I've done a brief search through CSE, but found nothing too helpful. Are there any online resources that explain the meaning of the radicals followed by some examples in simplified Chinese?
I recommend mdbg.net's radical section. The first charachter on each individual radical's page is always the character the radical comes from followed by the radical itself (if they're different), followed by anywhere from a couple to several hundred charachters with that radical in simplified and traditional. Clicking on a charachter on any of the radical page takes you to the dictionary which shows the character in both simplified and traditional.
Hope this was helpful!
Try Zdic, just type and search. Content rich but entirely simplified Chinese.
