I am getting close to the point where I will have to stop procrastinating and actually build my TQ… More parts arrived today from AliExpress, my favorite online shop, consisting of Buck-Boost modules, pulleys, drive belts and some nice big bearings.
My TQ ‘concept’ is to make an automated quadrant without using complex software like ProSim to handle the automation. I have a plan, mostly in my head but some of it is now on paper, which will allow me to drive my autothrottles using off-the-shelf components, and some clever programming. I still need to design the clutches for the A/T drives, and a simple way of attaching pots to each axis, but I think I’m on the right track.
With this latest arrival I am getting dangerously close to the point where I am going to have to start assembling this thing. I have loads of good ‘seconds’ from work which I will be re-engineering to fit with my new design, then all that is left to source is the drive motors… I hope.
At work we recently started to convert our first simulator, our own ‘Ground Zero’, into a display piece. A positive (for me) spin-off from this is that many parts not required for the display project have made their way into my 737 project. The two ‘prize’ items from the haul were the pilots seat, built by Russell from an old 737 passenger seat, and the Rudder Pedals, which I made in my former life and sent South for Russell to install in his sim.
The Seat has had a bit of an upgrade, gaining seat cushions, armrest covers and headrest from real 737 seats. Next it will get a height increase to bring it up to my preferred seat height, and a repaint in Boeing grey..
The rudder pedals will have a big re-condition, with new linkages, and of course a paint. It will be a nice feeling to have the pedals I built all those years ago, in my own sim!
I also scored one of the yoke heads, which again I helped make back in 2001 or so, I’m not going to use the yoke in my sim but I plan on making a display piece out of it…
I have been using up recycled interconnect boards from the skip at work, but as that source is quickly running out I thought I should find an available substitute. I like the idea of using CAT5 cable and connectors for running between my components and IO boards, so I looked for an RJ45 connector which would suit my needs. A quick search on Aliexpress.com came up with these:
For around $3 each, these things allow me to wire 7 IO lines, plus a common to each cable, which in turn runs to my centralised IO.
My first use of these will be on the 737 MIP, when I wire up the remaining buttons, then the long-awaited EFIS Panel, where I hope to design the connector into the panel, as an integral part, allowing for easy removal for maintenance.
After a bit of a revelation it occurred to me that for a very long time I have been trying to create a simulation environment in my sims which is almost exactly the same as DCS:World provides. I have been, for a long time, been trying to develop a multi-platform ‘combat’ simulation, using the tools with which I am very familiar. I found it very interesting that I opted to stay with my known and familiar environment, rather than taking a leap…. In this case I was very ingrained in the development of FS9 content, I was comfortable working in the environment, I could ‘talk’ to the simulation, I understood the way most things worked inside the sim. What I was really after was a complete combat simulation covering air land and sea warfare, with a Tactical Commander function. DCS:World has always been on my radar, I have ‘played’ around with it over the years, but never anything more than that. Recently though, with my interest in VR, I have been learning more and more about how DCS works, and how I can develop content for it, and make it into the sim I’ve always been looking for!
So. I am now ‘officially’ (as officially as I do…) I have stopped development of TACOPS and pretty much all of my projects around trying to morph FS9 into a combat sim….. My focus now is on development of content for DCS, focusing on NZ and the Cold War era. My 737 and Arrow sims will continue, running FS9 and FSX respectively, but wont be trying to be involved in any ‘combat’ mission.
It is very odd to look back and contemplate all the time and effort I have spent on a project which was merely trying to replicate something which was already around..
So now it’s onward and upward… I can concentrate on using the best software for each of my sims, rather than trying to make the one platform do everything I wanted.
SO, New software plan – TA-4k Skyhawk will be running DCS:World. – Piper Arrow will be running FS9 and/or FSX – Boeing 737 will remain on FS9
Over the past years I have been slowly collecting all of the used, cast-off or reject TQ parts from work… Today I thought I’d gather them all together and sort out what I had.
The list of ‘missing’ parts was not as long as I had expected, which was a nice surprise. There were even a pair of ‘Classic-correct’ trim wheels (from a development project at work..) in the box! My TQ build is going to be a long slow process as I get the time to work on it, but at least I have a good bunch of the parts 🙂
I had planned on having the overhead as just a static panel, with not much on it, then I evolved it into having only the switches I needed, maybe a ‘fictional’ panel covering the function I needed…. Well, that all changed when I scored a pile of old, quite used FDS panel faceplates from an NG overhead, most of which are usable on a classic. Despite only needing a few switches for my needs, I plan on fitting all the switches and annunciators….
I will need to draw up a series of backplates, and fit dzus fasteners. Then finally I’ll have to either source or replicate the missing panels. **Eagle eyed spotters will notice that the Cabin Temp panel is sitting upside-down!
Some time ago after an in-depth discussion with an avionics guru, I started to figure out how I would interface my 737 ‘Gables’ radios, by using their OEM connectors. Understanding the pinout, interpreting the “ARINC 410: 2 of 5 code” and converting it to a valid frequency.
While I was on holiday I spent a bit of time and buzzed out all the required signal wires and connected them to a Leo Bodnar BBI32, to see if I could get valid data off the device. The good news was that I could see data pins changing, the bad news was that without a +5V signal I was not getting reliable data. Next step is to get the +5V working, and see if I can get some stable data out!
I’ve had the gear lever in the 737 panel for a while, but haven’t gotten around to wiring up till tonight. Part of the reason for taking so long was that the lever “ground lock” meant having to pull the override trigger every time you wanted to raise the gear; not very satisfactory. Today at work the guys pulling a cockpit apart discovered that removing the solenoid on the lever mechanism was really easy, and made the lever move freely up and down… so tonight I removed the front panel, striped out the solenoid, and secured the actuator so that it wont inadvertently move and lock the mechanism. Next, I grabbed a spare gear lever (yes it IS a disease!) and pinned out the micro-switch on the back of the lever mechanism and figured out a strategy for interfacing it.
As an easy connection between aircraft components and my IO interface I am using some old RJ45 to Screw Terminal break-out boards made by Ruscool over 10 years ago, which I am recycling from our prototype 737 at work. The gear lever switch is connected to the screw terminals on the board, then a CAT5 cable runs from the RJ45 socket of the board to a Leo Bodnar BBI32 USB Input Controller.
All 8 wires of the CAT5 cable are utilised, giving me 7 inputs and a common from each cable. The BBI32 is a great board for momentary, on/off, rotary switches and even rotary encoders. I’ve used a bunch of these over the years, both in my own projects and at work.. I absolutely love them! This sim build will be using at least 2 of these, probably more… depending on how well my OEM Radio interfacing goes!
So far I’ve used 1 of the 32 inputs, next up I hope to interface the auto-brake panel, then move across the MIP wiring up everything, even if I don’t have a use for it at the moment… much easier to wire it now than try and add more in later!
As I mentioned earlier; we are stripping another 737 Classic cockpit at work, so I got a couple of new bits to fill in some more gaps, and even started filling the overhead 🙂
As well as the Flight Deck Door panel, there is a “Terrain” control panel, which will go between the CDU’s, and the Cabin Temp panel for the overhead. With any sort of luck there could be some nice overhead panels coming in the next shipment…. watch this space!
Today I had the opportunity for a very quick visit to a Level-D certified 737-400 simulator. This sim is getting old, but is maintained in an immaculate condition, but sadly will be decommissioned soon as the airline who owns it is moving to NG’s The best part of the visit was that I was able to get good photographs of the next couple of items on my ‘build’ list for my 737 Simulator.
During a recent visit to the Air Force Museum at Wigram, Nathan and I looked at the ‘mock’ C-130 they have as an interactive display, and talked about things which would be cool to incorporate into the upstairs part of the ManCave.
The interior of the C-130 was pretty simple, grey vinyl material, with suitable stencils and very basic window frames made for a really cool effect. This may be the theme for the area at the top of the stairs where the 737 passenger seat is located. The plan for the seat was to have a window with a side-view from the 737 sim…. maybe an austere ‘military’ interior will fit in well…
While we were wandering around the museum we had a wee look at the Mosquito sim. Despite it being quite simple, it looks impressive, and works well… more motivation to switch the Skyhawk to a combat sim…
