I respectfully disagree. I don't think it's wrong or useless to get an LLM to help, I recently did a similar project myself (even though I manually fact-checked all the high-voltage stuff).

If you find a guide that explains too much then you can skip the parts you know. If it doesn't explain something you don't know yet then you recursively look that stuff up. It doesn't matter if it's a book or a teacher or a search engine or an LLM.

It's just not good journalism here, because evidently this project has been done lots of times in similar circumstances without LLMs.
