I want to pimp / redo the project to a more advanced state and used circuito.io for the basic schemata of what I thought would be nice. Source: 9 months ago

I need to create a circuit diagram for my physics part of the architecture project I'm doing in university right now, and I found circuito.io which has nice looking circuit(realistic). The circuit is - Arduino Uno with breadboard connected, 5 capacitive touch sensors connected in parallel, each in series with an addressable LED strip (so 5 strips, 5 sensors in parallel I think).

Thanks you very much for the help! Btw one final question, I have done some fiddling with a web freeware called circuito.io and it says I need a rectifier diode. Does it serve the same purpose as a flyback diode as a google search indicates that the rectifier is to convert AC signals into DC? Thanks! Source: over 1 year ago

I put something together very similar to this, https://cmdchallenge.com that I like a bit better because it has console input. There is also a Christmas edition "12 days of shell" https://12days.cmdchallenge.com that is more like a learning progression. - Source: Hacker News / 9 months ago

Nice to see this posted on HN! A while back ago I used them for the design of a site a built https://cmdchallenge.com/ which gives it a nice feel of achievement badges without using standard unicode characters that may look different depending on the client. - Source: Hacker News / 10 months ago

Cmd challenge is a website that gives you a linux terminal, and asks you to perform different tasks on it, so you sharpen your linux terminal skills. - Source: dev.to / over 1 year ago

Aye that's a good one. CmdChallenge is also quite nice. Source: almost 2 years ago
