In the 1980s, a talking teddy bear called Teddy Ruxpin took the world by storm. Now, Oakland engineer Andrew Langley is bringing Teddy back. He hacked the bear’s circuitry and installed C.H.I.P., the $9 computer that his company, Next Thing, had just crowd-funded. The 1-GHz computer can run text-to-voice algorithms that let the bear read anything.
