This user is the PiEEG spammer on an alternate account. The GitHub links go to the pieeg-club account, the Youtube link goes to a pieeg account, the more information link in step 6 goes to the pieeg site. Nearly every submission from this user promotes PiEEG in some way even though the URLs go to different legitimate sites (turning on showdead is recommended): https://news.ycombinator.com/submitted?id=Christiangmer

He's built up a really impressive network of accounts and apparently the HN moderators haven't noticed him yet.
