CHRISTMAS SHOWCASE MS46121B Compact 1-Port USB Vector Network Analyzer CHRISTMAS STAR – Special offer for SILICON CHIP readers. Looking for something different this Christmas? How about this build-it-yourself musical Christmas Star from PICOKIT? Supplied with a pre-programmed PIC12F50 which not only controls the LED chaser pattern, it also has five popular Christmas carols which play in sequence and in sync with the 20 ultrabright wide-angle LEDs. It can even be controlled by motion with infrared motion detection. Normally great value at $24.20, for a limited time SILICON CHIP readers will pay only $18.70 – a 22% saving! You’ll find more information on the PICOKIT STAR on the PICOKIT website (see below) PicoKit - Maker Space Solutions Upper Caboolture 4510, QLD Phone: 07 5330 3095 www.picokit.com.au $AVE $20 The Aussie-made modular hearing aid is sweeping up awards You might remember Ross Tester’s review of Facett, the modular hearing aid by Blamey Saunders Hears, from the April edition of SILICON CHIP. Ross said, “The construction and battery connection is highly innovative. And they look pretty fancy too…” Since that review, Facett has received 12 awards for innovation and design, including the prestigious Australian Good Design of the Year Award and the CSIRO Design Innovation Award. Facett solves big issues preventing people from using hearing aids cost, stigma, and usability. Here are a few reasons it’s winning awards: It’s made for easy handling Facett uses silver-zinc rechargeable batteries housed in disconnectable modules which attach instantly, magnetically, to the hearing aid core (DSP). It enables affordable upgradability Instead of buying a new hearing aid model, Facett users can access new features by buying add-on modules that work with the original core. It’s user-programmable      The award winning IHearYou® app lets users control their        listening preferences and program the hearing aid        themselves, on a smartphone, tablet or computer, with        the same software used in clinic by Audiologists. For more, visit facett.com.au 64  Silicon Chip The MS46121B is a series of two PCcontrolled 1-Port USB   ShockLine Vector Network Analyzers with frequency ranges of 40MHz to 4GHz and 150kHz to 6GHz. The MS46121B provides performance and accuracy for your one port measurements in a low cost and space saving solution that is small enough to directly connect to the device under test. All the members of the MS46121B series are aimed at RF and microwave applications in manufacturing, engineering and education. The two MS46121B options both come with 120 microsecond per point sweep speeds and a measurement accuracy of ±0.5dB (-6dB offset, typical), making them suitable for your passive device test applications. These new very compact VNAs are externally controlled via USB from a user supplied PC. Up to 16 independent MS46121B VNAs can be operated in parallel from the same computer running ShockLine software. This enables true parallel multisite testing of 1-port devices improving throughput over traditional single VNA and switch matrix test solutions.

Heavy duty, covered springs in the arm allows for easy manoeuvring with minimal force. The mag is surrounded by 60 high efficiency LEDS producing a maximum output of 850lm. What makes this magnifier unique is that the colour temperature of the LEDs are adjustable from 3500K to 6500K allowing the user to adjust the output to suit the environment or product being viewed. Supplied with a heavy duty clamp which allows the magnifier to be attached to a desk and a mains power supply is included RRP is $139.00 – however as an introductory special, for a limited time only the price has been reduced to $119.00.

The product (SC4003) has been specially developed to fulfil user requirements for a low viscosity, thermally conductive encapsulation resin with a wide operating temperature range. The user in question initially expressed an interest in Electrolube’s encapsulation resins for an LED based application but listed some specific requirements including a room cure system, a temperature range of -60 to +200°C and thermal conductivity of 1W/m.K. The customer also specified a requirement for a low viscosity system with good flow characteristics that would easily facilitate the potting of difficult and complex geometries and ensure minimal stress on components.
