China tightens grip on rare-earth exports

China tightens grip on rare-earth exports

Rare-earth sounds like something from a science fiction novel in search of another planet for humans to populate. Rare-earth is actually minerals and ore that are dug from the ground and refined for use in making all sorts of things in the electronics and technology world. China supplies about 95% of the rare-earth materials in the world and the nation is tightening its grip on supply of the material and using the tightening supply to drive the price of the material up.

Arduino-Based Geiger Counter

Arduino-Based Geiger Counter

Geiger counter, it's a word that most people have heard about. I'm sure everyone has seen at least one piece of media featuring the clicking box with a little dial that only tells you when you're going to die a slow painful death from radiation poisoning. It's not a very fun device. Actually, they're pretty awesome. Who doesn't want to be able to play with a gadget that can sense things that only manifest in humans as genetic decay?

Electronic Sunglasses Use Glare Shield to Block the Sun

Electronic Sunglasses Use Glare Shield to Block the Sun

Sunglasses may not be the fashion trend they used to be (that may not be a bad thing), but that's not stopping one designer from giving the sunglasses a brand new way from stopping the sun from invading your eyes. Instead of coating the entire lens of your sunglasses, designer Chris Mullin wants to be able to focus on the sun directly, and use what he calls a Glare Shield to keep the sunlight out of your eye, but without dimming everything else you're looking at, too.

In Search of Solder and a Sense of Achievement

In Search of Solder and a Sense of Achievement

Should all geeks have soldering iron burns on their hands if they want the title? Probably not; after all, another hallmark of the ideal geek is an affinity with code, making software do amazing things. They come in all shapes and sizes, then, but there's a special, envious place in my heart for those to whom resister colors are meaningful rather than decorative. I look at the sometimes-useful, sometimes-bizarre, invariably brilliant projects documented on MAKE; I look at modders and DIY tinkerers like jkkmobile, slotting HSPA modems where manufacturers never intended them to sit, and I wish I could be trusted with a soldering iron and screwdriver set to do the same.

Oh you hackers. The folks over at PSJailbreak start the week strong by announcing their positive break into PS3 firmware 3.42, 3.50, and they say any future firmware versions the peeps at Sony have to throw at them.

Batteries the Size of a Grain of Salt

Batteries the Size of a Grain of Salt

UCLA researchers are setting a Grain of Salt size goal for their new project which is to develop a tiny version of lithium-ion batteries. This is the kind of battery you'd find in your laptop, your cellphone, and the music player you've got there on your desk. Research is said to be in early stages, but may one day power miniature electronic devices ... maybe like a little robot like they had in the one movie... Transformers? No. Batteries Not Included.

M-Dress is the Little Black Dress That’s Actually a Cell Phone

For the most part, clothing should probably just remain "clothing." You know, stuff that keeps us warm, or generally just keeps us covered so we don't freak out a bunch of people walking down the sidewalk. But, that's not stopping some crafty designers from making a little black dress that's actually, and we mean this, a cell phone. That's right. You get to use a SIM card and everything.
