Meetings During the Week 11 - 16 May 2015
1st Floor Sydney Mechanics' School of Arts 280 Pitt Street, Sydney http://www.sydneypc.com Sydney PCUG's Blog 18 - 23 May 2015 Tuesday Forum Family History Digital Photography SIG Review: Raspberry Pi 2 Model B Read the review here. ASCCA May Newsletter can be read here. What is Mu-Mimo? Find out here.	Hello and Welcome, Details of next week's meetings are below: *Tuesday 12 May - Programming - N Hoffman - 5:30pm - 8:30pm* At the April meeting Martin showed a circuit board he built to run as a RFID card reader. He also discussed a problem with a circuit for a power supply to a servo. Geoff showed a power supply he bought on eBay. With independently adjustable voltage and current over a range of 0-30v, it was good value at $65. Alex explained how he obtained an Amateur Radio Certificate. He bought the amateur radio Standard License course from the Radio and Electronics School, http://res.net.au/. The course has a wide range of useful information and tests, and offers a CD giving a good introduction to radio and electronics. As well, he joined the Waverley Amateur Radio Society to learn more about the subject. A forthcoming meeting of the Ozberrypi meetup group was announced. You can see summaries of the previous meetings at: http://www.sesame.com.au/picclub The members will have some new microprocessor applications and programming examples at Tuesday's meeting. *Saturday 16 May - Web Design - S South - 1:30pm - 4:30pm* This month the group will look at "responsive design" which is the process that enables websites to be viewed on devices that have different screen sizes such as desktop computers, tablets, mobile phones and even smart TVs. The group will examine what makes a website responsive and that is mainly concerned with scale. At least four factors are involved: 1. the design of a scalable layout; 2. the use of a scalable font; 3. the use of scalable images; and 4. the arrangement of items to fit on the screen that is being viewed. The main factors that need to be considered to achieve the desired design appear to be: 1. developing a fluid page structure by using percentages to make fonts scalable using "emphemeral" units or em's; 2. convincing the browser that the image is scalable; and 3. using media queries to find out what screen size is being used and then moving the elements of the page to fit the screen. The group will also look at how to convert an existing fixed website to a responsive one. ~~~~~~~~~~~~~~~~~~~~~~~~~~ John Mathews

Saturday 16 May - Web Design - S South - 1:30pm - 4:30pm

This month the group will look at "responsive design" which is the process that enables websites to be viewed on devices that have different screen sizes such as desktop computers, tablets, mobile phones and even smart TVs.

The group will examine what makes a website responsive and that is mainly concerned with scale. At least four factors are involved:
1. the design of a scalable layout;
2. the use of a scalable font;
3. the use of scalable images; and
4. the arrangement of items to fit on the screen that is being viewed.

The main factors that need to be considered to achieve the desired design appear to be:
1. developing a fluid page structure by using percentages to make fonts scalable using "emphemeral" units or em's;
2. convincing the browser that the image is scalable; and
3. using media queries to find out what screen size is being used and then moving the elements of the page to fit the screen.

The group will also look at how to convert an existing fixed website to a responsive one.
