I'm working on a couple of Jawa costumes for my son and baby brother to wear at the upcoming AdventureCon in Tennessee. To add that extra umph of realism, I decided to make a Jawa voice module. The total cost for the project is around $20 and is easy to make with parts from RadioShack.
Step 1: First, go to RadioShack and get all the parts you need
Here are the parts you'll need:
9V Recording Module - RadioShack catalogue number 276-1323 : $10.99
1/8" Mono Phone Plug - RadioShack catalogue number 274-0286 : $2.99 (pack of 2)
Enercell 9V Alkaline Battery - RadioShack catalogue number 230-0853 : $4.49
Also, you'll need a soldering gun and very thin solder.
