Adding (triggering) reversibles

Postby engrssc » Sat Jul 28, 2018 4:45 am

For a buck and change:

https://www.ebay.com/itm/New-5V-Flip-Flop-Latch-Relay-Module-Bistable-Self-locking-Switch-Trigger-BLU-/392066315410

For mounting, I use Velcro. Altho it says 5VDC, spec says power supply input can be 5 - 12 VDC via the regulator of course. Easy triggering by a thumb or toe piston. Module has a built-in switch for testing.I also extended the built in (relay) LED to drive a lighted piston. BTW, I converted all of my lighted pistons to LEDs vs the normal 5 volt incandescent bulbs..

There are 3 pin push on Phoenix connectors available for screw term connections. Found the cheapest ones to be https://www.ebay.com/itm/10-pairs-3pin-Male-Female-Phoenix-Blocks-Connector/350488381218?hash=item519abc4722%3Ag%3A328AAOxyakdREO0F&_sop=15&_sacat=0&_nkw=3+pin+Phoenix+connector&_from=R40&rt=nc which pairs of female and male. You can use just the female connectors and forget the male chassis pieces.

For Hauptwerk reversible pistons, you only need to have a simple "switch" which sends a midi signal (for example note on / note off). Hauptwerk internally deals with handling the state of the stop(stops) being reversed and sends the appropriate "stop on/off" signal to the affected stop(s).

I'm aware of that, but I wanted the light signal and I do other things with the relay outputs.
