It has been along while since I have dug out my RCX and brushed up on my NQC
skills. Also having a fascination for old clocks and watches and I wanted to
build a RCX controlled clock for work. I found Ben Williamson's web page
for a Lego Analog Clock and decided to give a whirl. Needed to redesign a
little using the Mindstorms rotation sensor and update the NQC code. 20
minutes of construction and 30 minutes re-doing the code, it runs fine. In
case anybody wishes to try it also, the updated code is below. No pictures
at the moment, soon on Brickshelf.

Ben's original design
http://unite.com.au/~u11235a/lego/clock/index.html
New code:
#define ROTATION SENSOR_1
#define MOTOR OUT_A
#define STEP 1 /* set to 1 for 1/16 rotation */
int curr_watch; /* set up of variables */
int old_watch;
int temp;
sub step() /* step clock one time increment */
{
OnRev(MOTOR);
while (ROTATION < STEP);
Off(MOTOR);
ClearSensor(ROTATION);
}
task main()
{
SetSensor(ROTATION, SENSOR_ROTATION);
ClearSensor(ROTATION);
SetPower(MOTOR, 1);
SetSleepTime(0); /* do not power down */
old_watch = Watch(); /* get clock from rcx */
while(true)
{
curr_watch = Watch();
if( curr_watch != old_watch )
{
old_watch = curr_watch;
temp = (curr_watch / 5) * 5;
if (temp != curr_watch)
step();
}
} /* end of while loop */
} /* end of main */
