Latching RC module?

  • Latching RC module?

    Is anyone aware of a drop-in module that will take a proportional RC channel and latch output for a servo?

    While the VEX radios are great, they have no latching channels, so implementing things like torpedo tube doors are tricky. It would be great to find an in-line unit that could hold the latch until you moved the stick in the other direction...

    This should do it. https://engel-modellbau.eu/shop/en/R...dule-MINI.html

      That looks like a relay. Lots of those around. I'm looking for a servo output (unless I'm reading the description wrong, of course).

        I am pretty sure that this is what you are looking for-although I am not 100% about the latching-but I can't see how it could work without latching

          And...I now see that its no longer available-But similar units are made by other manufacturers..

            Have a look at servo controllers. Typically you use a switch or button to activate servos, so by using a switch channel expander like the one in the second post, you can activate servos to and thing you want - one doors, fire torpedo, close door with one one switch.

              That's the way to go, and the Pololu kit have excellent instructions. A big advantage is you can also program things like time and motion curves for the servos for more realistic looking actuation.

              many folk also doing similar things with Arduino boards, but probably a bit more involved than the Pololu option, and you won't save a lot of money anyway.

                Dude,

                I know it might be a cheesey solution, but if this is specifically for the Torpedo tube muzzle doors, how about they actuate a switch at the max open point to launch the fish? Granted the opening mechanism would require finesse for proper timing. But it would be one operation, open and shoot. Unless you want to run with doors open. This is my solution for the fish on the 722.

                You can use electrical solenoids....the old (darn that 90's tech) SubTech SES-II Electronic switches could be set momentary or latching. If they could even be found. Wonder what ever happened to that old Company and if the tech could be retrieved??.....lol.

                  The Pololu micro maestro can easily be configured to switch outputs on and off, latched or momentary. Alternatively, if you don't mind rolling your sleeves up, you can get something like an Arduino nano board for a couple of quid on ebay, and that gives total flexibility, permitting a dozen or more channels from a single R/C channel to do whatever you wish.

                    I wonder if one of these would work, http://battlersconnection.com/electronics/
                    the battle boat crowd use solenoids. The pump switch is cool too!
                    If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.
