When I first saw it, I was wondering why you needed 6 digets if it only does 1, but the scrolling display is a bonus! -

Sorry, I meant lines by rectangles XD -
dom2mom 22nd Nov 2012@BASSFREAK, since a lot of people dont seem to get the "no chain equations" What you could do is create an error message when mroe than 2 numbers, or one sign is added. This would be simple. You create 2 hollow rectangles. One has 3 pieces of swch in it, the other has 2. Every time a number is added, a swch is activated on the recantgle with 3 swch. Every time a sign is added, it activates a swch on the rectangle with 2 swch. If 3 numbers, or 2 signs are added, sprk from a battery goes is able to go through all the swch, which resets the screen, and types the letter E. (Or ERROR if you want, it is possible to type ERROR on you display) Hope this helps :). P.S. If you don't have enough time, ill make the circut for you. Its simple enough.

BASSFREAK 20th Nov 2012i checked the converter but its ok.The problem is the conection between the logic gates, but i dont find any mistakes there so it can take a while to fix it

BASSFREAK 20th Nov 2012yes i will try to fix the problem with the 5x7 calculation,i think its just the converter :)
