How to get a smart vending machine in your home

The idea for a smart-device vending machine has been around for decades, but the process of making one has proven to be tricky.

To make one, you need a small device that can take a phone call or send an SMS, which can also be plugged into a TV or monitor to turn the machine on.

And it’s tricky to assemble, since it requires a special software.

But with an open-source project called retrovac, you can build your own, and it’s now available to the public.
