Making a little DIY Amazon Echo-like device with a Raspberry Pi is a great project, but one of the downsides is that it requires a button to trigger the service to listen to you. Instructables user MisterM’s solution was to make that button an old telephone.
MisterM’s guide uses a British-style Trimphone, but with some messing around you can use his guide as a foundation for just about any retro phone as long as it has a built-in speaker.
As you’d probably expect, this takes a lot of finagling to get working, but the end result means you can pick up the phone handset, then ask Alexa whatever you want. Check out the video above for a full demo of how it works. It’s definitely on the ridiculous side of things, but it’s a fun little project nonetheless. Head over to Instructables for MisterM’s full guide.
