Engineering) in Canada.
Great feel and looks! Aluminium die casted, heavy construction.
"Modded" with genuine 737 Trip Counter and trim thumb guard.

MIP Electronics:

CP Flights MIP737 card is used for MIP functionality except for FW and Lower MIP functions.
Very nice card and easy to set up.


Modified Rotary / Encoder combi :

New 45 degree rotaries arrived from Engravity and then we have made the center panel rotary/encoders combination.
(The "degrees" are the angle between the switching positions. A B737 A/B panel uses 45 degrees! )
Two of those had to be retrofitted with digital encoders - Speed REF and manual V1 - they both have adjustment knobs on top of the rotary switches.
Not easily available so we had to modify the rotary switches and fit the digital encoders behind them. See the pics below.


Software Programs :

ProSim 737 suite.
VATSIM clients
Top Cat Dispatch Program, Active Sky, Ultimate Terrain, FS 9.1
SIOC for RSP TQ. InterfaceIT for OH Panel annunciators and switches (SYS1x card)
PoKeys for both Fire Suppression Panels.

MIP construction:

The two MIP:s/CDU boxes/Glare shields were built with MDF boards on a wood frame support.
MIP back support is a 4 mm MDF onto which the 4 mm MIP itself is glued.
Sides 12 mm MDF interconnected in the back by 2 wooden L-shaped balks.

Glare Wings were cut out from hard foam plastic.
All instrument "frames" (PFD, Standby Instruments etc.) made of 4 mm MDF.

Electrical Power :

One standard PC 450W ATX PSU delivers 12 V and 5 V DC to the following:

Via 5 PWM dimmers : MCP floodlight, MIP floodlight MIP backlight, TQ backlight, Center Pedestal backlight (LED strips / LED:s).
Overhead Panel backlight, flood light, annunciators and related interface cards.
Center Pedestal backlight
Engine starter relays
Master Warning / Fire Warning light bulbs via the CP Flight MIP737 board and semiconductor relays.
Various interface cards.
ACARS printers
5 USB 7 port hubs
TQ DC motors

This gives you a fully functioning moving map.

You will need the following payware :
  Jeppesen FliteDeck, WideFS, Eltima Virtual Com driver.
The ini-file values you need to add are stated below the components.



Backlighting :

12 V DC LED Hi-Power LED strips and LED discs are connected to a 12V computer PSU via 6 PWM dimmer cicuits.
One dimmer each for MCP flood light, MIP Backlight and MIP Floodlight.
Separate dimmers fitted for : Overhead Flood Light, Overhead Instrument light, Overhead backlight.

LED PWM dimmers ( 0.8 Amp ) can now be found very cheap from Hong-Kong on eBay

For general backlighting such as the overhead panel, MIP and the radio bay we use HI-Power 12V "LED strips".
