What is 100% free method to install HDP sandbox and start learning HDP?

[#1]

I have a laptop that has 4GB memory and can't try ambari owing to resource limitations. As per a tutorial from hortonworks I tried using Azure. In free trial I can't choose A4 sized virtual machine. This is only on paid basis. I would like to know is there a way to start learning HDP using hortonworks sandbox 100% free? Also, I think amazon EC2 is again on paid basis (.30 cents/hour I think)

As I could not find 100% free method including not able to use Azure as mentioned in tutorials, I bought a new laptop and started learning on my own

I had to buy a new laptop and install sandbox in it. This is the only way that I found as I could not find a free way to fix it
