Unfortunately, I Really Am That Nerdy

Among other things, I got another USB-based flash drive for Christmas. I already had a USB 1.0 128 MB device; I got a USB 2.0 256 MB device, better in all respects- and it's SanDisk, rather than some Korean company I've never heard of before, so I'm more inclined to trust my data to it.

It has one really, really annoying habit, though.

The Korean drive indicates that it is active with a little tiny green LED at the end of its translucent casing. The SanDisk drive indicates that it is active with a really fucking bright blue LED that could act as a flashlight, at the end of its transparent casing.

Did I mention that I'm photosensitive? The thing blinks rapidly when it's accessed- and I'm extremely sensitive to blue glowy things such that it gives me a headache to have the damn thing in my field of view.

WAY TO GO, DUMBASS DESIGNERS. Why the fuck do they think I want a flashlight sticking out of my computer? Perhaps it's because it makes the entire casing appear to glow, which I admit is cool, but it hurts. I know I'm not the only one sensitive to that- the brightly blinking thing has to be distracting to everybody. What's so bad about a small discreet LED?

There's something in particular about blue LEDs in that they almost have to be piercingly bright. My new Pocket PC has one which fortunately is rather subdued, in order to indicate Bluetooth activity, but there's one on the front of my computer which illuminates the room quite well in the dark.

Incidentally, I wish my Pocket PC would stop blinking a red LED while charging. It means I keep having my eyes drawn to the right where it sits in its cradle.

Blinking lights in general that do not represent an error condition strike me as very poor design. Flashy things are to draw the eye- so if that's what you want, go for it, but if it's regular use, it's a bad idea. In a sense, I understand it on USB drives; it's an "I'm doing something, really!" indicator. But still, there should be some other solution...

I agree. I much preferred my old Pocket PC's indicator, which was a simple LED.. I can't remember if that one changed colour when charging was complete, but my Series 7 used a yellow LED which changed to green when it was done. No flashing involved.

The PPC does also flash while Bluetooth (blue) and WiFi (green) are active, also slightly annoyingly; it's fine when it flashes when a reminder is due, though.

Incidentally, I just thought, is the 'piercingness' of blue LEDs anything to do with their photon energy, or is that complete nonsense?

Blue is the higher range of light-wave frequency, so blue light essentially caries more energy per photon. Of course, one could just have something shoot out fewer protons, but that's not how things tend to work.

...It's 5:00 AM and I need sleep, you're making me think about Physics, which I haven't had for a semester, give me a break here! I might have an actual correct answer later...

*grins* Well, I have a quantum physics exam coming up this month, so it was on my mind.

Go to sleep! :p
