Dave is looking to get his daughter a Polaroid type camera for Christmas. Leo says the Polaroid Pic is very popular and prints small business sized photos. The trick may be finding film, but instant cameras are coming back, so that may not be an issue. The film isn't cheap, however. Kids think they're fun. Leo says they're a great idea for teenagers.
Dave also wants to know how he could control his Christmas tree with the Philips Hue? Leo says that the Amazon Echo can control the Hue natively. SmartThings work really well with Echo so that's probably a good way to do it. The chatroom recommends the Wink Hub as well.
