While waiting for some motor parts, i am starting to setup a "final solution" with a adafruit pcb. Really great board. I will solder some connections right to it, but i got to test the screw-connectors and they work great.

A/t disc -both sides complete
Toga both sides complete
Fuel cutoff idle -both complete.

Still to hookup the trim switches and fuel cutoff "off mode".
Add the parkingbrake test switch and i think all switches are done.

Hope you didnt solder that Teensy in directly?  Always use a socket.

Actually i did solder the pins. Is that a bad idea? This will be a permanent solution. Now that i think of it, it would be a problem though if the teensy brake. The replacement will almost be impossible...

Exactly, trust me, i learned the hard way.  Stuff happens and they don't like voltage higher than 5v or they go poof!   Need to keep them easily replaceable

This will be my drive for the throttles.
Lots have changed to string pots, but for the price, i want at least try this solution.

The gear thats driving the chain is still missing

While waiting for parts i am continuing on my mcp backlighting. Not fun at all and superhard to get even lightning in the simworld panel.

Really great thread to follow. Thanks for loads of practical advise.

Would it be more practical to push wires into the Adafruit board from below, solder from above and then trim any excess? This might help wire distribution, access and air distribution. Easier to get to the teensy as well.

Cheap String pots that we use, work great

Cool, i wonder if anyone had tried these ones.

Then i will use them for my speedbrake and Flaps to begin with. (if not my setup works like a charm =))

How many turns is the pot that are using in the pic you posted?  It looks like a standard pot?

1 turn only, its a panel pot. If i cant use it due to gearing or too large movement i will switch it for a normal pot and calculate the movement and position in the software. The sim will always boot up with throttles at idle.

I knew it!
Replacing the red segment displays to white like the real boeing made a great improvement.

The backlighting is a P A I N!

Dont think i will improve it if its not good, its just tooo tight of space in the mcp!

Theottle progress!
Left lever is moving.

Right now with my gearing and 9v battery it takes about 6sec from idle to full power. Hope to get extra speed with the 12v power supply.

My main problem now is the wires. I need one with a steel ball that locks into the levers. Right now i tied a knot, but i dont think its working that good.

Kurt, when I did mine I used a cable ferrule from Home Depot(see attached picture..you would just use the single barrel one).   You just smash onto the cable with a hammer.  You can then tap on it to shape it more ball like and will do the trick.  Make sure to safety wire it in place like the original ball was so it doesnt pop out of the slot..

You can get the correct balls for the cable from Aircraft Spruce 
http://www.aircraftspruce.com/catalog/appages/sa110.php

You would need the SA110-3 as the bore in the thrust lever cable wheel is 1/4"

This will need to be swaged onto the cable (or you can smash it with a hammer, as Scott suggested :)   I tried with a hammer, but  these balls are quite solid and i couldn't get it to grip properly.

Any marine/boat repair place should be able to swage the ball onto the cable for you if you mark where it has to go.

That being said, there's obviously lots of ways to do it, I initially used cable stops like these:



I was worried they could come loose though, and that would mean a whole lot of disassembly and tightening, so I went for the solid option.


I guess a $1 ball getting shipped to Europe is another thing to consider, but you could be able to find them locally.  I got mine from Aircraft spruce as I ended up ordering a complete new set of screws/nuts/bolts etc to re-assemble my TQ as a lot of the heads were starting to round off and I wanted it to look as new as possible after the time & money invested :)

I know I can't add to this post and have already asked if there were any MCP builders out there...but just wanted to say by reading your posts here on theB737 MCP I'm learning more about building your own MCP...so thanks
