Airbus gauges for the MIP
Hello Builders,
is there any place, where you can buy the two gauges, needed for the main instrument panel of an airbus A320? I talk about the clock and the brake pressure indicator. I know that the clock can be displayed via PM, but I thought about a full hardware solution via USB without any other hard- or software dependence (except for a self written interface).
I don't know a supplier for these gauges and the only reference for this parts I found were for the clock:

And for the pressure indicator:

I liked the idea with three small servos and therefore started to plan it, here is my intermediate model of it:

If you like the faceplate, you can download a 1MP version of it from http://www-public.tu-bs.de:8080/~y00.../faceplate.png or I can provide you a svg, if you like.
My question: Has any of you already built the gauge like this and has any advise? I currently have no good solution for fixing the needles on the servos except glueing, because I don't know how to get the gear wheel as a geometry in a needle. The interface can easily be done via a microcontroller, or with given solutions that are available on the market right now.
Well the other have of my project is the digital style clock, with at least the most important functions, first the pictures of it:

Here also the question, I have seen that some of you use a monitor version of the clock, but I found no supplier or builder and the guy from the link in the introduction has not yet finished this clock. Is anyone out there, that already built this clock? I have big problems to find the correct display type, the 4 digit clock types are only available in green, yellow or white ones are produced, but it seems no distributor sells them to private customers.
Well I hope I get some replies on this and maybe you have solutions for any of my problems or at least some tips. If you want to get any more informations (preleminary circuit diagram or PCB-circuit layout of the clock or dimensions, drawings, etc. from any of the projects), just let me know.

Progress with the brakepressure indicator
Even though, nobody replied on the initial topic, I hope I am not boring you with the progress of the gauges. I am doing the brakepressure indicator first.
I etched the PCB last week, soldered it yesterday and after some tests yesterday evening, resolderd it today. The result with one servo attached looks like this:

In the afternoon I tested the device, on the first hand there was a problem in my self written software, then with the external oscillator, but I managed to get it work and now the software reads out the values of left/right brake applied from FS, converts it to a servo position and sends it via USB to my PCB, which drives the servo, which looks like you can see in this short video (some braking applied with my pedals, therefore the movement is not very smooth):

I hope you like it and I inform you after building the rest around it, if you like. If you have any questions, feel free to ask.
