This is my last update / post on this Arduino Tick Tock shield for now. I was going to post the details on how to calibrate the thermistor; including taking various measurements, recording the resistance at various temperatures, setting up the Steinhart-Hart Equation and solving it with matrix math, but I'm going to put that off for now.
Basically, this shield is a nice learning tool, with the real-time clock, thermistor, light sensor, display, buttons and LEDs to play with; but the RTC, the light sensor and the thermistor are of such low quality, that it's not really useful for anything more than "a toy shield" for learning and playing around.
The Ardunio Tick-Tock DS1307 RTC Shield was "fun" but not sure I recommend it to anyone, even for under $5 USD.
But on-the-other-hand, I did get my $5 worth playing with it so, as always, YMMV.

Hi,
I'm administrating a pretty old solaris (2.6) system. In the cronjobs I found that every night 2 o'clock a cronjob starts /usr/sbin/rtc -c. I've never seen this app in my life before so I looked at the manpage and it told rtc is for syncing Dos and Unix Systems. Did I understand it correctly?... (2 Replies)

I noticed in my cron log file for my solaris 8 servers the rc=1. I imagine that is return code and something did not process. Does anyone know what that is, is there fix or the implications of leaving it?
Thank you

This is a strange one, I've never seen anything like it; the realtime clock doesn't tick while the computer's idle, only when you're watching it. Leave for 3 hours and it'll be 3 hours off. It still advances when it's off however, or the time would be far more incorrect than it is.

Detailed Description
The SoAlarmSensor class is a sensor which will trigger once at a specified time.
SoAlarmSensor provides a convenient way of setting up triggers for jobs which should be executed only once when they are scheduled.
Constructor & Destructor Documentation
SoAlarmSensor::SoAlarmSensor (void)
Default constructor.
SoAlarmSensor::SoAlarmSensor (SoSensorCB *func, void *data)
Constructor taking as parameters the sensor callback function and the userdata which will be passed the callback.
See also:
setFunction(), setData()
SoAlarmSensor::~SoAlarmSensor (void) [virtual]
Destructor.
Member Function Documentation
void SoAlarmSensor::setTime (const SbTime &abstime)
Set the time at which the sensor will trigger.
Note that you must manually schedule() the sensor after calling this method.
See also:
setTimeFromNow(), getTime()
void SoAlarmSensor::setTimeFromNow (const SbTime &reltime)
Set the alarm to be at a specified offset from the current time.
Note that you must manually schedule() the sensor after calling this method.
See also:
setTime(), getTime()
const SbTime & SoAlarmSensor::getTime (void) const
Returns the trigger time for the alarm as an absolute value from 1970-01-01 00:00:00.
See also:
setTime(), setTimeFromNow()
void SoAlarmSensor::schedule (void) [virtual]
Put the sensor in the global timer queue.
