About Max1811

The MAX1811 is a single-cell lithium-ion (Li+) battery charger that can be powered directly from a USB port or from an external supply up to 6.5V. It has a 0.5% overall battery regulation voltage accuracy to allow maximum utilization of the battery capacity.

The charger uses an internal FET to deliver up to 500mA charging current to the battery. The device can be configured for either a 4.1V or 4.2V battery. The MAX1811 is available in a small 1.4W thermally enhanced 8-pin SO package.

This amplifier is very easy to make and very compact, works with a single power source whose value can be between 4V and 12V.It is based on the use of a type LM386 amplifier, capable alone to issue a power of several hundreds of milliwatts to a load (HP) of 8 ohms, while consuming only a few mA at rest. Ideal for make a small portable battery powered amp.For an application in stereo, just to build this amp in two examplaires.

About LM386:

The LM386 is a power amplifier designed for use in low voltage consumer applications. The gain is internally set to 20 to
keep external part count low, but the addition of an external
resistor and capacitor between pins 1 and 8 will increase the
gain to any value from 20 to 200.
The inputs are ground referenced while the output automatically biases to one-half the supply voltage. The quiescent
power drain is only 24 milliwatts when operating from a 6 volt
supply, making the LM386 ideal for battery operation.

This simple circuit has five buttons and five LEDs. Four keys are linked with players, the fifth provides manual reset.

After switching on or after reset (reset, manual or automatic), all the LED off and the system is ready.

One of four players who were consigned to quickly see the button of its own LED light and all other keys are immediately blocked. The PCB file is provided in pdf format.

The hex code is also included in the downloadable project file.

So I made the pcb with eagle and I made it with the toner transfer method.

 

This project uses few parts, one microcontroller PIC16F84, one capacitor 100pf, one resistor 1k and one crystal 4MHz.

When for the first time would go turn on tester on the screen will appear message “TEST”.

A lot of it is accurate and now for now is doing great. I made it from magazine Emiter 6nr 2004 year, the PCB can be bought from the magazine is not expensive basic 3e a PCB for the display is 1 euro, and the magazine is 2euro.Autor of this great project ESR Meter is Blagoj Kupev.  More photos on Facebook Fan Page.

Adjusting the brightness of each group is provided by a generator whose frequency is fixed but whose duty cycle (temporal relationship between high and low) is variable, much more efficient than setting current variation in LEDs. It consists of a fixed frequency oscillator and variable duty cycle for each of three colors. Each oscillator operates independently, which helps determine the degree of brightness of each red, green and blue. For this project I made a  PCB using toner transfer method.
