Think everyone else got it right here, they are designed for mining and mining alone. I think someone mentioned an engineer having the ability to disassemble it and use it for parts but I think that's about as far as you'll be able to get if you're thinking about other uses.
Well, if you are living in a very cold area then you could use the ASIC mining hardware to replace a heater. Plus you have the option to get paid Bitcoin or not while doing that.
ASIC's could also be used as a motor to power a small toy if you are interested in taking it a little bit further. You just need a battery to attach to it. I've also read that users on Bitcointalk have solar-powered mining devices that get paid as each day passes. With the proper wiring the ASIC mining rigs will be running on autopilot and you could introduce an Artificial Intelligence Chip to have the solar-powered system to run on its own and compute regular things quickly like math equations and even problem solve long questions.
Quantum Computer's aren't easy to obtain so these mining rig's compute the 3rd fastest.
