Next Month in Silicon Chip Advertising Index Getting Started with the Micromite, Part Three Allan Warren Electronics...... 103 In the third part of Geoff Graham's MMBasic programming tutorial, he covers some more advanced subjects such as data types, arrays and drawing text on an LCD screen. Altronics............................. 70-73 Industrial Robots Aussie Rechargeable Irons.... 11 Dr David Maddison takes an in-depth look at the history of industrial robots. He describes some of the amazing devices being used today to assemble vehicles, build bridges and many other tasks with a speed and precision that humans can't match. Blamey Saunders Hears........... 7 Micromite-based Direct Digital Synthesis Electrolube............................. 15 Using the Micromite LCD BackPack with a low-cost, pre-build DDS module to build a signal generator which can produce a variety of waveforms with an adjustable, precise frequency. Emona Instruments.............. IBC Automotive Electronic Fuse Sick of having to replace blown fuses? This electronic fuse works like a standard fuse except that it can be reset by pressing a button. Its trip current is set by changing a resistor value. It gives your circuit the protection of a fuse without the hassle. Note: these features are prepared or are in preparation for publication and barring unforeseen circumstances, will be in the next issue. The April 2017 issue is due on sale in newsagents by Thursday March 23rd. Expect postal delivery of subscription copies in Australia between March 23rd and April 10th. Notes & Errata GPS-Synchronised Analog Clock Driver, February 2017: the CP2102-based SC USB/Serial interface requires inverted signalling compared to the PICAXE programming cable, so the latest version of the software includes four different HEX files; two for clocks with stepping hands, for use with a USB/serial cable (04120217A) or PICAXE cable (04120217B); and two for clocks with sweep second hands, for use with a USB/serial cable (04130217A) or PICAXE cable (04130217B). By default, programmed micros are supplied with the -A versions; if you require the alternative version, please indicate this clearly at the time of purchase. Improved PICAXE Wireless Rain Alarm, Circuit Notebook, January 2017 (page 61): there are two errors in the circuit diagram published. A 10kW pull-up resistor was omitted between pins 4 and 1 of IC1. Also, the 0V rail of CON1 has no GND, leaving the filter capacitors isolated; they should be connected to 0V. High Power DC Motor Speed Control, January-February 2017: on page 66 of the February issue, the PCB overlay (Fig.4, at top) incorrectly labelled LK8 as HSS when it should be LSS; however, note that it was correctly shown in blue (indicating it is fitted for low-side switching).
