LG Optimus G Pro: Best of MWC 2013

One of the first things I noticed about the Optimus G Pro was how thin it was. Though this keeps it lightweight and sleek, it also made it slightly cumbersome to hold with one hand and navigate with my fingers. There were a lot of times when I used my thumb to click on something on the far right of the screen only to have the bottom part of my thumb accidentally select and open something on the right. It's still an attractive handset, however, and I think it's a step up from both the LG Intuition and the original Optimus G.

Propeller Clock-An Amazing Illusion

It was great to see a propeller clock circuit and its working.The great use of chips display the illusion of a clock in air with LEDs.

A motor spins the "propeller", and a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing to simulate a 7 by 30 array of LEDs. It is an illusion, but it works nicely.
