Experimenting with a liquid lens and driver IC

[the1cyrus]

any updates on this?

[mvakleko]

Do u think this could help ppl see one day or at least see better

[jimday666]

very informative. thanks

Would not work with crystal clear conductive membrane betwen liquids ?

A larger lens would be awesome, but judging by the pictures in your video it seems like the electrostatic forces determine the wetting angle, and then the meniscus is formed by surface tension forces. These forces would not be able to sustain a much larger meniscus. Anyway, I'm looking forward to your experiments :-)

The trouble with upscaling these kind of lenses is that gravity will overcome the initial surface tension and adhesion to the surfaces of the device.

The lens does work on small scales exactly how you explained, the power of these forces won't grow linear when you upscale the lens.

So in short: the laws of Physics are not in your favor when you try to upscale these devices.

Still: a really cool lens, nice stuff to play with, with a lot of potential!

To build your own lens, would it work if you separated the liquids by a thin diaphragm?

Ben's channel is my personal discovery channel :-)

I'm always looking forward to your videos!

Variable focus liquid lenses have been around for a long time -- in fact, I have two of them. So do you! :)

Very cool project -- of course the technical hurdles are nothing compared to the hurdles from the company, etc...

I have a few ideas for your larger porthole lens...

Peace!

Auto-adjust focus Glasses are neeed.

Eyes sight chanese over time. ( for some people 3 months)

So good luck with this.

There rae some glasses that focus already

This is interesting. watch?NR=1&v=Qe-lptJk5LA

Try pointing a laser through it.

[MrFraneque]

Great, man. Inspiring technology made easy. Thanks a lot!

[Landmarkemilestone]

Not knowing this tech on its place, i imagine its applications in Cyborg technologies. Think if one loses his/her iris, planting this in its place would give that person a new one, maybe an improved range, i wonder.

Some interesting stuff

[RasmusSE]

Incredible! How did you learn that that particular webcam used a liquid lens?

[Daggawaggaboof]

So many interesting things in your channel!

[abyssunderground]

Would be really interesting to see a lense the size of a window. Could you use it for privacy purposes instead of curtains, and just focus it when you want to see through it? Would that work or would it require focusing for each distance the other side of it too?

[Insignificantful]

This is so cool. How does that little chip turn the 5v from your Arduino into 60V AC?

[Kankki1]

Man, there's a lot of cool stuff I've never heard about :D

[mattvot]

I've found the same expensive developers kit with the eink screen industry.

[KiloSierraAlpha]

Very cool! Never heard of this stuff before. I wonder if Varioptic would sell you only the liquids needed to make the lens. ;)
