I live in the Philippines. Where can I buy a 1.5 volt miniature lamp? Simple Electric Generator HELP!?
Hi guys. I’m trying to make an improvised simple generator for my science project. We’ve been looking for 1.5 volt lamps around the Manila area but we’re not sure if its voltage is really 1.5. Where else can we find those types of low voltage lamps? We really need the 1.5 volt lamps. If you happen to know some other products (such as a camera, a toy, etc.) that contain such kind of bulbs, I’d appreciate it if you’ll add that info too.
And yeah, we have been debugging the project for two days. We tried to…
1.) Increase the number of turns of the #30 magnet wire (from 300 to 400) and
2.) get the coils closer to the spinning magnets by decreasing the dimensions of the box.
3.) We also made sure that the ends of the wire are fully stripped off of the enamel coating.
4.) The magnets that we’ve been using are strong enough and we’re sure about that.
5.) We tested it with a Sanwa Multitester under the DCV area set at either 0.25 or 0.1 and we saw the indicator moving in a back and forth motion at a tiny range whenever we turn the magnets. We assume that this could be the actual power itself?
6.) Does the size of the nail matter? Can a big nail get a share of the magnetism going on and therefore, might decrease the overall power of our magnets?
The experiment’s on this site:

The only modifications that we did were the dimensions of the box and the material we used to make the box (we used a cardboard illustration board); as well as the size of our nail, it’s not too big and it’s obviously not as small as the one being shown on the website but the rest are the exact materials that’s indicated on the site…
So our primary focus for debugging really is on the bulb. What do you think guys?
Thanks
Here is a source that has 9 questions. Scroll most of the way down to the bottom:

Other questions you might ask could be:
How does voltage vary with speed?
How does current vary with speed?
You could hypothesize that more turns of wire would produce more voltage, and you might even predict whether a doubling of the number of turns would double or quadruple the voltage. For this test, you might choose open-circuit voltage.
You could hypothesize the same questions regarding current.
how can i win the chief’s attention when he saw my project? i’d done a simple electric generator.(B.E 1-year)
I found my project very simple &based on principle. others had done based on application.
Electric generator useing a coil of wire?
James made a simple electric generator using a coil of wire. List 2 things that he can do to increase the current produced (output) in the coil
whats a science fair question for the ultra-simple electric generator project?
i’m trying 2 find a question for this science fair
dont get upset that u had done on principle base n other had done on application base.most imp think is that u had done that thing.U can explain principle n can say that by this way,one can easy explain this principle in the educ institute.
use it to drive a small DC motor and watch how the motor speed changes with the speed of the generator. Use it to power a small radio or i Pod. I used to have a radio and a hand cranked generator in my workshop in college, if the students wanted to listen to the radio during a practical class, one of then had to turn the generator, this taught them that energy was not free.
Electric generator science fair projects?
So I built an ultra-simple electric generator, and it lights a very very small bulb. The problem is, I need to find a new science project to go along with it. Please, does anybody have any ideas at all that I could use for this project? Any experiments I could do on this? Please, list as many ideas as possible!!!
