Mason Blaster
thingiverse
Transform your mason jar into a mono speaker system with a 2" speaker via this print! Attach the electronics and battery onto the electronics plate that fits into the lid's grooves. The LM386 amplifier powers the audio system, while an ATtiny85 microcontroller manages the RGB led light display in the frosted jar. For future improvements, consider using FFT to create dynamic light displays based on music. Check out this Vimeo video and schematic for detailed instructions!
