Solar charging of batteries has recently become very popular. A solar cell's typical voltage is 0.7 V. Many panels have eight cells in series and are therefore capable of producing 5.6 V at most. This voltage is adequate for charging a single Li-ion battery, such as that used in cell phones, to 4.2 V with a buck or step-down charger. However, using the same panel to charge a multicell Li-ion battery like that used in laptop computers requires a boost or step-up charger. This paper identifies the key concerns in implementing such a modification and provides a design example that uses the Texas Instruments bq24650 solar battery charger.

The development platform for i.MX 6Quad from element14 (built to the Freescale SABRE Lite design) is an evaluation platform featuring the powerful i.MX 6Q, a multimedia application processor with Quad ARM Cortex-A9 cores at 1.2 GHz from Freescale Semiconductor.
This month, Freescale and element14 are giving away five such platforms, worth £128.06 each, for EETimes Europe's readers to win. The platform helps evaluate the rich set of peripherals and includes a 10/100/Gb Ethernet port, SATA-II, HDMI v1.4, LVDS, parallel RGB interface, touch screen interface, analog headphone/microphone, micro TF and SD card interface, USB, serial port, JTAG, camera interface, and input keys for Android.
And the winners are...
In our previous reader offer, Pico Technology was giving away one of its recently launched PicoScope 3207B, a 2-channel USB 3.0 oscilloscope worth 1451 Euros. Lucky winner Mr L. Sanchez-Gonzalez from Spain should be receiving his PicoScope 3207B soon. Let's wish them some interesting findings with his projects.
