Circuit like in Figure 1 above show you about the 3V6/1W White LED Portable Solar Lantern Circuit. From Electroschematics site describe that this portable solar lantern circuit uses 6 volt/5 watt solar panels are now widely available. With the help of such a photo-voltaic panel we can construct an economical, simple but efficient and truly portable solar lantern unit. Next important component required is a high power (1watt) white LED module.

When solar panel is well exposed to sunlight, about 9 volt dc available from the panel can be used to recharge a 4.8 volt /600 mAh rated Ni-Cd batterypack. Here red LED (D2) functions as a charging process indicator with the help of resistor R1. Resistor R2 regulates the charging current flow to near 150mA.

Assuming a 4-5 hour sunlit day, the solar panel (150mA current set by the charge controller resistor R2) will pump about 600 – 750 mAh into the battery pack. When power switch S1 is turned on, dc supply from the Ni-Cd battery pack is extended to the white LED (D3). Resistor R3 determines the LED current. Capacitor C1 works as a buffer.

Engineering Book: Digital Systems Engineering 1st Edition by William J. Dally - Review and Free Download E-book

ElectronicKitSchool. - This is one of digital engineering book categorize that titled with Digital Systems Engineering 1st Edition that authored by William J. Dally  (Author), John W. Poulton (Author).

This article will show you the reviewing of Digital Systems Engineering 1st Edition like book description and review. The last in this article we also will give you link to take download e-book of Digital Systems Engineering 1st Edition by William J. Dally  (Author), John W. Poulton (Author) freely.

Overview

From Amazon describe that What makes some computers slow? What makes some digital systems operate reliably for years while others fail mysteriously every few hours? Why do some systems dissipate kilowatts while others operate off batteries? These questions of speed, reliability, and power are all determined by the system-level electrical design of a digital system. Digital Systems Engineering presents a comprehensive treatment of these topics. It combines a rigorous development of the fundamental principles in each area with down-to-earth examples of circuits and methods that work in practice. The book not only can serve as an undergraduate textbook, filling the gap between circuit design and logic design, but also can help practicing digital designers keep up with the speed and power of modern integrated circuits. The techniques described in this book, which were once used only in supercomputers, are now essential to the correct and efficient operation of any type of digital system.

Review

"Not many comprehensive references exist on this subject, and this book is one of the best available....Overall, this book will be a valuable addition to the library of every engineer involved in the design of digital systems, and for those who have only professional contact with digital system designers."

Standard Compact 2S LiPo Battery Charger Circuit

Electronic Kit School. - There are many electronic circuit that designed to result the best LiPo battery charger now. One circuit that can produce supply charger battery is shown look like in Figure 1 below. 

With the main or major component used are LM317 and TL431 IC, this circuit can be used to charge almost all standard 2S LiPo battery packs. The circuit, designed around generally available low-cost components, is very simple, safe, and economical.

Description

Circuit like in Figure 1 above show you about the Standard Compact 2S LiPo Battery Charger Circuit using LM317 IC and TL431 IC that give you one reference circuit to build by yourself of battery charger circuit that can be used to charge almost all standard 2S LiPo battery packs

From Electroschematics site that the typical target voltage of a 2S LiPo battery is usually 8.4 V (note that target voltage is not the same as the nominal voltage, which is 7.4 V typical), and LiPo batteries require a special type of charging mode that uses the CC/CV method (constant current/constant voltage) with 1-C charge grade (1 A for a 1,000-mAh battery). However, charging at a lower-than-1-C rate is perfectly safe and will not damage any battery type. The design is optimized for batteries of 1,000 mAh or higher, and the input power source can be any linear/switch-mode power supply capable of catering an output current of minimum 1,500 mA at 18 V. Normally, a LiPo battery connected to this circuit will be charged to 95% of its nominal voltage within 60 minutes and charged up to 100% of its target voltage within two hours thereafter.

Note: Although a balancer is required to maximize energy capability and lifetime of the LiPo battery, most chemistries have shown very little drift and are okay to charge without balancing for several cycles. I will try to publish an add-on LiPo balancer for my LiPo battery charger in the near future.
