Today’s Cool Video

I really like the music in this video by Graffiti Researd Lab showing LED Throwies. Well composed!

A Throwie consists of a lithium battery, a 10mm diffused LED and a rare-earth magnet taped together.

From the Make:Blog comments. One commenter questions the environmental impact:

what do you think the ecological impact of peppering the landscape with a handful of lithium batteries is?

And another bemoans the waste of good electronics:

It seems a shame to have the still good magnet and still good LED slaved to a dead battery halfway up a wall.

Raggy! Roomba Rooba Roo!

Molly restsI wish I could have had a video camera! Molly was resting on the floor and the Roomba whirs over and bounces off her nose. She doesn’t flinch! Since her long nose is obviously new territory for the Roomba, it immediately kicks into “outline the perimeter mode” where it moves a little bit then rotates back into the barrier and repeats over and over. So here’s poor Molly trying to get a nap and this robot is noisily tracing her snout!

After about the 5th bump she nonchalantly raised her head and let it pass. If you have pets and are concerned your pet and Roomba won’t be friends, I’d put your fears to rest.
