PRODUCT SHOWCASE Marantz announce four new DVDs Three new high-performance DVD players have recently been released while a new entry-level model is due later this year. The Marantz Reference Series DV-18 is designed for the ultimate video and audio performance. It’s THX Ultra certified and features 10-bit/27MHz video D/A conversion, component video outputs and 96/24 audio capability. It is also equipped with Dolby Digital and DTS and has a full complement of viewing options and interactive capabilities offered by the DVD-Video format, including multiple camera angles and aspect ratios. Retail price is $2490. The $1790 DV7000 is similar but not part of the reference series, while the $1299 DV4000 is designed for spectacular home theatre video and surround sound audio quality. The entry-level DV3100 is expected to retail for around $1000. All Marantz DVD players also play back video CD and CD-R. D-BUS remote connection allows linkage to other Marantz components for inte- Oxley amateur radio field day The annual field “day” for the Oxley Region Amateur Radio Club Inc will be held on the Queen’s Birthday weekend, 10 and 11 June, at the Sea Scout Hall, Buller St Port Macquarie. Always a much-anticipated event amongst amateur operators from the Oxley region (and much further afield), the field day will feature amateur-oriented events, displays and demonstrations - and you could win a year’s subscription to SILICON CHIP! Field day opening times are 1.30 on Saturday and 8.30 on Sunday. For more information, contact the secretary, Alan Nutt, on (02) 6582 3557 or email anut<at>oze-mail.com.au An interesting case (or two)… Looking for somewhere to put all those bits and pieces? We reckon these two new component storage boxes from Jaycar are a real bargain! Both are priced at just $9.95, made from plastic and for that you get either a large (370 x 280 x 65mm), single sided case with 24 compartments, a flip-top lid and handle; or a smaller (290 x 305 x 70mm) double-sided case with 32 compartments (22 one side, 10 the other), two flip-top lids and a carry handle. In both cases (no pun intended!), some of the internal dividers are removable to give you larger, fewer compartments. If that’s still not enough space, we believe a little surgery on the fixed dividers would have the sizes and shapes desired. The lids are nearly transparent so you can see what’s inside before opening up. Apart from components, the cases would be ideal for small-ish test instruments (or large if you remove some dividers). The larger box is cat. HB-6314 while the smaller is cat. HB6315. You can see these storage boxes at any Jaycar electronics store and many of their dealers. They can also be ordered from Jaycar mail order (02 9743 5222) or web site (www. jaycar.com.au).­ grated system operation while features such as parental control, slow motion, freeze frame, multi-speed forward and reverse scan, chapter and track search functions are all standard. Marantz audio equipment is available at better sound and video outlets. For more information or the dealer closest to you, contact Jamo Australia on 1800 24 24 26. Compact digital scale At just 130 x 80mm, the new digital Pocket Scales from Dick Smith Electronics are just that: able to fit in a (well, OK large) pocket. They can measure up to 100g with 1g resolution – and with simple and fast calibration, they’re sure to find many uses in the home, office, business and industry. They feature a large, easy-toread LCD screen and are very easy to use. A carry pouch and set of batteries are included. The Cat Y-5039 Compact Pocket Scales are priced at $199 and are available from all Dick Smith Electronics stores, DSE PowerHouse stores, DSE Direct Link mail order (1300 366 644) or via the website at www.dse.com.au PLEASE NOTE Any prices mentioned in this issue are current for this issue only. The introduction of GST in Australia on July 1 will have an influence on many prices, particularly on items which are currently tax exempt. For prices after July 1, please contact the company concerned. JUNE 2000  33 “Y” Adaptors from Microgram Ever needed to run two monitors – or even two keyboards – from one PC?

The free DriveWay software, available for download from http:// mcu.motsps.com, enables the fast and easy integration of peripheral devices into designs and eliminates the need to learn the internals of each 68HC05 MCU derivative, resulting in faster development of higher quality applications. The key benefits of the Drive- Way software include an automatic assembly code generation for initialization code that automatically produces highly-tuned, fully-tested and documented code in minutes for each on-chip peripheral, while eliminating software, driver and initialisation software defects. Designers can now concentrate on generating their application code instead of the MCU configuration saving valuable development time. Another benefit is the point and click feature for setting up peripheral devices. In developing initialisation code and device driver interfaces, programming time can be reduced from weeks to minutes. DriveWay software is also de- signed to quickly confirm that an MCU can be configured for a specific application or suggest an appropriate one. It does this by selecting one 68HC05 from a group of 68HC05 MCU derivatives. In a matter of minutes, designers will be able to determine which 68HC05 provides the best solution. The first release of DriveWay software, available now, supports the most popular 68HC05 MCUs. Later this year, Motorola will be releasing DriveWay software for the 68HC08 and other MCU architectures.

JUNE 2000  35 Aussie DesignMark award to Power Tower Elsafe Aust r a l i a ’s P o w e r Tower, a clever stowaway unit designed to provide worktop access to power and data, was awarded an Australian Design-Mark at the recent Australian Design Awards in Sydney. By pulling the grommet lid up on the unit, access can be gained to up to four GPOs or two GPOs and four data circuits. Multiple power and data cables are neatly hidden away. Products which receive this award are judged on their functionality and how it relates to ergonomics, aesthetics, creativity, originality, safety and environmental considerations. Manufacturing (construction and use of materials), price, packaging and marketability are also taken into account. Over two years in development, the Power Tower was also awarded “The Product Most Likely to be Commercially Successful” award at the commercial furniture industry’s bi-annual awards. For more information on the Power Tower, contact Elsafe Australia on (02) 9975 7422; fax (02) 9975 4733. New Shure UHF wireless microphone receiver With the planned withdrawal of most VHF radio microphone frequencies to make way for digital TV, a new high-performance Shure UHF wireless microphone receiver from Jands Electronics is timely. The UP4 Portable UHF Receiver offers over 100 easily-selectable frequencies in a sturdy package designed for on-road use. It comes in an extruded aluminium chassis with a mounting box of solid aluminium alloy which allows battery changes without removing the receiver. A single 9V battery gives up to 10 hours of continuous operation. The unit has microprocessor-controlled predtictive diversity which anticipates dropouts before they NI’s worldwide measurement conference Want to escape Australia preOlympics? National Instruments might have just the place for you: Austin, Texas, the venue of its worldwide conference on computer-based measurement and automation. “NIWeek 2000 – Get Connected” takes place from August 16 - 18 at the Austin Convention Centre. We’re not sure about the mathematics of three days making a week but NIWeek is designed for engineers and 36  Silicon Chip scientists involved with measurement and automation applications, systems integrators and developers, instrument manufacturers and members of the NI Alliance Program. Eighty measurement and automation vendors will also show their wares in a major exhibition. If you’re interested, contact National Instruments for a copy of their INWeek 2000 CD which explains all.

With an adjustable ear-piece and boom microphone, the headphone plugs straight into many brands of cordless phones including many Uniden, Panasonic, Telstra and DSE models with a “stereo” 2.5mm socket. It automatically creates a “hands free” cordless phone for added flexibility in this latest generation of cordless phones which are superior in most respects to the lower frequency, and therefore shorter range, cordless phones which have been available for some years. Being digital transmissions, eavesdropping via a scanner is said to be impossible. While not suggested in the material occur and also has tone key circuitry to block other RF signals and noise squelch to prevent noise bursts. It is compatible with Shure’s UC and U series of UHF transmitters which include body-pack, lavalier and handheld mic options. And while on the subject of Jands Electronics, the company has recently acquired the agency for Stanton Magnetics, a US manufacturer of premium DJ products. They are a market leader in cartidges and stylii but also offer turntables, mixing consoles, headphones and CD players.
