Plenty of japanese people working at games companies in Vancouver . <| sep |> I feel bad that he made a point to ask you to come on this visit , when he knew how much missing your family would mean to you . Only to pull the silent treatment . You are a guest there and he isn ' t a teenager , I would be quite upset . <| sep |> Giving it a quick look over . The reverse polarty bit is entirely wrong , the resistor and diode need to be across the battery not the gate . gate direct connects . Not sure why you ' re using a mechanical switch and not a soft power option . Persnally i ' m not a fan of the whole arduino thing , they over simplify things which doesn ' t help you actually learn electronics . The wide 620 V rating is due to the voltage regulator they use , it ' s not great for a battery powered system . Something powered by batteries would require a good bit of engineering to get the off state draw low . Something like the MSP 430 might be better , need a better voltage regulator . This is a fairly complex circuit to design for battery powerered device . P . S . i really hate that schematic tool , it ' d be better to draw it up in like kicad .
