I combine all my projects in making class into a theme game called “zombie rush”
In this game, you can play games with the gears you choose
If you score high enough you can get a real one as a reward
Instructables:
Rocket shoes:https://www.instructables.com/Rocket-Shoesinfinity-MirrorRGBLED/
Ray gun: https://www.instructables.com/RayGunZoombierushgear/
I still working on the last gear “raygun”
Parts are sent to the 3D printing
Here are several GIF i made



Here are my process of making ray gun
Thanks to the great tutorial from Ruiz Brother
Here are material List
- Audio FX SoundBoard
- Pro Trinket 5V/3V
- PAM8302 Mono 2.5W Class D Audio Amplifier
- Pro Trinket LiIon/LiPoly Backpack Add-On
- NeoPixel Ring 12 x
- Laser Diode
- 500mAh Lithium Ion Polymer Battery
- Mini Metal Speaker
- 6mm Slim Tactile Switch Buttons
- Slide Switch
Tools & Supplies
- 3D Printer
- Filament
- Soldering Iron
- Solder
- Panavise Jr / Helping Third Hand
- Wire Strippers
- Flush Diagonal Cutters
- Flat Pliers
- #4-40 3/8in Phillips machine screws and nuts
- Adhesives (E6000, superglue, etc.)
The 3D print files are very detailed.
You only need some sand to make a flat surface for adhesives to work.
Soldering needs some skill to put both wires into one hole
The most frustrating part was trying to connect adafruit board.
It might be a laptop issue.


unable to find port
