battery boost

Switching circuit without transistor and resistor

This is the perfect circuit for extra current switching.
its just a simple idea for boost current.

Now the time for see how to switch the switches.

6V=switch on S5
12V=switch on S1+S6
18V=switch on S1+S2+S7
24V=switch on S1+S2+S3+S4

Hiding voltages

9V=switch on S1+S5+S6
15V=switch on S1+S2+S6+S7
21V=switch on S1+S2+S3+S7+S4

100% working and safe circuit.

Alkaline battery

In an alkaline battery, the negative electrode is zinc and the positive electrode is manganese dioxide. The alkaline electrolyte of potassium hydroxide is not part of the reaction, only the zinc and manganese dioxide are consumed during discharge.

High power eneloop battery

One of the main features of eneloop is the higher voltage level. Many applications switch off or show the low battery signal if the voltage is lower than 1,1 Volt.  A traditional Ni-MH battery will lose its voltage constantly and runs under this critical level very soon. eneloop however will keep the voltage level over 1,1 Volt for a long time, and only just before becoming empty will fall under that limit. That’s one of the reasons why you can take more photos with eneloop

Eneloop vs evolta

This probably means nothing, but my personal experience with Panasonic NiMH cells has been outstanding. 3-5 years ago, I purchased a set of 1950mA AA cells with a charger from Costco. I believe that they are LSD cells before we even knew about the technology. I've had them in lights for 6+ months at a time and they work when I turn the light on. I've never owned any other cells prior to Eneloops that behaved like them.
Because of my experience with them, I'm inclined to think favorably of Panasonic cells.

Arduino colour sensor and servo pro

Colour sensor with servo project Making All we need for this project is one color sensor (TCS3200) and two hobbyist servo motors, which makes this project quite simple but yet very fun to build it. In the first place, using the Solidworks 3D modeling software I made the design of the color sorter and here’s its working principle Initially, the colored skittles which are held in the charger drop into the platform attached on the top servo motor.Then the servo motor rotates and brings the skittle to the color sensor which detects its color.After that the bottom servo motor rotates to the particular position and then the top servo motor rotates again till the skittle drop into the guide rail. Connecting method The code is below /* Arduino Project - Color Sorting Machine * * by Dejan Nedelkovski, www.HowToMechatronics.com * */ #include <Servo.h> #define S0 2 #define S1 3 #define S2 4 #define S3 5 #define sensorOut 6 Servo topServo; Servo b...

220v ac to 5v dc without transformer

220v ac to 5v dc converted circuit Needed 4*1N4007 diode 100 ohm 1W 470k 1W 225k/400v capasitor 470uf/100v capasitor 220ohm resistor 15v 1W diode led 10uf 25v capasitor 7805 ic 1uf 10v Now the time for circuit design This is the simplest way for converting 220 ac volts to 5v dc volts (usb current) it is use for mobile phone charger and power bank charger. Capasitor in this circuit for give smooth current. Diode in this circuit for convert ac to dc. (Diode bridge)   Capasitor in this circuit. Capacitors in DC Circuits. Capacitors do not play an important role in DC circuits because it is impossible for a steady current to flow across acapacitor. If an uncharged capacitor is connected across the terminals of a battery of voltage then a transient current flows as the capacitor plates charge up. Diode in this circuit for. Diodes can be used as rectifiers, signal limiters, voltage regulators, switches, signal modulators, sign...

how to fire a matchstrick wirelessly using android phone

Copper wire:0.5mm/1mm Copper wire:0.1-0.4mm Motor Arduino esp8266 12E 5v relay module Alkaline battery:5v-9v AA battery:3v Android phone Blynk application No worry about this circuit because this is 100% working and tested. The basic consept of this circuit is below This circuit is possible because mini copper wire get more heat than the bigger wire. Codeing method First you install arduino ide on your pc Then copy and paste this code in your arduino #define BLYNK_PRINT Serial    // Comment this out to disable prints and save space #include <ESP8266WiFi.h> #include <BlynkSimpleEsp8266.h> // You should get Auth Token in the Blynk App. // Go to the Project Settings (nut icon). char auth[] = "YourAuthToken"; // Your WiFi credentials. // Set password to "" for open networks. char ssid[] = "YourNetworkName"; char pass[] = "YourPassword"; void setup() {   Serial.begi...
