Burning Sand: Logic mod and 6-bit adder with LCD

Using the Burning sand game's material editor, I created a system to make logic circuits on the pixel-scale. The final product of this mod was a "circuit" that added 6-bit binary numbers and displayed the decimal result on an "LCD" screen. I really haven't had any formal training in this area, so if any of my terminology is inaccurate or misused, forgive me.

Sorry I have another question, what is the best method for determining the layout of this logic? or am i going to have to sit down and figure out the if's and when's for every possible scenario? The smallest digit I'm sure i can work out fairly easily as only the values from the first, second, third and fourth can change this digits outcome. but as for the the next digit (the tens) i don't know where to start. Your advice is hugely appreciated.

@normskilight Read up on Karnaugh maps. I mapped out the circuit by making 12 individual Karnaugh maps for each of the outputs (3 digits times 4 bits per digit) based on the 6 input bits. This turned out to be a whole lot of charts, but I didn't think to do it in any systematic way. I just used brute logic. I got the boolean algebra from the maps and tried to simplify the circuit as much as possible by finding similarities in the 12 maps. There is probably a more elegant solution, though.

Thank you for making this video, I have a question regarding the "huge thing". (i have paused at 2:20)

I understand the three sections just before the displays that decode the 4 bit's in to 10 and then in to 7 segments. But could you please tell me what the portion (the L shaped potion on the left) is called that is fed by the adder (6 bits+carry) and outputs to the three lots of 4 bit.

I'd like to learn what this is called so i can learn how it works.

thanks in advance.

@normskilight The L-shaped circuit converts the binary number into a series of binary digits. It takes the 6-bit binary result of the adders and converts it into 3 "decimal" digits, one for each of the LCD displays. Each of these digits is actually in binary still, but the overall sum has been separated into three different numbers, each of which is 4 bits to represent the numbers 0-9. Does that make sense?

@samckledorf45 It does actualy and after asking that i slept on in and realised that if i first split the 6-bits three times i could extrapolate the decimal digits individualy from one another using three seperate decoders. I guess i was wondering if there were some mathimatical trick to obtaining the spliting of the digits, but i will just build my own decoders. Thanks for the response. I'm teaching myself all this as a hobby, so youtube has been indispensable, thanks again.

Have you tried Powder Toy, just google it, you can make so many things with it. Lots of electronics and logic gates, different types of silicone and everything. Plus loads of other non electronic stuff.
