Thank guys for reply, I need it for the holidays so I guess I'll use corporal_clegg s method for now, without the switch as I can't leave my phone outdoor and then I'll come by to LJH's shop to make it for good, when it's open. Do I need this barrel fuse for now?
I'll be in your workshop every week Lao Jia Hou haha

Good to know about the market, but I don't even know what I should look for now.
