I made a project called Electronic Matrix - I Love You, meaning it is a hardware project that says "I love you" as an electronic matrix LED display. Which is cute and the name of the project if you get the first letter of each word in the project name you can create a name called "EMILY" which is my long term girlfriend soon to be my wife.

I won the contest way back in 2017 as Grand Prize winner from Instructables' contest called "Valentine's Day Contest 2017"
