Alright, I realise it’s hardly original to post sounds recorded with a coil pickup. But well, these “mics” are just so fun and simple of use. So here are a few servos and such. I bought mine from Jez Riley French, and to my knowledge americans can have access to the same stuff in every Radioshacks.
There are sounds from a playstation 2 cd player, macbook, a blender, a yamaha QY70 and my blackberry.
Recorded with coil pickup in Sony PCM-M10
