Bumbling through a PDLC smart glass panel. I'll try and get a variac to see what happens varying the voltage.

Thought you was gonna have an electroboom moment there mate 😂
Hi David , you still have another clear protective layer of film to take off. Manufacturers have this on all Smartfilm products to protect the actual Smartfilm that is adheared to the glass. You need it on in the installation stage because you are essentially pushing it on with a felt tip applicator with can produce fine micro scratches whilst installing. On One side it protects the sticky side and the other side protects whilst installing. You'll find when you take it off how much more clearer it actually is.
no updates. dude is lame.
That 50 Hz hum was pretty impressive! The panel works like a large flat loudspeaker.
Had to rewind for this. That's terrifying :D
legit heard it and didn't notice it, felt like noise in the headphones but great spot
Used to work in an office with a meeting room with windows made of something similar to this. But they were crystal clear in one mode and totally obscured in the other mode. It was always a talking point for visitors. Horrendously expensive though when it was put in about 20 years ago. Great to see something similar available in the hobby market.
Gavin Smalley Yes, plus I was thinking that in a meeting room application the “not in use” state would presumably be transparent. So you would need to have power applied all the time, except when you wanted meeting privacy. So would ideally be the other way. ie. Transparent until you turned the power on!
Yes, it is expensive, I been quote around £600 per square metre... ouch.
I love technology, but I'm sort of thinking that it is a solution looking for a problem. What's wrong with blinds?
@@twotone3070you have to open and close all the blinds
David, are you sure that the switch is just a switch and nor also a capacitive dropper or something?
It seems to change from opaque to clear from the - side to + side in a sort of cascading (avalanche?) pattern. Pretty cool. I wonder what the voltage and current thresholds are?
I'm glad you bought that and not me !...interesting stuff mind you, cheers.
Ohh, always fancied one of those!
Is there any way that I can make a helmet with a plastic visor, but with PDLC over it, with a switch attached to the helmet side? I basically wanna make a tint on the helmet visor that makes the visor one way transparent and a switch to make completely transparent on both sides. Thanks!
When you were getting a tingle, the meter showed 47 and then 76, which is in the range for el wire. :thumbs up:
Why is it funnier when someone else gets shocked 😂😁
You asked and answered your own question😂👍
@@catherineharris4746 🤣🤣🤣
Thanks for tingling yourself so we don't have to!
I wonder if there's a protective film stuck on the panel to protect it from scratches during shipping. That might explain why it's not as clear as expected.
True, I do know peeling off it actually a sticker and ready to stick to the window, hope this helps.
yes is liner protective
is there any chance of making a little bit of this PDLS sheet in home? like a DIY project?
This would be useful for shop windows, where once your shop is closed you don't really want to tempt people with what they can see inside.
Thanks David, that's me famous now 😎 🤣 I think the samples I have are clearer when on, they were expensive (c.£400 for about 6 small squares) so I expect the material quality is high. It is a cool product, hope you find a good use for it.

Are those panels the same as the ones u find in a tv?
Does putting a piece of scotch tape on it bypass the opaqueness of it and let you see through it still like frosted glass?
4:30 Translucent would work xD!! Awesome content as always!!!!!
Crying, sorry for your pain, but the coffee that must have been spilt at 6:30.
Does it at least deter racons?
whats the name of the 70v battery pack that you used? checked ebay all over cant find it
I did my project from Xiaomi Mi Band 3 as SMARTGLASSES. Xiaomi Mi Band 3 has a specific build - doesn't have touchscreen but has touch panel separately. When you fix it to glasses or to your head by band you have access to HR tracking from superficial temporal artery , GPS tracking and more... My blueprints (3D print model) is on Turbo squid "Smart glasses Vitoculus from Xiaomi Mi Band3 3D"
lmaooooo@6:40 I needed that, thank you!!
hi i have on of them but it does not work when i plus it in and turn the swich nothing happens
I'd actually be really curious to see how that works over an LCD display.
Way to thick for a phone
Could this be made at home? The film its self?
06:34 not for the faint hearted. Keep watching for main voltage! Some google-results: "Smart Glass operates on standard line voltage". "Low voltage driving PDLC film: 24V"
Do you know if i can use this in a commercial product? Is it patented in a way where nobody can use it without a license?
Hello, do you think we could use PWM technology to make it slowly go opaque/transparent ?
I really want an answer to this
You just need to find a very small window to fit in to. :)
How do u make a big sheets
Put the COVER back on the Positive and the Negative David... So you are around to me more videos ....
May be AC is required to prevent metalised electroplating on the inside surfaces
I bet theres a protective film both side 🤔 thats why its still blurry
I wonder if the load was pulling down your EL wire power supply to the 1.x volts? It will be really interesting to see what power this draws, and what the minimum activation voltage level is. Also, if it is gradual or if there is a switching threshold (which I assume is more likely). Being like LCD you’d kinda expect minimal power usage though. 🤔
EL supply isn't good if it a high frequency is use, not very effective.
where did you get this film?
Interesting. Stay safe though eh? Gets a 👍 from me. 🇬🇧
polar filters makes it see-true ?
Hola, amigo podrías ayudarme!? Cómo hago para instalar lala conexión de este papel en una puerta corrediza!?
2:30 - well it's not a truth. If you look inside that switch you'll find PDLC film is connected in series with RC combo (R and C are in parallel) - RC elements values are set so the effective voltage you see on PDLC film is... 40 - 60 VAC depending on the sample. It's just the simpliest and the cheapest way to power this PDLC film sample. If you want to put PDLC on your window, big one, i'll need a dedicated power supply (i.e. with trafo and triac inside).
Can't cut for dimensions?
Can one play Bad Apple on such a display?
I got one of those, I thought 230V ac was too much and dangerous, it should have been anywhere between 15 to 72V ac, I have a pair of 30V ac transformer and put it in series, to give me 60V ac, that works fine. Thing need to test, what the current draw at 60V ac? and 230V ac?, it should be around 5W per square metre as far I could remember. If the wattage is higher, it might likely to burn quicker and shorter life cycle. I find there are a handful of helpful information on the internet. That something you can experiment on youtube. Have fun.
Practical application ideas? Kinda like an etch-a-sketch, i think.
Shower blinds? I mean, who doesn't want unregulated 240v around where they take a bath?
@@GeirEivindMork 🤣
first off, the red and black wire indicate DC... not AC. and I would bet that that little switch unit has some components in it.
It is AC, not a DC, David could test that too. black and red is the same as old main wiring.
agreed these need AC power
Oh thank god its not science rockets. I been having to to rocket surgery for too long to get involved in to science rockets.
Was waiting for someone else to catch it. Gave me a good laugh .
Good 👍🏻
cover those contacts bro
Can you cut it to a specific size?
Yes. This much I've worked out... I want to know if you can partially dim it to work as a visor in my car
omg what are you doing David. Please be careful lad :)
Do you think you can daisy chain a bunch of these panels?
you can get them made custom size, but yes you can also daisy chain them
Can you cut this to any shape?
yes, but can you vary the opacity?
Imagine having this in a bathroom
I need this in my vehicle lol
Did I see a kitemark stamped in the corner? Perhaps not.
lol
Nott gonna Lie, Yes I Laughed at You when you gott Zapped..
The word you need 4:26 "Translucent"
Wish I could be like David Watts. 😔
we sell it in mexico for only $390 usd sqm
Hmmm... I wonder is the voltage problem or frequency? If I remember correctly, el wire uses quite high frequency to drive.
Yep, not good with high frequency for the PDLC
@@emeraldbonsai It didn't have a transformer when it was sent to me even though it was shown in the photo off ebay. I got half of my money back.. if anyone bought one without a transformer can ask for money back if it did show on the photo. I wouldn't risk a shock unattended, for safety it should have a transformer with it.
@@emeraldbonsaiI am saying it is not suitable for PDLC
how many watts can David Watts dissipate while using a deathpter? Well, let's test him!
Apple introduces: iWindow
Yeah so we need to just DIY these things they are never going to get cheaper.
Bro you burned the multi-meter . It happened to me . People don’t measure 750+ v with multi-meter you gonna burn it .
yah... measuring AC voltage with DC was upsetting the power supply though, I think the multi meter is fine
_This video has 666 likes, is that trying to tell me something? Lol_
You look a bit like a natural born danger seeker!
The term is... its not rocket science Not its science rocket's
Are you sure? They certainly seem like rockets made of science
جرجر كثير يا نفر 😂😂 Lb lb lb 😂 Just short
Amateur.. Thinking you know better then the manufacturer regarding the voltage required..
