After finished the second Mod.
I decided to make another one. It's simple one with no complicated components and it's much cheaper to build.
It has tactile switch + Mosfet, and it will cutout the power if lower than 3.5v.
With a 14500 battery, It can last a whole day for me.
Please give me any comments.
Then I will make 4-5 more of this model for my friends as a gift, here in Thailand.
Thank you for watching..
