Day 8
I regret calling the day early yesterday. Contrary to my belief, timers aren't actually that hard. I made a D flip flop pretty quickly and flawlessly.
I learned to make the clock from the artworks page of CRUMB's Steam Community general discussions, turns out I need to supply positive current to the reset pin. (I really need to start to get into the habit of reading datasheets) I fiddled with it a bit after learning it to know how to change variables of the pulse timing (trigger capacitor changes the pulse delay, resistor connecting the discharge and threshold pin changes the speed of the pace of the pulse).
I then connected the clock to a delay timer, I also fiddled with it for the reason stated previously (resistor and capacitor changes the lifetime of the pulse). Then I connected the output of that to the AND gates of the inputs (replacing the enable). Ben Eater vid
To make up for my regret I tried making a JK flip flop, and was kinda successful! I luckily found this stackexchange post stating that the circuit shown in Ben Eater's video was wrong, (tl;dr he got it flipped) they also stated that JK flip flop was a junk circuit, but I'm too far into it to not ignore that. The thing with my circuit is that it works normally until both inputs are on. It does oscillate while the clock is pulses, but when the pulse ends, both are off. I actually got it to work like a real JK flip flop for a very short time but modified something in the circuit and returned to the previous state. I'll just blame the simulator like I always do hehe
I built all these circuits mostly all by myself again, I only read logic and circuit diagrams, no breadboard tutorials/videos which is a big win in my books! (except for the clock reset pin moment)
I think I'll take a break to research and decide what I'll do next, it's very possible that I'll begin to just follow Ben Eater's playlist. It's also to celebrate how consistent I've been, I've officially been doing this for a week!
