“Ba-DING!” The classic 8-bit chime from our favorite retro video game finally makes a triumphant come back as a Mario question block necklace.
It’s so tiny and adorable you're probably wondering, “How much?” This is custom…you can only make it, not buy it!
In this DIY project, we'll show you how to build the Mario coin sound jewelry so you can wear it and learn about electronics and 3d printing.
- Trinket 5V or 3V, or Gemma - any will work, we show using a 5V Trinket here
- LED Sequins (warm white, or any color if you prefer) (photo shows a single LED sequin, was later decided that two looks better)
- Slide Switch
- 100mAh LiPoly battery
- LiPoly backpack - for recharging the batteries
