A Couple Made These Beautiful Badges as Wedding Favors

Weddings are expensive, and most couples pour money into the venue, flower arrangements, dinner, and reception party. Unfortunately, the only things they get to keep from all of that are memories and photos. Wedding favors are a great way to give guests a lasting gift to remember the occasion, and they also give the happy couple a chance to exhibit a bit of their personality. For Atika and Simone, a pair of electrical engineers, badges were the obvious choice for wedding favors, and the results are fantastic.

Like most other badges, these are a work of art and creative expression. With clever use of the PCB color, soldermask, and exposed copper, they came up with a design that beautifully illustrates the bridge and groom. A total of 72 tiny 1x1mm 0402 SMD LEDs light up the badges. 18 of those are standard single-color LEDs, while the other 54 are RGB LEDs. Two capacitive touch pads are used to switch between the available lighting effects.

Those LEDs are controlled by a Microchip PIC16F18326 microcontroller through a IS31FL3218 LED driver chip. The only other components are a handful of SMD resistors and capacitors. Those, along with the chips, are soldered to the back side of the badge and covered in a protective layer of black hot glue. The entire badge is powered by a single CR2032 battery. In total, the couple made 25 of these badges for their wedding, which was on May 6th of 2018. We weren’t in attendance, but we’re sure the badges were a hit with the guests.
