Built this on .net It's an 8 bit ripple carry adder

 

I used to be decent, I've made redstone creations for a few mods and once for a server.

Never made anything very impressive though, no screenies as I never tool any and deleted my world

 

I once did this with a giant board that displayed the numbers ;P
Fun times.

 

Yeah I was gonna build a decoder but it turned out that I didn't have enough space without destroying all my other circuits xD

 

/clone command bruh (y)

EDIT: I just realized as I scrolled up that you said you built it on .Net ;P
I build my stuff in creative mode... NEVERMIND xD
