Do you have a point you want to make?

it is an open project for homemade generators where everybody can contribute.

details regarding the construction and observations are in the description of the movie "small generator 2 " on youtube - science toolbar channel

OK. I'm happy to discuss science, on this science discussion forum that we have here. I don't do YouTube movies.

No real world science dagnamit, only written descriptions of it!

 

Sorry, couldn't resist. :)

small generator homemade -"small generator" -  AC  generator - A diffrent approach
Things I used to create the generator in the movie:
 
3V Dc motor + plastic stalk ( inside “2 function toy” cars both parts; plastic stalk is used to fix the case of the toy car)
7w AC led light bulb+ E 27 socket  lead+ wires
3,7 v - 600 mah Li-Po battery ( mini drones) 
Neodymium magnet sphere diameter 12.7 mm + neodymium magnet screw thread ( just the metallic case needed – without the inside magnet)
Copper coil (inside microwave oven turntable motor)
Construction kit (toys) plastic and metal–used for the coil and the 3v dc motor holder
Power switch.
Important observations regarding "small generator":
1. the angle between the coil and the rotating sphere it is a must - like in the presented video -otherwise the output voltage will be low 
2. The position of the neodymium sphere magnet on the metallic case is a must-like in the video - otherwise the output voltage it will be low (“metal socket”)  N-S – I establish the position with a small iron screw.
3. I used nonmagnetic materials for the coil holder area otherwise the magnetic components will influence, in the bad way, the rotation of the sphere (like a magnetic brake+ the attraction force )
 
Observations: different types of DC motors, diffrent copper coils, diffrent batteries, diffrent neodymium magnets we obtained different voltages. RPM - important factor.
 
Note:
using magnetic sphere - 2 poles - high RPM nedeed for high voltage - like in the movie 
we will try to use more magnets on a sphere to obtain the same voltage at low RPM
also a liquied or a gas between the sphere and the coil can give a better "yield"
 
PS: we have 5 movies on the science toolbar channel all related.  
 
 "small generator 3" homemade project is looking forward for ideas to improve the small generator for educational purpose.
 
thx: science tools

I agree that it's an interesting science project. Basically a miniature DC to AC inverter. Is there anything here that is unique to this project that has not been done before?

"the metalic socket"  placed between the 2  poles of the sphere ( the  magnetic  force of the sphere strive to magnetize a metal in north or in the south pole )  which hold the sphere in the desired position ( betweenthe poles) at high RPM (gyroscopyc efect) , the position of the rotating sphere on the coil , (mentioned in this topic at "1. "and "2." ) - otherwise it will be just a ordinary dynamo and it will be imposible to light the bulb with the normal voltage.

 

Thx science toolbar.

How about including the costs of the materials used, just in case someone might be interested in playing around and wanted to budget for the project?

the materials are not so expensive. 

 

2 function car toy - 3 v dc motor and the plastic case holder and the power switch  - starting with 3,33 e (new)

 

a rechargeable Batery - phone batery, mini drone batery etc - starting with 4 e (new)

 

neodymyum sphere - 3 e - 14,44 e ( depends on the size) + neodymyum magnet screw - starting with 3.3 e (new)

 

small mechanical toy kit for the holder - starting with 2 euro (new)

 

coil - inside the turntable microwave motor - starting with 4 euro (new)

 

led bulb 7 w - 3 e 

 

socket E 27 - 2 e

 

medium average costs: 35 e

 

Warning!  we don' t recomand this project to persons  under 18 years  without specialized personal ( teachers, parents with :"entry level" knowledges about electricity).   The coil output  in the wright position (like in the movie "small generator 3 " is between 180 V Ac - 1500 V Ac (depends on the size of the neodymyum magnet sphere and RPM)

You think videos are real world science, apparently.

actually, the first ones :), science is every where.
wish to help us with the project ?

ps: with the video I've manage to go over the part with fake..., hided cables....,etc..and right know, we are in the second phase where everybody can contribute with ideas for the 3rd phase; more power for the small generator educational purpose. in our opinion is a collective science.

No I think real world science can be filmed.

I see you have also a video channel .  you wish to help us with ideas?

 

In 1774, Priestley repeated Scheele’s experiments using a 12-inch-wide glass "burning lens", he focused sunlight on a lump of reddish mercuric oxide in an inverted glass container. The gas emitted, he found, was "five or six times as good as common air." (1) In succeeding tests, it caused a flame to burn intensely and kept a mouse alive about four times as long as a similar quantity of air.

 

sometimes you can discover things more important then the researched one.

we have manage to list all the movies made untill now in a single place http://www.sciencetoolbar.com, we are looking forward for aplications of the magnetic flux generated by a spinning neodymyum sphere. In the future we will use more magnetic poles to obtain the same results at low RPMs

 

thanks st.

I assume that is a typo. You are not lighting a 75 W , 230 V Led bulb.

it is not a led bulb...... it is a 75 W 230 V bulb......

we are not losing time.....

time is precious....

2 coils 40 ohms each....

neodymyum sphere 30 mm 

Dc motor 4 V 

 

it is simple....

all is matter is the positionmetal case pot - sphere - between the poles.

 

thx st
