Shitty Add-On Oreo Construction Test

Boards are assembled using small, 0604 red LEDs as that's what I had on hand. Pics:

The test worked well as far as illumination, however, I don't believe the LEDs I'm using can light up an area this large. This test would work better with smaller illuminated areas.

This is a continuation of the Oreo Construction project, where components are encapsulated inside of PCBs: https://hackaday.io/project/162612-oreo-construction-circuitry

The Shitty Add-On movement continues on, and there are more and more boards featuring reverse-mounted LEDs. Reverse-mounted LEDs don't lend themselves to pick and place assembly, so this is a project to see if another technique can be used (Oreo construction) to make flat, illuminated panels in PCBs.

Right now, this is just a test. It's a 50mm square board with a Shitty Add-On V.1.69bis connector. There are three 'windows' or 'panels' in this test, each of which can be illuminated individually. It's not artistic, and it's not very technical, even; that's not the point, this is just a test to see what's possible.

This project consists of three boards, a base with all the circuitry (on a 0.6mm PCB), a spacer (1.6mm pcb) and a top cover (0.6mm). Here are some pictures:

The boards are ordered, I did the top cover in red soldermask. I'll finish this up in a week.
