Electrical work would be fun. I could install new lines to the panel and expand it myself. It could also be a fun side hustle to install 40 amps and connect to a 240-volt outlet in a home’s breaker box for those who want to charge their electric vehicles quickly.

I’ve also noticed an increase in DIY battery and solar setup projects. While you can purchase an EcoFlow with 200 Wh for around $200, building one yourself sounds interesting. I might experiment with a setup this year for fun.
