It seems like some terrorists have made their DIY Hand Grenade Mouse.  The greatest part is that it doesn’t blow up.

If you are looking into Pyramid-related businesses (of course, we think all businesses are somewhat a pyramid-scheme), here’s a great article on how pyramids are actually built.

The first theory is that a ramp was built on one side of the pyramid and as the pyramid grew, the ramp was raised so that throughout the construction, blocks could be moved right up to the top. If the ramp were too steep, the men hauling the blocks would not be able to drag them up. An 8-percent slope is about the maximum possible, and this is the problem with the single ramp theory. With such a gentle incline, the ramp would have to be approximately one mile long to reach the top of the pyramid. But there is neither room for such a long ramp on the Giza Plateau, nor evidence of such a massive construction. Also, a mile-long ramp would have had as great a volume as the pyramid itself, virtually doubling the man-hours needed to build the pyramid. Because the straight ramp theory just doesn’t work, several pyramid experts have opted for a modified ramp theory.

Here’s a short little camera hack for those of you having trouble with re-charging the flash by adding an external battery.  It might be a hack but it will work if you are shooting photos in long sessions.

If you’ve been shooting with a flash for a while, I’m sure you had some battery problem or another at least once. Like when one of four batteries goes bad and quickly discharges the other three. Or when it’s cold and the batteries don’t hold their charge so well anymore. Wouldn’t it be nice if you could have a more reliable source of power? One that virtually lasts for ever (well, not forever, but for a darn long time).

Here’s an incredible speaker hack that involves a styrofoam plate in the making of a hi-fidelity speaker.

As you can see on the picture, I did use a foam plate. I tried other materials and I found the best quality of the sound is produced by a lightweight material but strong enough to avoid excessive vibration. Paper plates are too soft, plastic disposable plates produces excessive vibration.

Here’s a guy who managed to come up with an iPhone stand out of paper clips.  He’s even providing printable sketch sheet for those of you who want to make one.

It looks pretty simple, brilliant idea.  They could sell these with different colors of paint or somethin’

Get the template here. Print it out with your favorite PDF reader. Be sure not to stretch the document. If you have a ruler, do a reality check to make sure the document didn’t get resized when printed.  When the paper clip is straightened out, it should be the same length as the grey line in the template.  A pair of pliers will make your job a lot easier.

Here’s a great way to re-use cooking oil in a DIY homemade diesel engine to power up your garden lights.

“I have built a “off the Grid” home generator using a 1950’s Coventry Victor one cylinder diesel generator, I can run this on diesel or a diesel and used cooking oil mixture and have it attached to a large battery via a 40amp car alternator which supplies my garden lighting and via an inverter for 600 watts of home power and lighting. The waste heat is used to keep my garage warm as well.

Did you just happen to buy a giant fish tank for your shark that you caught the other day?  Well, if you want to put that fish tank by your bed, you will need to make a fish tank stand and here’s how to make one.

I don’t have any production pictures, but it should you show the general idea on how to assemble a very sturdy stand. It’s pretty simple to build, because it kind of squares itself.

I got the idea off of another member on here. It’s also the same design as my 120 and 220.
