Prom Invitation

How does one go about asking a crush to a Junior Prom? I wanted to ask her to the prom with something that was memorable, impressive, and certainly one-of-a-kind.

With a basic criteria in mind, I knew I would need my Pink 1/8th acrylic sheeting, some 10-32 bolts, a nice chunk of high density polyethylene from a cutting board, a momentary contact switch, battery holder, and most importantly; around 40 green LEDs.

What exactly does one concoct with this pile of materials?

Now to rewind to my usual buildlog:

From the start, I drilled holes for LEDs to spell out ‘Prom?’ in a piece of polycarbonate

And wired the diods together

Next, I had to come up with a way to make my message a surprise for her, so I put a piece of printer paper in front of it, sandwiching that between polycarbonate and tinted acrylic.

But the idea of that actually working was just speculative, I had no actual idea of whether or not the lighting would still shine through, so I naturally yanked the 3v battery from my phone and tested my invitation out.


And on top of everything else here, I had a date to the Prom!
