Step 2The Electronics
Parts:
Velleman "Super Stereo Ear" (MK136) Kit
2.2K ohm resistors x 2
Instructions:
This project is based on the Velleman "Super Stereo Ear" (MK136) Kit. I only changed the value of 2 resistors that connect to the + side of the mic and +V (R1 and R2 if you refer to the kit). The value of these 2 resistors should be chosen according to the impedance of the mic. For WM-61A, it should be 2.2K, but some other Electret Condenser Microphones may have a different value.
Building this kit is easy and is well illustrated in its manual. If you design your own circuit, then probably you do not need to follow any further instructions here.
