1) barcode scanner to put products in my online supermarket’s shopping cart 2) security cam to do facial recognition and drop me an email 3) general purpose remote control website/api for turning things on/off such as tv, amp, dac (typical things that need hw integration: ir blaster, 433mhz sockets, 12v trigger voltage etc). Recently discovered APIs integrate quite nicely with Apple’s iOS ‘Shortcuts’ app for poor man’s voice control!
