• Welcome to the Pipe Organ Forum! This is a part of the open community Magle International Music Forums focused on pipe organs (also known as "church organs"), organists, organ music and related topics.

    This forum is intended to be a friendly place where technically advanced organists and beginners (or even non-organists) can feel comfortable having discussions and asking questions. We learn by reading and asking questions, and it is hoped that the beginners (or non-organists) will feel free to ask even the simplest questions, and that the more advanced organists will patiently answer these questions. On the other hand, we encourage complex, technical discussions of technique, music, organ-building, etc. The opinions and observations of a diverse group of people from around the world should prove to be interesting and stimulating to all of us.

    As pipe organ discussions can sometimes become lively, it should be pointed out that this is an open forum. Statements made here are the opinion of the poster, and not necessarily that of the forum itself, its administrator, or its moderators.

    In order to post a new topic - or reply to existing ones - you may join and become a member by clicking on Register New User. It's completely free and only requires a working email address (in order to confirm your registration - it will never be given away!). We strive to make this a friendly and informative forum for anyone interested in pipe organs and organ music.

    Many kind regards

DIY-Reversible Piston Control

JayR

New member
This is for the do-it-yourselfer members of this forum...

If you ever find yourself working on an organ console MIDI conversion, and you come across the need for a solid-state version of a reversible piston control, here it is! The attached PDF file contains the silkscreen and etch patterns to make a reversible piston control printed circuit board. So, if you know how to etch your own printed circuit boards, feel free to use the patterns I have provided.

This circuit uses an array of solid-state relays to make a thumb or toe piston function as an on/off switch. It can be useful for controlling a zimbelstern, a sfortzando, or any other organ function that requires a reversable piston trigger.

Have Fun!
Jay
