I started on a binary decoder this morning to hook up to a 7 segment display with a 0-9 decoder built on the back of it.

Iv known how to make a binary decoder with the help of AND gates for a week but it was two big for me to bother building till i got up and had a idea to put the binary above the redstone leading to the 0-9 decoder instead of runing 10 AND gates down the side of the binary switchs.

This worked kind of the same as a simple 0-9 decoder wich i then added later above the bonary decoder so it does it all in 1 space.

Thanks for reading and checking this out

Schematic up if you want it.
