Electronic talking toys are fun, but the same old sound loops can get pretty repetitive after a while. This guide will show you how to swap out the original sound board for an Audio FX Sound Board loaded up with lots of your favorite sounds. You'll need a specific mask to follow along exactly, but these principles can be applied to nearly any toy designed to trigger a sound effect. Or, add a speaker and switch to the mix to give a voice to any prop or costume.

You'll reuse the mask's existing jaw switches and speaker, while upgrading it with a WAV/OGG audio FX board, amplifier, rechargeable battery system, and a power switch.

You'll keep the USB port of the audio FX board accessible for recharging the battery and updating the sound files whenever you like. You can even use the selector switch to choose from different banks of sounds.

 You'll need:

• Star Wars Chewbacca Electronic Talking Mask
• Audio FX Mini Sound Board 16MB
• Mono 2.5W Class D Audio Amplifier
• Lithium Ion Polymer Battery - 3.7v 500mAh
• Tactile On/Off Switch with Leads
• Lilon/LiPoly Backpack charger
• Rotary selector switch such as this and a knob
• Small Philips screwdriver
• Soldering iron and solder
• stranded wire (26AWG gauge)
• Wire strippers
• Flush diagonal cutters
• Double-stick foam tape
• Heat shrink tubing
• USB cable - A/MicroB
