I just finished my bulbclock build last night. I had a lot of fun with it, and it almost went off without a hitch. Everything was fine until I got to the red LED ring and was connecting it to the clock. I thought I had a potential solder bridge between one of the LED connectors and a leg of a red LED, and in my enthusiasm to cut it, I ended up twisting and lifting one of the LED leg pads off the PCB. I tried not to panic despite the other LEDs going crazy when I tried to light the problem one, and followed the trace to the next solder point. Luckily it was very close and I was able to solder a very tiny bridge made out of a cut off LED lead. It worked like a charm. In reading other troubleshooting posts, I guess the erratic behavior with the pad lifted was due to charlieplexing and one LED being missing. Anyways, as always great kit. I'm decent with electronics at this point, but it's so nice to see a very well labeled, thought out kit and instructions.
My question is related to a very large shadow that the LEDs cast. In reading other posts, this appears to be due to the newer wide LEDs that were chosen for more recent kits. What was the reasoning behind using these versus the older ones? Is there anything I can do to minimize the size of this shadow from the LEDs? It makes it almost impossible to see the minutes hand when it is overlapping. I believe the LEDs are all mounted correctly so I don't think that is coming into play as a factor. Thanks for any suggestions!
Oh one other question, I also ordered the rear projection back but currently have mounted the white one. Dumb question, but what is the difference between the two?
