Hello guys, Im Saksham Prakash, 14, from Lucknow, India. In this post, I'll be showing you the audio amplifier, I made recently. The circuit is built on a perfboard which is fixed inside a cardboard box with the knob and other stuff sticking out. Some details are- IC- LM386 Wattage- 1/2 Watt Input Voltage- 6V-12V (I'm feeding 12V) Type- Mono (still working on stereo) Speakers- 2X 6 ohms 20W Song- She's like the wind - radio remix Here is the super simple schematic of the circuit- Some pics- Front view.. 3.5mm Jack (audio input) Output My two 6 ohms 20W speakers My 9V Battery. Finally the video- TURN YOUR BASS KNOBS TO FULL!!

Human body has an electrical resistance of about 1 Mega ohm. When our skin is dry, it can be more and when it is wet (from water or sweat etc) it can be lesser. This lie detector detects the resistance of our skin and plays a sound according to it. Lesser the resistance, higher the pitch of the sound played by the speaker. When we tell a lie, we feel nervous and sweat, therefore our resistance decreases which is shown by the increasing pitch of the sound from the speaker. A SCHEMATIC DIAGRAM OF THE CIRCUIT Sorry.. i had no perfboards left :) had to build it on a piece of cardboard. When the person is telling the truth. When the person is telling a lie.

My LED cube - 3X3X3.. arduino based. Hello people.. I'm Saksham Prakash from Lucknow, India. Recently I made a really simple LED cube which can display numbers, alphabets, patterns and designs etc.    The Arduino Micreocontroller The Cube 3X3X3 Random LED Program Program : int i; int a; void setup () {                                                                   for (i=4; i<14; i++){     pinMode(i, OUTPUT); } Serial.begin(9600); } void loop(){   digitalWrite (13, HIGH);   digitalWrite (2, HIGH);   digitalWrite (3, HIGH); ...

Hello people, I'm Saksham Prakash from Lucknow India. Recently I came up with an interesting but a bit dangerous idea of making bombs. So here I am with two of my best bombs.  They are filled with match heads and a thin wire  running between the match heads and connecting the two wires. When the two wires from the bomb are connected to a powerful battery (I used 12V 7.2Ah) the thin wire burns, igniting the match heads. Since the bomb is sealed from all sides, the bomb bursts making a loud noise. The Electronic BOMB!!! filled with MATCH-HEADS :P Another MATCH-HEAD BOMB! I also made an Electromagnet by coiling a wire around a screwdriver and connecting the ends to my battery. Electromagnet  Electromagnet Lifts a screw. Hope you like it. :)

hi people.. I am Saksham from Lucknow, India. This is my new darlington pair touch sensor made by me, using four NPN transistor BC-547 arranged on a breadboard. When we touch the "touch plate" a very little amount of current flows from our body to the base of the transistor. The two transistor amplify the current and light up the LED. Darlington pair touch circuit... LED lights up by touching the "touch plate"       a schematic of the circuit       only difference is that i'v used 4 transistors in this format
