Hollowed out Star Trek Lower Decks Phaser

I loved this model but wanted to add in electronics to make it work. (Its pretty janky though)

Description

PDF

I combined two adafruit tutorials to create this:

https://learn.adafruit.com/gravity-falls-memory-gun?view=all

https://learn.adafruit.com/lightsaber-rp2040?view=all

Here are the parts I bought from adafruit:

  • Laser Diode - 5mW 650nm Red
  • Thin Plastic Speaker w/Wires - 8 ohm 0.25W
  • Adafruit RP2040 Prop-Maker Feather with I2S Audio Amplifier
  • Lithium Ion Cylindrical Battery - 3.7v 2200mAh

I already had buttons and wires and solder and I've attached my code with the changes I made. I left some of the light saber code included but commented out in case you want to add some more effects.

 

 

 

Model origin

The author remixed this model.

Differences of the remix compared to the original

There are hollowed out bits so that electronics can fit inside and a laser can emit light from the front!
