I'm a mechanical engineer (and I design/build furniture with built-in lighting) so I like to see these tips on electrical controls. This reminds me of soft eject mechanisms for cassette players (maybe I'm dating myself... :)
Great article/tip about using PWM with a lowcost micro to do LED fade-ins and fade-outs!!
I see that you put lighting into furniture. I am actively looking for artists to collaborate with for putting interactive and RGBW LEDs into artwork (yes furniture counts as artwork!!). Check out this quick little video and let me know if you are interested in trying one of our beta prototype kits. Thanks! -VoltVisionFrenchy
I recall a programmable, time variable, dimmer circuit that was in an old SCR applications book from the late 1960's. It did not require a programmed IC, and even more interesting, probably it could still be built today with equivalent parts readily available. Will that processor be available next year?
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
