[QUOTE="jcarlton, post: 76712, member: 22201"] I've looked at the [url=http://auschristmaslighting.com/wiki/HD712]Ray Wu 27 channel controller[/url], but for a similar price per pixel I thought I'd support the efforts of AAH I only purchased a single set of 2-wire fairly lights (some pink Lytworx string from Bunnings) this year, which I understand run with alternating polarity that cannot be properly controlled with the current range of DC controllers. Thanks to this community I purchased these knowing full well they cannot yet be computer controlled, but with the intention of only using them to decorate my static indoor Christmas tree. I've investigated this, and understand that this testing would require the purchase of a [url=http://www.ebay.com.au/itm/321899843741]variable power supply[/url]. For the number of existing strings I have I don't think it would be worth it for me to invest in one of these at this stage, nor the multiple power supplies I may eventually need run the strings at slightly different voltages. I'm hoping that ~30v will be "good enough" for all (or at least most) of my strings. I suspected that this may have been the case, and I must admit that I haven't taken the time to actually go and see any pixel displays in person. Unfortunately with a 2, 3 and 5 year old, and the sun only just setting @ 8:45 in Melbourne in December it makes it a bit difficult. (The age of the children also go a long way to explain why I've put off this project for the past 3 years) Unfortunately you've now given me another option to seriously consider, and "options" are my worst enemy for getting things done :P Thanks for the tip. I will have a closer look at his tree. I've calculated both 32 x 50 = 1600 pixels and 36 x 56 = 2016 pixels would require 3 outputs of the F16v2 (500-550 and 672 pixels per output respectively), and I plan to have a couple of spare strands of string, heeding the advice often given in this forum. :) This is one of the things swaying me towards sticking with 50 pixels per stand. But[i] if [/i]I were to settle on 56 pixels @ 3" (7.6cm) spacing I would request Ray Wu to construct the lights with 8-9cm centre-to-centre spacing (instead of 10cm) to reduce overall wire length by 10-20% which would hopefully reduce voltage drop enough to power the additional 6 pixels per strand successfully. Thanks for highlighting these additional points to be considered i13. The reason why I've already considered most of things is because you and others have helpfully pointed them out to others on this forum. :) [/QUOTE]

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