Our Sun in 3D

STEREO Sun

Another link sent to me by secret agent Greg a few days ago. Its a space mission to send two probes in an orbit around the sun that will enable us to see the surface of it in 3D. On Earth you can’t do this very well because you can only get so far apart and when your at that maximum distance you have a whole lot of distorting air between you and your object of observation. Once these satellites are in place it will allow CME (coronal mass ejections) and other particle emission events with depth. Why is this a good thing? Well it will give us a much better chance of preparing for the problems that often occur when the sun has a little ‘gas’ and we all get washed with extra radiation. That can cause communications blackouts, power failures in big cities, satellites to die. And if your living in space or just visiting (think airline crews) it can be a health hazard. I for one can’t wait until images from these guys start showing up on Astronomy Picture of the Day.

 How many times has this happened to you? Your out walking the dog and you see a bright light in the sky and its coming towards you. Next thing you know your being kicked out of the saucer on some strange planet with no idea of how to get home! Turns out they just wanted Fido, that the good news. Bad news your can’t tell the locals where you came from. Well you could if you had one of these. This little lifesaver has all the info an intergalactic traveler needs to know to get back to good ‘ol Earth.

Champagne cork parachute

ChampiChute

Umm.. Yeah. Stock up on these for the Yew Year. Or better yet, as the animated GIF is better at telling how it works  than the patent papers, build your own. Ya know, nothing says ‘I’m a geek’ louder than a parachute on a champagne cork. Come to think of it, a cork parachute and a 2 liter bottle of something fizzy (I’ll go with baking soda and acid of choice for home chemistry, vinegar) should make for some weekend fun.

DIY Nikon IR Remote Shutter Release

Nikon Remote 

If your serious about photography and own a Nikon DSLR you might want to have a look at this project. It’s simple enough, he programmed a PIC microcontroller to fire off a series of pulses to an infrared LED that will trip the shutter of a Nikon D70 (should work with other Nikon cameras too, it emulates an ML-L3 remote). It’s a clever project, and easy one too.
