This stuff is great. I know that this isn't "linux" related, but i bought a couple if 555 IC as per the previous suggestion to make a high pitched siren.

Next I'll move on to the following suggestion ... "makes you need to go poop ... now" noises. This 555 thing will take me a while, i need to brush up onmy soldering skills.

thanks for the ideas :),
