Among the more pointless things I’ve done recently is install a blacklight CFL in my bedside lamp. This is to encourage me to take up reading books again. Do you follow? It’s a simple idea really. I’ve grown so used in the last decade or so to reading from screens that paper seems a bit weird now. But turn on a UV lamp and what happens to a book? It glows. Like a screen!
Bleaching agents in the paper must make it fluoresce. Not all the fibres seem to have it equally though, and the page takes on an oddly speckled, grainy look. It is bright enough to read by though, just about.
All right to be honest this isn’t really why I got the bulb. I bought it because I’d never seen a blacklight CFL before, it wasn’t expensive, and I thought it was too interesting not to buy. In action it seems more violet than invisible, but white things around the room glow in an eerie way. The shirts I have hanging look particularly fierce, and the pale neon emanating from my map of Europe hints at the trippy possibilities. This all gives the room an… interesting look – somewhere between clinical laboratory and tatty ghost train.
And I notice that it actually makes the photochromic lenses of my glasses go dark, so it really does seem to put out a healthy (?) amount of ultraviolet light. Perhaps if I sleep with it on I’ll get a tan this summer.
I was saying that by turning off the always-on data connection, my Android phone will get through a full day with plenty power to spare. And that’s not jealously husbanding the battery either, but fully indulging what the phone can do. Including 3G data – when I actually want it.
Pretty neat, but what when I want to really rip it? Actually spend a whole day browsing, for example. While simultaneously live-streaminggeotagged video. Desire expands to meet the limitations of the battery.
And yet, there is a way to have effectively endless battery life. How? It’s simple. Charge one battery while you use another.
You own a spare battery, right? Oh, you have an iPhone. I’m sorry. I suppose you can charge a spare iPhone.
There are a number of solutions to charging a battery while it’s not in your phone. This though is quite the tiniest I’ve ever seen. I saw some of them – different brand, but identical device – in my local electronics shop on clearance for 60 cents each. What to lose, I thought. A couple of days later I came back and bought all the ones they had left.
It works for many common phone and camera batteries. You adjust its prongs to match the contacts (an LED tells you when they’re right), clip it on, and plug it into any USB socket. It’s really about as no-frills as charging can get, and it weighs a barely-perceptible 11 grammes. Worth carrying just as an emergency backup in case you lose, break or forget your normal charger. It even has key ring!
I’m fortunate in that Samsung provided a collapsible travel charger, so I can fit that, a short USB-to-microUSB cable, the spare battery and one of these chargers all into an old glasses case. Plus headphones and spare stylus pen. That’s all I need to charge the phone or the battery. Now I can travel forever.
