WEEKLY SIG MEETING UPDATE 11 - 16 June 2012
1st Floor Sydney Mechanics' School of Arts 280 Pitt Street, Sydney http://www.sydneypc.com Sydney PCUG's Blog UPCOMING SIGs 18 - 23 June 2012 Tuesdays Seniors SIG Genealogy SIG Digital Photography SIG This week's Fridays Seniors SIG John Lucke's notes for his presentation to this week's meeting can be seen here. Alleycode HTML Editor 2.21 download... PageBreeze download... ASCCA's June Newsletter can be seen here.	Hello and Welcome, Details of next week's meetings are below: *Tuesday 12 June - Programming - N. Hoffman - 5:30pm - 8:30pm* At the May meeting we used Skype to enable Martin to view the proceedings from Dusseldorf. Alex used an omni-directional microphone that worked better for this, and donated it to the club. Michael showed a movie of his tea-making robot. It comprised several solenoids and servos actuated by PICAXE micros triggered by limit switches. Untriggered actuations were occurring, and after discussion it emerged that the microprocessor inputs were not tied to ground, allowing interference from electrical noise. The group advised connecting each input pin to ground with a resistor. Alex showed a circuit drawing and a PCB layout he drew with Eagle of a thermistor-sensing temperature controller with a Bluetooth connector to a PICAXE microprocessor. The group suggested changing the voltage ratings of some components to reduce the number of voltage regulators. David showed his programming tutorial website at www.gooligum.com.au/tutorials.html and discussed his recent revisions to cover the new MPLAB X development environment, the PICkit 3 programmer, and the latest Hi-Tech C compiler. Members of the group will demonstrate some new microprocessor applications and programming examples at Tuesday's meeting. Visitors are always welcome. Neville Hoffman *Saturday 16 June - Web Design - R. Hume - 1:30pm - 4:30pm* At their last meeting the members of this group looked at "Alleycode", a free HTML editing program recommended by Steve South. As the program looked impressive, the group decided to use it to start building a new web site at this month's meeting. Steve also demonstrated "PageBreeze", a free "WYSIWYG" HTML program, but you need to know your code to use it! There will also be a question and answer session at the meeting to discuss web page construction and any problems members may have encountered during the month. Links to "Alleycode" and "PageBreeze" are in the side column. ~~~~~~~~~~~~~~~~~~~~~~~~~~ Cheers, John Mathews Please remember if your e-mail address is changed for any reason at all, unless you tell me your new address you will not receive these weekly updates!
