 +  * Resistors:
 +    * R1 - 1K (brown-black-black-brown-brown)
 +    * 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'​re also incredibly loose on the board, so tack & align!
 +    * 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
