dude, i can't understand even a word of what ur saying

[raveeshakh]

I did not measure AC out put.The DC current was around 300 milli amperes and voltage was 4 volts.

[ImUrtastyflava]

Could you tell me what was you'r AC output and DC output from that rectifier?

[raveeshakh]

It is just a wooden plate with small holes (2mm diameter).I bought suitable spring pins to fit those holes.I connect the wires to the spring pins.I suggest u to buy one such board available in the market.This will save time.

[biguglytrux]

your circuit board is obviously homemade. i would like to know how to make it

[TributeToTesla]

fucking indians 

[hossamrida]

couldn't you just use a DC generator instead of generating AC and then converting it to DC?

[raveeshakh]

See, fundamentally a DC generator will have the same set up as this.Using coil and magnet, we can only produce alternating current which then will have to be converted to DC.

[hossamrida]

@raveeshakh I'll have to dissagree. As far as I know, we could use mechanical energy to rotate a coil in the magnetic field of the magnet and then instead of using 2 slip rings we use a commutator which enables the production of DC directly.

[raveeshakh]

true, what I meant when I said 'same set up' is that in my set up I have connected a rectifier system (bridge rectifier with four semiconductor diodes) shown in the video.This part converts Ac to DC. Slip ring could also be used.

[hossamrida]

@raveeshakh True. Anyway, thanks for posting the video, it is very helpful for students like me.

@hossamrida Spot on mate! You can make a simple Dc motor first with commutator, and then easily convert it to a DC generator. I'm doing this at Uni at the moment.

[eseleste]

this is a lot like mine though mine is poorly built and overloads often

[robotpredator8]

where did u get the han crank?u only turned it once but it moves so fast!!!

[raveeshakh]

true, it is a gear box from disposed Lorry.Its gear ratio is 1:35.

[raveeshakh]

bridge rectifier is used to convert Alternating current to Direct current

[allensree]

how / where can i get a dynamo????

will it be costly???

[raveeshakh]

the dynamo I have used is a bicycle dynamo available in any cycle vendor

[jesusmessanger]

this is way over complicated, just get a little moter out of a tape player or remote controle car and you dont need anything esle just somthing to spin the moter and two wires from the back end hooked to a light, or anything else you dont need a bridge rectifier
