Step 1: Moding the Servo
Take apart the Servo by unscrewing the 4 screws holding the servo together.
Step 2: Moding the Servo
Use a pair of wire cutters to cut off the 3 wires.
Also cut off the wires from the input connectors.
Step 3: Moding the Servo
Using only 2 of the wires, strip it, and solder them to the connections shown above.
Step 4: Moding the Servo
Open the top side of the Servo and remove the gears
Use a pair of cutters to cut of the plastic tip of the servo, as shown above.
Step 5: Moding the Servo
Also clip of the little nob on the one of the gear , shown above.
Finally, put the servos back together.
Step 6: Wiring the Servo
Solder the battery pack (on the outer pins)
Solder the Servo (middle pins)
Making sure the positives/ negatives are on the same side.
Step 7: Wiring the Servo
Solder a piece of wire from positive wire of the battery (top left) to the empty pin across from it (bottom right).
Solder the micro switch using extra wires to the negative wire of the battery (bottom left) and the empty pin across (top right).
Step 8: Finishing the Servo Arm
Laser cut out a wooden piece of swing arm.
Attach the arm to the servo using screws.
You can make as many as you desire. ( I made 3 in this case)
Step 9: Making the Box
Laser cut out the required pieces to make the box.
And construct it using hot glue or other type of glue
Step 10: Putting It All Together
Attach the Servos to the inside of the box.
Drill holes that align with the arm on the top piece of cover.
Glue in the micro switch so when the arm swing back, it touches the micro switch.
Step 11: Done!!!!
Finally attach the covers using hinges. and you are ready to go!!!!!
