This is a great video, but its really lacking the textual information that benefit most Howcast videos. You're talking pretty fast and running through a lot of technical information quickly. If you included the ";What you'll need"; bullet points and clear, clickable steps within the timeline, this would be a lot easier to follow. This is really cool, and I'm considering trying it, but you should take into account that most viewers (like myself) aren't familiar with soldering circuit boards.

hmmm... i don't think this will work with the schematic he provides (at around 00:47sec). The schematic should look more like this: http://img242.imageshack.us/my.php?image=schir8.jpg otherwise it looks like the siren will ALWAYS be on (+9V to the base of the NPN).

Too complicated. Slow down the instruction narrative, explain where to get the components
