Systm: DIY Electroluminescence
>> David Calkins: Today's system is sponsored by Netflix, the United States Air Force, and Go Daddy dot com. Ever want to add little strips of light to your tech or backlight your photos to jazz them up a little bit? You know an iPod, PC case, or wedding photos? Well today we'll be looking at the amazing properties of electroluminescence and how to incorporate it into your gadgets and gear on today's Systm. ^m00:00:23 [ music ] ^m00:00:44 Welcome to the show, I'm David Calkins.
>> Dr. Kiki: And I'm Dr. Kiki.
>> David Calkins: Pat is on his annual vacation due to false imprison, so we've asked Dr. Kiki to swing on by and give us a hand on today's show.
>> Dr. Kiki: And luckily I have two, this is very exciting.
>> David Calkins: Can you give us a little clip?
>> Dr. Kiki: No.
>> David Calkins: I keep trying to get the clap from someone I just don't ...
>> Dr. Kiki: It's not gonna happen, sorry. So sorry to disappoint you. [ laughing ] Speaking of today's show, we've got electroluminescent sheets. This sounds really exciting, I am so excited about it but for the folks at home who aren't too familiar with this piece of technology - what the heck is electroluminescence?
>> David Calkins: Electroluminescence is a lot like a light bulb or an LED, it's just flat and it operates on AC rather than DC. So instead of screwing a light bulb into a socket, what you do is you connect a transformer to both the cathode and the anode, the positive and the negative, of your sheet and it glows because there's little charged luminescent plate there, and when it senses electricity passing through it, it glows bright green, bright pink, bright yellow, bright white, any color you want really.
>> Dr. Kiki: Yeah, and the reason it does that is that there's like a color vinyl over the top of it. So it's not that it's actually glowing that particular color, that they've got a coating over it that the light shines through and that's the color that you see.
>> David Calkins: And if you're looking for your own colors, you know you can always add what's called a gel - so actually most art supply stores carry what are called gels, but it's not like it's a bowl of jello, it's a thin translucent sheet of plastic like studio lights like we have here, will often have gels on them which is a thin sheet of plastic. So if you want your EL to shine bright red for instance, you just put a bright sheet of red on there and it'll be red.
>> Dr. Kiki: There you go. Or you can put like a solid vinyl over the top of it, they're like vinyl stickers that you can use and that'll block the light completely and that way you can have a design that is dark where the rest of the background ...
>> David Calkins: For instance t-shirts and things like that you'll often see EL shirts, EL hats and things that maybe have a heart on it or a puppy or a butterfly or whatever. And really it's actually a solid sheet of EL, it's just that there's a cover plate there so it's only letting the heart show through.
>> Dr. Kiki: Which makes it very pretty. Yeah, so make all this stuff, where do we get these materials? There are websites?
>> David Calkins: Websites all over the place. I happen to use electroluminescence dot com which is a company in Monterrey, but there's all sorts of different places you can go shop around as always, and when you're looking for things what you're really looking for are two different components. What you have is you have the EL sheet itself which comes in both a pre-cut sheet as well as cuttable sheets. We're gonna be working with the cuttable stuff so that we can make our own shapes and sizes and things like that. And then what's called an inverter, and what an inverter is, is quite simply just put batteries into it and it converts it from a low voltage DC signal to a very high voltage AC signal. And it's really easy to zap yourself, so you want to be careful when you're working with this stuff. It's not the kind of zap that makes you go ... on the ground or anything like that.
>> Dr. Kiki: It's shocking, it gets you and ...
>> David Calkins: And then you use the words that your mother always hated.
>> Dr. Kiki: Mother or father.
>> David Calkins: Mother or father, something. [ laughing ] It's ridiculously easy stuff to put together though, and that's what we're gonna be showing us today is how easy it is. It's just like screwing in a light bulb. You only thing you have to remember is that if you're putting it next to anything such as a person, a dog, or electronic components, you want to insulate it because it's gonna be very easy for you to zap your components with this AC current, and destroy any microchips you might have.
>> Dr. Kiki: That or also zap yourself while you're wearing it, say you made a costume or something. I actually had a friend who made himself a costume for burning man, and it was really this beautiful costume - fur and EL and it was glowing and all sorts of designs and he forgot to insulate the connection and every time he stepped it would hit against his skin and so he jumped a little bit. He was consistently ow ... ow ... ow. [ laughing ] It was pretty hilarious.
>> David Calkins: Now really, was that a bug or a feature? I mean it's burning man after all! [ laughing ] And the cost is really actually very inexpensive too, relatively speaking. Yes it is more expensive than a flashlight. So if you want a flashlight, you can get a flashlight for 5 bucks. This is more expensive so a good eight and a half by eleven sheet plus the appropriate inverter is gonna set you back about 40 or 50 bucks. So it's expensive but for ... one of the things we're gonna show you how to do is to make backlit photos. So when you're at a bus stop or bus shelter and you see these gorgeous, baby ads, or pick your favorite advertiser, and they're glowing, it's not because there's a light shining down on the advertisement, but it's because the actual advertisement is printed on transparent vellum and then it's glowing from behind - which basically makes it glow and very visible and you can see it from miles away.
>> Dr. Kiki: Yeah, and it does a really good job. I mean it's much better than having light like a neon or other light bulb placed behind those advertisements would be, shining out in these blocks of light. It actually gives it nice, solid glow so it's consistent throughout the entire image and you don't have light and dark spots.
>> David Calkins: They wouldn't be what's called a hot point which is basically, if you have a light shining on a thing basically you have a hot spot here and then it slowly gets lighter and lighter as it goes out. Here it's a very solid color all the way through, and if you're looking for a gift I mean, this is a really cool gift to give. If you're gonna give somebody a framed photo, anybody can frame a photo, it's very nice, but now using your home dot matrix or color laser printer, you can print off a super inexpensive sheet of vellum and then backlight that and now you have a glowing photo and nobody else is gonna be giving the bride and the groom like a glowing photo as a wedding present.
>> Dr. Kiki: Right, or the other project that you came up with was to deck out your gaming system.
>> David Calkins: Yes. As a gift to Patrick when he's released from false ... when he gets back from vacation, we're actually gonna make his ... gaming PC glowing so when he turns it on it's actually gonna glow, and we'll try to remember to insulate that so we don't blow up his CPU.
>> Dr. Kiki: That would be pretty smart, absolutely. ^m00:06:52 [ music ] ^m00:06:54

>> David Calkins: So putting together a EL sheet is pretty much the easiest thing in the world. It's not much different than screwing in a light bulb. Kiki, why don't you explain how the inverter works.
>> Dr. Kiki: Right, we've got inverter with triple A batteries on the inside - very simple set up. We stick the batteries in the way you normally would stick them into a flashlight, anything else like that, power button on this side on and off and inside here is a very tightly packed ...
>> David Calkins: Tightly packed.
>> Dr. Kiki: Some of the things we can't open it up because it might just spring forth and shoot all over the place, but we've got the inverter and driver inside of it. We also have, that comes out to the connectors which are the positive and the negative ends that you connect to the anode and the cathode on the EL sheet.
>> David Calkins: Here we have an uncut EL sheet and as you can see it is pretty much just, it's a sheet of plastic and what they do is on this clear sheet of plastic they slowly layer the conductors as well as the electroluminescent material. So basically the ... you can't really tell in TV land, but this is a very light green and on the back this is silver, and so this silver connector out here is the cathode and then because you can cut the sheet up on a regular basis, you have several anodes all the way around. So basically we can cut this sheet in half and if you have like a normal plug here, off on the bottom for instance, and you cut this sheet in half then this side would be wasted right?
>> Dr. Kiki: Right.
>> David Calkins: Well instead of doing that, basically it just has the second anode plug all the way around the whole sheet. So we can cut this up into tiny little segments. Now you might be saying, well do I need a special tool to cut this up into tiny little segments? We do have this special tool, we had to go out and buy it, it's a very, very special tool.
>> Dr. Kiki: Scissors. Very special.
>> David Calkins: Very special tool. Now ...
>> Dr. Kiki: I got to have my first pair of scissors in kindergarten, it was very exciting.
>> David Calkins: To turn it on and off, you can just hook up the alligator clips right onto a cathode and a anode, and that's a really good way for testing it. But once you're finally ready to go, once you've cut it to the size that you want and to use, it's a much better idea to solder two wires onto it. If you're gonna do this, do not use your 20 dollar Radio Shack soldering irons. If you remember from Patrick's iPhone episode, those 20 dollar soldering irons are pieces of crap. You want a really good temperature controlled soldering iron because it's very easy, because this is plastic that you're soldering onto, to actually burn a hole in the plastic and render the whole thing useless. So basically you want to solder it at 250 degrees Fahrenheit, and here you can see I'm just barely ... put any solder on it at all, but now I've got two good solder points - so now we can hook it up to, we can hook these hard wires up. And for those of you ... I mean it's really easy to cut. So basically if you want to cut this in half, it's really just ...
>> Dr. Kiki: Snip.
>> David Calkins: And that's all there is to cutting it in half. And to turn it on, really is just a matter of ...
>> Dr. Kiki: Want to do it?
>> David Calkins: And remember, it's really easy to zap yourself.
>> Dr. Kiki: Yeah, I'm gonna try not to. We'll hold it.
>> David Calkins: We hold it and we turn it on ... and you can see it's a nice bright blue. Now one of the interesting things is because you can have a small sheet or a large sheet, is the smaller the sheet the brighter the blue; the larger the sheet, the less. And basically that's just because it's sucking up voltage. So this has much fewer square inches than this sheet, so if I hooked up the same inverter to this sheet, it would be a much lighter color. It wouldn't be nearly as bright. And so basically for our studio, it's easier to show you how this looks because we have bright studio lights all around us, how bright the blue is with a small sheet than if I had tried to light up this whole sheet. This whole sheet does light up, but it's just not gonna be as bright. And of course you can buy many different voltages of inverters, like this particular one is really designed for something in the 4 inch by 6 inch sheet size.
>> Dr. Kiki: 12 volts too.
>> David Calkins: If you want something bigger for these sheets, they do have bigger inverters, so there's lots of different options you can buy. And of course there's all sorts of different colors, so this is that blue - green color which is very nice, very visible. You can also get a pure white color which is good for the photos, which is what we're gonna be showing you now - is how to backlight your photos. ^m00:12:29 [ music ] ^m00:12:31
>> We'd like to take a moment now for a short message from the U. S. Air Force.
>> John Wagner, the United States Air Force. I'm the commander of 45th launch support squadron. You know, I've always wanted to be a part of the space program and the Air Force is an exciting place to do just that. A lot of people don't realize the Air Force space program is equivalent to NASA in size and scope and in most cases larger. The shuttle launch is about once a month and I've got 3 launches here in the next 30 days, so if you want to be in the space program, the Air Force is a great way to do it. ^m00:13:03 [ music ] ^m00:13:07
>> David Calkins: I keep bringing this ...
>> Dr. Kiki: So now while David's playing around with that photo frame over there, we were playing with vellum and what he has done is printed a picture onto a sheet of vellum. Vellum's really neat because it's thin, it diffuses light really nicely, and you can print things on it. You can just stick it in the printer, you don't want to crease it too much or it will wrinkle and that diffuses the light differently; it's not what you want. What are you doing over there? What's going on?
>> David Calkins: Nothing.
>> Dr. Kiki: I didn't do it this time. [ laughing ] Nothing to do with the melting. But basically what we want to do is show you how easy it is to be able to create an EL photo that the light will shine through a printed photograph in a very even manner, so that it's really nice and pretty and you can stick it on your wall and it's nice.
>> David Calkins: So here's a normal photograph of me and my wife on our happy little day.
>> Dr. Kiki: It's nice.
>> David Calkins: Printed on vellum, so the thing with vellum is of course that if this were regular photographic paper, what would happen is that it would be opaque all the way through it. And it would look nice ... I mean if you want a framed photo. But if you want a photo which is actually translucent so that ... which we want, you print it on vellum and it's 10 bucks for 50 sheets, something like that in any size, and then behind the vellum what you're gonna do ... make sure this is on, keep losing contact.
>> Dr. Kiki: What you want to do is have your connections rigged up to the anode and the cathode and you don't want anything like a person's finger touching the anode. [ laughing ]
>> David Calkins: And so now ... what you can see here is, is I'm gonna turn this on and off so you can sort of see the difference in that. And we're in hot studio lights, so anything shot in this studio - for those of people who remember the ...
>> Dr. Kiki: Can I stick my finger in there and see if people can see the blue coming through and her dress in front there and around the back of their heads, but light, the colors, and the flame change a bit. So you might want to take the color of the EL that you're using into account.
>> David Calkins: And so we're actually using all green - blue EL. You can actually get white EL sheets, which is interesting, it has an interesting property. When it's turned off it's bright pink and it's interesting because as soon as you turn it on it becomes bright white. But here, it's good. You also want to select your pictures properly. So in this case, in a dark room, the flames actually appear to be like on fire; her dress is really glowing pretty. I picked this specific picture because of the contrast and because it has so much bright whites against a black background. And so, and that way ... I'm gonna turn this on and off, on and off so you can sort of see it.
>> Dr. Kiki: And you could do also, I mean this is the very simple incarnation of this. You could also put a circuit board into it and create a driver that turns on and off and oscillates ...
>> David Calkins: Absolutely. In fact, the company that I buy from, Electroluminescence Incorporated, they sell drivers and so basically it's an inverter and a driver at the same time. And then instead of having two contacts it has multiple contacts, so that basically you can cycle through. So when you see these like hearts where they'll slowly expand, what you're seeing is actually a driver which is cycling through A, B, C, D, A, B, C, and you can even program it so it can do tricky little things. ^m00:16:37 [ music ] ^m00:16:39
>> David Calkins: So here I've actually built a test plate for one of my walking androids, because we wanted one of the androids to glow, and so this is actually the normal chest plate - and I just cut this out of the electroluminescent sheet and then bent it to fit and if you actually look you can see that I bent around the edges here so that it's actually a 3D chest plate now. You can see the edges and so you lose a little bit of light where that fold is, but beyond that now if I'm orienting this properly against the robot ... this is actually how it would look sitting on the robot. And so you can do this to pep up, pretty much, any one of your projects whether it's humanoid, robot, or it's your personal PC, you could use this to under light a keyboard so long as you remember to insulate everything and you don't blow up your keyboard. And getting back to the, let's say we want to really kick up this robot. So one of the things we could do is, since we just happen to have a very nice laser cutter, is you could laser cut out some letters and things like that. ^m00:17:50 [ music ] ^m00:17:52
>> David Calkins: Here we've actually cut out the system letters, inverted, so basically what we're looking at is the back of our tape, our masking tape. It's not literal masking tape; here we're using actually gaff tape which is very nice, very black, very opaque. But you can use, like I said, just got to a store and stores always have pre-cut vinyl lettering that you can buy in different sizes. You could get it from tiny little letters this big to like 3 inch tall letters. And so now what we're gonna do ...
>> Dr. Kiki: Got the S?
>> David Calkins: Here I got the S, so ...
>> Dr. Kiki: From our show logo.
>> David Calkins: So I'm gonna ... carefully here put on our Systm logo, see if we can center this ... ^m00:18:34 We're gonna pick up all these letters, it's gonna be a little crooked. ^m00:18:39
>> Dr. Kiki: He shocked himself. [ laughing ] Ouch! [ laughing ]
>> David Calkins: Okay you don't want to do that, you really, really, really ...
>> Dr. Kiki: It might be a good idea while you're putting the lettering on, to not have your connections ... yeah and the inverter on.
>> David Calkins: It stings a little. [ laughter ]
>> Dr. Kiki: Lesson learned! ^m00:19:01
>> David Calkins: Yeah so we're totally doing this wrong, like we should be using a professional vinyl lettering but ...
>> Dr. Kiki: We didn't plan far enough ahead I guess.
>> David Calkins: Yeah, so ...
>> Dr. Kiki: And the S ... and I'll be the S! [ laughing ]
>> David Calkins: So here we have our system logo and now when we turn this on, what's gonna happen is, is the S-y-s-t-m will just be masked out and so in a really dark room, if we can get our lovely Swedish intern to turn off the lights once again.
>> Dr. Kiki: Yeah. So now ...
>> David Calkins: Again I have to apologize for the studio lights. It's very hard to see in the studio lights. If you're actually here, this is really bright.
>> Dr. Kiki: Yeah looks really great.
>> David Calkins: And by masking out just using tape, now we've got a nice little Systm logo on our little android. If you see a little red light, there's actually camera lights that you guys can't see but that's just the camera lights being reflected off of the clear plastic cover. But basically this is really bright, I mean this is as good as a flashlight. We just happen to be in a completely light masked studio, so it's hard for the cameras to pick all this up. But I could use this as a flashlight and walk around and see things.
>> Dr. Kiki: Well it's very similar to the backlighting of say, a cell phone.
>> David Calkins: Yeah so when you see those cheesy commercials with all the audience from a rock concert ... when the audience of a rock concert turns on their cell phones to light up because nobody's got a lighter anymore, it's the same kind of thing; in the same way that a bright room you can't see that light from the cell phone, you can't see it here, but this is actually a very bright light.
>> Dr. Kiki: It's pretty light, it's pretty bright, and ... as you can see when you're out there, all sorts of nighttime uses for it - maybe not so much in a brightly lit room, but necessarily outdoors for signs that you're making or if you want something that'll be nice on a wall somewhere, in a darker room or in a dimly lit area.
>> David Calkins: The nicest thing about EL sheets being a thin plastic is that you cut it with the scissors. You don't need anything really complicated at all. We just cut ours with the scissors to shape, and so basically in this case - so here's Patrick's super computer ... and we can just put little EL backing on and again because of our current environment, you're not gonna see very much out in TV land.
>> Dr. Kiki: But we'll see it and we'll like it.
>> David Calkins: But we'll see it and we'll take it, was really cool!
>> Dr. Kiki: That looked really neat! Okay.
>> David Calkins: So again if we can ... we'll turn off the studio lights and we'll see what you guys out in TV land can see. ^m00:21:43
>> Dr. Kiki: That looks nice actually.
>> David Calkins: So here you can actually see Patrick's day to day gaming computer and I'm just backlighting through the normal venting system, and you can see this looks really cool. So no matter what kind of computer you have, just adding a simple sheet of EL light gives you a very nice effect.
>> Dr. Kiki: Makes your computer fancy.
>> David Calkins: Makes your computer all fancy. And again, if you want your computer to glow bright red all you have to do is buy the white EL sheet, throw on a clear red gel, and ... do this. And you know, then it's gonna glow bright red.
>> Dr. Kiki: Yeah, or you could even get a number of different gels and make flames.
>> David Calkins: You can make flames; you can make whatever you want. And with the drivers that they sell, you can actually make those flames flicker.
>> Dr. Kiki: Yeah, you could - which would be really neat.
>> David Calkins: Which would be a really cool effect.
>> Dr. Kiki: A really neat effect. I'd like that, but I'm not a gamer and my computer is ... is solid.
>> David Calkins: I do want to reiterate though that when you're using this stuff, you want to test it out - like with Patrick's side panel for his computer, what I did is I just put it on, I didn't actually have the computer here. Once you figure out the pattern and you cut it to the size that you want, you really, really, really want to have some sort of plastic there so you're completely isolating the circuit because this AC circuit runs so high, at such a high voltage, that any computer chip it comes in touch with, it's gonna zap and that's the end of that. So if you've got like a 10,000 dollar gaming computer and you're not careful about insulating it, then your 50 dollar really cool light system will work just fine and your 10,000 dollar computer is gonna be utterly fried and it's gonna fry every component. So make absolute sure that when you put this stuff together, that it's insulated. I mean, it really does hurt. Like I said, it's not gonna kill you and like keep you up at night hurt, but it's kind of like when you're plugging in a light socket and your hands are all wet.
>> Dr. Kiki: You happen to stick your hand in the wrong place, and yeah. I could imagine though it would be ... it's something that a person would want to decide for themselves do they want to spend the 40 or 50 dollars and do they know what they're doing in order to insulate it and make their computer safe from what they're putting in, or do they want to spend a couple of extra hundred dollars on the gaming system when they initially order it? So it's up to you.
>> David Calkins: And if you happen to have a very nice versa laser kicking around, you can actually cut out really cool patterns on your EL sheet so you could actually have the flames cut out. So many options, so many things. So we ... at Systm we're not gonna walk you through every step of how to do absolutely everything, we just want to give you ideas. What would be cool is I'd like to see a whole lot of people make stuff with EL sheet, whether you're backlighting your computer, whether you're making a photo frame, and then send us pictures or videos - put it up on your Flickr account, put it up on your You Tube account, and send us links at Systm at Revision3 dot com, so that we can see what your projects are. Here we're not really an idea factory, we're sort of an idea warehouse and so we just throw out ideas and what we want you to do is just take these ideas and build stuff and send them back to us.
>> Dr. Kiki: Right so we can steal your ideas.
>> David Calkins: Right.
>> Dr. Kiki: No! [ laughing ] I'd love to see an American flag on a sweatshirt with like nice silver, like sparkles around the outside. I'm kidding. [ laughing ] No, maybe I do.
>> David Calkins: She likes sparkles. You could do ... and really the options are unlimited, so give us your best ideas, these were just some ideas that we threw out. The goal here was not to make a complete ... well technically the backlit frame is a completed project, something I'm gonna give my wife tonight and she'll go whoo! But you can do that with anything, so ...
>> Dr. Kiki: Yeah and you could also try completing it and wrapping it up in such a way so that you finish the connections a little more completely so that they're not just clips being stuck on and you're actually soldering in on, the wires get folded neatly in, and like we said insulated, and so it's nicely finished so that no one will get shocked in the very end product - and your wife will not be upset at you. [ laughing ]
>> David Calkins: So once again, it's very easy to - with a temperature soldering iron, just solder two little leads on here, and then you could actually, instead of using alligator clips you could clip off these ends and then attach these ends to these, or even just solder these actual leads on so you're clipping this off. And then insulate it again, if it's in a frame all you actually have to do is put the back of the frame on the, cover this plate up, and maybe tape this onto the back of the frame or something like that. And then you're done, and just as long as no contacts are exposed you're not gonna burn the house down, you're not gonna do anything. It's just you're gonna have a really nice little photo. This is a great gift, not just for your wife or your husband or something like that, but if there's a really cool photo of your friends or if your friend is a graphic artist - it doesn't have to be photos - it can be ...
>> Dr. Kiki: Logos or about anything.
>> David Calkins: Just about anything. And once it's backlit it's really cool. I want to see what you guys do with this stuff.
>> Dr. Kiki: I'd love to also. I think this is just, it's really, really cool technology and it's just so cool! Where can people go to get more information?
>> David Calkins: If you do a Google search for electroluminescence, you'll come up with a lot of different companies. I happen to buy from Electroluminescence hyphen Inc. dot com. They've got good prices, they tend to ship same day. It's not expensive but it's not cheap either, so it's one of those things that you've got lots of different options. ^m00:27:19 [ music ] ^m00:27:22
