How to build an Audio Looper, EX: Boss RC-30 or RC-2

[The_Bloody_Omen]

Does anyone know how to make such a contraption, maybe out of some duct tape or toothpicks perhaps? Only recording several seconds would be satisfying as well.

Thank you

Thereare several such projects floating around, using telephone answering machine chips.  They don't provide exceptional recording time, or saving multiple loops, or fabulous 96khz/24-bit resolution, but they ARE cheap to make and do the basic function of playing back what you've recorded, again and again and again.

How the heck did you find that lol, every time I ask for a looper in the google machine I get those true bypass "loopers", they should call them "stringers" or something else idk; However, thank you very much for the infromation Mark Hammer and rousejeremy, it will help alot.
