Ascii Heart Necklace

ASCII heart necklace by Becky Stern

Okay, I was initially impressed by Becky Stern because I loved this ASCII Heart necklace she made in her metalworking class.  Then I saw the LilyPad Arduino Blinking Bike Bag Patch tutorial she submitted to Instructables.  What I especially like about this project is that she’s using the ability to illuminate clothing for a purpose.  She’s someone to watch.

Kyoto Box defines ingenious

The Kyoto Box

I would define an ingenious device as one that solves a complex problem with a cleverly simple and inexpensive (and therefore accessible) solution. The Kyoto Box is a solar-powered oven made from cardboard — yes, cardboard.

This device recently won the FT Climate Change Challenge, which is a Brit competition to find the most innovative solution to the effects of climate change. The box’s creator, Jon Bøhmer, is a Norwegian who lives in Kenya.

So what makes this box so great and so “green”? It can be used to purify drinking water (did you know that water pasteurizes at a mere 65 degrees?) and it decreases the need for firewood. In the developing world, these are big issues.

Kyoto Energy,  Bøhmer’s company, has a few other really cool inventions, including the Kyoto Bag, which heats and cleans water and can be used as a shower, and my favorite: Kyoto Mosaic — plastic mirrors that can concentrate the Sun up to 500 times.

Our robot-ruled future (it’s not as scary as you think)

Most people have an idea of what a robot should do: it should serve us –- cart snacks over to the couch, rub our feet, make the bed. Kind of like a slave, which is when all the worries about robot consciousness crop up. Uh oh!

But the technology coming out of robotics allows your camera to self-focus and gets rid of pink-eye. It’s also allowing for better medical treatment with regard to, for example, prostate surgery (just went to a lecture on this last night, with video).

In fact, maybe someday –- and this is the most fascinating robot-related research I’ve read about recently — you’ll be able to pull a mobile phone out of your pocket and morph it into a laptop. Seriously. I’m shivering over here.

Periodic Table of Videos makes elements fun – especially K

Periodic Table of Videos

My 11th-grade chemistry teacher was five feet tall with four-foot boobs and wore lab coats over her minidresses (no, this wasn’t the ’60s) so all you saw were her spindly toothpick legs on top of platform shoes.  Sounds cool, doesn’t she?

But she wasn’t cool at all.  In fact, she was so crabby and had such an instant dislike to me that I despised chemistry class, including all the experiments that I otherwise would have loved.  (At least my Physics teacher was kind of nice.)  But now I can re-learn fun facts about all the elements with The Periodic Table of Videos.

It’s such a blast!  Just click on an element and discover some of its most interesting qualities.  Right now K (potassium) is my favorite.  It’s highly reactive and according to Professor Martyn Poliakoff (the vid host), one of his colleagues describes it as evil — wha-ha-ha.  Check it out:
