+ | * R4 - 330 Ohm (orange-orange-black-black-brown) | ||
+ | * R3,R5,R6 - 5.1K (green-brown-black-brown-brown) | ||
+ | * IC Socket - Solder one pin first, and make any adjustments if necessary | ||
+ | * Ceramic Capacitors: | ||
+ | * C2 - 0.1 uF (104) | ||
+ | * C5 - 1 uF (105) | ||
+ | * C6 - .047 uF (473) | ||
+ | * C7 - .0022 uF (222) | ||
+ | * C8 - .000010 uF (101) | ||
+ | * Electrolytic Capacitors (WATCH POLARITY!!!) - Striped location on the silkscreen indicates the negative leg | ||
+ | * C1 - 100 uF | ||
+ | * C3, C4 - 10 uF | ||
+ | * Headers - tack and align before soldering all pins! | ||
+ | * J1/J2 - 4 pin | ||
+ | * the big one - 10 pin | ||
+ | * Power input - tack & align | ||
+ | * Screw Terminal - P1 - tack and align - make sure metal part is facing out! | ||
+ | * Pots - resistance labeled on the underside - they' | ||
+ | * R2, R7 - 50K (B503) | ||
+ | * R8 - 100K (B104) | ||
+ | * insert XR2206 IC | ||
+ | * test! - set speed to 1-10 Hz, apply power, check with scope | ||
+ | * build the enclosure | ||
+ | * Further testing and learning about Oscilloscopes | ||
