Silicon Chip - December 2011
by Silicon Chip
Just Arrived the new December Issue of Silicon Chip, with plenty of exciting, state of the art projects.
This month's projects include a digital audio delay for perfect Lip Sync, the use of an external sound system or
using the sound signal from your DVD/Blu-ray Player to the sound system, can result in the picture being out of sync with the
sound. This unit will solve this problem and allow the audio signal to match perfectly with the sound. Also this
month a magnetic stirrer, for those that love to brew your own beer, this is perfect. The unit produces a rotating
magnetic field and by placing a liquid on top of the unit, a resulting stirring action will be achieved. Finally this
month a simply adjustable voltage regulator to build, this unit works between 1.3V to 22V and is ideal for testing
or as a fixed supply instead of batteries.
This month's articles include a look at the plans to build a huge radio telescope in the Australian outback. By combining
a number of telescopes greater accuracy and resolution can be achieved. Connecting a large number of dishes over a wide
area connected with a high-speed network results in an array many kilometres in diameter and can observe and take measurements
of objects in very deep space. Also this month a look at some of the new Maximite clones on the market. These units
expand on the easy to program operating system and wealth of add-on units available for the Arduino series.
Together with the regular real life tales from the Serviceman's Log as well as the Circuit Notebook and your Questions.
