    Thumbs up A few stuck columns, but IT WORKS!!!

    Hey everyone,

    The boys and I finished up the final wiring on our LEDTriks panel the other
    night!

    I have a video of it in action on the LEDTriks link on my site below if you're interested in checking it out!

    It has 3 or 4 stuck columns, and I need to troubleshoot those, but MAN IS IT COOL!!!

    Pulled your video. Lookin' good, Kevin! :-D

    Man that's a good lookin' wiring schematic on your site! :p

    I tried my first panel yesterday. It just sat there and looked at me. I verified that data was getting to the 74HC4514 with a scope, but nothing was going out.... These arrived loose in a plastic ziplock freezer bag and CMOS is very ESD sensitive..... I'm going have to order replacements.

    So I built the enclosure for it instead. My spacing was 3/4", so I'm able to make a 6' long plexiglass cover from Home Depot work.

    Did you drill your own, or were you fortunate enough to find some pre-drilled at 3/4 inch?

    I drilled those in mine. Actually, I conned the wife into drilling them after I made the template. I clamped two sections together so there were 768 holes to drill to make two Triks panels.

    Very Clever! Much better than my thoughts of buying a 4 X 8 board and drilling 1536 holes........:oops:

    Just curious, where did you get the chips from in Ziplock bags?

    Ben's Coop.

    EDIT: Ben is off the hook. I received replacement parts today (4/22). It ended up being the sample alegro chips that were bad. Go figure. These were the free ones shiped in ESD proof foam and plastic case. All six were bad. I fully expected the other parts to be bad since they had no protection, but they weren't. I now have a few spares. If anyones interested in them, let me know.

    The Triks are functional! (Some adjusting to be done. I think I may have offset a column.) Some LEDs seem to fire brighter at times than others. There's still some investigating to be done, but at least it can be read!
