Taxan KG-PS125X Wireless DLP Projector
For every indispensable technological development, there are hundreds that never make it off the drawing board. Some barmy inventors even go so far as patenting their crackpot ideas – as a quick browse of the archive at patentlysilly.com, and a dig into past episodes of Dragons' Den will reveal.
Cordless skipping ropes, sails for bicycles, a device for cooking the perfect hard boiled egg – the list is endless. Even Wi-Fi technology, which has been one of the technological success stories of recent years, has the odd use thought up for it that doesn't seem entirely appropriate.
Take wireless projection. Now this is something I always thought would get the funding thumbs-down from Peter Jones, Theo Paphitis and co. Reviews I have written in the past have convinced me that it just isn't worth the hassle of not carrying a VGA cable around – after all, they don't weigh very much, you've no worries about not being able to display video clips and they're never likely to let you down in the middle of an important sales pitch.
But the Taxan KG-PS125X may just have changed my mind. Setup is a bit involved as it always is with wireless kit, and entering network keys via the remote control is a pain. But once you've installed the software on your laptop and plugged the tiny SD wireless adaptor into the slot on the rear of the projector, the wireless function works mercifully easily. The projected image is responsive, tracking the movement of your cursor reasonably swiftly, while even movies play back, albeit a little jerkily.
Connection via both ad hoc and infrastructure networking is simple – an important consideration for road warriors who often find themselves in situations where gaining access to the local office wireless router just isn't possible. And for situations where the projector is permanently installed you can even set the software up to display multiple sources on a split screen. Up to four machines can be connected at once.
Even if you can't be bothered with the laptop, wireless or otherwise, this projector may have the answer. In addition to the SD expansion slot, there's a USB socket on the right hand side, which allows you to plug in a thumb drive. It's a little disappointing that the projector only displays jpeg files and not PowerPoint files, but it's certainly a handy extra.
