We did this once at a traditional hackathon - we took a food dehydrator and wired up a temp sensor and raspberry pi, wrote PID controls and turned it into a 3D printer filament dryer.

I bet somewhere in Shenzhen you can actually have a hardware hackaton with an infinite supply of components and a PCB fab around the corner.

They should organize this and show us how it is done :)
