Here is a list of parts that i used
1- DPDT toggle switch
1- Momentary Switch with roller
1- 4 AA Battery holder
1- Rc Servo
1-Broken Speaker box (can be any kind of box)
and along with some basic tools and skills like (Soldering iron, Solder, Wire, Screw driver(s), Heat shrink)
Step 1 Gather all of your materials
Step 2 Remove servo horn and bottom screws, remove bottom, remove top carefully(dont loose gears) and cut the black 180 degree limiter and white on on top of the main gear.
Step 3 Cut the Wires and connector off and Solder the red and black wire to the two power leads and put everything back together
Step 4 Wiring Look at diagram
Step 5 the case, cut hole for switch, mount switch and servo (i used the end of a coat hanger for the arm fastened by superglue and screws) mount momentary switch and battery pack and trap door and done. (I did not go into detail because each box is different) I also added a rubber stopper so the arm would not slip off the switch.
Basicly what happens is when the system is in the off position the momentary switch is pressed down by the arm. When the switch is turned on the servo turns on moving releasing the momentary switch until the switch it in the off position and then because the polarity is switched in the momentary switch the servo reverses direction until the power is cut when the arm presses the momentary switch.
