Technology: James May: The Reassembler, 9pm, BBC4

Hidden away in the BBC4 listings, this four-parter has seen James May (right) take a step away from his Grand Tour duties to look at the make-up of everyday items by pulling them apart and rebuilding them. If you have missed this show so far be sure to catch the final episode tonight, in which May looks at what makes a 1963 Dansette Bermuda portable record player tick – reassembling the 195 working parts.
