The Nvidia 3D Vision Shutter Glasses Get an Update and Price Slash

March 15th, 2011 · 14 Comments · GeForce 3D Vision

A bit over 2 years after the initial announcement, the 3D Vision shutter glasses from Nvidia finally get a small update and a price decrease for both the full kit including the 3D IR emitter and for the additional pairs of glasses only. The updated version of the 3D Vision wireless glasses kit should now have a price of $149 (US), $50 less than the original price. And the new glasses should provide 50 percent longer battery life from a single charge, meaning about 60 hours compared with 40 hours before.The new price of the extra wireless glasses is $119, so now is should be easier and more affordable to share the 3D experience with your friends.

There is no official information regarding any other changes in the glasses themselves, besides the use of a bigger capacity battery that can provide you with an up to 20 hours more on a single charge. With the older batteries being 50 mAh, 3.7V we can safely assume that the new glasses will come with a slightly bigger 75 mAh batteries, although that is not yet confirmed. I’ll try to find more information if there are any other improvements in the new version of the glasses as well as how you will be able to differentiate the older from the newer version, so stay tuned for more information about that.

Update: It seems that the new 3D Vision kits will have s smaller package as the photo above also hints, and the European version is also getting the 3-pin mini-DIN VESA Stereo cable in the package as previously it was only available for the North American units. And other than the battery upgrade there are no significant changes in the shutter glasses…

Upgrading the Rechargeable Battery of the 3D Vision Shutter Glasses

August 6th, 2010 · 27 Comments · GeForce 3D Vision

The Nvidia 3D Vision active shutter glasses use a rechargeable lithium-ion battery that normally should be able to provide you with up to 40 hours of use per single full charge which is nice, but it could’ve been easily even better. The reason for that being that Nvidia is using a 3.7V 50 mAh battery that is located on the right side of the glasses and as you can clearly see from the picture above of the battery, there is quite a lot of free space left around the battery. So there could be a more powerful battery instead of the 50 mAh battery providing some more hours of use per single charge – these is the space and it probably won’t increase the cost much anyway…

But since I’ve had a spare 3.7V 120 mAh lithium-ion rechargeable battery lying around that I was not using, I’ve decided to try replacing the standard battery of the glasses with that one. That of course requires a little soldering and desoldering, but the good news is that the 120 mAh battery fits just fine in the free space that is available for the battery. This means that Nvidia could easily use a 100/120 mAh battery instead of the 50 mAh one they’ve decided to go for and doubling the capacity of the battery should pretty much also double the time you get to use the glasses with a single charge.

After replacing and recharging the new battery everything was functioning perfectly fine, I’ve already been using the glasses for a few hours, but I’ll need quite some time in order to check the full time they will provide with a single charge. However theoretically speaking with a 120 mAh capacity the battery should be able to offer increased time of use from the normal 40 hours to around 100 hours which should be much better – charging less often and longer battery life.

And here I’m thinking about the 20 hours expected with a single charge by the 3D Vision Pro glasses, if they are still using the 50 mAh battery then it gets half the working time because of the RF two-way communication. So with a 120 mAh battery the operating time could’ve been increased to lets say 50 hours which should be much better. But we’ll have to wait a bit more in order to be able to confirm that. And here now I’m thinking about all those first generation of active shutter glasses sold for the new 3D HDTVs that come mostly with lithium batteries offering just single use and not being rechargeable, but at the same time not being cheaper than the 3D Vision glasses either. Lets see how brands like Panasonic, Samsung and Sony will deal with offering rechargeable active shutter glasses for their 3D-ready television sets and frankly I hate it when I want to use something and the battery suddenly dies and needs to be replaced, especially if you don’t have a replacement handy.
