My own personal Research Folder with Notes on AGO standard pedalboard, standard bench height, height of keyboards to pedalboard, readings on MIDI wiring, diagrams and schematics:

Sketch of where the organ is going in my room, with precise measurements! Taken with a tape measurer and everything!

I have a whole bunch of sites bookmarked, including:
–Allen ‘Princess’ Pedalboard MIDI Conversion: a kind of walk through for MIDI encoding a pedalboard with contact blocks
–Hauptwerk Forum
–OPUS-TWO Instrument Control System
–Artisan Organs: midi circuit boards & serial input boards
–Classic MIDI Works
–Mr. Randall Mullin’s Hauptwerk “walkthrough”
–AGO Standard Console Specs
–Midi Boutique: another MIDI system
–DTS MIDI system: Midi encoders, controller cards, decoders etc (Ended up getting their PIC-1 Pedal and Swell Shoe Midi Encoder).

About the MIDI encoder from DTS:

This takes a wired key input and outputs a MIDI signal. The main circuit boards handle 64 keys + 24 pistons + 4 swell shoe potentiometers on one board. It can optionally control 64 stop controls + pistons +pots. (The difference is that stop controls are on continually; keys are given an ON signal and an OFF signal.”

I also have a Pinterest board with all sorts of useful info, images and ideas pinned up:

Hauptwerk AGO Organ Project: Sites that would help me put together my own Hauptwerk organ
