Hello KEY5 friends, it's me again. I hope you're all in good health, amen. This time, I've come up with a very creative idea that not many people know about, and it's definitely very, very useful.

Materials:
18650 lithium battery
3S BMS

Filming location:
Narrow space in front of bedroom
Porch, someone else's house. I hope I can build my own house and studio

Filming equipment:
Phone camera (potato phone). If you want to take content, you have to delete the files first to have some memory left.
A tripod (bought on credit at Shopee)
Ecle headset (bought on credit at Shopee too)
Lighting: I used a broken LED TV with a cracked screen. If I bought it expensive, I'd just use secondhand stuff.

Partner:
A cup of black coffee but no cigarettes because I don't smoke
Snacks, if available, often none
Wife and 2 small children (when filming, I wait for them to sleep)
Don't forget to subscribe, like, and share.
THANK YOU
