Finally got to tie some pieces of scripting together, with the OpenCockpits LCD card. Initially just throwing all outputs onto a single LCD display, they will be split across multiple displays when put into the pit. Using Leo Bodnar's BUO386X to take rotary encoders and convert them to joystick button presses. Now its time to get some more panels done.

 

Some interesting learnings with the LUA scripting when getting the frequencies, it certainly isn't the world of integers! Also what was a little surprise was the minor digits on the UHF radio, instead of stepping through 0-25-50-75, the discretely roll, thing to what out for when putting I/O code together.

For those that are interested, the code is up on goggle code

The guts of the radio export looks like

table.insert(soic_conv_flightData,"8010=" .. ils_major_digit[DigitPointer])

-- Minor Digits

-- Needed to add a 1.1 as the maths sometimes rounded to .999 which causes errors in lookup

DigitPointer = (soic_conv_mp:get_argument_value(252) * 10) + 1.1

DigitPointer = tonumber(DigitPointer)

-- Lookup Table

ils_minor_digit = {"10", "15", "30", "35", "50", "55", "70", "75", "90", "95"}

Thanks for sharing

Spent some quality time with a laser building out some proof of concepts for the UFC and Radio, so much easier cutting our squares with a laser than compared to manually doing it.

[Mr_Burns]

Love it - are you glueing the button (caps) to the pcb switches below or do they have a flange to keep them in place?

 

My bloody caps, I tried to superglue them and the glue ran down into the switch choking it.

 

Did you use a laser to cut the panel face too? It is very neat.

The Caps are fitted to the switch, no flanges or glue needed :), I scored the switches from ebay (OMRON B3F-4055) and the matching caps from Digikey (SW259-ND KEYCAP 12MM SQ WHITE FITS 12MM), no superglue needed (as I'm guaranteed to glue my fingers together :)).

 

The Laser was used to cut the panel, its the only way to go.

And finally got brave and took apart the OpenCockpits CDU to install the matching buttons for the A10, it isn't laid out exactly same same as the A10, but will still do the job.

 

[Panthro]

have you got UHF working as well & what exactly would be required to drive what you have here?

 

open cockpits card + display card?

Have held off on the UHF, rumor has it the UHF LUA code may be better behaved, but until that time its the VHF radios, TACAN and ILS.

 

Currently this is running of a Opencockpits LCD card, and the Leo Bodnar card to converter the rotary encoder to Joystick clicks.

Had some time of a laser with Levinsky, used some of the great approaches used by glider to bang together electrical panel. Only slight difference was using 2 * 3mm layers of black acrylic, and the top plate is 3mm white acrylic painted with black paint, and then lasered. Real happy with back-lighting, once nice trick is cutting the 5mm holes for the leds in the back plate, this makes it real easy to install and wire up the leds.

This was in a well lit room:

 

And for those wondering, at 12V panel uses just under 80mA for backlight, there are several strings of three green leds, used a 220ohm resistor for strings with 3 leds, and 440 resistor for strings with 2 leds. Using PWM for dimming.

now that is a great looking panel!!!

[MacFevre]

Agree with DM. Very sharp looking!

[bnepethomas]

Ta guys, it's amazing what you can do with a laser and a bit of time.

You are not wrong:

 

[Panthro]

the anti-Laser

Least it is the same back in these photos.

 

the more I look at it, the more I think a laser cutter/etcher would be somthing I could use.

[cichlidfan]

You are not wrong:

 

Removes unwanted hair, and two shades of skin color, in just minutes!! :lol:

[Panthro]

Anyone have a .DWG for a hairy back??:doh::megalol:

[bnepethomas]

What can I say, emotional scared by that photo ;)

 

Here's something a little friendlier to the eyes, tinkering around with options for the center console

 

[cichlidfan]

Shouldn't that bottom panel be label NMSP?

[bnepethomas]

Yeap siree, thats one of the things I do need to touch up, as well as reducing its width, found out I'd grabbed the wrong template...doh!!!! All part of the fun of building your own bits and pieces

Cool. Looks great otherwise. Apologies for leaping onto the only flaw. :)

[Hansolo]

Looking very good. Where did you get the push buttons for the NMSP? Is it home made?

P.s. think the top panel should be CMSC :smilewink: but what the heck. I like you panels

:) typos galore, nothing like doing a science project at the last minute late on Friday night. Good to know about the errors before redoing the panel. The buttons are home made, took some green push buttons, painted them black lasered out the text, filled that in with white paint, then lasered out the symbols.

 

cheers

[bnepethomas]

Some more lasering with Levinsky, this time the lighting panel. Takes around 1.5 hours to mount and wire up the leds.

 

[Levinsky]

Pete,

 

mate!

 

that looks awesome. Well done - weekend well spent yeah? :)

Been banging away at a general purpose magnetic switch interface, using C#and OpenCockpits USB Output card.

Got a quirk to resolve where the buttons stay on, even the aircraft is powered down, wondering if anyone else has had success in interfacing magnetic switches?

 

Here's the video of them in operation.
