PRODUCT SHOWCASE Your old analog TV not receiving much these days? Contact: Altronics Distributors Despite analog TV transmissions having progressively ceased right across Australia (the last in 2015), many people have “hung on” to their old analog TV sets – for a variety of reasons including the fact that their even older VCRs etc still worked. Many others have them in a wall unit or display cabinet where a modern slim-line digital set might look completely out of place. For these people (and it must be said for many other reasons) Altronics have released two high definition (HD) Digital Terrestrial Set Top Boxes from Dynalink. The “Digital” part means it receives all digital television channels; the “Terrestrial” bit means they’re intended for land-based (as distinct from satellite) transmissions. The first of the two, the Dynalink A 2809, is tiny at just 120 x 90 x 27mm. While a 12V DC plugpack is included, as it’s powered by 12V DC it is obviously intended for a “mobile” market – caravanners, campers and mobile homers, the boating fraternity and the like. Output is either HDMI or A/V (composite). (Head Office): 174 Roe St, Perth WA 6000 Tel: 1300 797 007 Web: www.altronics.com.au It has an infrared remote control (included) and despite its compact size, a full range of user controls including EPG, program selection including favourites and recording (via USB to an optional stick). It is compatible with DVB-T and MPEG-4 AVC/H.264 HP<at>L4. Recommended retail price is $79.95 The secondset-top box is the Dynalink A 2856, which is mains powered. A little larger (220 x 160 x 40), this one is aimed at the home market, where the set-top box really can be on the top of the set! It has all the features of its little brother and a few more besides, such as coax and Cr/Pb and Cb/Pb connections along with stereo audio and video plus HDMI. Similarly, an infrared remote control is included and it too sports a USB port for recording. This one is slightly cheaper at $69.95. They are available through all Altronics stores and resellers. Five Smart Gadgets To Turn Your House Into A Smart Home We’ve unearthed five interesting “appliances” guaranteed to turn your house into the smart home of the future. Some are so new they’re not yet available in Australia but we believe they’re not far away!

Additionally, they follow the same strict procedures as full production PCB Assembly orders on Prototyping PCB Assembly orders so that customers can evaluate the project’s function and performance. Here are their specific procedures of their full turnkey PCB assembly service: Step One: Give a custom quotation based on your PCB design file & BOM, then confirm with you about the price and rough build time. Step Two: If you’re OK with the quotation and lead time, they’ll move forward to run a DFM check and review your PCB design file for possible issues that may affect manufacturability. As soon as any issue has been detected, they’ll get in touch immediately to solve it with you. Step Three: When those detected issues are fixed, they’ll begin component procurement and PCB manufacturing procedures. Step Four: Then, they’ll start populating components on those boards exactly as you designed. Additionally, X-ray inspection, 100% AOI test and X-ray test for BGA, IC programming, Components cost-down and Function test are all available as custom options. They’re now offering EXTREMELY low PCB assembly labor cost if you let them fabricate and assemble PCBs at the same time. Have a project ready for prototyping?

Bad luck if you’re not in the USA. Unless . . . Microsoft’s HoloLens has been getting some rave reviews in the US . . . even at $US3000, virtual reality enthusiasts (even in Australia) have been clamouring to get their hands on one! But the HoloLens has been released only in the US – they won’t sell one to an overseas address. So if you REALLY must have a HoloLens, the trick is to get your own US address! siliconchip.com.au It’s not unusual to find geographic barriers placed by many manufacturers because they don’t want to (or cannot) support their product outside the USA. But that doesn’t stop Australian consumers wanting one! That’s where companies such as Big Apple Buddy, a New York City-based “shopping concierge”, comes in. You simply tell Big Apple Buddy what you want to buy and they search for it – then send it direct to your door via Fedex, UPS or DHL, meaning delivery to Australia can take as little as one week. There’s a minimum $US50 per order service fee to take into account the legwork required. They tell you the charges (including freight) up front, before proceeding to purchase the goods you require.
