Pictures will follow when there is something less abstract to detail.

Features

Core

Tweets when the Space is opened, as per user input. (Reading the code here might save some brain cycles)

Shamelessly plundered strings;

Format: (message)+(number selected on dial)+" hours"+(punctuation)+" (Until ~"+closing_hour:minute+")"
{
 {"The space is open to members! Someone will be here for about ", "an hour", "!"},
 {"The space will be open (to members) for approximately ", "1 hour", "."},
 {"Got something to make? There's someone in the space for the next ", "hour or so", "."},
 {"Makerspace! Open to members! For approximately ", "an hour", "!"},
 {"The Makerspace is open to members for around ", "an hour", "."},
 {"Get yourself down to the space and build things! Makerspace is open for ", "an hour", "."},
 {"Makerspace Members! There's someone at the space for at least the next ", "hour", "."}
}

On request, shuts down as much as possible and provides visual feedback/error reports based on the status of the Space equipment.

Can shut down:

3D Printers
 Turnigy
 Velleman
 Delta

 CNC?
The PC. Doable but might lose work, and is haltable by unsaved files. Notification & manual may be better.

Notification only:

Laser Cutter
2D printer
Heating?

Do we want to tweet when we shut?
