Throttle Bay Progress

This weekend I was able to get the final bits of wiring done on the Throttle Bay and began programming all the inputs.  As of last night I was able to get everything setup in FSUIPC in P3D V4 except for the FMC keys.  I’ll need to use opencockpits SIOC for that, so that’ll be this weeks project.

Of course it wasn’t until I was programming the toggle switches I noticed I have the “off” and “on” labels for the logo and collision lights reversed.  Whoops.

I was hoping to make some progress on the MIP wiring but I ended up running out of wire, so that’s on hold till my reorder of wire arrives this week.

So in the mean time I started working on a overhead panel project.  For this panel I was thinking rather than having all the text and such etched on the panel directly, I’d create a printed overlay with it all along with some colored panels.  This way the panel could just be made with the cutouts for indicators and switches, cutting it’s cost by 50%.  It’s an early look at the photoshop file for the overlay.

Throttle (almost) Done

Winter time has kept working in the garage to a minimum but we’ve been having some warmer weeks lately, letting me get some work on the cockpit hardware done.

I’ve managed to nearly finish the CDU Bay/Throttle Pedestal. Only thing left if a couple wires that will need to be connected to the PCB board once it arrives.

With that pretty much done, I’ll focus on getting my MIP display frames 3d printed from Shapeway and begin the MIP wiring. Since I made the unit rather short on depth, figuring out a decent layout for the hardware should be fun. Here’s it’s current state:

’til next time. 🙂

The Winter Season

With winter weather in full swing now, the cold garage has been been slowing me down from wanting get in there and working on the 737 panels.  Since November I did mange to some progress, but not as much as I would’ve liked.  Here’s a recent photos of the panels, along with a new workbench I managed to build just before the temps dropped in later December.

Panels Arrived

My two custom fabricated panels arrived yesterday afternoon and they came out great.

Panel Panel

My two main concerns were the opening for the FMC and the AFDS panel, but luckily they came out perfect and the items fit right in. I ordered these from Front Panel Express this time around. Order to delivery took 12 days and the panels came extremely well packaged as well.

With the panels in hand, I can now work on building up the MIP frame and a housing for what I’ll just call the CDU panel.

Throttle Stand

Not many construction photos of this as I practically was planning it as a built it, but here’s a throttle stand I built for the JetMax throttle and my “CDU Bay”.  While I have the stand from JetMax for the throttle, I needed something a little shorter so I could slide the whole throttle unit under the table when not in use.

August Updates

Been a while since my last update, I’ll try and recap everything that’s been on.

FMC

I left with the ordering of a custom PCB board for my OpenCockpits FMC Kit.  They board arrived in a couple days and looked great…. at first.

At first I noticed I goofed on the pin spacing for the resistors, then I next noticed I had the pin spacing wrong on the header pins for the LEDs and backlight inputs. I though no problem, I cna work with that still. So i went and soldered all the SMDS and switches in place. And that’s when I when I found the big error. I completely missed including some switches into the traces. So many of the switches didn’t. Doh!

So it was back to the drawing board. I updated the design to move all the resistors to the back of the board in a single spot, redid the wire diagram for all the switches and also redid the diagram for the backlight to make sure they were correct too. And fixed the header pin spacing. The 2nd boards came in and this time, everything worked. 🙂

So with the PCB project now complete, the assembly of the FMC is slowly underway.

 

737 throttle

My original plan for a throttle was still up in the air. With Jetmax no longer selling their throttle unit, I was looking into building a housing to use a Saitek throttle in.  And the 1 day my phone dinged. It was for a Jetmax 737 Throttle that showed up on Ebay.  After a quick look over the pictures, everything seemed to be in good condition so I jumped on it.  A few days later, I had my throttle problem solved.

I plan on building a small CDU bay to go in front to probably hold a few custom panels with some buttons and switches on it.

Other Stuff

I’ve pretty got my MIP layout finalized.  I’ll have to put together mock up but basic plan is to put the FMC on the left side, 3 displays and then MIP switches like landing gear, flaps guage, etc..  The top portion of the panel with have the MCP unit, sixpack indicators, master/fire switches and the COMM and NAV radio panels.  this way I keep the bulk of the wiring and I/O cards contained into a single unit.

Speaking of MPC, I recently picked up a OpenCockpits MCP from them last week.  I’m trying to get most of the panels I need in order to finalize where cutouts need to be in the MIP panel as I plan on getting a metal frame fabricated for it.

Ended up with the Honeywell version as that’s all they seem to sell now, but I do like the custom knobs on and was delighted to find the unit comes with backlighting installed already.  I haven’t tested that out yet though.

I’m also working on some PCB’s for my Comm and Nav panels for the 7-segment displays, so I’ll show those off whenever I get them done and fabricated.

That’s about it for now.

Display Panel PCB Success

Today all of the PCB’s I made for my 7-segment displays arrived. I was eager to see how they worked so off to work I went.

Here’s the PC Boards. 1 card to attach to the Opencockpits DisplayCard, 1 for the Nav panel, 1 for the Comm panel, and 1 little jumper for the ATC panel.

 

Interface board attached to the DisplayCard.

 

Interface board attached to the back of the NAV radio panel. The displays are soldered to the board and then a 40-pin IDC ribbon cable connects the displays to the DisplayCard.

 

And when I fired up all the digits….


Success!

This will make wiring up the displays soooo much easier.
