https://tube.loping.net/videos/watch/2ef52fd2-0ad8-42c4-84fa-1a486ffcc776 When we built and powered up the ALU for our 8-bit computer in the last video (https://youtu.be/S-3fXU3FZQc), it didn’t work properly. In this video we’ll try to get to the bottom of what’s going on. I got lucky that the problems were relatively easy to find. Sometimes troubleshooting can take a lot more time and be a lot more frustrating. But it’s also often where you learn the most. Sometimes you’ve just made a silly mistake (that you keep overlooking). Sometimes you get stuck because of some detail you don’t know about yet. It’s important to remember that unless you completely give up, you will eventually figure it out. There are a lot of resources out there to help you. Sometimes just taking a break and coming back to it a few days later with fresh eyes does wonders.
