Smart String Project 2012

can you say where you got them

[chrisatpsu]

some comparison

[chrisatpsu]

don't mind the wiring on the ss node in the picture, they wired it wrong. no wonder it was a bad pixel!

Ah... Good place to start. I recall someone on here saying coding was their thing. Hopefully I get my hardware skills going enough to work a little collaboration and come up with a high density board... Say 128 pixel? Of course I'm blindly assuming that a significant part of the cost is in the chip.

surprisingly, no the bigget cost would be...

coming up with a circuit board.  they aren't cheap! 

and the material (in quanitity) to encase the nodes to make them waterproof. it seems like it wouldn't cost a lot, but who going to make just one node

[chrisatpsu]

i think i can make better icycles than trying to splice wires on regular ss nodes.
that's one idea.

i have a nother idea that i'm not talking about just yet. (it has to do with my freestyle project)

and i want to experiment with single coor led controls as well
  of course i'm sure new ideas will come to mind as well.

Unfortunately, on my phone, so the chat room is read only mostly.

If the board is the largest cost, that actually gives me hope. I'm basically looking to put an entire string on a single board (I think the proper term might be a 128 pixel node) breaking it down, the cost might not be so bad. Same for the waterproofing, at least for the high density board. With everything being close together, it shouldn't take that much sealant.

[chrisatpsu]

well, the chips are surface mount...  soic-8, soic-14, and soic-16

[Slite]

Do you have a modelnumber of the various chips?

Wanna see if I can find them someplace... have a few ideas I want to fool around with as well...

First breadboard circuit works as a smart string node fully functional

Cool! good job.

Looks good Chris. 

Glad I could be of assistance.

Chris thanks for sharing.  I too was thinking about my wire frame animals but the cost of changing them over is crazy.  Most of them are still incandescent.  I check on the cost of moving them over to a solid color LED would and it was a few grand.

[mikedbom]

Thats pretty awesome Chris.  does the rainbow board provide the color changing or was that done over Pixelnet and the chip?  not sure if i saw that answer in the thread.
