for the 7 segment displays, will there be any way to make them negative like how you could in v1? so we could use two's complement

you could always use a second display and just turn on the center segment...

i meant if there was going to be an update with a 7 seg display that had a negative symbol in it

If there were an update to the 7-seg display, I'd rather he added a dot, tbh, as that's pretty common IRL

thats fair

You’ll need to use a second 7-segment display for that. The solution for it that I came up with is a little convoluted but I can send you some pictures

sure thanks man

All of my circuits for the negative sign.

The Complete Assembly

All the individual drivers & displays wired together
BCD-
Handles the furthest negative sign.
BCD
This handles numerical values, as well as the negative sign.

You can use an led to create an 8-segment
