Making 2 Lo-Fi Microphones From 1 Old Telephone Handset

I decided to attempt to make a pair of Lo-Fi microphones from an telephone handset. One mic is made from the earpiece and the other from the mouthpiece. The carbon microphones used in these handsets require power so I rigged up a simple circuit around a 9V battery. Both mics sound pretty cool.

Intro @ 0:00
Part 1: Passive Speaker Mic @ 1:08
Part 2: Active Carbon Mic @ 3:41
Part 3: Sound Test @ 9:00
Part 4: Final Thoughts @ 9:48
