Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Jumperless: Breadboard Without Jumper
https://tinyurl.com/yr34sym6
https://wokwi.com/ is great for simple, digital only stuff.
https://fritzing.org/ will kind of lay out the PCB for you, but it's kind of a pain in the ass.
Wokwi and Fritzing are more "Breadboard Simulators" than real circuit simulators, but they do have their place.

Software for the arrangement of computer components on breadboards
Try https://fritzing.org/ for layout on breadboards.

My OR gate circuit isn’t working as expected, the LED should be turned off when both switches are off but it remained lit, what’s wrong?
Looks like fritzing

How to draw circuit with photos ?

is there an online tool that i can use to visualize raspberry pi gpio connections ?
Fritzing is open-source, so you can just download it from github: https://github.com/fritzing/fritzing-app and build it yourself. Might be worth a buck or two to download a pre-built version though...

double sided perfboard options
For designing them there are various tools out there. Personally I find https://easyeda.com/ and https://upverter.com/ easier to get started with. Other popular option (but with a much steeper learning curve) are kcad, but I have always found that to be clunky UI. https://fritzing.org/ is another local option that is easy to use but last time I tried it would crash on me all the time making it basically unusable - maybe it has improved since I last tried it.
- Hi, What software did they use to draw a schematic like in this picture?

Recommend an easy circuit sketching tool?
In the past, I have used fritzing.

Does anybody know what wbesite was used to do this ?

Sharing system RAM with video circuit ala Woz. I think I have a working timing circuit, but I now believe the EEPROM is too slow. u/gfoot360 how did you deal with contention on data bus caused by slow ROM?
My older design used shared RAM, again with separate buses and the ROM on the CPU side: https://github.com/gfoot/compvideo6502

Silly question: How do you do breadboard layout?
I used it for this project, among others - unfortunately the repository doesn't contain images of the layout, but I think it's there in Kicad format at least: https://github.com/gfoot/compvideo6502

Ben Eater VGA build, simplified... I didn't have a signal generator so, I decided to count in decimal from 0 to ten. Then run separate clocks to either the one, 10 and 100. It made it alot easier to detect the numbers needed.. now it's time to clean this up and move on.
Oh cool, glad you find the videos useful! I don't think this decimal idea came from me though - my favourite way to do this is using down-counters for timing, and up-counters for addresses. It eliminates most of the wiring, lets you use a compact memory layout, and sets you up well for things like split screens and hardware scrolling. It's also simple to configure the down-counters from registers so you can make everything software-selectable if you want to. See here for example: https://github.com/gfoot/compvideo6502

Interesting consequences of interfacing to nonstandard 6502 peripherals
It's what U19A and U19B are doing in this schematic, in the middle of page 7: https://github.com/gfoot/compvideo6502/blob/master/images/compvideo6502_schematic.pdf
