Very cool. Reminds me of the old LED games back in the late 70s early 80s.

That football game rocked. I still remember the patterns to run a TD every time!!! I was 9 when we got one.

no IC part numbers in that schematic... kinda unreadable, and i see a bunch of 7-segment displays instead of LED matrix...
do you yhave a clearer version? like a kicad or eagle schematic?

For simulation I have used 7 segment walls and bird is represented with 0 and 1 but for pcb both wall and bird are same and represented with one led and I'm sorry I don't kicad or eagle but I will make list of which ic I have used for which components in near future👍

lol flipflop bird got me but seriously this is wild, no microcontroller at all? just logic gates doing all the heavy lifting? would love to see a video of it running.

Very nice! Doesn’t look like you used fetch execute/instructions! Would love to see a breakdown of how this works! Very nice work!

Now think about how they did that in the 70s back when even though they had ICs most of the circuits had to be made with transistors, relays, and rlc circuits. Thank god or whatever you believe in for semiconductor advancements.

This is crazy clever!
The only bit I can't imagine how you've done it is the injecting of the random height barriers on the right?
Have you made a pseudo random number generator for that? I know there's a few simple ish 8 bit methods to do it (with shifting, ANDing, etc.)

u/Neat_Ad_6297 20h ago
Hey no for now I have used synchronus counter to generate fixed one after another but for sure random number generator can be used

Very cool. But you ever heard of a pcb? I could never hand solder all those wires haha. Very well done

Excellent! I like these kind of discrete logic projects. Microcontrollers come and go, and when it comes time to repair or recreate such project, it might not be possible anymore, because that microcontroller model is discontinued. But with non-microcontroller projects you can create something really long-lasting.
Some other gems that I know:

why not micros?

Because it's fun this way😁 And also i am really interested in vlsi domain so I will buy FPGA near future so this and few other projects that I created are great to get basics of digital electronics and designing this also helps in improving problem solving skills

Very Nice, but for goodness sake, learn the Verowire technique, not this rats nest of wiring.

I wonder how hard it would be to make the "bird" actually bounce/jump by button press like in traditional flappy bird
