MiG-21 panel idea

[WildBillKelsoe]

I have this in mind but wonder how to connect this quantity to a single microcontroller.

 

Also I wanted to know how many positions are there for ingame weapons selector so I choose a proper switcher.

 

For the bottom half I might add trim wheels made of rotary encoders.

 

Mostly momentary types pushbuttons, rocker switches, 12 or 13 (depending on feedback) position rotary switch, and toggle switches of the DPDT/DP3T variety.

 

 

Chime in fellas and please advise on the most appropriate microcontroller as I am trying to figure how all this would fit into one unless I use that term where 2 or more controllers are connected together.

 

 

 

 

--Update--

 

 

 

I have read some more about this board and it turns out that I either need to get a separate switch board from DTA or to use the bodnar A for purely trim and axes settings. I decided to go with the latter.

 

For this, I'll be using the A bodnar, 8 total analog inputs consisting of 5 axes potentiometers for

*MFD range,

*radar range,

*radar vertical,

*target base,

and *radar horizontal;

 

Exclusively for FC3 27/15

 

and 3 rotary encoders for trimming P-51.

 

The left half will be the trim encoders sending pulses to the keyboard and will be 1:1 so that fine tuning is better without taking all day for trimming. 2 bit. The right half will be the FC3 axes.

 

Here is a rough outline inside a 15x15 cm project box with 5.1 cm water bottle caps as knobs.

 

The rotary encoders will be on the left and sized 18x27 mm and the axes pots on the right and sized 13x13 mm with 24 mm knobs fitting the 6.35 mm (1/4 inch) bushing of this variety. I yet to find somebody to CNC the trim knobs otherwise I may need to drill the water bottle caps and let them run through the encoder shaft or use the bodnar knobs.

With exception of some Desktop Aviator controllers, the most used controllers support up to 32 buttons (can be encoder in some) and 8 axis.

 

Some controllers support up to 128 buttons.

 

For Mig-21BIS weapon selector a encoder will be good since is need only one button pressed (next weapon) if turned right, other if turned left (previous weapon).

I assume 12 bit incremental type rotary encoders. The problem is also encoder knobs very difficult to visualise without buying them. I dont want same size for all encoders but rather trim ones should be bigger for fine tuning by grip not fingers only.

 

Yes I know its desktop aviators to get the 2095 maybe?

A encoder - like a pontentiometer - can use various knob types, just pay attention if the knob axis has slot for bolt or for is knurled pressure knob.

 

This Desktop Aviator 2095A is for the case that you want use various encoder, for just one you find more affordable and flexible options, eg. Bu0836A, will support encoder, button, axes - can use for potentiometer for adjust gunsight illumination, in that weapon control panel.

 

A good "Mig'ish" look knobs.

But on its product page it says it uses the Bodnar BU0836 chip.

I will use this as selector

 

 

But I yet to see the one with adjustable stops.

 

So I'm assuming it will be SP11T but I'm worried that the 11th throw will be OFF so one of the selectors will not be working.

 

I guess 5V and -500mA will be the key in selecting the encoders. I'll look for geared ones (like car audio) to obtain more precise trimming.

 

For wire, I'll use 24 AWG assorted color 15 feet spools or get TDA 2/3 pin connectors to solder to the terminals on encoders and such and plug in to either Bodnars or TDA. For the IR/N/SARH SP3T emulator as a shield?
