Ever pick up a transistor without being able to read the part number to look up ? Or can’t find it when you look it up ? Well grab a multimeter and with a little know-how you might be able to figure it out.
First thing is to find the base, this can be done by measuring the resistance. Once you have the base figured out, then with the tip of your finger touching the base (acting like a switch) you can determine which one is the collector, and which one is the emitter. Sounds cool right ?

Whoops, sorry about that. Thanks for the fixed link, post updated.
