Schematic is seen at 4:45. Based on simulation and my limited real world testing, this should work fine. If anyone thinks otherwise, please leave a comment! I was able to find project descriptions where people have made the phone ring OR read the hook, but not a single one that does both without modifying the phone's internals.
A fun and well done project. Bravo. Occasionally, you will also find a phone system controller box, at the thrift stores, as well. I forget the proper name for the device, but its functions were things like adding a "hold" line, directing a call to a particular extension, tying in the on-hold music system, etc. I wonder, if one of these boxes might be helpful?
Thanks! That sounds interesting device. Imagine having an intercom system at home (like Thomas Burns made in one of his videos) and being able to play on-hold music to the other person!
Disculpa pero esta mal tu circuito, el transformador debería ser de 600 Ω 1x1 = 600X600 Ω para acondicional la impedancia. Cualquier impedancia o capacitancia diferente el proveedor te retiene la linea.
Thank you for the feedback. I would agree with that, if we were connecting something to an actual landline / phone line that goes out to the exchange. But I don't know if ringer circuits should be used in that situation. Anyway, this circuit is used with phone that IS NOT connected to anything, other than this circuit... An isolated system. I should have mentioned that more clearly in the video.

I'd be really interested in getting one of these for a project I'm working on. Is the PCB available?
I am also wondering this or if we would need to design our own
