1.5v to 50v step up

1.5V to 50v step up perfect circuit without ic
Needed
Inductor 220v-470v

220K resistor
100 k resistor
1 K resistor
2N3906 transistor
2N3904 transistor
1N4148 diode
Zener diode

Now the time for circuit design

Now you can able to do a step up circuit it can work 10 minutes only because 1.5v battery is weak.

EXPLAIN
Inductor use for

I dont like to use inductors. Mostly because I tend to stick to digital circuits. But I’ve used them sometimes for creating filters or oscillators. And that is what they are mostly used for. Filters and oscillators. You often find inductors in analog AC electronics such as radio equipment.

The inductor

An inductor is just a coil of wire around some kind of core. The core could be just air or it could be a magnet. When you apply a current through the inductor, a magnetic field is created around it. By using a magnetic core the magnetic field will be much much much stronger.

Inductor do

The inductor is similar to the opposite of a capacitor.
In series it will resist alternating currents and let direct currents flow free. It’s like a bully component. It will mess with the alternating currents. But the direct current he will let be.

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

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

How to make a poket radio(circuit)

Pocket radio diagram Needed BF 494 transistor  T1, T2. Variable resistor. Variable capacitor. Inductor coil. Lm 386 IC Follow this diagram and do it, Then follow the instruction :Initially connect the circuit as shown in the figure. :Connect the power supply to the circuit. :Now press the switch. :Now adjust the frequency of the circuit by varying the trim pot (variable capacitor) of the tank circuit. :Thus the circuit starts tuning to the nearest frequency. :When the frequency of incoming signal is matched sound can be heard through the headphone or speaker. :Now tune the circuit to the  another frequency using tank circuit. :You can listen another sound incoming at that particular frequency. :Adjust the variable resistor to increase or decrease the volume. Try and enjoy it
