Energy Efficient Torch

-
Hello guys!
This is a project of a energy efficient torch based on the principle of electromagnetic induction.
the pvc pipe is wounded with the copper coil and magnet is inserted into it, on shaking which induced an emf , and hence the emf is converted into dc and again filtered and stored in a 
Super Cap! and then the energy is used to light up an led,, 
it is in progress some 3d designs are in progress to make it look much cooler ;)  




P.S. a single shake of about 30 sec would generate enough energy to light the bulb for 20 mins approx!!!

Variable Bench power supply

 Hello guys!!  This is my variable bench power supply!! it gives an output from 1.24 v -28.4 v dc , a 12 volt output and a 29 v it is a switch mode supply which makes it lighter to carry , a 24 v smps is used as initial power supply then a lm317 based variable regulated supply circuit is added to it. Upgrades----> add a precise potentiometer  to get a precise output. P.S.-- this supply also gives a constant current supply for led  and battery charging!! Components Required:-  DC-AC Converter Voltage Regulator Enclosure Switches, Potentiometer, Connectors and Indicators Lets Start Building!! First Step:- We need to convert AC-DC for that we could use various things. if we want to make "linear" power supply, we need to use a transformer or a switch mode power supply(SMPS). There are variety of transformer available in market and of different shapes (toroidal or normal). To choose a transformer, first check out your require...

 Hello Friends! Today I would familiarize you with PCB-designed MSP-430 NANO. I have designed a low-cost PCB based on an MSP430-G2553 microcontroller supporting 20 pin DIP, s. Hence, would encourage and appreciate getting your own developed as well!!!                                                     (a) MSP 430   MSP-NANO, an ultra-low-power microcontroller, featuring 16-bit RISC CPU, constant generators, and 16-bit registers together contributing to maximum code  efficiency. The device goes from low power mode to high power mode within 1  µs as allowed by DSP, a digitally controlled oscillator.    Pin Description :      Details:  Low supply-voltage range 1.8V to 3.6V Ultra-low power consumption Active mode: 230 µA at 1 MHz, 2.2 V Standby mode: 0.5 µA Off mode (RAM retention): 0.1 µA Five pow...

Sand Casting

Hey Guys!! In this project i have tried to make my on fidget spinner using raw aluminium and cast it into the spinner frame!! NOTE--> DO NOT TRY THIS WITHOUT ADULT SUPERVISION (as there is lot of work and you would get bored if you do it alone😆😂 we started with building a mold out of sand , we used green sand for it! then melted the aluminium , do you know on melting the all the impurities from the metal gets separated . safely pouring the liquid aluminium inside the mold , use all safety precautions ,,, melted metal is very hot and dangerous. after pouring let it dry for some minute and then break the mold. not got what i wanted as the mold contains more moisture and it broke ,,, but got a custom keyring😁😂😆
