So I learned something today – again.
I have been looking for 7-segment displays for the IRS panel.
I could not find the exact size for the digits. But from the pictures it appeared that the digits were a bit bigger than on the altitude panel.
I use 0.36″ on the altitude panel, so I needed something a bit bigger. So I ordered 4 x 4-digit 0.40 inch displays from Tayda Electronics. They arrived today, together with some white 0.36″ for the clock.
The north/south part needs 7 digits (1 letter and 6 digits). The east/west part needs 8 units (1 letter and 7 numbers). So you need unites like on the picture. And as you can see the 0.36″ units can merely be squeezed in to the frame. 0.40″ units… Forget it.
So not I am out looking for 15 x 0.36″ yellow displays.
