From The Tips Box: 3D Eye Pain, Finicky Spacebars, And Remember The Milk

Readers offer their best tips for watching 3-D movies in 2-D, fixing weak spacebars, and making the Remember the Milk cow more sympathetic.

About the Tips Box: Every day we receive boatloads of great reader tips in our inbox, but for various reasons—maybe they're a bit too niche, maybe we couldn't find a good way to present it, or maybe we just couldn't fit it in—the tip didn't make the front page.

Watch 3-D Movies in 2-D With an Extra Pair of Glasses

Derilium shows us how to relieve eye pain from 3-D movies:

3-D is becoming more and more popular, and after a long time, I usually get kind of dizzy. So what I do when I go to the theatres is I use the regular 3-D glasses, and then also carry around my own pair of "2-D glasses"

To make my 2-D glasses, I just basically got 2 pairs of 3-D glasses, and switched the left lens on one with the right lens on the other. Then, I end up with 2 pairs of 2-D glasses.

If you're curious for how this works is that the lens on the left filters out the left picture. The lens on the right filters out the right picture. So when I put both of the left lenses together, I end up with just seeing the left picture. On my other pair of 2D glasses, I end up seeing just the right picture.

This allows me to watch a 3D movie in 2D when I get dizzy from too much 3D. So far, wearing these 2D glasses haven't been giving me headaches.

Make Your Spacebar More Responsive From the Sides

Flickr user zomBdog shows us how to fix finicky spacebars:

I was having a problem with my new and expensive Logtitech Illuminated Keyboard. The Spacebar wouldn't register if I hit it softly, which is the way that I generally type.

Searching around the internet, I see that a few others have had this same problem with this keyboard. I'm posting this fix for those people.

I recommend that you first contact Logitech to see if you're covered under warranty. I wasn't, as I bought refurbished from an eBay vendor (and the serial number had been blacked out).

If you've never pulled a key off of a keyboard before, here's a vid you can watch for instructions.

On this keyboard, pull the spacebar off by pulling up and back from its top edge. I used both hands to minimize torque. It's clipped to key scissors on both ends and in the middle. Refer to the image for the explanation of my fix.

All keyboards are a little different, so your mileage may vary, but it did wonders for mine.

Make the Remember the Milk Cow React to Your Task List

Dale Lane blogs about his Remember the Milk greasemonkey script:

I am a big fan of Remember The Milk (RTM), the online to-do list manager. It's one of the few sites (like Flickr) that I'm happy to pay for. For some reason, the logo for RTM is a cow's face. Which means that I get a cow staring at me when I'm deciding what I need to do next.

I had a random thought this evening – that the cow should really look more sympathetic when my task list is so full. Because he's really quite heartless, even when I'm manically busy. And once I had the idea, I kinda had to give it a quick try. (And I wonder why I'm busy…)

So I've knocked up a quick Greasemonkey script – which should work with Firefox with the Greasemonkey add-on, or with Google Chrome. If you have no tasks due today in a list, the RTM cow smiles. If you have more than a few tasks due today, the RTM cow is sad. . . and so on.

Okay, so this is all a little silly. The number of tasks doesn't really mean a huge amount, and my choice of numbers was a little arbitrary. But it was distracting for a bit. And I do like the idea of a to-do list UI that panics with you when you get busy.

Flip Worn Vacuum Belts Inside Out for a Quick Fix

MkFly shares a quick way to fix a worn out vacuum cleaner belt:

If the belt on your vacuum cleaner is getting worn out, try flipping it inside out.

I just started vacuuming when I smelled burning rubber and then saw some smoke (uh oh). Opener 'er up and saw that the in-side of the belt was worn down to a very smooth shine, so there was no grip.

It was otherwise still usable — it wasn't loose and the rubber was still plenty thick.

I don't know how long it will last, but it works wonderful for the moment. At least it saved me a special trip to pick up a new one.
