81 LED Chaser Built With 2 555 Timers

[@Colin_Ames]

Great little project. Something I could build for my great grandkids.

Beaut project! I really like the way each LED lights up all the ones next to it.

[@Mad4400]

Brilliant project, even despite the distinct lack of echo/reverb.

[@lonesoulsurfer]

haha. there must be a way to add it...

[@mikebond6328]

Awesome!

[@jameslamb4573]

Perfect. Just what I need to mock up a starship control panel, well, part of it anyway. Would you mind if I took your design and modified it to use SMT LEDs with the controls in the rear, I'd like to get its size down a bit? Cheers

Knock yourself out! All the files are in the description link. It would def be a great little circuit to use in a starship control panel! Good luck with the build!

[@wmoecke]

and you might go ahead and try redesigning the circuit to use a single 556 chip (dual 555 in a chip), instead of 2x 555s for more size-cutting.

Fairy simple. 2*555 and 2*decade counters.

Nice case, only the four screws disturb the picture

[@lonesoulsurfer]

yeah - they pained me. I've sorted it though in the revised PCB

[@benjaminsapon1749]

need ur schematic diagram bro

[@lonesoulsurfer]

check out the link in the description to my Google Drive - there's one in there
