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?
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... :)
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
