How to simply store this energy?

How to store this energy for later use? Not expensive way  

Edit: Like charging my smartphone for example.

a battery?

I wonder how to connect this two oh course. Otherwise, duh man

Your name suggests we're gonna have reaally good time together

a bridge rectifer into the battery, or get a boost/buck converter if your fancy, but cardboard generator means your probably going the quick and easy route.

So this is basically an alternator that generates alternating current (AC), note the periodical dimming/flashing of the light. In this case the coil outside is the stator and the magnet inside is the rotor.

Because the direction of the current changes in AC electricity, you cannot directly store the power, rather indirectly by using an rectifier to convert AC to DC, then store it in a battery or capacitor.

I'm more curious about the part I store this constanly starting-ending energy stream to a battery without you know, damaging it or something. And what kind of things I need? Like to store the energy in a regular lithium cell, and to charge my phone what component should I use?

If you want to charge your phone, just use a normal usb boost converter.

 

Really i wouldn't mess with lithium batteries, they like to do boom if not monitored right.

 

What voltage and current does this make?

The design I'm planning to make is something more like linear motion, a coil wounded around an empty thin cylinder made of cardboard or something and a neodimium magnet inside attached to the both bases of the cylinder with eighter springs or elastic. While we move the cylinder we generate AC current and my project is to store that and use to charge my phone. Project dimensions goes something like cylinder magnet with 1,5cm diameter, 2-3cm height and free space of 10cm to wiggle for generating energy. My little knowledge of electrical engineering stuff is so much of a bottleneck for me that I would love if you helped in every possible part of this project

why not get a premade shake charger? They make these

 

How much voltage and current does this make? Id built a prototype to get this data or run the numbers.

There you go. Good luck.

Capacitor, not a battery for long term if I'm not totally wrong.

I have no idea man  And I'm probably not gonna find any of those shake chargers.

Replace the capacitor with a rectifier and battery combo. The rectifier to ensure you always convert AC to DC, regardless of the direction. The battery can then be charged by the DC output from rectifier. Use a nickel–metal hydride battery. It is safer and more resilient to intermittent charging.

For output, add a current-liming resistor and/or follow this page for a more reliable design.

the problem with shake generators is that they don't make much power, your not gonna charge you phone with it, or you gonna need to shake much longer than you will charge. The flashlights have low power leds, and your phone pulls 5-10w to charge.

Thank you soooo much sir :))) I'll follow this instructions for the rest of the project hopefully and it'll work.

My thinking is we'll have this notebook sized device in our backpacks and when we're walking all day we will have some juice at the end of the day, I don't know how little but hopefully an useable amount of energy. If doesn't work I'll make a flashlight out of it

yea your not getting enough energy that way, lots of people have tried it, and there isn't much energy to capture.

People tried this 2 years ago and failed. The energy generation is not enough to charge a phone.

If you want a realistic and operational means of power, you should look at projects like GravityLight and use DC generation instead.

That's probably not going to work. A phone needs quite some energy to work, and that energy's gotta come from somewhere. A backpack going up and down won't do it. You'd have to be jumping and running all over the place to generate enough power.

 

If you have a bicycle, you could use a bike alternator to charge your phone when you're riding it. Be warned though, a phone needs more energy than you'd think and that energy's gotta come from somewhere, which means you'll go a lot slower.
