How to Make Gravity Light | Gravity Lamp | dArtofScience

learn an easy way of "how to make a gravity light at home". This is a DIY Science experiment which can be tried at home or as a school project. A few months ago we had made a hand-cranked torch and since many parts were lying around, it occurred to me that we can make a gravity-based lamp too, that doesn't require someone cranking it.

you can put a counterweight to make a slower fall, and a bridge rectifier with a capacitor to have a more consistent lighting.

It's very good. But can we make that run for 5-10 minutes?

[MichelJosephCardin]

This is so thoughtful; this is absolutely ideal for where people are situated in secluded regions of the third world countries. this surely is the solution to their lack of

Try a gear train with extreme speed ratios and calibrate the system to attain maximum brightness and duration.
Very good project for energy enthusiasts!

[shubhigoyal]

Good. Using a motor with low RPM can increase the fall time. Also, you may put more weight accordingly.

Good morning sir,
With a friend we try to make a gravity light and we saw I you had succeeded. Would you be available to discuss this subject because several steps are causing us problems.
Thanks in advance

If you add a supercapacitor, you can store the charge, and the LED will run longer.

[arpitgupta]

Wonderful sir.. Sir I think you should also present the energy storing part.... In which the gemerator work as motor and raises the bottle up what you have done manually.

[ivanenergy]

Hello! Tell me please how the mechanism works when you lift the weight without turning the engine? And the window blinds mechanism still works the same ?

[Nag_ideas]

VERY NICE AND INFORMATIVE.. THANK YOU.
VERY WELL EXPLAINED

[vaishnavisavaram]

Are there any chances for making it an automated gravity lamp?

[sevi]

What are the specification of the motor you used? Can you please give me the link on where you ordered it?

[microtech]

It would be interesting to see it running continuosly up and down without human interference and could generate more power than it may consume.

[loupnoir]

Can you, please, give me the link to a site where I can buy the 12 V geared motor with shaft and the L.E.D. ?

[Skazzat]

very clever 5seconds light with gnagnagnagnagnagna sound, how I couldnt thought before ahhaha

[vincebenedicto]

What is the materials for the one with the window blinds?

[prasadm]

Hello sir it very nice .we have to generate electricity by manually than how can we make it automatically in advance version

[AsthaDalal]

Can you pls tell me all the components used here

[tanveershaikh]

Sir can you please tell us where can we get that pipe

[Thebansuriechoes]

How will the the gravity turn into electricity by the help of motor
