Step 1: Soldering
DO NOT DO STEPS 5 & 6 Yet Wait Till End Will Use Battery Cell & Jumper Wires
Step 1: Attach 1k resistors (Brown,Black,Red) to R1 & R2 then Solder
Step 2:Attach 10k resistors(Brown,Black,Orange) to R3 R4 then Solder
Step 3: Place Trimmers into Circuit Board (Both are 220k): RV1 & RV2 then Solder
Step 4: Place transistors into :T1 & T2 then Solder (It is fine if it sticks out a bit make sure it is flat though.)
Step 5 Solder jumper wires into circuit board: LD1 & LD2 then Solder
Step 6:Attach LEDs to jumper wires (Make sure negative side of LED is connected to negative side of jumper wire)
Step 7: Solder Battery Holder into circuit board: 9V (Solder into corresponding sides)
Step 8:Place Batteries into Battery holder then turn on
Attachments
Step 2: End Result
Change jumper wires for fitting length depending on Prop.
