I'm aware the title is rather unclear. Couldn't manage to formulate it correctly.

I actually found this question:

Half Bridge with dual powre supply and two N-channel Mosfets?

is similar to this one, which was asked previously:

Is it possible to build an H-Bridge with only N-MOSFETs (and these other components)?

So, naturally, I went to close it as duplicate, so we can vote, etc... Unfortunately, I forgot it, but I had already voted to close it (as unclear), before an edit was made to make it more clear (timeline). So I can't do it.

I really think it is a duplicate. Shouldn't the fact that the question has been edited be relevant, and allow me to cast a new "close as duplicate" vote, although I already casted a close vote before? I mean, the question wasn't formulated the same at that time, and the close reason is different.

Maybe this belongs to the main meta, as well. Not sure.


Community review is purposely designed to prevent any one user from dominating the process. Therefore, each user only gets to vote on a post just once.

Yes, that means that you'll sometimes get locked out in a situation like this. The most you can do at this point is to leave a comment that will guide other reviewers in the right direction. Or if you think it's urgent enough, raise a moderator flag on it and explain what the issue is.

  • \$\begingroup\$ Thanks. I guess I can accept the way it is designed. Not sure leaving a comment will have an effect, though, since it will probably be missed by everbody, this question now being a few weeks old. But, you are a moderator, so, if you agree with the duplicate judgment, you may want to fix that question eventually. \$\endgroup\$
