Jurek and the Amazing Techno, Colored DreamWall

Jurek and the Amazing Techno, Colored DreamWall

The title is mostly a placeholder, as I haven't really figured out a name for it yet. This project is a wall hanging that consists of semi-large triangular pixels using discrete RGB LED's and PWM to control intensity levels of each LED, resulting in a 4096-color display.

More soldering and gluing

Soldering
12 more (2") LED triplets soldered. 88 done, 152 to go. The 2" sections were kinda tricky, because the wire length was so small and the heatshrink tubing needed to be a certian length just to go over everthing properly. I ended up having to rearrange a few steps in the process to get everything assembled correctly.


Gluing (a.k.a. Construction)
I cut and glued 4 more pieces to the outside of the 1st module. They were all 3"x5.5" pieces. That leaves another 10 pieces on the outside zig-zag part left to cut and apply. For this module, I also need to make room for the battery pack, so I have to extend the bottom side pieces an extra bit, plus have a second long piece on the bottom. The exact dimensions are yet to be determined (I haven't been ambitious enough to sit down and do the measurements). It involves angles and what-not so it's not entirely nontrivial (yay double negatives! Me fail english? That's unpossible!).

Parts
I also ordered 170 2x2 connector housings (sockets) and 500 crimp connectors. The connectors weighed in at a whopping $1.28 each, so the total order ended up being over $250 for just those items (the crimp connectors are very cheap).

This last Digikey order put me near $5k ($4.8k). Lots more to come in that department though. Yet another milestone, I guess. Or something.
