HELP! Electronic sequencer for vintage door chime. Answered
Seeking any manner of help in making an electronic sequencer for a multi-note doorbell. I restore old door chimes and one particular model from the 1940's-1950's has an electromechanical linear distributor that works as the chime sequencer. It has a limited life expectancy- long since expired- and it defies repair. You can see details of this device by looking up patent number 2245443. The task to be done though is just like that of any more common chime sequencer that uses a rotary distributor. The idea is to replace the electromechanical mess with modern electronics to time the power sequence to three or four 16v or 24v solenoids. Looking for any helpâ¦ guidance, advice, moral support... but mostly hoping to find someone who can design and build a few of these, as I am largely clueless about electronic design.
