Diary:

ENTRY 1
Using CEDAR Logic to experiment with circuits.
ENTRY 2
Successfully built a 1 bit adder, copying to Powder Toy.
ENTRY 3
1 bit adder need precise timing so sparks can collide at XOR gate at the right rate, attempting to fix.
ENTRY 4
Fixed timing problem by using AC current instead of pulse, also making BASE2 to BASE10 and BASE2 to BASE10 easier.
ENTRY 5
Remove the top adder and part of the bottom for it is not used or required and effectively saves space meaning higher FPS.
ENTRY 6
Getting carried away with design, erasing key pads and display, starting over.
ENTRY 7
Completed new keypad and BASE10 to BASE2 converter, having trouble with converting back.
ENTRY 8
Sketching a BASE10 to BASE2 converter in my mind, using the outputted spark to change the direction of another spark and then using that spark as the BASE10.
ENTRY 9
Created BASE2 to BASE10 converter, planning to make display control unit later.
ENTRY 10
Finished, putting finishing touches on and publishing.

Addition of numbers that add up to any number over 18 will require modification to the key pad and display converter.

This is good. i gave a vote up (I always feel the need to say that)
most of the calculations worked, but when I selected a 3 and a 2, the answer was not correct (It wasn't a number)
I like your method.
Changing the Coal around the display to quartz made it a bit hard to easily see.

Thank you, I will fix the display converter in a moment.

I find your use of logic gates interesting. I can't seem to figure out how I might use one in a calculator without a lot of difficulties (And thinking). When I made my calculator I avoided logic gates.

I don't get what you have against logic gates, I think they allow expandability and improvement much better and you can simplify it or change it without changing the whole thing.

@Ace
Nicely done, reminds me a bit of my first calculator, mainly, what I think you need to try now is to shrink it down and add subtraction to it(it's really easy, just look up adder/subtracter schematic on Google images.)

I have plenty of (private) saves that have them in, I just don't use them for calculators

Good work :)

I've added some other display screens.
