Prosthetic eye digital camera with video




Nobody with binocular vision would consider replacing a functional natural eye with a digital camera. But Tanya Vlach's vision is monocular, after losing one of her eyes in a car accident. A matching ocular prosthesis gives the San Francisco native a normal appearance, but it's unable to provide vision -- in its current state, at least. Vlach turned to Kickstarter for donations that would allow her to install a unique, waterproof in-eye camera, theoretically capable of transmitting 720p HD video wirelessly to a mobile app, and zooming and capturing still images using a blink-activated sensor. Features also on the wish list: facial recognition, a dilating pupil that changes based on light, infrared / UV capture, and geotagging, just to name a few.

WiFi Baby 3G review : a surveillance camera ?


Obsolescence. Its avoidance is the biggest problem facing any gadget nerd. This affliction, this curse that disables so many would-be tablet and smartphone buyers, only intensifies for those of us who somehow manage to procreate. See, newbie reproducers, temporarily insane from an overblown sense of paternal concern, will pay just about anything for products promising to make their new baby healthier

Tachyon XC HD helmet camera review

When last we saw a Tachyon XC helmet cam it was clinging futilely onto the side of another, stuck together so that the footage coming from the two could be combined to create 3D -- something GoPro is now trying to do much more expensively. We weren't particularly convinced at the time, largely in part because the resolution of each of those XC cameras was only VGA. Now there's an HD model we've been given to try, and while we've happily ditched the Siamese action to go solo this time, some issues remain here that keep us from giving the new, $179.99 Tachyon XC HD our universal recommendation.

Out of the box

How do you tell a Tachyon XC from a Tachyon XC HD helmet camera? Easy: you look for the "HD" printed on the side. We're pretty sure that's the only exterior distinguishing factor between the two, at least it's all our untrained eyes could pick out. And that's not a bad thing by any means.

Sure, the XC has a chassis that's slightly chunkier and bulkier than the Contour line of cameras, but it has one major advantage: it's totally waterproof right out of the box. The rear door shuts tight with a reassuringly loud noise that damages hearing and lets you feel confident the SD memory card and dual AA battery pack inside will be kept dry. It's far more beefy than the flimsy plastic latch on top of a GoPro. The Tachyon is rated to 100 feet, but we'd guess it'll manage a lot further before its little hull goes Das Boot.

It's incredibly durable feeling, too. While we never did try throwing one out of a moving car it surely wouldn't miss a single frame of tumbling highway and sky. We did, however, fumble it into the ground more than once, cold hands lacking dexterity. It shows no sign of damage.

Controls are just as simple as before, little power and menu buttons on top, and a larger start/stop button. There's a small LCD up there that lets you see whether you're capturing video or stills and just how much memory card and battery life is left. Up front, under the lens, hides a single tiny LED. It's green when ready to go, red when filming. It's never any other color but dark.

On the slopes

We tested the Tachyon XC HD in a number of situations, but we had the most fun with it on the slopes in what is truly an epic winter if you're the sort who likes to zip-tie pieces of paper to your jacket and stand in lines at lift gates. We busted out the goggle strap mount and found some black diamonds -- and some green dots, too.

Tachyon XC HD helmet camera reviewThe first problem carries over from the older XC: a start/stop recording button that's impossible to find with gloves on -- or at least with gloves that will keep your hands warm. Even bare-handed it's difficult to find and requires a heck of a squeeze before it starts filming. The company thoughtfully includes an IR remote that you can use instead, with a single start/stop button on it. This button is much easier to find, but if it's not pointed right at the camera it doesn't work.

The temptation is to just keep tapping the button a dozen times, but since it's one button to start and stop you run the risk of turning it on and then back off again. Curiously, the camera doesn't beep when turned on with the remote, so unless you have an assistant standing by to look at your little light it's awfully hard to tell whether you're recording. Woe betide those with red-green colorblind assistants.

Tachyon XC HDThankfully ours suffered no such affliction and, recording, we headed down. The Tachyon helmet mount can only be used on the right side of a helmet, and features no padding on the inside. So, skittering over the hard-pack it has a tendency to rattle against a helmet's exterior, something which you can definitely hear in the video. Naturally this won't be a problem if you're using any of the other camera mounts. This is particularly true for the picatinny rail mount for rifles, though we're thinking you'll have some other audio artifacts to deal with in that case.

Overall audio quality lacks definition, but that's thanks in large part to the waterproof nature of the device. It doesn't suffer the constant whooshing of the Contour, but as you can see in the video above it doesn't do much for capturing the spoken word.

And overall video quality is on the poor side compared to the other 720p models. We brought a Contour model along to compare. That ($100 more expensive) camera shoots at 1080p natively, but dropped to record in 720p you can still see the difference in clarity. The Tachyon XC HD just looks slightly blurry, lacking detail. It did, however, deliver a brighter picture on the cloudy day we tested.


Click for higher res
For a battery life test we topped up a set of AA Eneloops on the charger and then pointed the camera out the window. A little over 3.5 hours later the thing recorded its last moments of footage, batteries dead. That's a quite healthy duration and, since it runs on standard batteries, adding more juice in the field is certainly easy enough.

Wrap-up
Ultimately the story here is much the same as it was with the original Tachyon XC, only this time we're talking about many more pixels. Image quality is definitely far improved with the HD model but still doesn't compare to other 720p offerings like the (now departed) 720p Contour model, nor the $180 GoPro 960. But, at $180, it is among the most affordable HD helmet cameras, on par with GoPro's cheapest and leaving us feeling a lot more confident about its durability.

So, good value then, or is it worth paying more for something fancier? That depends what you're going to do with it, and how nicely you're going to treat it. Are you looking for something you can get covered in mud, water, and whatever other filth comes your way without worry? Would you like to be able to hose off your helmet cam at the end of the day and then smack it against your leg a few times to dry? Do you need a camera that will shrug off a few-dozen magazines worth of practice? This is a good choice. If, however, you need a better picture quality and don't mind being a bit more gentle, you could do better elsewhere.

Olympus SZ-10 and 3D VR-330 superzooms announced alongside entry-level VG-110



What's your preference for getting up close to the action? 18x wide 28-504mm or 12.5x super-wide 24-300mm optical zoom? If it's the former then Olympus just announced its $249.99 (ships in March) SZ-10 ultra-zoomer pictured above, with 14 megapixel 1/2.3-inch CCD sensor, 3-inch LCD, TruPic III+ image processing, and Eye-Fi Card support. Otherwise, Oly's new £159.99 3D VR-330 for Europe dials back the zoom to 12.5x and and forgoes the newer image processing of the SZ-10 while boasting the same 14 megapixel sensor. Both cameras pack dual-image stabilization, 720p video capture, HDMI-out (with CEC support so that it works with your TV's existing remote control), and a dynamic "3D mode" that instructs you to pan and shoot a second image that will be combined into a .MPO file suitable for playback on a 3D display. The VR-330 is also available without the 3D mode as the $199.99 VR-320 which ships Stateside in February. Bringing up the rear is an entry-level $89.99 VG-110 with 12 megapixel sensor, 2.7-inch LCD, 4x zoom, and VGA video. Look for it sometime later this month.

Canon trots out Canon Rebel T3 and Rebel T3i DSLR cameras

Not looking for a new PowerShot? How's about a new DSLR? Canon has just rolled out a new entry-level Rebel and a new flagship Rebel this evening, with the T3 (1100D) and T3i (600D) offering mild updates over their predecessors. The EOS Rebel T3 will ship at the end of March with a EF-S 18-55mm f/3.5-5.6 II zoom lens for $599.99, offering up a 12.2 megapixel CMOS sensor, DIGIC 4 Imaging processor, nine-point autofocus system and a 63-zone dual-layer metering system. You'll need to provide your own SD, SDHC or SDXC card, but unlike entry-level bodies of the past, this guy will capture full-motion video at 1280 x 720. There's an ISO range of 100 to 6,400, a pop-up flash and a newfangled Basic+ non-technical interface that should help beginners grow accustomed to more technical aspects of photography without the steep learning curve.

Stepping up, there's the new T3i, which boasts an 18 megapixel CMOS sensor, an ISO range of 100 to 6,400, support for SD / SDHC / SDXC cards, DIGIC 4 Imaging processor, pop-up flash, integrated Speedlite settings (to go along with a few new Speedlite flashes also introduced today) and a tilt / swivel LCD monitor. It'll ship at the start of March for $799.99 (body only), or $899.99 bundled with a EF-S 18-55mm f/3.5-5.6 IS II zoom lens. Hit the source links below for the devilish details, not to mention information on two new telephoto lenses (the EF 500mm F/4L IS II USM and EF 600mm F/4L IS II USM).
