There are groups all over the world with intimate knowledge of every thematic and regional issue working their brains & hearts out trying to effect change. Reinventing wheels is a luxury our living planet doesn't have the time for right now. If you feel strongly about one of the many ways our 'civilisation' is killing our common home, join up with a group you find congenial. The best action is one you can maintain over time, so find something you think you'll enjoy.

Tech isn't a cheap & easy shortcut unfortunately. It's already used with some sophistication all over the world. Attention is in short supply, and grabbing it tends to be expensive or risky. Personally I think Extinction Rebellion is on to something - they've done their empirical homework and are willing to take the necessary risks. But only time will tell.
