How To Get Into Digital TV

1 Mar, 2008

Perhaps you are blissfully unaware of it - but the Australian Government plans to progressively switch off all analog TV transmitters, starting in less than two years time. And High Definition digital TV programs are now being shown on "free to air" commercial, ABC and SBS TV. Those programs are not available via Standard Definition digital tuners or set-top boxes. So what do you need to do?

How To Solder Surface Mount Devices

1 Mar, 2008

Many electronics enthusiasts hesitate to build projects involving surface-mount devices (SMDs) because they're daunted by the prospect of soldering such tiny parts to a PC board. But it can be done. Jim Rowe shows us how...
