As promised here are some pics.
In the first picture you can see the organ has the touch screen on top with a customized screen saver.
The computer that gos with the monitor will be just for this organ.
So it will be custimized with organ software just for this organ.
Later on the computer will be mounted inside of the organ and the keyboard and mouse will go wireless.
So all that will let you know it is a virtual organ from the outside will be the touch screen.
The organ legs and pedal board is missing(I have them, they are just behind the organ).
I also need to do some cabinet work with veneering since the organ was damaged in the move.
But I am a handyman too, so that will be done right too.
First things first though.
The touch screen was a steal on ebay for only $40!
The monitors are missing the stands, vga cable, power cable, usb cable, and the bezel isn't complete.
I got a cheap stand for $50, and the cables for about $30.
So a total of about $150 for a complete setup with a custimzed bezel(I will use wood molding to match the organ).
But this is a high quality touch screen with a glass front.
At half the cost of complete 15 inch touch screens.
I can provide details on ordering one if you guys want one too.
The computer is a refurbashed E-Machines 3ghz,
dual core with 2gb memory(expandable to 8gb),
160gb hard drive, DVD writer and Vista preinstalled from Tiger Direct.
So it should have the horse power to to run the virtual organ software, etc.
This whole computer with keyboard mouse and 10w powered speakers(temporarily setting inside of organ,
to be replaced later with a 100w amps or a receiver to power the real organ speakers) was only $200!
Midibox electronics $300.
3 new keys $30.
122 push button switches $120
Various hardware about $100
All in all I have spent around $800.
But this is most of what I need except the amps.
Those I hope I can build or buy a cheap 100w receiver for under $200.
Plus my organ repair guy said he may have some amps I could use(I may also see if I can use the old amp)
I figure another $200 should about wrap it up.
So in the end my budget will be around $1000(with some work involved)
I will also use the leslie speaker for the sound it produces.
Just need to figure out how to work it into the midi electronics
for switch detection, and channeling the appropiate sounds to the leslie channel.
The rest of the stop contacts for the leslie will work the origional Baldwin motor circuits that turn the lesley.
The second picture is of the old contact boards and old keyboard electronics.
The third and forth pictures show how I made the new push button boards.
These new boards only have one octive of switches installed right now.
Plus I will need to solder wires onto the switches and add terminals.
So they aren't complete yet.
The midi dins and cores will mount to these boards too.
I had to test it out to make sure it worked before buying 122 switches.
The board is full adjustable for height by washers.
The boards don't destroy any of the orgional integrety of the organ.
No new holes were drilled into the origional organ.
I just used the old mounting holes from old contact boards.
The push buttons have a bit more firmness than if I used smaller micro switches or touch switches,
but so little from the origional feel of the organ keys(the old contact board also had springs so it had a bit of firmness too),
that it was worth the higher quality of push buttons.
Plus with micro or touch switches I would have to be more exact on the height, etc.,
since they would have a minute distance to activate the switches.
They eventually would get out of aligment, etc., and require constant fixing.
I initially bought a couple of cheap portable keyboards electronics from a local organ repair guy,
and was going to use those contacts.
But they had resistance, and I wanted no resistance.
Plus those contacts were so cheap that they wouldn't last the long hall.
No wonder he is always fixing those keyboards!
When I am done with my switches they not only will be wired to terminals
to ease my hooking up the dins, but they will easily be individually replaceable.
So later on, if a switch may fail, an organ repair person can easily replace them individually.
I am also documenting the new electronics and will make full schematics
of the organ electronics, and detailed info on the computer and software,
along with a repair manual to replace and align new switches etc(everything will be adjustable for exact alignment).
Don't forget:
This organ will be passed down to my son and if he needs it to be repaired later by someone else,
it can be.
As you can see these boards look like shelfs!
Well they are!
I initially used 1/4 inch hard baord and manually cut them.
But I needed to go up to 5/8 inch since 1/4 inch was too flexible.
I am using hand tools so my accuracy isn't exact.
So I found these 36 inch x 8 inch shelves at Menards, and they were exactly the sizes I wanted!
For $4 each it was worth it, and while I was at it I got woodgraned laminite, plus it saved me some cutting.
You won't see them from outside of the organ, but it was a free added touch.
The metal strip that the switches mount into is 1 inch aluminum that I had laying around.
Those holes were also hand drilled but they are accurate enough.
The metal on the back of the keys, where the hammers strike the push button switches,
can be bent to align them perfectly with the buttons(soft metal so need to be careful not to stress it out though).
The height of the boards can be adjusted with washers.
The distance from front to back can be adjusted with moving the outside mounting screws(Baldwin designed this part in,
the holes allow front to back movement of 1/2 inch , so I am just taking advantage of what they already took into account).
I also had to replace 3 keys that were damaged.
The newer keys are whiter.
Anyone know how to whiten up my old keys?
I tried Acetone but it didn't work.
I am a heavy smoker so it could be from that,
or they are yellowed with age.
They are plastic.
If you have any questions, comments, suggestions, advice,
or want more detailed pictures of anything, feel free to add to this thread.
I may be asking for help on various things as I proceed too.
