Clive Mitchell, or “Big Clive” is an electrician who lives on the Isle of Man. He has a love for electronics. He regularly disassembles working and broken electronic devices on his show, takes a picture of the PCB, reverse engineers them, then explains to you in detail how the circuit works, why it failed, how to fix it, and what to do to make it better.
Here he takes a luxory car ionizer to bits and explains how to modify the unit to work if you didn’t pay for the feature.
I’ve been watching Clive for years. I have a small amount of formal electronics training and watching him diagram this stuff is almost a guilty pleasure. I think I’ve learned more about circuit design from him than anything at school, give he’s had more of my time at this point :P
