serial driven trigger...

[winstonsmith]

Hello,

Basically, I need to "pull" the trigger on a paintball gun with my
serial port. The gun has an electronic triger system installed, and all
I need to do is circumvent the pushbutton switch inside the handle...

I'm a total novice, and after some time searching, I haven't found any
relevant websites or schematics. Anyone have any ideas, or suggestions
for places to look?

You can do it with a resistor and an NPN transistor. Just put the
transistor in parallel with the switch similar to the IR remote
button on the below page.

Well, that seems easy enough. I assumed it would be, but was unsure if
I should be taking extra care not to introduce any extra current into
the circuitboard of the trigger... I assume this is accounted for?

Thanks for the reply...

If the switch is grounded that is. Otherwise use something like a solid
state relay, say LH1540 or similar.

How about this idea... instead of trying to circumvent the trigger
(space inside the handle is a huge factor), I'll switch the battery on
and off and adjust the trigger such that it's always depressed. I think
I have an idea of what this would look like, but unsure... any comments
on how this would be different?
