Step 1: Connecting individual EL panels
I don't have photos of the manufacture of the individual 5-panel panes. However, the basic idea is visible in the photo. Each of the 5 EL panels was attached to a piece of acrylic with a dab of hot glue, with the two leads passing through small holes to the back side. One lead from each EL panel was bent to the left and the other to the right. Then I laid 6" stripped copper wires across the left and right sets of leads, and soldered the leads to the wires. More hot glue secured the wires to keep them from wiggling around and possibly breaking the delicate leads.
Step 2: Gluing and connecting the panes
Step 3: Finished!
Originally I thought that 25 panels would produce more light, so my idea was to make this a small desk lamp or bedside reading light. However, it doesn't produce enough light to read by, so I made it a hanging light instead. It seems about as bright as the full moon shining through a window, and it looks really cool from outside, like a glowing japanese paper lantern.
