The following lists are divided into 2 categories. The first category consists of things you NEED to complete the project, while the other list consists of things that are very HELPFUL.

Things that you NEED:

• Shoes (duh!)
• Piezo electric elements (x14) I found 15 of them for 15.99
• Rechargeable battery pack w/ charger(x1) I got mine from 5 and Below for 5$
• Hot glue gun w/ hot glue
• Soldering iron + solder
• Foam/cardboard/anything you can squish (I used foam board that I got for 1$)
• Access to a 3D printer (If you do not have access to a 3D printer, you can always substitute a different material/plastic, but my instructions will be based off the 3D printed design
• 1n4001 - 1N4007 Diodes (x4) OR a CFL lightbulb, which I will show you how to take apart in order to salvage diodes needed for this project.

Things those are helpful:

• Dremel tool
• Helping hands
• Velcro strips (HIGHLY RECOMMENDED!)
• Multimeter
• heat gun (if taking apart CFL bulb)
• ruler/caliper
