Nice, simple 3D scanner

Here's a nice laser scanner setup. You can get respectable results with the free version and a cheap laser from a level. You can even use a shadow line for a scan, so you could probably get respectable results outside using a thin, straight stick and the sun.

The video of the thermite weld was taken about 100 yards down the track from a crossing that I pass every time to go to work. Maybe I should take a gander at that piece of track ...

Re: Sudden Zune death?

I love how the Ad system automatically posts a Zune advertisement under this post :lol:.

Perhaps if I refresh the page, the system will infer my location from my IP address and, based on the keyword "death", post advertisements for local morticians :shock: . Ha!

Re: youtube

One of Mark's recent posts listed something from "LenapeFireTurtle" as a related video. The "Lenape" part caught my eye -- so I presume that LenapeFireTurtle is the LFT in "Sebastian LFT". I didn't have time to look at all oft eh videos, but the ice pulse-jet was pretty cool! http://www.youtube.com/...

Here's an interesting idea that I saw on another forum. If you have a graphical plot, you can use GIMP to integrate curves. You can take pictures of curves, fill in portions of them and then do a pixel count. The number of pixels are an integral of the filled in region. In general, the scaling of th...

Re: Strange spooky circles

Cool! I'll need to take a peek at that film when I get home, but I'm vaguely remembering (?) that that is from Lenape Park (do I recall the name correctly?) -- near where the Little League practice field were (are?) -- on the same street as the Dairy Queen, only headed towards Sellersville ...
