Printed Optics: 3D Printing of Embedded Optical Elements
for Interactive Devices, a paper from Disney researchers in Pittsburgh, details a set of toymaking techniques involving 3D printers. Some of them (like "a bug-like figure with glowing eyes that display different graphics") are intriguing in the extreme. I like the way they're thinking about 3D printed micro-channels as a means of moving light around within a solid toy. Here's the BBC's summary:
One application involved the creation of air pockets in the shape of thin hollow tubes of various lengths which were arranged to resemble the shape of a cartoon heart inside an animal-shaped figurine.
When illuminated from below using a light emitting-diode (LED) the tubes looked as if lots of tiny lights had been built into the toy and programmed to shine in sequence to resemble a beating heart.
Another example involved creating "light pipes" as a 3D-printed alternative to optical fibre.
The engineers said the pipes could be easily shaped to fit a toy's specific form, with joints placed at specific places allowing them to be linked to other light pipes. They said this would have been much harder to achieve with traditional fibre.

Peter Biddle writes, “I get I myself into trouble. I don’t claim that bad stuff happens to me more often than others – it’s more that I find more ways to happen to bad stuff. I actually found a way to get severe hypothermia in 105°F heat.”

Benji Edwards’s guide to preserving vintage electronics is a fascinating look into all the ways that even solid-state gear can go off in long-term storage: a lot of stuff (batteries, capacitors and even rubber) can leak viscous, electronics-destroying liquids; plastics break down in UV light; mold and corrosion eat your gear from within; spiders, crickets […]

Toaster ovens are the perfect appliance for small things like toasted sandwiches and roasted garlic (try it!), but anything more involved usually requires a full-sized conventional oven.However, despite its small size, the Wolfgang Puck Pressure Oven can handle anything from baked pastries to broiled meats. This kitchen appliance has a minimal countertop footprint, and cooks […]
