Hi Guys, firstly can i say i LOVE the forum, LOADS of amazing help and advice and everybody seems so helpful.
I have a project that I'm trying to pull together, and was wondering if anyone could see a weak link that will fail or wont work and general advice on the project.
I need to create some free standing boxes, using WS2801 pixel strip LED tape (picture attached), (id also like some advice as to whether i would gain anything switching to the WS2811 chip) i managed quite well to get this all working using a mains power supply, now for the interesting part... i need it to run off batteries!!!
the idea is to run the unit from a battery big enough to have a run time of circa 6-8 hours running animations, here is the list so far that i have pulled together to try to get this to work
Battery

12V - 5V DC-DC converter

DMX controller

Wireless DMX receiver transmitter

I managed to get the whole system working correctly using the wireless DMX running the Chamsys software (which i know very well so will be my software of choice)
My question really relates to the battery side of the project, will the 12v with the DC-DC step down converter work? i was planning on using x2 for the strip, half the length off each converter, then i would power the DMX decoder direct from the 12v side and the Wireless DMX from one of the converters.
Sorry in the very long first post, any help would be greatly appreciated.
