Giz publisher Danny was recently bemoaning the death of his beloved Roomba, having replaced it with a Dyson instead. At least when that model finally chokes, he could repurpose it as a go-kart.
Dyson engineers did just that as part of a challenge to use old spare Dyson parts and a Dyson motor to make Go-Karts. It’s fascinating to watch, both to see which bits of Dyson DNA you can spot in a given kart… and for the insane engineer riding one of the creations. [Core77 via Geekosystem]
