Too kewl...!!! Love the subwoofer.Finally I can see if all of my 11.1 surround speakers are actually hooked up in phase.Right on.
Making a Powerful Generator From a Blender Motor DIY
Awesome! Very inspirational and thought-provoking idea. I did some long-exposure experiments using different light sources (cyalume sticks, laser pointers, UV LEDs) hanging from the ceiling of a light tight room by an unwinding rubber band - this would be an interesting variation, especially shooting from the floor up.Might also be interesting to set the camera for "Rear Curtain Flash," pre-flash a dark scene with a weak strobe, and THEN turn the interval disks on while the camera finishes the rest of it's exposure.Cool stuff, big thumbs up.
Interval Exposure Light Painting
I second the motion of using "copper braid solder-wick." The stuff is pretty olde school and many people don't know what it is anymore, but it works well (especially the wider, thicker stuff) for sopping up the solder off the board before you pull the components using any heat source - and to me (being too cheap to have a temperature-regulated soldering station) it's indispensable for everyday soldering, getting into places a solder-sucker can't. It's impregnated with rosin to make the old solder flow better and "wick up" onto the copper braid by capillary action. Comes in varying widths and lasts a long time.

Interesting stuff jrbums - you can get a similar still-image effect by moving something along the glass of a flatbed scanner as the scan bar moves along - maybe you could interface it with your video processing:
Good job, rpalak - these 3-D printers are amazing things. I'd like to see what you could do with taking your design and turning the bearings 90 degrees in respect to the composite - not sure how you'd mount them, but you'd have one of those sort of "creeper" things that you put under something like table legs to be able to spin it around inside a small space... just a thought.Have fun - keep on building and learning.
When I worked in the photo industry we used to find something that was the same size as bearing's the outer race, but hollow, like a socket or a pipe end, put the thing the bearing was being installed into on a flat piece of wood, and push the bearing in using the socket lined up with the bearing's outer edge with as little force as needed - by hand or by tapping the socket with a nylon-tipped hammer. Keeping the insertion force on the outer bearing race protects the ball bearings and inner race from forces from the sides (like the hammer blow) that they aren't designed to handle.Also, if the bearing has a dust cover, be extra careful not to mash it down as it will cause drag and not keep the dust out and the lube in...
