ON-OFF Control for a Gun

[knightlife]

Here is a technique for controlling a gun which uses the Heisenburp reaction.

p60 HWSS gun uses a glider to turn on and another one to turn off:

Turning the gun on when it is already on does not disturb anything.
Turning the gun off when it is already off does not disturb anything as long as the "off" gliders are not consecutive (60 tics apart).If the "off" gliders are consecutive then there will be an escaped glider for each consecutive "off" glider.
That is the only condition where the isolated eater is needed, unless you want to use the escaped glider to detect that condition!

Note that once you have a controlled gun, it can control another gun of a different type as long as the streams can annihilate each other. Now the "on" glider becomes the "off" glider of the composite gun and vise-versa.

The HWSS gun is from Jason Summers' collection.
I found this technique while trying to do something else (as usual).

Very cute, knightlife!

There's a p120 switchable gun in my Glider Circuits thread, but it uses a single glider stream for the switching (using a boat-bit). More recently, I posted a p150-p300 double gun, where the p120 stream is switchable be means of a blinker, but this is harder to control, as it's a lot easier to destroy the blinker than it is to synthesize one in the proper location.

Here is a totally different on-off p60 HWSS gun:

It is amazing it even works, definitely unique, but the previous one is better.

Hey, maybe it can be used for LWSS to HWSS promotion:

Nah! Too slow! It also requires the matching glider that cannot be a gun.

I've done something like this at p30 with LWSSs. I'll have to dig that up and post it. Makes a great latch. You can set or reset it from almost any direction.
