Pretty difficult project (Nightmare Moon large acrylight), which lasted more than a year and a half.
On my side: designing of a simple optical system which focuses each LED’s beam, preparing file for engraving, engraving itself, making a frame.
On his side: preparing picture, polishing the acrylic plate, soldering, assembling, programming of the backlight.
Despite all the pitfalls, the final result looks pretty interesting (IMHO)
P.S. Many thanks to Gustol for his endless patience
