You can get by with fewer tools than I've listed; if you have em' great... if not, no big.

Tools

• 220 grit sand paper
• screw driver
• hot-glue gun
• hand torch
• soldering iron
• variable speed drill
• hand saw (for cutting the dowel)

Some of the parts might have tight tolerances... I plan on using a M3 tap to reduce the risk of splitting the plastic.

Alternatively, you could use the tip of your soldering iron to widen holes a bit.

Materials

• cute desktop speakers for the eyes
• 3D printed parts
• 2X analog feedback servo
• electret microphone
• 5X 3mm LEDS
• 3X 330ohm Resistors
• 4X 8mm M3 screws
  
• 10X 10mm M3 screws
• 2X M3 nuts
• 5X short wood screws
• 1X 20mm X 120mm dowel (usually sold in meter lengths)

• 5-minute epoxy

Grab your speakers and let's go!
