In this episode of the O’Reilly Hardware Podcast, Jeff Bleiel and I speak with Niko Triulzi, co-founder and CTO of AE Dreams, the makers of the children’s product Turtle Mail, a wooden mailbox with a WiFi-connected thermal printer inside. Triulzi explains the hardware and software workings of the device, which enables parents, relatives, and friends to send a message from a computer or mobile device. The child then receives the message, which is printed from the mailbox.
