@TedW posted:Yup, and as we all know, there are square/rectangle “drumheads” also. My very unscientific measurement of 10 round ones and 4 “squareish” was 1/2” each. When I drew a close enough half inch circle and put four 3528 leds in there, I’m thinking that’s gonna be a lot of light. Would need to be dimmed down quite a bit to reduce or eliminate the glare. Resistors or something? Or use Nano/Pico/Z size led. Very difficult to work with… (click for larger image)
I don’t have a photo of the Lionel LED drumhead board I mentioned earlier in this thread, but I can tell you that it did not have square 3528 LEDs in it; instead they were much smaller rectangular surface mount ones - in shape more like a 5630 but smaller. (Come to think of it, they are about the same size and shape as standard “chip” size surface mount LEDs.)
I actually don’t find the pico or nano or even Z size LEDs I get from Evan Designs hard to work with BUT of course they come pre-wired. Trying to solder wires to LEDs this size is not something I attempt any more!
