William Grill wanted to customize the lighting for a model or simulator with a bit of illumination to create a nice touch. He wanted to move beyond a simple on or off and add a touch of refinement to a presentation. He created an inexpensive controller to do just that. His fader is based on a MicroChip 10F200 controller that includes both a fade control and mode settings to select both the fade rate (in seconds) and the internal processing for use with either a momentary button (push on, push off) or STST (single pole, single throw) switch.

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?
Followers of Design News’ Gadget Freak blogs will have the opportunity next week to take home a wireless remote demo package that can be used to build garage door openers, tire pressure monitors, keyless entry systems, and much more.
The 2015 Gadget Freak of the Year goes to the DDV-IP -- or, a Drink Deliver Vehicle – Inverted Pendulum. The gadget is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on a hot summer day. A wireless RF remote enables manual control of the device beyond the act of self-balancing. All of the features of the DDV-IP result in an effective delivery vehicle while providing entertainment to the users.
