I am trying to create as many 74 logic chips as i can from my TTL cookbook. can i share the library once i have finished so other people designing a 74 logic based cpu can use my chips?
I've been working on this one for a while now. PONG!
I have more details in this thread: https://itch.io/t/4920753/pong-8-bit-computer
Seb, if you want to use any part of this for your program or videos, go ahead.
After playing around with your Buzzer chip, I got a general idea of how it works now.
Lowest note (0): A0 (27.5 Hz), Highest note (255): A#7 (3729.310092 Hz), each value steps up by 1/3 of a semitone (meaning 3 = A#0, 6 = B0, 9 = C0, and so on). The buzzer sound seems to be a simple square wave too...
This gives me an idea, which may take me a while to make...
Just downloaded it. Was very easy to setup, no tutorials needed. I have it set to display capture instead of application capture, but I'll likely switch to that. If I somehow forget, I can always just crop to the application window in post editing.
I also found a bug with OBS. Apparently if you hide OBS from capture, the Stop Recording button will bug out and only capture 1 to 5 seconds of video, even though I was recording for like 40 seconds. unchecking "hide OBS from capture" fixed that issue.
Your video quality is fine, it just takes a while for the higher quality part to finish processing.
For the XOR chip, you can actually make one using only 4 NAND chips: the first NAND is connected to both inputs, the second is connected to Input A and the output of the first NAND, the third is connected to Input B and the output of the first NAND, and the outputs of the second and third NAND chips go into the inputs of the final NAND, and the output of that is the final output.
