I had thought in the public arena, possibly the big end of town .

Adam suggested the big media end of town. eg. NYT building. Here we have fairfax and ACP in the CBD and News in Surry Hills . Perhaps a corporate lobby type area .

Perhaps Terminus projects would be able to broker something like this .

import serial # if you have not already done so
import sys

# 	usage :
#	python _stepper.py -1 S
#	1 step counter clockwise

#	python _stepper.py 12 R
#	12 revs clockwise

#	bitmask for revolutions
revs = 128
#	bitmask for clockwise / anticlockwise

	l=[]
	while(n>0):
		l.append(str(n&1)); n=n>>1
	return "".join(l[::-1])
	
	
r = int(sys.argv[1])

if ( r > 0 ):
#	its positive
	r = r + pos + revs
	print "`Clockwise,",
else:
	r = r * -1
	r = r + revs
	print "`Anticlockwise,",

print abs(int(sys.argv[1])),

if ( len(sys.argv) > 2 ):
	if ( sys.argv[2] == 'S' ):
		revs = 0
		print "Steps\'"
else:
	print "Revolutions\'"


ser = serial.Serial('/dev/tty.usbserial-A1000gh8', 38400)
print "binary " + binary(r)
print "int    " + str(r)
print "char   " + chr(r)
ser.write(chr(r))

Current stepper motor code.
Expects:
1 byte in via USB
a 1 in the first bit for ‘revolutions’, a 0 for ‘steps’
a 1 in the 2nd bit for ‘clockwise’, a 0 for ‘anticlockwise’
the remaining 6 bits specify 0-63 clockwise or counterclockwise steps or revolutions

1. The stepper doesn’t have enough power to drive the slide bolt.
2. The stepper isn’t precise enough ( sometimes it misses steps ) to know where the bolt is
3. Mounting of the hardware

Additionally, the del.icio.us feed slows down this webpage considerably.
