ELEKTROBOOM

A man in a grey polo shirt sits at a white table in front of a window with closed blinds, initially holding a white cable and looking off-camera, then turns to face the camera while speaking, before the scene cuts to a close-up of a circuit board with wires and a multimeter, where he handles the wires, then the scene cuts again to a blurry shot of him in a different room, standing with his back to the camera, while the foreground shows a tangle of red, black, and white wires on the table.
