Silicon Chip May 2016

In this month’s May issue of Silicon Chip, build the new Senator Budget Loudspeaker System. The original Senator speaker system was quite expensive at around $1,700 per pair. This new budget system, has much of the same performance as the original but can be built at a much reduced cost. The speaker system is suitable for up to 60W RMS and has a sensitivity of 93dB/1Watt @ 1m. A high-performance woofer and tweeter is used, combined with a crossover unit built is a large sturdy, attractive speaker enclosure. Ideal for the music enthusiast, these speakers will deliver remarkable performance for a budget price.

Also this month, build a 230/115VAC 50/60Hz Precision Turntable Driver. This unit has a 12-15Vdc input and will deliver a highly accurate 220VAC or 110VAC output, making it ideal for use where a mains supply is not available. Also the unit delivers a reliable frequency supply, reducing the effects of frequency or voltage variation on the turntable and hence the music. Finally, this month a 4-Input Temperature Sensor Unit for the Raspberry Pi®. Four Dallas BS18B20 1-Wire Digital Temperature Sensors can be easily connected to your Raspberry Pi Board for temperature monitoring in a number of different locations.

In the features this month, an interesting article on Atmospheric Electricity. A look at the earth’s electric circuit and what causes lighting, as well as the Aurora. Also this month, a look at how to convert your old VHS Video tapes to digital format for storage on a DVD or computer. Analog video tapes only have a limited life and to avoid losing those precious family memories, a digital copy is essential. Plus all the regular columns, including the Circuit Notebook, Serviceman’s Log and Vintage Radio are included, providing stacks of great reading.
