The world’s biggest subwoofer

To all my friends who care for this kind of thing I stumbled upon this article the other day

http://www.digitalgrabber.com/audio/the_60_inch_subwoofer.html

Its about a 60 inch subwoofer, it needs to be amplified with 1 MegaWatt of power. It can produce 188dB in a closed vehicle and blows the doors off normal cars. It’s air displacement is equal to the displacement of 160 10inch woofers to give you an idea of the sheer force of it.

Pretty cool stuff.

Skype – internet phone service

Today, I signed up for skype.

It’s really cool. For those who don’t know, it’s a service that allows you to phone, using your computer, to other people around the world.

It’s free to phone from computer to computer, but if you want to phone from your computer to a telephone you have to pay. The best part is that it is REALLY CHEAP. My first call, which went to my parents in Westville cost me 1/10 of what it normally costs me to phone them. In fact, it is even cheaper than a cellphone call.

It costs me US$0.075 or so per minute to call to South Africa. The cost to call to my home here from South Africa is even less, about US$0.03 per minute.

So, if you haven’t tried it out, go for it. There are other options, but this one has become quite popular. It’s a prepaid service, so you have to top up the credit before you can phone. The standard 10 euros is not too much, and will last a while. If it doesn’t work out for you, not much loss.

CamStudio Screen Capture software

This might only be interesting for those slightly more computer nerdy friends of mine.

Hail to open source and the GPL. This program is completely free and may be useful to someone. It allows you to “record” what is happening on your screen. You choose some options, click the record button, and then everything from that moment to the time you press stop is recorded as you see it on the screen.

If you don’t want it for any serious reason, it’s still fun to play with. Get it at…

Go ahead, it’s a good alternative to computer games and solitaire, although the novelty might wear off. Hey, you might even do something productive with it.
