Mod Joycon jig Without welding.
Well what was said in the title, a mod for the joycon with a piece of silver paper 100% effective.
Step 1: Unmount the joycon and remove the pad (without breaking it).
Step 2: Under the pad are these pins, we have to join the marked in the image, for it we cut a piece of silver paper.
Step 3: We place the silver paper making contact between the two pins and place the pad on top.
Step 4: We check that the joycon works correctly before closing it (IMPORTANT to check first that it works in the system, if the bridge is done wrong, the console may not recognize the joycon).
If everything works well you just have to close the command and go.
