a calculator

it took me 19 min i built a half adder and added a place for a capacitor in my full adder and the half adder

ok i did finish my project but why not make a pcb so i made one my first pcb btw and this is a full adder i think i still have to do more in the design or there is problems but for now this is enouth

after hours i finished the 8bit adder i am happy with what i achived now we wait for my last shipment to get reviewed so i ship this

it took me like 3 hours but i didn’t lapse all of it but still i finished it i don’t care about the time anymore i know i won’t get reviewed

tried to fix a problem fried the components and now i have to buy new ones and maybe some capacitors

• do i finish it as an 8 bit calculator or make it as a 4bit calculator?

finally finished on working on the project now the scary part testing
update: i found a lot of problems i will solve them tommorow i spent 5 hours today thats it no more

its a little bit messy but i finished 4 full adders and the half adder basicly half of the project

what do you think of my wiring? (these are just the inputs)

yes i hate soldering 2 hours and the results arent even 5% of the project so i will use breadboards again i took everything off

finally finished building the first prototype of the half adder it can do only 1+1 and 1-1 but i will make more connect them and it can do 225+225
15min building
1hour and 20 min debugging

finished on working on the build i will create in reel life(the photo is blurry i know)

a calculator with only logic gates that can add(16bits) subtract(16bits with negative) and multiply(8bit)
