A pusbutton doorbell with an elaborately styled bellpush based on imagery of the Black Land.
For each visitor, only the first press is registered. Subsequent presses are ignored by the control unit, ensuring that the there is only ever One Ring.
There is no "OFF" switch. To deactivate, throw entire assembly into an active volcano.
(Originally titled "Sauron Doorbell")-- 8th of 7, Apr 21 2020 "Glass Eye" doorknob _22Glass_20Eye_22_20doorknobInspired by [pert]'s comment. [8th of 7, Apr 21 2020] More Cowbell https://www.youtube...watch?v=cVsQLlk-T0s [theircompetitor, Apr 24 2020] You want me to transfer the bun you got - for that One - in the other post, to here ? :D-- FlyingToaster, Apr 21 2020 No need, please leave space for the deluge of croissants that others will shortly bestow...-- 8th of 7, Apr 21 2020 To be fair, I thought that was funny. I know, I'm easily amused.-- wagster, Apr 21 2020 Well, the standards here are not high to begin with, so no real need to apologize.-- 8th of 7, Apr 21 2020 Surely you need some stone watcher sentries with motion sensors that trigger a harsh clang, a la Cirith Ungol.-- RayfordSteele, Apr 21 2020 With a brace of cave trolls to open it; I'm not going to.
(They *do* have a cave troll, don't they?)-- lurch, Apr 23 2020 You could hide the key under the Balrug.-- 2 fries shy of a happy meal, Apr 23 2020 Haha.
Just stand in front of that post, [2fries]. Yes, that's the one, with all the bullet pock-marks on it.
Do you want a blindfold ?
// Cirith Ungol //
Ah, Sir wishes to purchase one of our Animatronic Giant Spider gate-guards ?
// They *do* have a cave troll, don't they? //
Not currently. [UnaBubba] has left the building.-- 8th of 7, Apr 23 2020 //For each visitor, only the first press is registered.//
So not just one ring then, but lots of rings, one per person.
Kind of defeats the pun
Oh I forgot , I should have gently explained that most humans have more than one person come to their door over the course of their time living at that address.
For a true single use doorbell I would have thought an explosive charge to actuate the hammer would be more effective and would guarantee the lack of subsequent rings.-- pocmloc, Apr 23 2020 They arrive, but they never leave. So, one per person.
Yes, an explosive charge is often involved.-- 8th of 7, Apr 23 2020 //Do you want a blindfold ?//
Well how am I supposed to control the ricochettes if I can't see?Tsh!Unintended people would get slaughtered at random.
You're new to this super-hero stuff aren't you?-- 2 fries shy of a happy meal, Apr 24 2020 I thought this was some play on More Cowbell-- theircompetitor, Apr 24 2020 I assume there's an unreasonably bright dull orange spotlight which piercingly illuminates whosoever dares press the doorbell and tracks their movements as they back away slowly off-premesis.-- sninctown, Apr 24 2020 They tend to hang around for a bit to use the bootscraper, after their slog through the Dead Marshes...
// Unintended people would get slaughtered at random. //
Yes, but there could equally well be a downside.
// You're new to this super-hero stuff aren't you? //
We're more familiar with the various Kirk/Picard/Sisko/ Janeway/Archer methodologies, which are pretty consistent. Turning superhero is like Q showing up unannounced - as usual - and cheating at everything, "because he can". Git.-- 8th of 7, Apr 24 2020 <shrugs> Well we work with what we have been left to work with now don't we?...
Okay maggots, line up! Who wants the first ricochette?-- 2 fries shy of a happy meal, Apr 25 2020 //unreasonably bright dull// Yes I think that could be a very useful kind of spotlight.-- pocmloc, Apr 25 2020 Good one (at last!) [+] but shouldn't repeated pressings result in the finger being stabbed by a needle, with the subsequent blood samples retained for future mischief?-- xenzag, Apr 25 2020 To be consistent with the idiom, the tip would have to break off the needle and work its way into the victim's heart, turning them into a Ringwraith.
// Good one (at last!) //
