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.
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.
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! Any change of address should be notified to email@example.com
