When you close your car door, the lights may go out immediately, fade or they may stay on interminably while you stand there wondering if you closed the door all the way. Bill Bowden has devised a gadget that lets you take control of your interior lights. Bowden’s Automobile Interior Lights Fader lets you determine whether the lights go out right away, fade or stay on for a few seconds. You can even program the fade times to fast-on, slow-off or vice versa. The device’s circuit is intended for cars that have a door switch that supplies a ground to the interior lights with one side of the lights connected to the positive side of the battery through an appropriate fuse. With a few modifications, the device can also be used without a door switch.
The first vehicle I had with the delayed off was a 97 GMC van. I was unaware of this feature and looked all over the place to find how to turn the lights off. Finally I read the owners manual (instructions are only for people who do not know what they are doing) and it mentioned the delay. So I closed the door and timed the light, 13 seconds. Only after doing that several times, did I feel confident to just walk away.
Of course when one of the kids left a dome light on, no one noticed until a neighbor phoned about 4 hours later, but that is a story for another day. I like that your device allows the owner to reassume control. What a novel idea.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
