In the three years since Taras Kulakov started his wildly popular YouTube channel, Crazy Russian Hacker, he's uploaded more than 400 videos with nearly 800 million views.
According to this Tech Insider article, Kulakov started out in 2009 doing origami videos, transitioning to science experiments and DIY in 2012.
