Ask HN: Good use of free $300 credit on Google Cloud Platform

By signing up, I got a $300 credit for Google Cloud platform that expires in 60 days. I plan to spend a small portion of it playing around with most of their cloud services. Looking for ideas to spend this free cloud power in the next 60 days and hopefully learn something new.. Not planning to spend it on bitcoin mining or anything of that sort. Making money is not the goal. Looking for something fun to create.
