This solar charge control combines multiple features into a single design: 3A current rating, low dropout voltage (LDO), range of voltage adjustment (accommodates 6 & 12V lead-acid batteries), reverse polarity protection, low parts cost ($5.90) and low parts count (14 components). High performance is attributed to the...

The ADP1649 is a very compact, highly efficient, single white LED flash driver for high resolution camera phones that improves picture and video quality in low light environments. The LED driver maximizes efficiency over the entire battery voltage range to maximize the input power-to-LED power conversion and to minimize battery...

Here is presented a simple 500mA 4.1V or 4.2V Li-ion battery charger that is constructed with the MCP73826 linear charge management controller. There are two versions of this controller MCP73826-4.1 that is preset to a regulation voltage of 4.1V and MCP73826-4.2 with a preset of 4.2V.
The IC operates with input voltage between...

Long and longer timeout periods are frequent goals for the ubiquitous 555 timer. Generally, this is accomplished (albeit unreliably) by unusually large electrolytic timing capacitors. However, here the long period is accomplished by a more predictable ceramic or film capacitor and substantially reduced charging current. The...

LightUp is an interesting project that allows to build small electronic projects with ease and then use an interactive augmented-reality application to understand and visualise how the design works. Oh, how I wish we had this when we were kids!
They use components that are attached on a block with magnetic ends that are easy...

Accidentally connecting a battery reverse can be a real killer in electronic circuits. There are a number of ways to provide protection and all have the expected advantages and disadvantages. Any protection device connected in series with the battery reduces its voltage, and when the battery voltage is only in the order of 1.5...

You will discover that every electronics project has at least one schematic along with easy to read explanation on how it works. Also you can easily read the IC's datasheets using the links that are positioned at the bottom of the article. You can send us pictures with your finished and working circuit and we will publish them in the article giving you the credits.
