[QUOTE="Whitey-, post: 134316, member: 39146"] At this stage I decided to pivot to using the chromatrim strips as driveway liners. My current config was wall mounted skulls, pumpkins, scorpian/spider (one each side) and ghost - all mirrored each side of the driveway - plus the boscoyo skull and crossbones in the middle as a singing face. Adding 400 extra lights to this mix became my downfall. As darkness fell, I got dad to help mount the skulls (Geralds) for me. The soldering and hot glue in them is pretty dicey, and unfortunately they're the primary link up the stage left side of the driveway. [ATTACH type="full" width="233px"]24209[/ATTACH] [I](Note this is an earlier revision, the later ones used Ray Wu connectors. This one went up with a JST -> Ray Wu adapter I made and held fine 😂)[/I] The left side was on one output. On a second output was the stage right side of the drive, and the skull and crossbones singing face on a third. These all worked very well on the pixel tester... but not on my circuit. I don't have a photo, but after about 80-100 pixels it would drop, and the lighting leading up to it was faded for sure. I took my trusty multimeter, and was still getting 4.2v at the drop point. What gives? The pixel tester was also lighting along fine there and beyond at the same measurement. It took me a minute to realise. My 3.3v logic was fine on a short run (which is how I'd been testing). Dropping down to (I assume) around 2.8-3v wasn't a problem.. until I added 200px extra per run. At that point, my 'high' I guess was a 'low' on a 5v circuit - below the threshold. Doh! I had bought 3.3v/5v (HV/LV) logic converters very early on in the blinky light process, not fully understanding what they were. When I build the circuit above, I saw that my lights worked off my 3.3v logic and completely moved on to other focuses, as I was time crunched for all my props and pixel pushing (try saying that 5 times fast!). I began to solder a hacky connection up, but I ended up not connecting the ground somewhere (I assume, given the flickering when I next turned it on), and by that point it was 9pm and I had to call it. The cable box was a mess (I'd added a new output for the skull and crossbones during this time too, and I used about 3 different joining methods across everything connected). [ATTACH type="full" width="342px"]24210[/ATTACH] I left my one side of the driveway on the pixel tester to at least give some light to the driveway for the evening.

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
