With the introduction of LG’s Dual Play “technology”, two players playing a splitscreen game, can now each enjoy playing with a full screen view for each player at the same time. Sony has something similar called SimulView for active 3D TV’s.
This sounds very high-tech and maybe even confusing,… but it’s not. It’s actually the simple [ab]use of existing 3D technology of your 3D TV in a smart way.
In this article we will show you what Dual Play does and how it works, but also … how to use it with older split-screen games that do not claim to be Dual Play compatible. The trick works with ANY split-screen capable game, on ANY passive 3D TV. Even your old original XBox or PlayStation can do this … as long as the game supports split screen playing for 2 players.
Active 3D TV’s might work as well, but you might have a harder time finding suitable glasses.

To watch a 3D Movie, you’d need a 3D TV or a computer with 3D capable video-card and/or 3D capable monitor, and not everybody has one of those.
With a few simple tricks however, modern 3D movies can be viewed on a regular TV or computer sans 3D capable display.
To maintain the 3D effect, or better said the depth perception, the good old red/blue glasses will be used (Anaglyph).
This trick works for Windows, MacOS X and Linux.
While writing an article on how 3D movies work, I couldn’t help thinking back about the red and blue 3D pictures from back in the day (anaglyph). They were considered pretty cool and how difficult would it be to make them yourselves? Sure, you might not want to stare at them the whole day, but cool none the less.
After figuring that out, I was started to wonder if it would be possible and how difficult it would be to create 3D pictures for 3D capable TV’s (see also: How 3D Movies work).
So in this article I’ll show you how to make a 3D picture with your own digital photo camera for either the good old red and blue 3D glasses, or for use on a 3D capable TV in full color.
After the era of regular 2D TV, the era of the red and blue glasses, and all kinds of other attempts to get 3D movies, we’ve now reached the era where most of us have a 3D capable TV at home.
It’s a fun experience to watch a 3D movie, maybe once or twice. It remains a gimmick for now and I suspect that it’s not here to stay, specially when looking at the latest developments of 3D TV without the need for special glasses, and the fact that current 3D movies are not really 3D, it’s just the illusion of depth perception …
In this article a quick intro how it works, the variations, and … how to play 3D movies on your TV with applications like XBMC.
You’ll find some info on Dual Play for computer games as well.

Most 3D printer use a heated bed to make sure printed objects stay in place (amongst others).
The principle is based on keeping the object at a certain temperature, so that temperature differences between printed layers will not cause “warping” and even pop your object loose from the bed … and as a result of that screw up your print, and in bad situations even start dragging your object all over the place. (reference)
The time it takes to heat a bed however can take a long time, and frankly, I’m not that patient. So I use a super simple and cheap trick to speed up the heating process of the heated bed. It’s pretty much free and easy to use. I assume this will work for all 3D printers that print with plastics like ABS, but I have only used it with a LeapFrog Creatr so far.
Back in the day, DVD was quite a thing. Excellent picture quality, very good sound. Light years ahead of the good old (and analog) VHS, Video 2000 and BetaMax tapes that had been around for years.
It seemed though that DVD wasn’t “good enough” anymore to meet the increasing demand for storage space, and other formats like HD-DVD and Blu-Ray emerged (around 2001).
HD-DVD lost the battle and Blu-Ray and regular DVD’s are the current “standards” (with an upcoming Ultra Blu-Ray format for even higher resolutions: Ultra HD or 4K video).
So what is the difference between Blu-Ray and DVD?
Besides the fact that anything Blu-Ray will not play in your loyal DVD player, and more expensive videos of course …
