BlinkM alternative?

by joshstl79 on Fri Feb 13, 2009 3:30 pm

hi everybody. Sorry if this is a total n00b question...

anyway, so there's the BlinkM out there - the problem is, is that it's like $12... i know that's not a ton of cash or anything, but isn't there a way to slap together something home made? there are a few rgb led tutorials on the arduino playground, but still.

let the flaming commence, i guess...

Actually, there's a member here who makes and sells just that. It's called a ShiftBright, those are only $5, check it out:

Or yes, you could simply use 5mm RGB LEDs from Mouser or Digikey (or eBay, just don't get the "flashing" RGB kind!) and attach that to three digital output pins from the Arduino and by using PWM, you too can create all the colors of the rainbow :)

(Woo, 1000 posts!)

Whether something is "cheap" or not depends not only on the price, but the effort it will save you to get it working. BlinkM's are all set up nicely for you.

That said, you could looks at a ShiftBrite:

It's very similar to the BlinkM. The guy who designed/makes them, macegr, is active on the arduino forums, and often gives people who have bought ShiftBrites heaps of help.

i did get a little further than this but, as usual, when it got to the point that i could just sit there, drooling and stare at it for hours, the development effort suffered. it is scriptable. or can be controlled over the serial interface. it can run six different scripts simultaneously, but that hasn't been tested too rigorously. doesn't support hsv because i don't understand it.
