As 1800ES points out, light output can vary a lot in non-incandescent lamps (although I've also noticed dimming in those bulbs right before they stop working). I wonder if he's referring to CFLs and their habit of going from lower to higher output after they're switched on?
I agree with you about the dimmable light, Ann. And it looks like it stands a good chance of winning this round of Gadget Feeak voting. We'll know in a few days when we shift to the fifth round. If Andy wins with his dimmable lamp, that will be two for him, since he won the first round.
Ya, the devices that provide light these days are so varied, dimmers should be on all of them. You can't just grab a 75 watt bulb and know what you'll get. Next, let's work on a uniform and easily located volume control ...... the old knob was NICE!
My LED desk lamp is both practical and functional. I built 4 of them, which I use everyday. The dimming greatly enhances the utility of the lamps. I know of no commercially available LED desk lamps that are dimmable.
It's easy to find these projects in their full presentation. On the home page, look at the Gadget Freak posting and you'll see the word "all" at the top. Click this will get you to the full list of complete Gadgewt Freaks.
I hope the readers know that complete build instructions and parts lists are available elsewhere online. Obviously, the regulars will know that. I believe that how easy a gadget is to build might play a role in how attractive a particular project is.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
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.
