Hi Robert,
 
Next week's meeting details are below:
 
Tuesday 9 October - Programming -  N. Hoffman - 5:30pm - 8:30pm
At the September meeting Andrew discussed using a PIC as a proximity sensor. He referred to the Microchip application note AN1202 "Capacitive Sensing with PIC10F". It explains how to use the PIC's internal analogue comparator and an external diode as a relaxation oscillator so that an external capacitance changes the oscillator frequency, which can then be sensed by using timer 0 in the PIC. Almost any PIC device can be used for proximity sensing, he said.
Lino recommended Aztronics of Adelaide as a source of small quantities of surface mount parts. Talking Electronics was also recommended as a source. Its website also offers a starter kit of common surface mount parts and a matching PC board.

Paul spoke of his interest in dsPIC Digital Signal Controllers. A DSC combines the control attributes of a microcontroller with the computational and throughput capabilities of a Digital Signal Processor to produce a very powerful microcontroller. 
 
Members of the group will demonstrate some new microprocessor applications and programming examples at Tuesday's meeting. Visitors are always welcome.                                                                                                                                        Neville Hoffman
Friday 12 October - Seniors - 9:30am - 12:30pm
The club's computer has stopped working and it is to be rebuilt. Members who attend this meeting will be able to watch the first steps of the rebuilding process in an atmosphere that encourages discussion and learning. 
 
I f you would like to know more about the components in a computer and how they are assembled, this  meeting is a good opportunity for you to acquire some additional knowledge and learn some new skills.
 
Friday 12 October - Communications -  J. Lucke - 12:30pm - 3:30pm
John Lucke will discuss and show some photographs of the Wi-Fi "hot spot" setup he used while holidaying on the Gold Cost recently.
 
He will also review some of the "cloud" backup options currently available and discuss the pros and cons of using these services.
 
A question and answer session will be held at the beginning of the meeting.
~~~~~~~~~~~~~~~~~~~~~~~~~~
 
Cheers,
John Mathews
