I would like to share the Component Skills and Circuit Protection section I recently discovered on EWskills.

I've been trying to get better at the practical side of electronics. Though I know the basics of identifying a few components, polarities of components and reading value of capacitors, resistors, I still felt there is so much I didn’t know. After going through some of these questions, that feeling was definitely confirmed. This is the most useful resource I could find for a more industry focused electronics hardware design skills.

Here the questions go beyond just identifying components. It has questions on markings, packages, datasheets, ratings and actual component selection.

The Circuit protection section has questions which forces you to think along the lines of what could go wrong, what protection you need, whether the component's rating is actually suitable, and whether the protection itself will interfere with normal operation.

Still working through the question and find them quite good.

I struggle more with the hardware side than software so I found this very helpful. Still working through the questions.

We have been working on a free browser based circuit simulation platform called EWsim.
The main goal was to bring mixed-signal simulation (analog + digital) and firmware execution for multiple MCUs together in browser

Current features:
-Supports Arduino, AVR, PIC and 8051
-supports Analog and digital simulations
-Build directly in the browser or load HEX files
-Multiple MCUs in one simulation
-Source-level debugging for AVR/Arduino
-Register, memory and disassembly views

When it comes to analog it mainly focuses on how a circuit behaves and works. It is not a SPICE-grade simulator.

The things we are still working on is ESP32 and ARM support with QEMU integration,script based custom modules and more sensor support.
Honestly I'd like to know if you have hit the wall with any of the online simulators if you've used them. Any questions, suggestions are welcomed.
