Generally it seems the consensus is: - make it obvious you are posting your own material (using phrases like "Show HN" or "I" in the title) and not try to hide that fact - provide insight into "how" you've done it or how you are doing. - don't do it more than once. Follow those and HN will not downvote you to oblivion.
