Re: Building a New Console for Myself

A small amount of work has been done recently. Here are some interesting things I've learned along the way that hopefully someone will find useful - they were certainly new to me.

I used my CNC machine to make the piston rails for each manual. I used 3/4" thick stock, and had it route channels for all the wiring, while leaving the bottom 3/4" thick to make it more rigid. And I used my wifes Cricut machine to make the labels, which seems to have worked out rather well.

The pistons are lighted, but I made a mistake when ordering my mddp128 from MGB. It is on its way back to him to be redone. I had him do a custom firmware that ended up being unnecessary, so he's nice enough to swap it back for me. You'll notice a couple missing from one of the manuals - as the lamps were DOA. So they have since been replaced.

This is an adapter board that I had made to convert the FFC (flat flexible cable) from my Fatars. I had made by a company called Bay Area Circuits. https://bayareacircuits.com/ . They have a nifty schematic drawing application that will convert to PCB and you can order directly through the software and they will make the board and ship it to you. No components are attached, so you have to do that part yourself.

I also learned that if you have a Fatar keyboard, if you're using the MGB hwce2x encoder, you can get either their sm-df or sm-dr cable to work properly if you use their UpSet.exe utility to actually change the Scan Matrix - it will to go either way. Each Scan Matrix is independently assignable - which is great for me, since I have 2 different configurations of Fatars at play here. At first I thought I was going to have to order all new adapter cables because my notes were all playing out of order, but Jordan informed me that this can be remedied by using that config program. And indeed, it works great now.

I am hoping to have the "table top" done within the month.

Hey this is looking great.
I would ask you about making some keycheeks for me but I'm in the UK so I imagine shipping would make that impossible! Please can I ask what make/type of thumb pistons you are using?
Thanks, James

While exploring, found an adhesive backed clear printable (either) vinyl or polypropylene material which can be laminated.

As well, printed and cut with a Cricut Explore One. Wonder how easily these labels could be removed if there was a change in plan?

Sorry, Gentlemen just now seeing this...

Yes, shipping would probably be high, but we can maybe work something out. You'd likely do better contacting someone locally.

The pistons are these:

These are easily removable. I can't speak to longevity yet, as I've not started using them but I think they will suffice for my needs. Definitely not a "permanent" option, though.

Those are pistons (from a Rodgers sell out when Rodgers was bought by the parent company of Johannes) that I have used for several organ rebuilds. Quite easy to change from the 5 volt incond lamps to LEDs which give you several options. One being to be able to use coloured LEDs on some pistons denoting function per manual/division. Never need replacing is another as well as flashing which I use to 'remind' the organist that they are using transposition for instance.

How are you taking them apart?

On the back (black connect side) near the outside edge are (180 degrees apart)) two indents. I use 2 small thin screw drivers, press each down approx 1/4" and apply a slight force toward the center of the piston. This will release the white movable button exposing the inside lamp and contacts. Be prepared to contain the white button and the spring. You'll notice the spring top/bottom orientation as far as narrow tapered end nearest toward the lamp.

The white button also has an orientation for the contact alignment. Once the button and spring have "popped out", you'll see the incandescent 5 VDC lamp. The lamp leads are fastened (glued) to the black piece. If you want to save the lamps as I did, the lamp leads can be forced (along with the lamp itself) out of the black housing by forcing the leads back into the black housing. Then using a small needle nose pliers to finish pulling back.

I actually fabricated a tool to do this.by drilling a small diameter hole (very slightly larger than the lead diameter) into a piece of (1/4") round aluminum rod. The depth of this small hole approx 1/16", just enough to push the lamp lead back into the black housing. It takes a little force to do this as the lead wires are fairly well attached to the black housing. if you don't wish to save the lamps (they are not readily available) you can of course just crush the lamp with a needle nose pliers and forcefully pull the lamp's leads out of the black housing. destroying the incond lamp.

The leads of a replacement LED can go thru the holes formerly used by the incond lamp.With the MGR2/LITSW boards from MIDI Hardware, both the switch common and the lamp common are negative. So there is one negative common, one switch lead, and one lamp lead, 3 connections per piston.

I used 3mm either clear white or (for some pistons) colored LEDs.

A further advantage of using LEDs, to me, the 'look' to be more modern. You can add a LED dimmer circuit to control the brightness either with other LED (music rack, under the keydesk) lighting or separately. All this is is a little extra work, but in my case, thought it worthwhile. As is sometimes said - 'hope that helps.'

BTW, mother nature just did a dump of that white stuff that will need to be shoveled. :roll:

I found if you decide (commit) to do this re-do LED procedure, it's best to do all pistons in a production style method. In other words, do one step at a time to all of them. Have a separate container for the white buttons, a separate container for the springs, etc. A helpful "tool" is a small vise that has a horizontal "centering" groove that can grip the (inverted) piston's flange. The option is to have three hands., i.e. one hand to hold the piston and one hand for each screw driver to release the white button. The process may seem long and involved, but it's not too difficult once you get "the hang" of it. Actually, it became repetitively boring. :wink: Good chance to listen to some music such as

https://www.classicalradio.com/#default or

https://www.organlive.com/

I'm guessing that course I took (a long time ago) in Methods Engineering can be useful at times. 8)
