Hi All

Here's one for the think tank.....
One of the guys a work is building a house [and on a very steep hill by the 
sounds of it.]

He wants to install a 3 stop dumb waiter from the kitchen (Top floor) via the 
laundry (gnd floor) to the Garage. (basement)
for shopping. I believe the original plan had the void as a laundry chute and 
he has just reversed the access from the
linen press to the pantry so it can be used for groceries as well as clothes.

He is thinking about a gate controller and motor (The sliding kind) as it has 
already got stops for full open, full closed and partial
open option for pedestrian access.

I was thinking about the cheap winches from the automotive shops and a PLC 
(programmable logic controller) as some year ago
I saw a developer board that had reversible high amperage mosfet motor control 
plus switch and sensor inputs. Plus this has some software
so it could be programmed by drawing a flow chart.



NOTE: A real electric dumb waiter set-up would cost more than hiring a teenager 
to carry the shopping upstairs weekly for about 7 years.
 

Cheers 
Rod
