Connect the open ends of the soldered wires to the relay switch VMA406

To automate the gun flip the two mono interrupters to ON condition.

Dismantle the nerf gun.

Now the gun will fire once it gets power supply, so the switch here is to connect/disconnect the power supply to the Nerf gun from the batteries inside the prosthetic socket

Connect the positive terminal (going from the E156176/ or any module which takes the power from the batteries in the gun and connect it to the NC terminal of the VMA406. Connect two male to female connectors, with the male terminals in the NO terminal of VMA406

One of the connectors should go to the positive terminal of the relay switch and the other should connect to the positive terminal of the audio jack. The audio jack is used to get the output of the IR sensor (which receives the input from the muscle flexing) to drive the circuit.

Connect the negative and the signal terminals of the jack to the negative and the signal terminals of the relay switch respectively.

For the swatter holder, laser holder, mobile holder, guitar plectrum holder, download the files from the files section and 3D print them.
