As far as I could see it’s not on site… which confirms right decision to avoid writing about concept ideas (for gadgets/architecture) afterwards. This was the first article in the Green architecture category.

Comment on LED lamp can be powered “for free” by your phone line by johnc https://www.robaid.com/gadgets/led-lamp-can-be-powered-for-free-by-your-phone-line.htm#comment-270162 Fri, 19 Jan 2024 03:18:26 +0000 http://www.robaid.com/?p=1979#comment-270162 If you used led lamps with batteries you can the phone co juice to keep them charged. No worries about incoming calls.
I think the phone company ought tout this as reason to stick with landlines.

Comment on Longevity of light bulbs and how to make them last longer by Andrew Carmichael https://www.robaid.com/gadgets/longevity-of-light-bulbs-and-how-to-make-them-last-longer.htm#comment-257166 Fri, 10 Dec 2021 19:14:04 +0000 http://www.robaid.com/?p=5815#comment-257166 Halogen lamps are the worst for burning out almost as soon as you buy them so Over the years I have done quite a bit of research to find out why and how to prolong life for ridiculously long periods of time. My Halogen down lights in my bathroom for example are all still going strong now for over 15 years whereas the ones in my kitchen all burnt out within weeks and have now been replaced with LED lamps. I regret to say however that even the LED lamps haven’t lasted anything like as long as the bathroom lights. So what’s the trick?

Turns out that Halogen lamps burn much hotter than regular filament lamps & this means that the resistance change between on and off is proportionately greater too. What kills halogen lamps is the sudden surge of high current when you turn them on and this is down to an inherently low OFF resistance. So the solution to the problem is simply to limit the turn on current until they warm up. In the bathroom I am using a good old fashioned transformer which saturates during switch on. There is a much simpler & cheaper solution however and that is to use a so called NTC device in series with the lamps. (that is negative temperature coefficient device). These work the opposite way round to filament lights. At off time they have a high resistance but as they warm up when ON so the resistance drops. In my garage I’m driving 20 halogen lamps (normally unheard of) in series with an NTC and nothing has failed in 3 years!.
