PRODUCT SHOWCASE Christmas Motif Lighting from DSE and Jaycar If you’ve always been a teensy bit envious of Chevy Chase’s home in Christmas Vacation, Dick Smith Electronics and Jaycar stores could be the place to head this festive season. Both are offering rages of Christmas motif lighting in various patterns and sizes, ranging from $19.90 for small patterns at Dick Smith Electronics up to $449 for a 184cmlong Santa Sleigh at Jaycar. The DSE models are for indoor use while the Jaycar displays are suitable for outdoor use as well. Alternatively, of course, you could build the microprocessor-controlled LED Christmas tree featured in the November issue of SILICON CHIP. Jaycar Electronics also have this kit in stock, selling for $49.95 (Cat. KC-5280). Flow, valve & position sensors A range of sensors of interest in organisations involved in gas and fluid handling have been announced by Melbourne company, ifm efector Pty Ltd. First is a pressure sensor with high, low and window alarm outputs. They cover the pressure range from 1 to 400 Bar, operate from 18 to 30V DC with outputs rated at 250mA. Programming is via push buttons. The centre photo is ifm efector’s new gas/liquid flow sensor, suitable for zone 1 hazardous areas. Made from 316Ti stainless steel and with integral ANSI B 16.5, 1-inch flanges, they operate to Eex 1a IIC T4 standards. Setting ranges are 3-300 Emona Y2K Cat Emona Instruments has a new 88-page Year 2000 catalog covering not the dreaded “bug” but instrumentation and equipment for electronics and electrical design, manufacturing, service and education. Many of the world’s leading test equipment manufacturers are represented including Tektronix (for whom Emona are a distributor), GW, Thurlby Thandar, Kikusui, Seaward, Escort, Nicolet, Stag and Weller. The catalog is free on request to (02) 9519 3999 or email testinst<at> emona.com.au cm/s (liquids) and 100-2000 cm/s (gases). The third photo is one of their new valve position sensors which easily fit to most standard valve actuators. There are various versions including standard versions and hazardous-area versions rated to IP67. For more information, contact ifm efector Pty Ltd, PO Box 4084, Auburn South, Vic 3122.

Precision Handheld Thermometers from Fluke Fluke Australia have released a new range of hand-held thermometers particularly suited to applications in the food and process manufacturing industries but also having electronics industry applications. There are 7 models in the new series ranging from the low-cost 50 II series (pictured) through to the 54 II which, along with the 53-II, features powerful logging capabilities and a PC interface. Accuracy is within 0.05% +0.3°C. 28  Silicon Chip All models can handle a much wider range of thermocouples than the previous 50 series. They are also splash and dust-resistant and each has a holster for protection. Included in the range is an infrared model which requires no physical contact with the item being measured. This is intended for applications where contact could be hazardous or the item is moving. A laser beam is incorporated to assist aim and accuracy is within 1°. There is a comprehensive range of accessories available. For further information contact Fluke Australia, 26/ 7 Anella Ave, Castle Hill NSW 2154.

It can also be used to match individual cells in battery packs for optimum capacity. Connection to the PC is via any available serial port, which the software automatically detects. Operating range is from 1.2V to 48V 30mAh to 130Ah with adjustable end of discharge voltage from 0V to 48V ad discharge time range from 1 minute to 30 hours. It also calculates and displays optimum discharge voltage. The graphic display shows curves for capacity in mA.h and for discharge voltage. It also shows percentage of nominal capacity, energy in watt-hours, elapsed time, maximum discharge time and discharge current, plus end of discharge voltage. 60VA to 3KVA encased toroids The program also calculates and displays the optimum end of discharge voltage for each battery. The battery is discharged through a resistor – from 0.01Ω to 50kΩ, or an optional constant current sink from 5mA to 2000mA. The software runs on any PC with either DOS or Windows and a VGA display. For further information contact Smart Fastchargers – Phone 03 6492 1368, Fax 03 6492 1329, email smartfastchargers<at>bigpond.com Video microscope for industrial uses The new Chroma 7310 Video Microscope from Nilsen Technologies is ideally suited to electronics manufacture and general quality control applications. It’s a CCD-based camera which provides distortion-free images. An advantage of this approach is that multiple-viewing is possible, frames can be frozen and the image can be recorded to a VCR or PC fitted with a video capture card for archiving purposes. The magnification range is from 20x to 300x with a large depth-of-field, making a very versatile instrument.

Harbuch Electronics Pty Ltd 9/40 Leighton Pl. HORNSBY 2077 Ph (02) 9476-5854 Fx (02) 9476-3231 New semis from REC REC Electronics have released three new semiconductors of interest to professionals and hobbyists alike. The new Zetek Schottky barrier diodes in miniature SOT323 and SOD-323 packages offer space savings of up to 60% over comparable SOT23 devices. Suitable for a wide range of detection, mixing and modulation tasks at UHF, they feature low forward voltage (410mV <at> 1mA max) and high breakdown voltage. Also released are new micropower low dropout linear regulators (300mV dropout) suitable for a range of portable equipment, with fixed outputs of 2.5V, 3.3V or 5V or adjustable between 1.22V and 20V. Finally, the Linear Technology A1, 600kHz boost switcher delivers 28V for TFT liquid crystal displays. For more information, contact REC Electronics, Locked Bag 29, PO Rydalmere NSW 2116.

It’s the mechanical construction system that has enthralled children and adults alike for generations. Strips, girders, nuts, bolts, brackets, wheels, axles, gears and pulleys – they used to say if it could be made it could be made with Meccano. Now it’s back – at Dick Smith Electronics. With impeccable timing, given the Jolly Red Suited Chap is only days away, all DSE stores (including PowerHouse stores) have Meccano kits ranging from easy-to-build through to engineering level. All come with a motor to make things that actually “do things”.
