7. Soldering Iron
8. Pliers etc.

Step 2: Drilling of Holes

Drill holes on the transmitter box. I made use of a sound blaster microphone box as holes are easy to make since the box is made of carton.

Step 3: The Connection

Solder the potentiometers, and 3.5" mono jacks to the individual transmitters for all 5 transmitters, solder correctly and prevent wire bridge as it may spoil the whole project

Step 4: The Assembling

Now fasten the potentiometers and the 3.5" mono jacks to the box. Make sure all wirings are connected as shown in the schematic.
