i like it ! im looking for some kind of raster to mount leds on too.
Maybe spacing the digits a little bit further appart increases readability ?
Is this inside we are seeing ? otherwise it would read “OE” towards the outside.

My balcony rack is already perforated (as you see). That gave me the idea of created that LED matrix with digits.

Due to the cabling of each LED assembled by manufacter, I cannot separate them more. But I know what you mean. Maybe next year I will enlarge the cables of the relevant LEDs to give that space between each digit.

You got it, this video is mirrored because I recorded it on the balcony. Actually from inside you see “OE” and from outside “30”
My daughter already told me on 2nd Dec. :“hey dad, there’s an ‘S’ showing” :)).
