First Impressions GoPro Helmet Hero HD

One of the daily deals site offered the GoPro Helmet Hero HD for $135, and at that price I jumped on it in the hopes that I might be able to replicate the results of my touring videos locally, without having to carry a stoker up mountains (or deal with a stokers sway as she manhandles the camera at speed!).

At that price, the camera can double as a HD camera as well, for general use as well as if my brothers or friends want to borrow it for skiing.

The device comes with the camera, a waterproof case (with both a waterproof backing and a non-waterproof backing), several adhesive mounts for attaching it to a motor-vehicle, as well as a helmet mount. Sadly enough, the device as is does not come with a scuba unit, though a scuba case can be bought separately through eye of mine for about $100.

The camera comes with a few modes, 720p, 960p, and 1080p. The default is the 960p, which is a weird mode which produces a square picture. The reason for this is that on a bike you might look up and down often and it could be useful to get more picture of road. Having tried it once (see sample video), Im likely to stick with 1080p.

On the helmet, the camera does weigh your head down more. Im not sure I would want to carry it up a major mountain pass on my head, though sticking it into your saddlebag (or jersey pocket) and mounting it for the descents seems like something eminently doable. (Uphill, I have no issues with manipulating a Canon S100.

The output of the video is huge. For 1.5 hours, itll use up 8GB, so at least a 16GB card would be recommended for any kind of extended use. The battery will run out in 2.5 hours, so getting more than 16GB would be pretty pointless unless you have a spare battery. As for the lens quality, you can see it generates a lot of flare when pointed into the sun, so I would make a note of that. This is pretty bad, because cyclists dont usually have control over the flare or not. Note that the camera is designed for what I call "point and pray". Since theres no display for the image youre getting, and the cameras mounted on your helmet, you just cant possibly know what youre shooting until you get home.

On an unsupported tour, Im not sure I would want to have this on my head or in my saddlebag. It weighs only 213 grams (without the charger), but since it uses up video pretty quickly, youd either have to carry a stack of SD cards, or youd have to carry some sort of additional storage, which would be even more weight. On a supported tour, however, such as the first half of our tour of the alps, I would consider it eminently usable. I am now extremely curious to see if I can get Pardo or some other fast descender to stick it on his helmet and take it down Page Mill Road or Highway 9.

For editing the video, unlike indoor videos, where lighting frequently demands color correction (meaning you pretty much need Adobe Premiere Elements or some other such software), outdoor videos dont need much color correction, and all the editing can be done with say, Windows Live Movie Maker, which is what I used for the above sample. The output will likely be huge, but with storage essentially free on YouTube, theres no reason not to store your video there and delete it from your hard drive afterwards.

Would I recommend this? I hesitate. First of all, video editing is much tougher than photo editing. Its not clear that I want to do it, or for that matter anyone else. Secondly, Ive been very happy with my compact camera photos, and Im not sure if video would help. On the other hand, I want to attach it to some of my friends helmets so I can see how they descend, or get their comments on my descents as well, so in that sense its a useful tool.

Ironically, the one place that the HD Hero would be most useful is actually for Scuba. The 2.5 hour battery life is just right for a 2-tank dive, and the fact that the Scuba case comes with a wrist attachment means that it wont get in the way, unlike the Canon underwater housing Ive been using. Neutral buoyancy would also be a non-issue since it would be attached to you, and the case has essentially no air, unlike the Canon cases. Ill probably give it a shot and see. In the mean time, I see no reason to regret the decision at the price I got it for.

First Impressions Dell Venue 8 Pro

I gave my wife a Dell Venue 8 Pro for her birthday. Last year, she got a Nexus 10, but she found that the 10" form factor led to it not getting used much, and Bowen ended up being the primary user of the device instead. As a result, she asked for a smaller device. While Ive been pleased with the Nexus 7, all the indications are that the latest Intel Bay Trail processors run circles around their ARM equivalents, so I took a leap of faith and bought the Dell when it became available for $230. If you shop around on Black Friday Im sure you can find similar deals for this device.

The best thing about the Dell is that its a Windows box.  That means, for instance, that I can back it up using the Windows Home Server that I use for backing up other PCs. This is a great feature, since the default Nexus/Google tablet backup doesnt seem to back up as much as it ought to. (Switching devices, for instance, usually means a massive reinstall of Amazon stuff)

Unlike Google, Dell doesnt suffer from as much Apple envy. As a result we get a microSD card slot. What this means is that even though I bought a 32GB device, an additional 32GB costs only $18, with the prospect of very cheap upgrades to 64GB and 128GB storage options in the future. This type of future proofing means that the additional $5 premium over the latest generation Nexus 7 is well worth it.

On top of that, the Dell device comes with a full license of Microsoft Office, and can run any of the applications that a regular Windows machine can. That means the contortions I used to get the Nexus 7 into a partially decent photo-editing tool are obsolete: I can just run Lightroom! Or Picasa. None of those have Android equivalents, and it truly is amazing to have them available in this form factor.

The device is fast! After using it as a web-browser during Black Friday to do some online shopping, the Nexus 7 feels slow. What this means is that while buying from Amazon is straightforward on the Nexus 7, any other site (such as Newegg) is agonizing. The Dell, however, feels just like my desktop. Everything behaves like it should, and pages load fast and snappily.

Whats more, Windows 8.1 really does make use of all the power of the device. For instance, I wife discovered she could run two "metro" apps side by side. Thats a power-user feature, but she found out about it quite naturally by simply playing with the device. And of course, Windows has had multi-user support for ages, so everything works like you expect. For instance, installing Chrome for one user automatically installs it for all  users as long as you use administrator privileges to do so.

There are cons to the device: Windows 8.1 is not quite fully adapted to the world of touch devices. So for instance, at times, the on-screen keyboard will block the input field that youre entering into. Thats annoying. Unlocking requires typing in a password instead of using gestures or a pin. Thats potentially a security hole if you use it on a plane and share the same password as on your regular desktop, which Microsoft encourages because youre supposed to login using your hotmail account.

At 1280x800, the Venue 8 Pro has pretty much the same resolution as last years Nexus 7, instead of the new 1920x1200 that the Nexus 7 spots. The reality though is that if you need to pop to the desktop for any amount of time, the lower resolution means your fingers arent as fat. So thats not as big an issue as you might imagine.

And of course, theres not the rich ecosystem of "apps" on the Windows 8 store. But who cares? Since youre running full Windows with a real web-browser, applications like Amazon Instant Video which arent available on the Google Play store can simply be run on the device like a native PC. Anybody who faults this device for the lack of apps simply doesnt understand that its a real PC, not a tablet.

All in all, this device is the tablet that Microsoft should have launched last year, instead of foisting Surface RT on us. Its as cheap as an Android tablet, but has much much more functionality. Highly recommended.
