progress this week

I did some testing with a sample Hall sensor  (US5881LUA) and 1/4 inch magnets. Looks like it will work out, so I went and ordered a set of 160 of them.   

 While I'm waiting for them to be delivered, I cleaned up the manuals.  I cleaned the key surfaces the first day - they were pretty filthy and felt gritty and some did not move well - but there is a limit to what can be done in situ.   This weekend since i couldn't yet work on installing the sensors, I took all the keys out and cleaned them and the beds.
Here we are midway in returning the keys to the Swell:



One of them is initialed and dated  5/17/90  I'm assuming this was someone who worked on it - there had been a reconditioning at some point in the past, felt was replaced in the manuals and pedals and in the linkage to the combination action.   There were also a couple of stops added - an 8' Tuba, and 8' Open Diapason.

 I really didn't want to do this part, but I'm so glad now it is done. When I have the sensors in and get to play it will be much more pleasant. The keys are in nice shape - there's a small chip on one, but that's it.

Improving the Manuals

Image
 I've been practicing and playing on my work in progress for several months now. That is long enough to start revealing design flaws.  Specifically, my choice to hang the magnets underneath the key-sticks with magnetic tape.  Every so often, one wiggles loose and I get a cipher and/or a dead note. I thought fixing these would be simple but as it happens, they are very hard to get to, even on the Great where the bottom is exposed - there is a big iron beam right in the way.    The Swell isn't so bad - I can swing it up and get in and correct them, but to get at the Great I have to remove both manuals completely.  After a few of these, I I started thinking about my options. The choice to do it that way was driven by the existence of a part of the electric keying mechanism which I left in place because it was necessary to the proper touch of the keys. Each key-stick has a return spring, but also pushes a lever to make the electric contacts. That lever  has its own spring. The comb

What I have so far

Image
My console has been picked up from the dealer, but won't get delivered to me till next week. That gives me time to work on the electronics.  I have a working prototype of the midi scanner for the pedalboard. My plan is to hook up the pedalboard first - partly because I expect it to be easier, the mechanism is bigger, more accessible, and there's a lot less of them.  Mostly though I would really like to have a working pedalboard to play with while I'm working out what to do about the manuals and stops. My design uses an Metro Mini from Adafruit for the controller and a pair of MCP23017 port expander chips available from your favorite supplier. The cable connects to a usb port on my mac, which is running Hairless Midi Bridge I have small array of pushbuttons standing in for pedals and it works - when I push a button, the correct note sounds in Hauptwerk, Grand Orge, Garage Band, or whatever.  Woohooo! I will upload the code to github, but right now it's in

Unit Testing is my friend

Image
I've soldered all those wires and female headers onto my SAM units.   For once in my life, I'm going to do things the right way around and test all of them before installing them into the organ. I breadboarded a simple testing widget with male connectors matching the females on the SAM unites. The power and ground wires coming from off screen above are attached to the ASTRON SS-18 I got to power all these magnets. At the bottom is a UBEC 12v-5v converter for the LED. The circuit for the reed switch is entirely separate from the wiring for the magnets, so it can connect directly to the arduino running at a lower voltage than the magnets. I'm converting here to use just one power source, and avoid having to connect and program a microcontroller for a very simple test.  As you see, there are two little push buttons.  Push the left one and the stop flips on (down) and the green LED lights. Push the right one and it flips off (up) and the light goes out. Repeat a couple of t
