100K resistors x 2
Jumper wires: female to female
Shrink wrap: 3/4 inch and 3/8 inch
Step 1: Solder the 5 pins onto amp
Step 2: Strip the black housing off of 3 jumper wires then pull off the female connectors. You will need to solder them onto the resistors.
Step 3: Now we are going to shrink wrap the bone conduction transducer to the frame of the glasses. Take the elastic end of the glasses off the side PiGlass is mounted to. Slide the 3/8 inch shrink wrap on the frame and then feed the wires through, the transducer should be on the inside of the frame. Now put about an inch and a half of the 3/4 inch shrink wrap around the bone conduction transducer. Make sure the transducer sits above your ear, essentially above your ear canal. When you find the right placement carefully use a heat gun or hair dryer to activate the shrink wrap.
Step 4: Take the bone conduction transducer leads and solder them to the positive and negative speaker output.
Step 5: Attach a wire to 5v and ground on the phat dac, then attach the other sides to ground and vin on the amp. Next attach the resistors to the phat dac pins and A+ on the amp board, now you are good to go.
