Electronics question: Where can I get big solder-padded perfboards?

[Jeff7]

Does such a thing exist?
Radio Shack has 2200 hole protoboards, but that's not big enough for what I'm working on. I'm looking for the things that have individual solder pads for each hole, with .1" hole spacing.
I'm talking about big boards, like maybe with over 5000 holes. Does such a thing exist, or am I just going to have to figure a way of attaching 2-4 of those Radio Shack boards?


Found sources. Mouser has some huge boards - 10x20"! I didn't know that boards like that were made. Jameco has a few as well. Thanks for the reminder that Mouser exists.

Have you checked Digikey and Mouser? What are you building?

Didn't think of those places; I'll have to try them. I've never bought at Digikey - their prices were always way more than I was used to paying. Mouser had decent component prices though; have to check them.

I'm putting together some quite sizable LED arrays. I've got a prototype running right now; going to see how it does over the next week. Fun little project - first I built DC voltage boosters to convert low-voltage DC to about 35VDC, to try to run strings of LED's in series, rather than parallel, to help prevent thermal runaway problems from cropping up, and destroying some of the lights.
Anyway, I'm trying to grow some plants inside, and there's just not enough window space left. We've got some prolific jade plants in the front window, and there really aren't sizable window sills elsewhere.
So these are going to be growlights - mostly red LED's, with a very small number of blue and UV LED's scattered among them. I'm finding that building my own is a LOT cheaper than buying commercial LED growlights would have been. And it's just a fun project.

What's wrong with multiple small boards? Use ribbon cable to connect them if it's all just going to be series straight across.
