DIY pillbox laser projector

DIY pillbox laser projector

What do you get when you combine a laser pointer, pillbox, and an Arduino? If you’re maker Raul Aguaviva, you’ll get an awesome DIY laser projector, of course.

Collapsing “swoon” chair

Collapsing “swoon” chair

It’s a full-size chair version of one of those little wooden toys with segmented legs that collapses when you release the internal tension. I’ve heard them called “swoon toys.” This furniture-scale version called Lazy Chair, by UK designers Fresh West, stands back up rather more slowly than the toys; it takes about 45 seconds in the video above. There’s also a click-to-collapse Flash version at the designer’s website. [via NOTCOT]

I don’t know how long they’ve been available, but Timothy J. Silverman’s lovely photo (uppermost) just alerted me to the existence of these dual-reading dial calipers that simultaneously report inches and meters on the main scale and the dial. I do remember wanting such an instrument a couple of years ago and Googling around trying to find one with no success. The version pictured immediately above (and, I think, in Timothy’s photo) is this Chinese model imported by TFT Tools, but many other models are available.
