I've considered doing something like that, but using one of the round "radial" heatsinks I've seen..

Is that a cyan LS/o?

Hey Wayne, have you checked out any "surplus" electronics stores? I have one near me that sells nearly every imaginable heatsink for about a dollar or three... They're used, but what's to wear out?

A suplus heatsink like the one in Yclo's post sells for about $2 locally.. The really big ones approach the 4 to 5 dollar range, which still isn't bad.

No offense YC, but unless you plan to use that sink for the upcoming 5-watt LS, I just wouldn't be able to get over the biplane look...

The heatsink was so cheap it's not funny. (purchased from Hong Kong)

It even had holes in it when I bought it!

I hooked up 4.5v and had it go up to about 1.1A and it didn't even get warm... (well it did but not noticably)

Now that's heatsink..

YES! Now we're talking heat sink! I have wanted to do that too, but I didn't want to spend the money on the heat sink. So I've just used aluminum stock, but I bet that thing really sinks the heat great!
