[Noisebridge-discuss] Elevator wiring drop

based on what I heard about the radios having been already programmed for 
a jail frequency for which we are not lisenced, even I think its not 
appropriate to use them in a fixed location such as our collective.

I don't know if we will be able to re-program these radios at all without 
some unfree software and proprietary cables, although maybe we could copy 
the software and cable designs from a radio shop which would cooperate.

We can certainly install a pair of radios tonight for temporary use, but I 
think the correct solution for the elevator long-term is a wired callbox, 
and I think it should be easy to run a wire without too much hassle.

A single cat-5 cable would provide enough wires for a callbox (four) and 
still have another four wires left over for an actual ethernet connection 
should we decide to get fancy and put a little PC down there with a camera 
and door-access keyboard etc. someday.

Another option for elevator love is to install a little dinger-chimer 
thing which "reminds" people that the red light is on upstairs, meaning 
the elevator needs to be "jiggled" so that it can be called downstairs.

Another option would be to move the microswitch on the elevator rails a 
quarter or a half inch higher, because whats happening right now is that 
the elevator stops moving upward because of switch A but before pressing 
on switch B which is the one that allows the elevator to be called.
But that's probably something we are not supposed to be messing with.
