Description
A simple decimal calculator. By putting cubes on two buttons, (the buttons are arranged like the numbers on a calculator), you can do simple addition and get a result between 3 and 17 displayed on the wall.

The mechanism is simple, but not too efficient. I just used OR gates for all of the possibilities (of which there are 36), except for numbers that can only be formed in one way (3, 4, 16 and 17), in which case I connected the buttons directly to the flip panels. This required 32 lasers and eleven relays. I've thought it over, and I really can't think of a simpler design. This probably won't be possible to implement into a puzzle as it is, as the mechanism, inputs and outputs require a total of about 1500 entities. Whatever, it's still pretty cool :)

Thanks! This is actually relatively simple to design (behind the scenes it's doing stuff like "if 6 and 1 are pressed, or 5 and 2 are pressed, or 4 and 3 are pressed, then output 7"), but it was fun to make and I'm glad you liked it :)

Minor Update: I just made a quick edit and published the map again, since it wasn't showing up in my queue. Thank you SO much for the latest update, Valve -_-

Ben is now working on fixing the NOT glitch.

@Geneosis: I'll try fiddling around and seeing if different things work. I know it's not the doors, though, as this happened with several other things.

@cyron43: Not trying to diminish Ben's effort at all. He's done an incredible job with this mod. It's just a bit annoying that I still have to use makeshift NOT gates instead of proper ones. And I was having this NOT gate problem even after update 1.02, so it hasn't been fixed yet. I've mentioned it to Ben, he'll take a look into it soon.

BTW Ben works really hard on it and by the fact that he released the second update already so short after the initial release is a clear sign we should visit the download site daily.

Cough BEEmod has been updated. V1.02 has the NOT gate fixed now. Cough

Well that's may only works if you set the door to "start closed"... Oh and I don't know if that changes anything but try to connect the inputs of the NOT gate before the outputs... But maybe the problem comes simply from the BEE Doors : I was able to remove a cube of a button linked to a door, and the door stayed opened... It seems that Doors are a bit glitchy when you command them quickly ^^"
