Wanna know what causes that 'orb' out there to glow orange? And get some useful data while doing so? (can even log the data too)
Here's an interesting, scientifically useful, simple and inexpensive to construct gadget for the techy UFOologist out there who is interested to know a little more than what may be seen in video alone....
The BOM (Bill-Of-Materials) a. sheet of stiff black paper-board (Michael's Art Supplies) b. a DVD-R CD disc (not been recorded) c. Junk VHS cartridge or electrical 'elbo'/right-angle connector d. cheap USB web-cam ($25..TigerDirect, BestBuy, Frys Electronics, etc) e. black-tape roll f. laptop with USB ports and webcam driver software g. InterNet connection h. FireFox web-browser
The program, 'Spectral-Workbench' is Java based, and runs on one's web-browser and so, it'll run on any computer platform (such as iPhone) capable of running a web-browser. Everything is 'OpenSource' and so the program is free.
In this is DIY (Do-It-Yourself) project, the most expensive item, aside from the lap-top/iPhone (etc) is the $25 webcam, everything else is cardboard, CD, plastic VHS box or a plastic (better choice) electric 'elbo' coupler....and a bit of sweat.
Original plan was engineered by the scientists at the Cern and was released into the public domain...

After watching this I'm having all kinds of DIY thoughts running through my head. ;D Here's one. What if I were to take this another step further and do the afocal method with a telescope ? I know the light source would most likely have to be fairly bright in order for the sensors to pick it up but perhaps a few mods there also,,,,,, Then, instead of a webcam, a camera would most likely work also. I've always suspected that something could be done using these dvd's because of the spectral colors they seem to emit but this confirms it and I think this is rather cool. I can see myself doing something like this on a rainy day and making something happen. I might be able to figure out the composition of those orange things using something like this,,, or possibly even a distant star with further modifications ? I've made small , simple spectral colors before with a right angle prism for the sun but one day with just the right stuff I'd like to take it a step further and build a spectrometer for further astronomical purposes. I'm sure it's going to require a bit more then this but I think it might be do able ,,,maybe. If Sir Isaac Newton could do it in the 1600's,,,then I can too ! ;D ;D ;D Thanks Plutronus !

Hi Cliff,
Yep, its a tasty one alright! What I love is the quality of the data and the potential of measuring suspected ET phenomenon, and the very likely ease of discriminating things like spectrum signatures of objects such as landing-lights from those of authentic ET mecha sighting events!
The photo I attached below gives one a screen-grab peek of the type of data actually returned (which is loggable) via the user's web-browser. This instrument is not the usual low-grade, eye-peice, dim, home-brew spectrometer one is accustomed to seeing that employs a crappy hobbyiest grade, expensive, diffraction mirror.
Re; using a still camera, if its a CCD type, I suspect that it'll likely work, but I'd asked the guys who designed it for their opinion.
And then there's the on-line real-time Spectral-Workbench program which one can access by clicking this link: spectralworkbench.org/spectra/show/1033 Move the mouse caret over the spectral graph area below the color-spectrum acquisition graph gif, be sure to click the 'toggle RGB' button, and notice in the lower left corner of the Workbench the nanometer readout. This is the kind of stuff one expects to see in a $5000 instrument.
Man this is really sexy stuff!!
Cheers
