Hardware Repair Educator at Gamepad Tester
Shows players how to use a test result to find and fix a fault themselves.
Thiago teaches controller repair. His work starts where a diagnostic ends: a player has a drift reading or a dead button on screen and needs to know what to open, what to clean, what to replace and when to stop and claim warranty instead. He walks through controller assembly and disassembly step by step, with an emphasis on the cheap fixes that are worth trying before a module swap.
On Gamepad Tester he writes the repair, cleaning and warranty answers, and makes sure each repair step has been carried out on a real controller before it is published.
