[edit] so my source claims he misquoted me and these are actually $15/m and not $10… still reasonable, but feel free to adjust lengths. sorry for any confusion. this is really not a bait and switch
I’m up for at least 5m, maybe more, and will drop you an email once I figure out how much I’d like.
It should be noted that the USB Client DP Module isn’t going to be able to power a ton of these LEDs - http://www.ghielectronics.com/catalog/product/280 says the module is good for “over 800mA” (which I assume is something less than 900mA) and the adafruit guide says these strips can pull up to 2A per meter with all the LEDs at full-white…
A Gadgeteer module like the DP one that could supply ‘normal’ power to the system but also with terminals for supplying power to side projects like this (or analog LED strips or steppers or whatever) is something I’ve wished for more than once… Having power plugged into just one place is a nice thing.
It would be easy to wire up some sort of single, split power supply for a DP module and a length of this strip. A simple pass through barrel jack with headers for the strip power on a perfboard would do the trick. It would be nice to have something in a single module, but in this case it would be pretty specialized.
At that price, I’d be willing to go for as much as 10m…I have some projects in mind that these would be great for, assuming I can figure out how to power them without burning out my board.
I can see why sourcing stuff is a PITA. Ah well, I’ll put up with the hassle for some good blinky. BTW - I got a meter to test, and it works as expected.
No idea who your source is but if they have API data for these strips, that’d be nice. All I could find is “write all bytes, every time” which seems like it could be a lot more efficient at longer lengths.
@ ddurant - no, i did a quick cut and paste of Adafruit’s code on an Uno. I will be trying yours, though, and will report back.
If you’re wondering what to do with this stuff, check this out. These university students got funding to do their senior project and put this in a local aquarium and environmental education center, http://www.echovermont.org/ .
You’re sure this is a digital strip and not an analog one, right? IE, you can set each LED individually instead of only being able to set the whole strip to a certain color?
