Jake's Clock Will Say Anything

Gadget Freak 175 Knock Clock 450px
Jake Rice can program his desk clock to display anything that comes off his computer. Rice turned to the ever-popular Arduino platform to create a multi-function clock display that presents time in Arabic numerals (hh:mm) and in binary (hh mm ss), as well as temperature in a two-digit readout with the degrees symbol. Since it runs off USB power through a USB to TTL adapter, the display could be programmed to display almost any data streamed from the host computer.
