**$99 !!!!!!!

**If you are interested in this type of photography and want to build a sound trigger or IR trigger better to go to www.hiviz.com they sell the complete kit ready to assemble for $12 ! 

OK it doesn't look quite so finished off as it is components on breadboard  but I can personally vouch their kits work and that the guy selling them is very helpful if you get any queries.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
