That's not really a vicious circle. People not knowing you shouldn't prevent you from trying to do something. Do something cool and show it to an online community related to whatever you did, or even Hacker News or Reddit if it has general appeal. If it isn't cool enough to impress them, you'll generally at least get some feedback with which you can make your next attempt better. If you keep at it and care enough to improve, people will start to know you.
