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!
There was this Kid... :) do a google search for "Nuclear Reactor Fusion Science Kid" and yes.. It was a DIY. I am not sure RUclips 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.
Who would dislike this? It's impressive. By observing the work of individuals of our species who can DIY modern technologies in their garage, we can see how far humanity has truly come. Ben's channel inspires hope and ignites imagination.
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
JiveFowl No clue seems I am missing a sputter gun, electron microscope, particle accelerator, xray machine collection, death ray, and many other fun toys. :(
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.
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!
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.
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
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
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?
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??
Damnit, Ben! A lambda, in a circle, from a Valve-employee? It's mean, you tease! Anyway, I watched your tongue-device video, and I really have to say... It's intriguing. If one was able to make something like a laptop touch-pad, for the roof of your mouth (or the inside of your gums / teeth) it could be... brilliant for people with a wide array of handicaps and alike. Damned cool tech. I'll end this with the mandatory "Where's Half-Life 3?" - Look forward to more of your videos!
Not only you do freaking awesome DIY (where the "Y" actually means Ben Krasnow, lol!) projects, now you do a Half Life logo? ... I clicked like 100 times the subscribe button!
Wow that's nice a crisp, I'm surprised given the messyness of some of the earlier stuff in previous videos. I was expecting your first one to be kinda messy and then get an update video with a nice one...
I don't know if I would exactly call this DIY... Ok -- you can buy the glass with the coating pre-deposited so you don't need the ultrasonic washer or the vacuum chamber or the sputterer, but who the heck has photoresist, an ultraviolet exposure rig, developer solution, etching solution, and two polarizers just lying around the house. :-) Still -- very cool that you made this work. Impressive!
You can find the solution easily online with a quick search in an engine like Google. Say Amazon for example has plenty of solutions of both on sale, and various other sites have solutions available with a quick entering of the terms "etching solution" and "developer's solution" in a search engine request. Considering he also built the vacuum deposition chamber over time with parts be either bought or raw material he machined himself, that also counts as DIY I would say. The polarizers can be found in many products, from camera lenses to car mirrors, if you cannot buy it from an already assembled product, you can also research the material and how it is made and DIY, for photoresist you can either do a search in a shopping section to show you deals for it or search up what creates it and assemble the raw materials. The ultraviolet exposure rig can probably be built either using florescent lights, incandescent lights, or possibly LED's setup to UV panels to project light on an object to cure it which would probably run at least 700 mA at 12v or 8.4 watts for lower power projection unless you use higher power material. You can either build it or buy it, it's up to the person, but these things can be done but it would most likely take time and investment just like anything else in life.
I can get only silver or graphit spray to make glass conductive, but it won't be transparent. Is there an alternative solution to do it without sputtering?
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?
I'm starting to believe that the chemical vapor deposition process works better for curved substrates, and that that's why curved monitors are becoming so prevalent though few people want them. A curved substrate would act like a hood, and you would almost certain get better deposition.
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?
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.
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.
Have you thought about making your own vacuum tube? There are few things you need. Glass making skills and heaters and few specific materials for electrodes going through glass, oxide coated cathode and may be getter material. Everything else is quite simple if you are not going to produce penthode or octode with tiny wired electrodes that need to have small but certain distances from each other.
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.
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.
something you can easily do with the supplies from your nearest NASA parts provider
Very nice. That turned out much better than I was expecting.
i know I'm quite randomly asking but do anybody know of a good site to watch new series online ?
@Watson Corbin yup, I have been watching on FlixZone for since april myself =)

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!

This is engineering..
Yeah, pure engineering with no physics or chemistry knowledge behind it.

More for the knowledge of how it all came to be in the LCD world. A1 info 👍
Good contrast on the display. I wonder how much it would have been improved by using 5 micron balls as spacers.
Congratulation to final success and a well chosen pattern for it.
watching your videos makes me wish I had a garage and unlimited amounts of hours to toy with different experiments.
ianlinkcd you only have one life make the time and have fun or regret it later.
Really cool. And not too bad contrast either.
Lite svårt för oss vanliga dödliga att hänga med, bara. Som behållaren som han droppar "fotovätska" i. Ligger glaset/glasen i den behållaren, eller?
Han droppar flytande kristaller på en tunn glasskiva, som han har belagt med ett väldigt tunnt metalllager på.
you worked at valve? whole new level of respect for you
Awesome :) nice results too! Thanks for sharing! Next Oled :P
