Solving everyday niggly bits with 3D Printing

I don’t know about you, but I am one to get irritated with stuff that hangs out in the wrong places. A good example is the chest strap of the computer backpack: I never use it, but I don’t want to cut it off either and harm company property. Instead, I made a quick mesh in Blender and printed it out on the Minifactory, with the net result of straps no longer hanging around causing me to lose hair even further.

Here’s the starting situation:

Fooling people with radiation protection

I happened to see an advertisement for a “chip” that is intended to minimize the radiation from your cell phone, thus lessening the bad effect of radiation on your brain. The price for this device is 25 euros. I contacted the importer of the product to get more information on how it works, what its effects are, and how it is to be used.

The importer was very helpful in getting me three sample chips, but their information on how this device is supposed to work was limited in the extreme. They claim also on the package that the chip “provides protection for over 99.95% of cell phone radiation”. When I pointed out to them that the sole function of the mobile phone is to maintain a radio link between itself and the base station, and that if you decrease that radio link’s radiation by that much, you have no contact at all, they said that “they use the device and it works.” At this point I became quite irritated.

Let’s have a look at the claims.  (more…)
