If you know someone who doesn’t respect electricity have them watch the above video from Fast MHz. The best part of the video is around the 21 second mark when a Dell power supply is zapped with 16kj of electricity. It looks like the power supply may have permanent damage from the experiment! The subwoofer shown at the 56 second mark has a remarkably long throw, must be a very expensive speaker. Or maybe the speaker was over voltaged.

Ever wonder what is in one of those heating pads? Well you’re in luck, I have one here that stopped working. Of course I didn’t chuck it in the garbage, I took it apart and see what made it tick. Overall it is exactly what I expected, a few thermal cut out devices, one had obviously over heated and opened the circuit. It must have been hot for awhile before it disconnected the power though since the heat shrink and the plastic surrounding the area was heavily melted.

The wire was the most interesting thing of the disassemble, it has a very tough outer insulation and an internal metal heating element that is spiraled around a central core. I kept a some of the wire and might make some battery operated socks from it. Since it’s just a resistive heating element if I take a chunk that is about 1/12th the length of the original I should be able to power it from a FUSED battery pack. For now it’s another item in my ever growing junk box.

Have a look at the image gallery after the jump.

Fast MHz has unleashed some serious energy against a beer bottle. The results are dangerously interesting. Melting beer bottles isn’t anything new around here though, remember when Bill Beaty melted one in a microwave?

Thanks to EFO for sponsoring the contest this week. They will be providing a Black Wireless Handheld Keyboard and Touchpad Mouse to the winner. They saw the article that we had done earlier today about their product and wanted to provide one to a Hacked Gadgets reader. Nice thing we have the perfect mechanism for selecting that reader, our weekly contest! The remote comes with a wireless USB dongle that has a range of around 32 feet. The system seems to work with anything from gaming systems like the Playstation 3, XBox 360 and the Wii to computer platforms like Mac, PC and Linux. The winner will get a black one but the control is also available in white. I like the fact that the size of the keyboard looks like a Blackberry cell phone, but if you like pecking text on your normal phone I also found this cute computer remote what allows you to type just like you do on a normal cell phone.

This contest will run for one week (December 5 – December 11, 2009) . Ending time is based on central standard time. To enter, identify the item pictured above and give an example of what can be done with it.

Please do not give the answer in the comments.

Below is the prize.

Thanks to the book publisher for sending us a copy of Mini Weapons of Mass Destruction for review. It brings back memories of high school hijinx. This book by John Austin is packed with over 200 pages of fun weapon build guides. It is actually meant for office warriors but I am sure a home office will work just as well. In the first section of a project there is a list of items you need to raid the office supply cabinet for. Common items needed are tape, paperclips, pencils, pens, binder clips, popsicle sticks and rubber bands. You are then told what tools are needed to make the project, most things would be at hand in the common office. Finally there are well illustrated pictures that show the steps needed to build the project. There are lots of launching projects where you can share the fun with your office mates. Flip to the end of the book to find targets that can be photocopied to hang up and keep track of who is the best office warrior!

Where was this product about 4 years ago when I was running a home theater PC? I was using a wireless keyboard that got the job done. Only problem is the range was not great since it was meant for desktop computing, the keyboard was full size and has a stand alone wireless mouse. I found it overkill since I was never typing anything more than a few words here and there. It was also a pain to store in the coffee table.

EFO has a product that would have been ideal for my setup, it is a tiny device that has a touch pad mouse on the top and a small keyboard on the bottom. The keyboard reminds me of the ones that you would see on a Blackberry. This unit comes with a wireless USB dongle that has a range of around 32 feet, that is good enough for my living room and then some. The system seems to work with anything from gaming systems like the Playstation 3, XBox 360 and the Wii to computer platforms like Mac, PC and Linux.

The Wireless Handheld Keyboard and Touchpad Mouse comes in Black which might match your black PC and remotes on your table, and White which would go well with the white Mac systems.

This should make a great holiday gift since the current price is only $40.00 with a shipping cost of $5.00.
