Die drehschalter die man im diesen tutorial seht gibt es bij Reichelt fur € 1,80. Und man braucht das PCB nicht weil die Drehschalter aus dem Tutorial Lotaugen haben. Eine Drehbank ist nicht nötig. Ich habe es nach gemacht mit ein Bohrstandard (richtige wort?, ich meine so eine senkrecht aufgestellte Bohrmachine) und das ging sehr gut.

@all

Ich verstehe immer noch nicht wie man der untere Knöpf mit einSpannzangen befestigen kan. Gibt es da dan noch raum fur die 4 mm axe durch zu lassen?

Wen jemand ein detail foto hätte würde ich das gerne sehen.

Yes, but the ones dirk used are also smaller in size - the cheap 12-step rotaries are rather big - this is a good alternative to keep in mind anyway - both methods to do a concentric switch work probably just as well.

The axel goes through the "outer" switch shaft center and the small knob is tightened on the tip that pokes through the larger axel.

The large knob has a hole through. Those "clamp" knobs have a small nut that you tighten that just "clamps" the knob around the axel - and the small axel goes through the big axel and the entire knob. It could be that my german is so rusty that I just didnt understand your question though. :D

Hope this helps!

Thanks Tuomas for the picture. It is very clear now.
Only have to start searching for these things.

So if anyone knows were to find these?

Could these 12 stage rotary's be used for the comm radio?
 

Hi there,

The modified knobs look great, but

Could these 12 stage rotary's be used for changing the freq of the comm radio?

Kind Regards Jan.

@ Jan


Yes ofcourse. They are ideal for caom ,nav, adf.

Nor so ideal for heading, course. Because if you need to turn 270 degrees over right you would have to turn the knob 270/12=23 times.

To change the transponder is only from 0 to 7, or com from 118 to 136, nav from 111 to 118. So that is only 0,75 to 1,5 turn of the knob.

How to connect
 

Thanks Norbert,

Oke, that's good news.:D
How must I connect these 12 stage switches to the key pcb :confused:

For example to change the comm 1 freq.

Kind regards Jan

Best would be a 3 x 4, that is less soldering.

It is described in the fsbus docs how you connect these type of switches.

Thanks Norbert I'll go at work with it.;)

Hi Norbert,

you may try the 12 stage for heading, because the router software has acceleration. The faster you turn, the more steps are added. The parameters when acceleration begins and the increasing factor is user tunable for each switch.

Welcher der Regeler (innerer oder äußerer) stellt bei der 737 Dezimalen ein und welcher die Ganzen? http://dany1.pisem.net/nixweiss.gif
