"Hi, I'm Jerri Ellsworth, and today we're gonna be making semiconductors with a toaster oven, a tea kettle, and toilet bowl rust remover. :)" This entire video is honestly incredible.

Anyone that doesn't get why rolling your own semiconductors is cool is probably watching the wrong part of KZread.

Years later this is still one of the most incredible videos I’ve ever seen

I first discovered your work because I'd seen homemade diodes and wondered about making transistors. "You can't make your own transistors" said all the detractors on everything that Google turned up. Then I found this cool American woman who'd been making her own for ages. :)

Why didn't we have teachers like you for chemistry and physics, not to say electronics? You are so clear in your explanations and totally without any BS.

I remember first time I watched this video when I was 11 years old, now I am watching it again. After living many things, trying and failing and maybe not even trying well and failing many things, now I see there is still something I love in this world. Noone will get it but only such things prevents me from suicide.

19 people thought the title said making Microwave Chips at home. lol

Very cool! I was looking at Sam Zeloof's recent videos and I wanted to learn more about the history of homemade chip fab. It's awesome that you were able to do this years ago with less equiptment

How come schools don't teach jack shit about electronics despite the fact that practically everything we use is electronic nowadays?

Because schools are out of date run by out of date people. Think about it children sit in a room from the age of 4 to 18. And if they are really good at that they go and sit in a bigger room for several years after. And after that the person is ready to go and get children sit them down in a room and control the whole room.

bighands69, i don't think that's the case, i think most people regardless of age or education realize that science and engineering is what drives progress forward, and electronics is a pretty accessible and practically important path. I think it's because they want to eradicate free thought and promote consumerism.

I think you are both right. They want to eradicate free thought and control people by raising them in a room

You're frickin astonishingly intelligent, creative AND funny at the same time. The cool scale doesn't go high enough to properly register your true potential. :-)

The good in building transistors at home is that you can do it and it stems the tide of "Gollums" pretending that science is a black art and only machines can produce "Tech". We need to keep in perspective that Humans create this stuff. Great Video as usual :)

I'm currently etching my own pcbs at home, and I'll look at through hole plating too. This is a completely new level you have opened me up to!

Hahaha. Did you mention ''common sense''.... On KZread? Seriously though I loved this - and what sort of numpty would complain or moan, its pure gold! ( also I knew it was magic when you said you dropped your wand)

This video has two of my favorite Jeri quotes: "getting tired of people claiming that my transistors are faked" and "before you get all preachy about hydrofluoric acid". Wicked!

I love when videos chain together to show something complex beginning with very simple things.

Jeri, you made my day ! I am also engineer and sometimes ideas like this are crossing my mind but I never tried. You actually did this. Keep up the good work and thanks for the videos.

Wow...I always dreamed of making my own microchips. I don't have the knowledge to design a circuit from zero, but at least now I know it can be done. Such a great video. Thanks Jeri and thanks internet :D

Agreed! This is a great video and proves what can be done by 1 person who is determined!

Thank you Jeri. I'd never thought about making chips at home, now I am. Very inspiring!

So impressive, Jeri! Thank you for the video.

I'm so glad someone is doing this! Gunna have to watch all these!

Wow. This is so brilliant that I don't know where to begin. Is there anything you cannot master in your home lab? You must seriously be one of the most talented persons alive on this planet. *speechless*

even just watching this video for half a second makes all your youtube suggested videos suddenly awesome

Wish I had a friend like you back in the day.

You are amazing Jeri. I accidentally stumbled upon your videos while sifting through various stem stuff available on KZread. I am very intrigued and impressed with how you got to where you are now :D The world needs more Jeri Ellsworth type ladies. Thank you for sharing your knowledge! I know this is an older video, but it is new to me since I have not seen anyone else doing this sort of thing on YT except you.

This is awesome -- creating microchips with Aquafina, rust remover, and a steam kettle. Great explanation, and as usual, it looks like you've found a way to get results for cents on the dollar. (Bus turn warning systems, anyone?) Thanks!

Jeri I have seen only two of your videos and I already love you.

You had me at 0:05. Apparently, I had been living under a rock before now. I admire your mind and I’m glad to know of you.

I know nearly nothing about electrical engineering, and yet I still find these videos interesting.

"My bones do feel a little gelatinous though.." :) :) I love it!! Super video, love the humor AND the science!!!

This is very refreshing! I have thought about making my own IC at some point but I haven't done it yet, this is great! I bought a thermal evaporator that I use to make condensor microphone diaphragms off of eBay, Something like that would be a perfect addition to your setup if you wanted to deposit metal interconnects.

Common sense is so rare these days it should be considered a fucking super power.

love your work!

We need more people like this, period.

Some people recognize that the skeptics and critics aren't the Teslas or the Newtons; and they often hold your work with no small amount of gratitude... perhaps even a hint of envy.. so thank you. :)

Wow, you impress me with your skills!

@ngneer999 I'm running oxidation for 6hrs. I have extra tubes for mine if I wanted to keep dopants separate. I don't at the moment.

Wow I’m wowed studied this 2years back just didn’t have the patience to look for this video This is sweet everything’s clearer now #Thanks

I came here to learn how semiconductors are made....since I teach new operators basic electrical theory at a commercial nuclear BWR and realized that I don't know how they make NPN (PNP) devices. I greatly appreciate your time and effort to teach these principles and your enthusiasm is contagious. Keep up the great work and let me know if you are interested in working in the nuclear industry.

Smart girl! Enjoy your videos, just stumbled over your videos... great job! Cheers from Germany

I thank you for sharing.

11 Years later and I'm just NOW seeing this? Still so very relevant.

I am glad you did not die - hope your gellatinous bones are better - excellent work as usual!

What is the difference between blue shirt jeri Ellsworth and the dotted short Jeri Ellsworth

Brilliant, I am going to use your technique. THANK YOU!

I love this. You're the Betty Crocker of Lithographic Engineering, Jeri. :) Excellent video!

The people who doubt you are just jealous of your awesomeness... Smile I think you fantastic...

you and Ben Krasnov are definitely my favourite 360º makers :D hadn't seen any of your videos for a while, and today I decided to randomly watch some. kick-ass, Jeri. my best regards u

You lady are my hero! A weird kind of hero, but a hero nonetheless. You have my biggest respect.

This is AMAZING. Thank you!

@Racius19 I get the wafers from ebay.

That is quite impressive.

Great Work. Thank you.

This is frelling awesome!

Nice demo. Many people don't realize that etching silicon is similar to etching PCBs. The hard part is growing the silicon cylinder and cutting it into wafers. That's where you need mult-million dollar fab plants.

thank you for the great video...your work is very much appreciated...thanks again

Wow ... very inspire ...

wowowow!! what a fantastic work! i love you!

Very cool!

Wow! Amazing. You are my new Heroine.

I like your mommy voice! YOUR AWESOME!

In the TLDR age of "let somebody else do it" you fucking rock!

Wow, I'd love to know some people like you You are awesome Thank you so much for sharing this with us :)

@bmdawe: if you have to ask "why", nobody will be able to explain it to you. @jeri: you rock beyond all limits.

Amazing 👏 Very inspirational, I will be taking notes 📝 🙂 Thank you 😊

Amazing!

I still find this awesome.

Congratulations excelent video!!! thank you

I love you !! You're my hero

Awesome!

You are amazing a genius, beautiful woman. I always thinking about what makes people very smart, but I don't see them anyway. But this lady have multiple knowledge about every aspect I can see that in her. This wonderful lady got specific unique look that indicates very high intelligence almost not Earthly.

common sense... is not too common these days. great work! love the video series.

you make me happy

Ima try to keep this saved. Thank you

Thanks for sharing, I was searching for the same from long time

Used to work with HF liquidfied and aq. It can be very dangerous depending on concentration and temperature. Been burned once or twice. You are taking very reasonable precautions (more than I would have probably). I've got to say that you doing what had to have been done in the lab in the development of this tech should not suprise anyone. Nor the fact that you are an attractive woman. The fact that you are doing it is just plain cool! I admire your inquisitive mind. You are rare.

THIS IS AWESOME

very good work

I love the aquafina plug in there.

I love your Video!!! : )

Thats amazing ladie

I am your big fan.

Hi Jeri! If you need new bones you can buy from ebay! Thanks for the video!

I really like seeing you in de reflection of the boiler. :-)

Jeri, carrying the fire.

FANTASTIC JOB !!!! Great Work !!! This is the start of great things for you! As an microcircuit enthusiast in Vancouver, Canada who has dabbled in a tiny bit of CPU/DSP circuit design, I've been looking for just such a KZread channel as yours! I have been eagerly looking for a way to do what you have just shown at home for many years. I've been itching for a way to not be so beholden to the wayward scheduling of our parent company's chip etching system. You have given me some incredible ideas and I think I just might be able to figure out a way to semi-automate SOME of your processes using home-built high-temperature-resistant 3D printers built from ink jet parts, ceramic and a do-it-yourself vacuum chamber! I think IT MIGHT BE POSSIBLE to dope the chips using a process similar to thin-film vapour deposition within a DIY vacuum chamber made from an old 20 lbs barbecue propane tank containing a TINY sealed printer head taken from an Epson or Canon inkjet. You will probably get a much more diffuse distribution of dopants using the nanoliter/picoliter capabilities of modern (and CHEAP!) inkjet heads! You might need to spend MAYBE $500 on parts and another 50 hours on assembly for the print head containing vacuum chamber. The SAME type of ink-ket technology could also be used as a DIY chip cleaning system within a SECOND propane tank vacuum chamber to spray solvents and/or specialty washes at nanolitre/picolitre amounts. For the chip masks, I suggest old large format ink jet printers you can buy off eBay for less than $1000. Just make sure their resolution is 600 dots per inch or better and PREFERABLY 1200 dots per inch or better. Print each layer of traces onto optically clear film using full black ink only! I suggest printing onto: ORAJET® 3352F Optical Clear Film from Orafol Corp or similar types of optically clear film. Print your traces and layers at 600 dpi or 1200 dpi at up 36 to 48 inches wide. Using such large prints for your traces means you can using a CHEAP DIY LED-based Infrared light array to expose the large film sheets into a CHEAP but truly optically clear high refractive index plastic focusing lens sourced from an optical supply store. You just need to build a large enough film-sheet holding frame (48 x 48 inches) and keep the plastic film electrostatically held onto a clear but very stiff 1/4 inch thick polycarbonate sheet embedded into the holding frame. The plastic-film-based printed trace sheets MUST be held on UNDERSIDE of stiff polycarbonate holding sheet to ensure less ragged trace edges when the Infrared exposure is reduced to micron levels. The large inkjet printed traces should then reduce quite nicely down to micron-level traces. It should be QUITE POSSIBLE to do two micron or even one micron circuit traces at enough accuracy that it is FEASIBLE to build a DIY 16-bit Intel 8086 CPU AT HOME !!! My estimate is around $1400 for the IR LED array parts, focusing lens and sheet filmholder parts and $100 electrostatic charger and the stiff polycarbonate sheet. So for much higher end performance chip making AT HOME, I think it's DEFINITELY feasible with around about $2500 and about 100-to150 hours of build time. Best Wishes and GREAT JOB !!!!

TotLy awsum your able to do this, wish we all were able.

Really Cool ! Fantastic , down to the atomic level kind of person. It would also be great to have some superconductor recipes in the future Jeri :)

all respect for you nothing less.

I am working in a mass spectrometry lab (maintenance technician) and one day I was surprised (i did not had mauch experience back then) when dichloromethane actually penetrated through the nitrile gloves while degreasing some parts of accidentally 'oiled' instrument components. :)

this is nice!

AWESOME!!!!!!

this person is awesome

great work i like to do things my self as well.

you are awesome.

Keep going Jeri! And don't pay attention to those goofballs who think you're faking your transistors. I know better!!!!

You are awesome...😊😊😊

You won me over at "hot probe" ;) Interesting videos anyhow.
