Hello,

A quick question:

Can you wire encoders direct to the Open Cockpits master card, or do you need an additional board to do this?

Thanks,.

You can wire "grey" type encoders directly, other types must connect to another card, the encoders card. The grey type I use are the CTS like OC sells, Digikey has them too, much faster delivery. They are not concentric but do have a pushbutton built in. I use them on my glare section. I think this is the one I use, but I will check later when I get home..

BTW, if you see the 10-pack of encoders with knobs on ebay, be cautious.... this is a great price, and in some situations the smaller form factor is needed. These encoders work, but they are very noisy. They bounce like crazy compared to the CTS encoders. They behave pretty well with Leo's card and the OC card... just be prepared for a little over/undershoot sometimes when tuning.

In my experience of wiring encoders to Leo's cards is that the rotation is very slow and that you have to create a lot of revolutions to access the required position, hence why having alook at OC's cards now.

Thanks for the heads up!

Cheers!

If that's an issue, see my threads regarding the MJoy16, this card has a unique feature regarding fast and slow rotation on encoders.

I have known about the MJOY16 for some years, but I have no tools to make one, I have a soldering iron, other than that I would not be able to make a pcb or anything, nevermind drilling the tiny holes etc, this is way above my league....

It IS the leo bodnar at the moment that's in my pit, thinking of going over to the OC stuff, I have an OC servo card which is good, just not ventured into their I/O cars as yet.

Alex I am just about to have PCBs made for them and the Igor Plug, I will keep you posted on that. The OC mastercard is pretty responsive, but again tuning whole units by stepping thru decimal units or thousands of feet 1 hundred at a time is slow. Maybe a request to Leo to make the response rate adjustable?

BTW, could you email me readable copies of the throttle drawings you posted? I can't quite read the dimensions on the ones you posted.

Here you can find some info about the encoders with OC and SIOC.

Good info here.
Does anybody have any suggestions for low profile encoders that work with the OC MC? I have the encoder that OC sells but they are rather bulky for a MIP I think.

I have purchased these encoders on ebay and they are small. They are a bit noisy but usable. I have tested on Leo's card, they work fine. Sure can't argue with ther price.

Yeah, I have seen them, Sure electronics offer a similar encoder with silver encoder knobs for the same price.

A good deal here, the noise of cockpit will overide the 'clicks' you hear, so not a probably.

These encoders are used by many people on here and work well with all sorts of I/O cards.

Thanks.

Yeah, I was saying earlier that they are noisy in an electronic respect. If you look at the signal they generate on a scope they have a ton of bounce and bounce-back. HUGE amounts more than the CTS encoders. Software on some I/O cards de-bounce the contacts and make the signal plenty usable. I put together a standalone FCU a while back with a AVR and a little flourescent display and used these.. I just accounted for the excessive bounce in the code and they worked fine. Actuall a cool little project.

As far as these encoders go, if you like the sytle of the knobs the price would be decent just for the knobs themselves. On the ones I got the top pops off and you tighten a hex nut to secure the knob to the control shaft.

Hello

You could try one of these: (inside the blue circle)

A shot of my 767 MIP.

One problem - you'll need Encoder-II converter as long as you want to run OC-hardware.
These small mechnical encoders are very often used in PC-mice and are 1/2 cycle.
