Gadget Freak Case #132: A Spiffy Face-Lift for An Old-Time Toy
Design News Staff -- Design News, January 4, 2009
Luis Fernando Espinal Ceballos of Colombia wanted to give his cousin's son the slot track racing set he loved as a child. But the toy seemed unbearably old-fashioned. So Luis jazzed it up with a new electronic control system. He dumped the old battery box and replaced it with a used PC power supply and rewired the entire system for tighter control. He also added a lap counter to the circuit and upgraded the cars from old Lotus models to new Porsche and BMW models.
