The reason I would suggest beginners start small and not jump to pixels is as already stated .. Sequencing
Most tend to do the same thing (I mean experienced blinky flashy not new people here ), yes we start early with planning , building , layouts etc but when it comes to sequencing it tends to get left till the last minute for various reasons.
My excuse for 2011 was that I just wasnt sure where all my newly built RGB items would be so how do I get that left to right fade or that rear to front fade.
My advantage was I already had multiple sequences that I could modify from 30 odd channels to 232 channels reasonably fast . 30 - 40 hours on average I consider fast.
For 2012 Im looking at building 2 pixel megatrees each one containing 24 strings of 42 pixels.
Do the maths thats 1008 pixels at 3 channels each = 3024 channels times 2 = 6048 channels that I need to program for 2 display items. If I get time Ill add in new arches with approx 960 pixels times 3 = 2880 channels. So now I need to add into my existing 232 channels another 8928 channels bringing me to 9160 channels.
Now imagine a newbie ( I hate that word) coming into the hobby. Wow look at that pixel tree that looks awesome and seems to be the way everyone is heading . Where do I start? What do I need?
Ohh cool I need a E68* or ecg-12pr controller and some pixels , sounds easy.
Ok great grab my wallet and pay $60 - $170 odd for my controller then visit Ray Wu and get a great deal and pick up 20 Pixel Strings for $550.
3 weeks later Im ready to rock
Ok so now all I need is pole a top ring and bottom ring and Im set to go .
Ohhh wait when I strung all my pixels up on my tree the wires broke from hanging them 12 foot in the air with no support.
OK lesson learned Ill just get some new ones. ( I cant solder well btw and have a very basic understanding of pixels )
Wallet out another $550
2 weeks later I get the replacements
Ok so some more research and find I need to have my lights supported by wire or strap.
Quick search I find a roll of 5/8 strapping for $40 from an overseas supplier .
6 weeks later it arrives
OK im all set . Ohh wait how do I terminate the strapping , ohh I need special clips . Quick search I find the guy who sells the strapping has the clips. Great order done.
6 weeks later order arrives . Ohh $#%$ wrong clips . After a week of emails supplier admits fault and the right clips are on the way.
6 weeks later im all set to start building . 2- 3 weeks later I have it its all built my first pixel tree.
Time for some testing . Geez this sequencing isnt so cool . It takes time and is quite tedious but I finally have some test sequences done.
Man that tree looks awesome .
July I have heaps of time so why not Arches look cool to . Another controller and some of that really cool digital strip ordered
8 - 12 weeks later I have my arches completed and tested its now October. Ohh #$#@ I better do those jobs my wife wanted done in May . I have plenty of time to sequence.
Late November arrives , ohh wow I need to set up my display .
Job done its now December and I still havnt programmed a full song.
If I search Vixen Forums Ill get some sequences to modify no problem at all .. Found 2 or 3 I like but they dont match my channel counts or layout , Spend 30 -50 hrs resequencing 1 song and slap a couple of wave meter songs in to fill the gaps.
Ohh this doesnt look so great , sequencing is too long and hard big dollars to expand lights . Think Ill just give it in.
This is obviously an exaggerated scenario but . I would rather advise someone to at least start small the first year. Even if they start with a Ren64 and only use 30 channels , at least they will get some understanding of what is involved with blinky flashy. Then have them spend mega dollars and quit the hobby because thay jumped in head first.
Im sure unless you happen to be in an area with someone like wjohn, ky , or fasteddy even a 30 channel display of standard leds will impress your neighbours and local area no end.
Yes we need a Pixel orientated wiki but most of the pixel related items are still newish to DIY and display items are still being nutted out. Sequencing is very long winded even in Vixen3.0 . Control boards are appearing left and right and new pixel strings are constantly appearing . Even with an extremely updated Wiki it still is not an area I would advise someone new to jump into.
Just my 2 cents
I have spent the last 3 -4 weeks just researching planning my mega trees . I have created profiles in both Vixen 2.1 and Vixen 3.0 and will being programming base patterns in both as Im not sure if Vixen 3 will have an E1.31 add in . I havent even ordered my controllers or pixels yet.
