Edo-Style clock kit build

What time is it? If you live in the North East, it’s time to shovel! Then again, maybe it’s time to stay inside and make something? I built the Gakken Edo-Style clock kit from the Maker Shed last week, so now I’ll always know the time. The kit doesn’t include English instructions, but it does […]

Rob’s laser microscope build

Rob Cruickshank built this sweet laser microscope based, at least partly, I flatter myself to presume, on my recent project. There are more pics in Rob’s Flickr set, including one of the custom screw-fitting he made to hold down the momentary switch on his laser pointer. Rob also reports that water squeezed from an aquarium filter is an excellent source of microfauna-rich samples. [Thanks, Rob!]

I get nostalgic when I move out of a home, especially if it’s one I’ve lived in awhile. Leaving a secret treasure or two, stashed here and there, seems to help me get closure. Unlike, say, dropping a note down inside the wall, a note on the back of a switch plate is likely to be found sooner or later, but not right away. I’ve included a PDF template with a tiny font that makes it easy to fit a 500-word message on the back of a standard light switch plate.

A couple of weeks ago I posted about this sweet laser stunt from Teravolt.org, and I finally got around to trying it for myself. My laser is only 10% as powerful as theirs, but I can now say with conviction: Everyone should try this.

The only tricky part is getting the laser and the hanging drop of water lined up and keeping them aligned, but this simple stand I built from hardware store odds-and-ends makes it easy. The laser and syringe snap into broom clips mounted on supermagnet bases which allow easy positional adjustments, but hold strongly enough to keep everything in alignment once you’ve got it right.
