I'm looking for ideas... I need a big, highly visible, low power, seven segment display. Actually, two of them.
I want something at least three or four inches high, and it needs to be visible in direct sunlight or against a bright sky. LED *might* work but I'm not fully convinced - I'm thinking of those electromagnetic twisting shutter types but I have not yet found a supplier. Probably I don't know what to look for... any thoughts for such things in the UK?
