Hello and Welcome,
Details of next week's meetings are below:
Tuesday 10 September - Programming - N. Hoffman - 5:30pm - 8:30pm
At the August meeting Alex showed us the Wiltronics website. Wiltronics has been appointed authorised distributor of Picaxe products in Australia. They also have a large range of Raspberry Pi bundles, books, accessories and peripherals.
Wayne drew a circuit to control kilowatt loads of high voltage from a small signal, as might come from a microprocessor. It uses mosfets in a darlington arrangement.
David demonstrated a PIC12F 8-Pin processor PCB he developed since the last meeting. It was designed to accept his plug-in peripheral boards such as buttons, LEDs, etc.
Members of the group will demonstrate some new microprocessor applications and programming examples at Tuesday's meeting. - Neville Hoffman
Friday 13 September - Seniors - 9:30am - 12:30pm
One of the most rewarding features of these meetings is what is learnt during the general discussion and question and answer sessions and once again there will be ample time for members to consider items of interest and concern at this meeting.
In addition, the role that mathematics plays in computer technology is well known, if not fully understood, and at this meeting the group will be given a gentle and light hearted look at how computers can be used to tease out solutions to one of the building blocks of mathematics that has been exercising minds since the time to the ancient Egyptians.
Friday 13 September - Communications - J. Lucke - 12:30pm - 3:30pm
John Lucke will discuss computer security at this meeting.
He will look at the range of security software currently available and, if time permits, consider the security options that come with modems, routers and wireless connections.
There will also be a question and answer session to consider communication and general computer issues.
