Soldering tutorial

Hey there

When first starting out on electronics, I found soldering really frustrating, mainly because I was missing a few good tips and tricks that make it a breeze! So I've just finished off a video tutorial, and thought I'd post it here in case anyone finds it helpful :)

laser distance measuring

I've been pondering building a musical instrument with multiple 'strings' that are actually a set of distance measuring devices set up in a line. However in order to avoid the strings interfering with each other it occured to be lasers might be the best approach. Unfortunately pre-constructed laser range finders are pricey. Has anyone got any experience putting these together from smaller components (i.e. a laser light plus a sensor).

help with 3d image reconstruction (from stereo or multiple images)

Does anybody have any experience with, or any good references on reconstructing a 3d scene from a stero image, or lots of images from different positions?

My use case is obviously a robot (MmBot) which has a stereo camera mounted on the front. I don't want to use a proper depth camera, as they are intrusive so I couldn't have multiple robots in the same room all seeing at once.

This is MmBot with the stereo cameras on the left, and the image she sends to the pc on the right.
