Switching Off Appliances Still Draws Power

My previous post about power adapters got me interested in electricity and it led me to this article on how there are vampiric devices in your home, sucking energy all the time. I got pretty surprised when I read the article (Read the full article here: http://www.electronichouse.com/article/why_your_electronics_suck_energy/). It turns out that all our appliances still draw electricity even though they’re turned off. I know that they require SOME electricity, especially things like DVD players which have an internal clock —

Best International AC Pocket Socket / Plug Adapter Review

I just returned from a short trip to Taipei, and while it was really fun, it’s nice to be back home. Taipei’s (Taipei Travel Guide) surprisingly not very different from Singapore, except the mild winter’s there currently is a welcome change from Singapore’s all-year-round tropical climate (Singapore Travel Information). Another difference that got me was the power sockets — Taiwan uses a 2-pin blade socket configuration that’s different from Singapore’s 3-pin rectangular configuration. I brought a 2-pin converter, but with

I’m leaving for a trip to taiwan this Monday! To Taipei in particular, and I’ll be away for 7 days 😀 I’m in the midst of packing now, and I realised how useful these bottles are.

I was editing a PHP script today when I realised that one of the files did not allow PHP code. Weird. But the annoying thing was that I NEEDED it to run PHP code — or rather, I needed it to randomly display an image with a link. So I had to find other means, which turned out to be good ol’ Javascript. The code below will allow you to use Javascript to randomly output or show an image with

I want to change my Treo 650 to something like the Samsung i600 (Blackjack)

I want to change my Palm Treo 650. Don’t get me wrong – it’s a great phone, an excellent phone in fact! But these days it’s becoming too much of a giant in the land of the slimmies. Plus, it doesn’t have Wi-Fi, which is quite a big drawback since I can get a free wireless connection pretty much anywhere these days. I love the keyboard though – I type amazingly fast compared to my friends who are using the
