This isn’t the first time we’ve seen a Raspberry Pi used to add useful or entertaining features to a doorbell, but it’s probably the most feature-rich doorbell hack we’ve come across. Amongst other things, Ahmad Khattab’s Internet doorbell can call your phone, send you a text, and stream video of who’s at the door:
It’s a lovely DIY solution to the problem of missed calls and deliveries, and my favourite thing about it is imagining how much you’d pay for a glossy, boxed-up version of it. Ahmad’s costs £17 plus a Raspberry Pi.
Ahmad has written some instructions for the benefit of other people who are interested in better living through technology, but not interested in spending a lot of money on things in shiny plastic cases that you can’t open or customise.
