The 100-yen "EASY SEALER" that fuses vinyl can be conveniently remodeled into LED and USB.

The 100 yen "Easy Sealer" that fuses vinyl can't be seen whether the heater is energized or not. So, I tried to visualize it using a two-color LED. At the same time, it has been remodeled so that it can also operate with a USB power supply.
It starts up quickly, is easier to handle than the remodeled soldering iron I made before, and seems to be convenient to use.
Paste the link of the self-made item that appeared in the video below.
I would be happy if you could see it together.
