I want to make something like a 16x16 RGB LED matrix. I don't care too much about brightness or pitch. Sparkfun sells some 8x8s for $30. That's pretty spendy... You can buy individual LEDs for something like 3/$1 on Ebay - so that's cheaper. Any other ways to do this cheaply?

Thanks!

That looks pretty good! I wonder if I can find any smaller than that though... Now that I'm thinking about it I'd actually prefer a higher LED pitch than that.

You can use the PM (personal message) facility. That's what its for. ;) Click the pm button in one of js's posts.

If you think education is expensive, try ignorance.

Untill I "know" people I prefer PMs. So if you have a website I can look that up and then decide if I want to send an email.

I get some led displays from Ningbo in China from time to time. The have to be top quality of course, with guaranteed outputs from batch to batch.
