Silicon Chip May 2017

In this month's Silicon Chip Electronics Magazine, build the upgraded Marine Ultrasonic Anti-Fouling Unit. This easy to build unit is ideal for boats up to 14m and can be used with fibreglass, steel or aluminium hulls. The unit will greatly reduce the amount of algae and marine growth on your boats hull, improving speed, fuel economy and the need to remove the boat from water regularly for cleaning. The unit is powered from the boats battery and is housed in a solid waterproof pvc box. The unit can also work unattended for many years and provides visual indication for operation, low battery and faults.

Also in this month's projects, build a RF Prescaler for radio frequencies up to 6GHz. If you already have a frequency counter up to 10Mhz, you can add this compact unit for expanding the frequency range. Finally this month, build the Microbridge, an inexpensive PIC32 programmer. This miniature unit connects to the USB port of your computer and can be used to download programs directly to a Micromite or other PIC32 Microcontroller. All projects come complete with circuit diagram and electronic parts list.

In this month's main feature a look at Industrial Robots, these have virtually taken over the modern factory and are expanding into new areas at a fast rate. This article looks at some of the theory behind their operation and also some of the new areas and applications the robots are being used for. Also this month, a look at tyre pressure monitors. These amazing devices simply replace the tyre caps on each of your tyres and transmit the tyre pressure to a display inside your car. Plus all the regular columns, including the Circuit Notebook, Serviceman's Log and Vintage Radio are included, providing stacks of great reading.
