If you want a train for under your Christmas tree but don’t have a lot of money to spend, here’s how to find one and what to ask for. Find a store that deals in used Lionel trains, or find a local hobbyist. Search Craigslist or your newspaper classifieds for an ad stating, “I buy [...]
My latest lighting experiment is a 900-lumen bulb from G7, which is rated at 9 watts and priced at around $16. It’s advertised as equivalent to a 65W incandescent. I’ve had two of them for about two months now, and my initial impressions are favorable overall.
Timothy Hunt asked me (via Twitter) if I’ve seen the lightbulb reinvented, an LED bulb that screws into a standard socket but has wi-fi capability so you can tune its light temperature and otherwise control it with a smartphone. I hadn’t. But I found it interesting, and appreciate the mention.
I learned something incredibly useful this week: For every 3 watts of energy consumption you save, you save an additional watt of power in cooling costs during the cooling season. I bought my first CFL bulb a little over 9 years ago. I knew this was helping my AC costs too, but now I know [...]
Micro Center had the Inland warm white A19 LED bulbs on sale this week and had a hard time keeping them in stock. I snagged an 800 lumen (60W equivalent), non-dimmable bulb, which uses 10 watts, for $13. It’s not the state of the art in 10W LED bulbs, but the price is right and [...]
PC Magazine asks when it’s worth upgrading to the new Philips L Prize-winning LED bulb, lamenting its high price and long payback time. I can only say what I plan to do, based on my experience with high-efficiency bulbs. I was one of those guys paying $9 for CFL bulbs nearly a decade ago.
Sometimes you want to know how many volts your train transformer is feeding your trains, in order to avoid damaging the motors. And it’s also helpful to know how many amps you’re pulling from your transformer, so you don’t damage the transformer.
Bill Gates says the rapid advance of computers created unreasonable expectations for the advancement of energy technology. The argument makes sense. And while desktop computers did advance very quickly, I think people have a misconception of even how quickly computers developed–which makes it worse, of course. Some people seem to believe the computer was invented [...]
I saw this week on Cnet that Pharox is selling basic, bare-bones LEDs direct from its web site, hoping to get consumers to try out LED bulbs. The Pharox 300 is a 6 watt, 360 lumen bulb priced at $6.95. The Pharox 200 is a 5 watt, 240 lumen bulb priced at $4.95.
It was like ordering Chinese takeout. I wrote yesterday about how I needed a motherboard to try to solve my ongoing webserver issue. I don’t live or work anywhere near Micro Center. The computer store near my house closed, and I don’t like the one near my workplace anymore since they jerked my friend around. [...]
