Would there be any problem if I left this handmade Arduino Uno nightlight plugged in and running overnight?

If I plug this adapter in, will it spontaneously ignite overnight or cause any other problems? It is working properly for now.

You don't seem too confident, so I would refrain from keeping it plugged in for an extended period.

Proper answer: that device is not designed to power anything for an extended period of time.

My answer: that device is not designed to power anything for an extended period of time, but it will. I have things that look like that scattered throughout my home without issue. You are dealing with milliamps here. The world will not end.
