Silicon Chip September 2008

This month we have an indepth look at the new high voltage DC power link between Victoria and Tasmania, this is the longest undersea power link in the world and enables power to be transported economically between the two locations. Both states have unique generating capabilities and requirements, this solution provides benefits in both directions. Also a look at the theory behind high voltage DC power transmission. Also a look at the new Metal Instaltest test station, ideal for mobile use with electricians or contractors, this unit measures and tests household wiring and can also generate a report necessary for safety standards.

This month’s projects include a new model train controller. This unit incorporates a number of new features over previous designs, including an infrared remote control, pulse power for extra smooth low-speed, LCD display with speed indication, simulated inertia and much more. The unit is quite easy to build and is housed in an attractive panel case. The unit is microcontroller based and is designed for use with 240Vac power systems. Also this month a simple LED flasher unit to build, with selectable operation characteristics, plus the assembly details for the high-performance 200W amplifier module, this module is both rugged and features remarkably low-distortion. The fourth part of the DSP Musicolour unit describes the construction of the remote control unit and the second part of the LED Strobe and Tachometer unit, includes the assembly instructions.
All projects come complete with circuit diagram and electronic parts list.
