There was this Kid... :) do a google search for "Nuclear Reactor Fusion Science Kid" and yes.. It was a DIY. I am not sure TH-cam would allow a DIY nuclear reactor. There have been 14 people who DIY'd their own nuclear reactor. (According to the article)
There's a difference between a homebrew nuclear reactor (which can be DIY if you're brave enough) and a nuclear power station. And hell - Michio Kaku built a particle accelerator in his garage when he was a kid. That's unconventional DIY but still DIY.
I've always dreamed of making electrical components and devices from scratch at home, and it's awesome that you're already doing it! Keep up the good work, Ben, it's really interesting and sometimes even inspiring!
I remember coating ITO slides with synthetic opal films in my undergrad, using electrophoretic deposition. I still have a couple of those coated slides because they're so pretty.
JiveFowl No clue seems I am missing a sputter gun, electron microscope, particle accelerator, xray machine collection, death ray, and many other fun toys. :(
Did you set out to make the LCD before building the sputtering chamber, UV exposure rig, etc., or did you build those things on their own and then one day realize, "hey, I have all the stuff I need to make an LCD from scratch"? Your videos never cease to inspire!
so this is what all those other projects have been working towards. this is awesome. and i like that you put the Lambda symbol from Half-Life on the LCD :D
Lol, I literally spent the night watching your videos, the fact that you just uploaded this one feels like "here, there's another one for ya, have fun" lol keep the good work Ben, you're our hero! Hope I can be like you one day
I like how it's all coming together and now you have a working LCD. Are you going to make the micro grid that would enable you to make actual pixel displays as well?
Hi Ben, I'm playing around with this myself. In the other LCD video you talk about using a mix of nematic and chiral liquid crystal to get the right characteristic, could you indicate what the composition of the mix was in this video, also did you use glass microbeads in the setup? Thanks.
Hi Ben, great video. I wonder, could you skip the photo resist step? Could you raster an electron beam to create a negatively charged image on the substrate and then sputter. Assuming the shutter gun produces positive particles, they would be attracted to the negative and form electrodes in the desired shape. With more than one sputter gun you could even dope the electrodes on the fly. I can think of reasons why this wouldn't work but i have no practical experience . Thanks for these great videos.
I love this whole subject of DIY and hand made electronic stuff! Do you think it possible to hand make a transistor ? The very first one looks very hand made.
WoW amazing, you have done a wonderful job, could you share with me a list of the machines (uv exposure, ...) and chemical products that were used to make this stunning LCD please ??? And if it's possible a PDF version of this video.
That's awesome Ben. Is it theoretically possible to make a color LCD stack by using 3 layers of slides? (You could probably make 6 colors then) Or would you have to put them side by side like an LCD monitor? Maybe you have to figure out backlighting first though...
Firstly, great educational video! I realize it might be a shot in the dark, but after seeing your video I'm thinking I can revive a faulty (leaking) lcd screen by replacing the liquid electrolyt between the glass plates. There are quite a lot of different mixtures for sale online, is there anything you could recommend? My LCD screen is from the early '90s.
Great video!. I have a silly question, in a LCD panel, is it possible to detach the TFT layer from the color filter layer (RGB) without compromise their integrity? I need to work with the TFT layer and its drivers, do not ask me why.
So, industrially, they have the pre-made parts like the reflector and polarizing filters, and they etch the ITO with traces going to the component leads? Great video!
that's really cool, do you have plans to make some multi-part displays, similar to the displays on a watch or a calculator, shapes you can independently toggle on and off?
Does black region (when display is turned on) blocks light in near infrared spectrum? Like from cheap IR LEDs. If so, I would consider building such a display for myself. Great video and tutorial! :)
Hi I am wondering what specific chemical you used for your liquid crystal? Also, what polymer layer did you coat it with before running it with the cloth? Thank you
Just interested in knowing how you are driving this display. I see a lot of info online that describes these as capacitive devices requiring a driver that pulses the electrodes at a given frequency, inverted signal between the common electrode and each “segment” electrode’s pulse. Also, I haven’t tried, but wondering how best to make contact with the metallic deposits on the glass. Is there a more permanent connection that can be made, like bond wires to the glass, and besides just taping them on, is there a more permanent way to bond wire to the glass? Can solder bond to the etched electrodes? Very interesting video to say the least! Thanks!
I noticed the absence of a step where you add 5 micron glass beads that you mentioned in your other video on Building a liquid crystal display. Did you not require them or just not mention this step here?
The gap is being controlled by the viscosity of the liquid crystal itself, and the amount of pressure that I applied to the stack. The uniformity and gap distance is not critical for a low-performance display like this. The glass beads allow much better manufacturing repeatability and tighter tolerances.
Well glass beads are required for efficient working. the display here was limping at slow speeds due to the absence of spacers. maintaining alignment layers (polyamide / PVA) at
You also mentioned a plastic film yet there is none. I guess as long as you have the alignment scratches in the conductive layer? I'm also wondering how you remove the photoresist once done.
I can't believe how simple this was! I have all that equipment just sitting around my house. I have a question....instead of the micron photoprocessing diode manipulator why didn't you just use a modified flux capacitor?
TIL: Mr. Krasnow is an engineer for Valve Software. I just thought this was a cool channel with awesome engineering projects designed to show us how things worked. Hey, Ben. Say "Hi!" to GabeN for me. Tell him I'll be up to see him just as soon as I finish my BSEE. I'm mostly joking of course, but who knows? I'd love to work there! :D
Hi Ben, I have a question for you, Do you think is possible to remove the color mask from a TFT IPS lcd in a "diy"home environment in order to obtain a gray-scale display, this question is related to lcd 3d resin printer, so if you have a gray-scale screen you can triple the resolution and the uv(400-415nm) light that passes trough a ordinary LCD to harden the resin, Thank you
First of all - great video! Just wanted to clarify though...so let's see -all you need are: Microscope Slides = $10 a pack Liquid Crystals = $5 - 10 (better question are you getting the right kind?) Acetone = $10 Ultrasonic Cleaner = $100- $200 Argon Welding gun = $5 -$15 (not sure if this is even the right tool) Vacuum Chamber = $100 - $150 Photo resist = $25 - $75 Ultraviolet exposure table = $100 - $250 Photo developer solution = $10 - $50 Etching Solution (Ferric Chloride?) = $25 - $30 Cloth = $1 -$5 Polarizer filters = $10-15 Or $406 to $820 to make your own LCD? Or, you could just buy LCDs from say ...someplace that sells LCDs?
great work, there is few passionated person who make videos like this. i liked your all tutorials. a great place to learn big things with working experiments. inspired from this video i also want to make my DIY custom display. but i am not getting that liquid crystals material. a big thanks to you if give me the link of that crystal.
this is great thanks and keep up the great work! have you seen Teenage Engineering - Pocket Operator Screens? They have some really fun uses of custom LCD displays this is great thanks for setting me off on more research
Wow 2013. I was curious if it's not viable to try to build "cheap lcd sheets" that would replace sheet rock in houses. From what I see here this is a 2-state lcd that only displays one image when it's on/off. To make individual blocks/pixels would be much harder/require what is it vector-something regarding the mapping of the pixels. Also I'm not sure that line from the half-life symbol (lambda?) if that is an "electric" line or if you just left that on there. So to make individual "pixels" (in the case of wall-sized probably 0.25" x 0.25" squares) you'd have to address those lines and machines can make them nearly invisible but human hands can't. I don't know just rambling. Thanks for the video. Still awesome to see the fundamentals that's where you start.
Hi *****, awesome work! Would it be possible to apply a similar process to build an elastic LCD display based on transparent plastic foil instead of glass? Or would the conductive structure break when the screen bends? I am talking about transparent foil like the ones used for printing. If not, do you have any suggestions on how to build an elastic display?
interesting work and educating video, I have a question about conducting coating, it seems a complicated process to built it but is there any way to repair a scratched conducting coating on an LCD screen glass on the edges where contacts are? thanks
I wonder how much current an ITO trace could carry? Would it be possible to power a small LED? I.e. etch a transparent circuit on the glass using the ITO, then glue SMD LED's to the circuit using conductive epoxy. Could make for a cool effect!
Late late LATE reply, but I was wondering if you could go into more detail on the Vacuum deposition process. Like what conductive vapor did you use, how long you had the slide in the vacuum, etc?
when you lets say have a finished square display and you would want to cute the square into different size pieces would that ruin everything if you split it? or can you make smaller versions out of larger pieces after by cutting it?
Dude. Who are you!? Seriously. The stuff you make usually isn't impossibly crazy, but I'm blown away how fast you make all of it! You do all of this, and still work at Valve??
Is there a more simplified way to make one of those without chemicals or radiation in a case with no air in it? I'm planning on making a singular 7-segment display card chip PCB thing. Basically it's a circuit board with wires leading directly to the screen with no micro controller. This setup can be sold to manufacturers to make the micro controller.
I think there is no need to buy or even produce conductively coated glass, because you can just use common window glass which is usually also coated with some metal to make it reflect IR radiation. Cheapest option would be to find some piece of broken glass packet and just visually inspect which glass has slightly reflective surface.
When going the sputtering, why not make make a "mask" or stencil to "shadow" the parts of the glass slide you did not want to coat in ITO? (like a crookes tube cross type thing) Is it because the edges would not come out sharp enough?
something you can easily do with the supplies from your nearest NASA parts provider
I love how people are saying this isn't DIY. DIY stands for 'Do It Yourself.' He did it himself, didn't he?
well then when a scientist builds a nuclear plant"himself" then its diy no i didint think so
A Lind Stay with me now, because I think I spotted a flaw in your argument: nuclear plants are built by *teams of engineers*.
I would like to meet the person who single handedly manages to accomplish that!

nice work, what is the liquid crystal you used in this video?
lcd has 3 letters the half life logo was on the lcd display... half life 3 confirmed.
What do you think - is it possible to use liquid crystals from commercial computer's LCD panels?
This is glorious!
When going the sputtering, why not make make a "mask" or stencil to "shadow" the parts of the glass slide you did not want to coat in ITO? (like a crookes tube cross type thing) Is it because the edges would not come out sharp enough?
Exactly, the lift off method doesn't work quite well with PVD
What material you used as sputtering , which etching solution you use to etching , photo resist was Positive or Negative ??????
Amazing! That is very clever!
How does one even come up with home brew LCD idea?... This is really really neat.
They can be set up small like pixels and accessed as nodes, but no color. Im going to try that thanks.
I have a question, what influence in speed of switching? voltage and area?
you worked at valve? whole new level of respect for you
Excellent video !!!! Thanks
