Happy to bring along some ideas and plenty of support. Can show off some wire frame stuff, controller box, etc. Will happily mock anyone with stupid questions.
My background is electronics and IT.
See you there

Have you thought about using 5v, only 5 power supplies. Injection is going to be easy, inject at the top.
50ma x 5120pixels = 256amps
256amps x 5volts = 1280watts
6 x 300watt power supplies = 1800 watts
1800watts at 70% usage would be = 1260watts
You could get away with 5 supplies.

You can simply cut the positive wire between the two power supplies at the 278th pixel, balance the load between the two power supplies. Check then check again, then get some one else to check.
Hi Tooms,
Happy to help out, can let you have this one from last year for $50.00 plus postage from Perth. I used a NB50 pole mounts nice and neat made from 6mm steel so it wont bend.
I used a piece of PVC waste pipe as a sleeve, then concreted it in place. My pole is a NB50 pipe about 3mm thick. 4M high with no guide wires. The base ring is high enough off the ground so I can get the lawn mower under the tree.

I'm in the middle of frantically rebuilding my tree from last year, this year I'll post some more details. I know a little late for this year but it may help those planning for next year.
