Hi Peter,

Sent you a PM.

For others who would like one printed, I cannot sell it for a profit since Joe designed this. However, if you pay for a spool of filament to cover my time printing it and the machine time of 10.5 hrs (includes wear and tear, plus electricity), I would make you one.

Also, if Joe decides to print them for others at a profit, I would not object, nor print his design.

And, you guys know Karen and me, we are a very honest couple...always  ;D

If you’re interested, please PM me.

John

Master caution recall switches.

These are OEM but not the correct one. I will have to change the labels and also implement a microswitch when pushed.

It id a CL panel without the analog gauges.

I might buy a replica panel and fit the hardware in the NG panel. Dont know yet.

It says White Dome Light and it is coming from my Aft overhead panel. It shines down on the Throttle.

are you going to use the  master dimmer box ? yout overhead chart lights  flood lights storm lights side panel piller liggts  etc all work from this box ..in short lighting is a huge deal and most are just happy that the bulbs glow ..

I am gona use mosfets and control all lighting from the software/flightmodel.

So when you flip the gen busses the light will flicker etc.

You could also use a relay that switches when you select a different source.

Thats a good idea and its what i would like to do.
I just hope that there is no condition where the backlights is reduced by lets say 50%. In that case i have to hook it up to my microcontroller.

Wouldn't a relay be more problematic, especially with the EMI?

There are some really high power MOSFETs out there, and I assume the circuitry would generally be simpler.

You do realize that the actual airplane uses relays for almost everything?

Jeffrey

Edit,

I don't think using a high power mosfet is wrong, however my intention is using relays as per the real aircraft. EMI is always an issue and needs to be dealt with where necessary.

Yes that's of course true, but this a sim, including hardware that isn't designed for electrically noisy environments.

Anti ice panel interfacing!
Love the db9 connectors. This way i modularize the hardware from my teensy circuit. If i make a crappy one or it brakes, i can easily replace it!

Hahah nice Bernard!
Everytime i think i am overwhelmed with wires i look at some pictures from your cockpit! hahah

Your build is a whole other level and is extremely cool to replicate the hardware aswell!

My build is the opposit, shortcuts everywhere. =)

I connected the backligth to one channel on the ULN2803a.
The max current per channel is 500ma.

Anyone know the ampdraw of a OEM backlight bulb?

The chip dont even get warm so i guess i am safe. Tried measure it with my voltmeter but failed, dont understand how i should connect it properly in this circuit.

Kurt,
To check current draw of bulb, just put your meter on dc Current(MA) and  put the meter
 in series with the bulb. That simple.

My voltmeter only has 200ma as setting with DC. I figure my circuit will put out around at least 400ma?

Is it okey to use 200ma setting?

It's best not to guess in these situations but be sure!

As far as I know lightplates can be removed and on the back side you'll find the part-number of the lamps used on the plate.

You may find MS90451-6832 which is frequently used.

Searching on the webs shows a current of 115mA per lamp.

Yeah, i am 100% sure of what i am doing, just that my max reading is 200ma. So measuring all bulbs toghether just gives me 1. =)
So measuring each plate gives me this:

144ma
107ma
139ma
101ma

HAhahha Its 491ma all togehter and 500ma is max / channel on the ULN2803a so its safe for my chip!
Funny thing is that one bulb is out in one plate, so it will incread after change! =) Murphys law! one bulb is about 60ma!

I will have to paralelle two channel, that way i can draw 1 amp with no problem! =)
