[Gaurav Taneja] was showing off his projection clock add-on for iPhone called Clockety at this year’s Consumer Electronics Show. The concept is pretty neat, a clip-on clock which uses the iPhone flash LED as the light source. It may sound a little gimmicky until you see the functionality of the accompanying app which is shown off in the video after the break. Once clipped onto the phone, you lay it face down on your night stand and a gentle tap on the furniture will turn the projection on or off. This is a killer feature when you’re staying some place without an illuminated bedside clock.
Here you can see that the device is extremely simple, just a real-time-clock on a tiny PCB, a passthrough LCD, and the mouting pieces to hold the lens at the appropriate focal length. [Gaurav] has done a good job of pricing for the simplicity, with the Indiegogo pre-order price of $19.
At this point you use an SR44 cell to power the clock and LCD, with buttons to set minutes and hours. The optics have been designed with standard bedside table height and room ceiling height in mind, with a fine adjustment on the lens assembly for focus.
We really hope that this one succeeds because we have some ideas for the next revision. There should be a pass-through adapter that would allow you to charge the phone while driving the projector LCD. Adding power, moving to a dot-matrix LCD, and rolling in Bluetooth for v2 could allow you to push more data to the projected image. Or is that just overkill? Sometimes we get carried away.
