I shouldn't be doing this!

I just found a photo of me from school when I was somewhere between 15 & 16 years old:

 

 

 

 

and comparing that to a photo of me that is much more recent:

 

 

 

 

has made me realise that I really need to turn off the computer and catch up on some much-needed beauty sleep!

Steampunk SegwayPosted in DIY by Conner Flynn on April 17th, 2009

The Steampunk Segway aka Legway, has some trouble making turns, according to the creator, but if you can’t afford a real Segway, this is a cheap DIY alternative. Of course you’ll have to provide all of the power yourself. At least that makes it eco-friendly.

If you want to try your hand at making one, head over to Instructables and make your own Legway. Then prepare to feel the burn. Before you know it, you’ll be saving up for the real deal. Because pedal power is for the birds.

This was going around at work today. It puts a whole new angle on demonstrations of how sorting algorithms work.

Clipped from: Sorting algorithms as dances:

 

Take one Central European folk dancing team, a small folk band and an added overlay showing array locations and get them to dance the [sorting] algorithms in time to “appropriate” folk music…

Go see the whole thing – it’s great!

MIT’s artificial leaf is ten times more efficient than the real thing (Wired UK).

Artificial photosynthesising leaf

MIT professor Daniel Nocera claims to have created an advanced solar cell which uses sunlight to split water into its two core components, oxygen and hydrogen.

With a single gallon of water, Nocera says, the chip could produce enough electricity to power a house in a developing country for an entire day. Provide every house on the planet with an artificial leaf and we could satisfy our 14 terrawatt need with just one gallon of water a day.
