Very small sound meter!

Reviewer: from HOUSTON, TX USA

I bought this many months ago! But, I just built it last week! Man, does it have a lot of resisters!! Unfortunately, I messed up the board! I used my soldering gun (100W), instead of my soldering iron(25W)! OOPS (lifted pads, damaged)! !!! Does not work! My fault... Nice little kit! I was looking forward to this...Next time!!
I tested parts, first! there ok, I saved the transistors and led's!!
