I started with circuit a couple of weeks ago and saw this one on a youtube video. I want to make this but I do not know how to pick the right MOSFET. I want to use a 3.7v battery and my device would only draw 40mA max. I would like an SMD mosfet but dont know how to pick.this is the video I got this from
