Yes I couldn’t agree more!! To me, the concept of photons being able to interact with such simple chemicals (Cyanotype, Silver Halide, etc.) and literally cause chemical reactions that leave behind images is SO FASCINATING!!! Ever since I learned about how the chemistry behind film photography works about 2-3 years ago, the idea of making my own photographic paper or film has been something I’ve dreamed about doing. Except I never tried to until recently because I had just assumed it wouldn’t work and it couldn’t be so simple, BUT IT IS!!! It’s literally that simple!

Oh definitely not! Try searching for “OV7670 VGA Camera” or some variation of that on eBay/Amazon/AliExpress, you should be able to find it quite quickly. (Also, when I said it cost $2 in the video, that’s what it used to be ~2022, but currently they’re more around $3-$5)

@@KeonsLab I didn't mean the camera module was bullsh*t, I have one similar with integrated esp32. I mean the "turning it around to use as microscope". But I guess it's true. Got to check it 👍🏻

Ohh THAT’s what you meant! But yeah it definitely works! It’s just enlarging the image instead of shrinking it to the size of the original image sensor. Getting a clear, focused image/video though, took about 30-45mins of finely adjusting the threaded lens.

What is the magnification power?

I was actually thinking about that about an hour ago. I’m honestly not too sure so I’m gonna research it a bit… which will inevitably lead to a rabbit hole of some kind, as it always does 😔

@@Voytako thanks! 😄

@@KeonsLab no I thanks for the video

ok haha🙃

@@UnitedElectric Yeah it’s truly an amazing material! I can also agree that within a decade or so the number of places that these will be used in one way or another will increase significantly. (I think maybe high-end EVs could potentially make use of it at some point to shave off an extra bit of mass yet still retain good thermals. Low mass, low density, and extremely thermally conductive. All super unique traits that make it so cool!!!

It’ll be soon! I finally figured out a nice way to connect them in series. Right now I’m almost done the best quality video I’ve ever made and I think you guys are really gonna like it

@@abo3abid1 I’ll very likely do one at some point, I don’t wanna spoil any surprises though. But trust me, the videos I’ve got planned for this year/2025 are gonna be insane! Also thanks for subscribing!!! ☺️☺️

@@eisupremacy9861ooh neat is it like a handheld device or something?

Yeah, and a cheap one too. While not all made in china circuits/modules are bad, they (cheap ones especially) can have misleading product descriptions. For example this inverter can only be used with incandescent bulbs. This is because it’s 120kHz AC output will permanently damage/burn out any 110-240VAC devices designed for 50/60Hz AC (basically everything except incandescent/halogen bulbs)

Steam? I can try but I’d honestly doubt it. :(

@@KeonsLab I would try putting a piece on top of steam kettle and see if steam passes through.

Yeah that’s a good one! I wasn’t sure whether to make one or not but if you guys want one I’ll do it. The attiny13a I remember being super frustrating to get working the first time I tried it. But then I just switched to the attiny45/85 to make it easier.

Omg I wanted one of those dual layer mini DVDs so badly but couldn’t find them anywhere. I did find a mini rewritable mini Blu-ray Disc though that’s 7.5GB per side. It was really expensive though so I didn’t get it:(

Thanks! 😊 I’m glad you found it helpful

Right!!? Based on what I've read about these types of cells (though I haven't tested it out myself...yet...), they're supposed to be able to deliver a pretty acceptable amount of power even in extremely cold or hot conditions. I'm imagining a feature that I think EVs could really use where a supercap bank heats up the car's main battery pack in an extremely cold climate if the car won’t start due to the cold They're also supposed to be much safer compared to traditional Li-ion cells when it comes to fires, since depending on the cell's chemistry and physical construction, it can be possible (in a controlled environment) for a nail to be hammered through one without turning into an incendiary device (GreatScott actually had a video where he did just that, not the incendiary part but the nail through the hybrid supercap part 😅) However I should also note that unlike ordinary electrolytic capacitors or even EDLC supercapacitors , the term 'Lithium ion [hybrid] supercapacitor can be used to refer to a couple different variations of the cells based on electrode composition and placement, which while very similar to ordinary lithium cells, differ slightly in their physical materials, construction, and to a certain extent, their performance. Essentially I'm trying to tell anyone reading this that Lithium cells and batteries are no joke.

If you’re referring to physical pins 5,6, and 7, then they can be used as normal digital pins, either as inputs or outputs. Of course you’d want to disconnect the programming leads before connecting components to them but yeah, they’re totally usable as digital I/O pins! D0 & D1 even have PWM capability!

Thanks!!! 😄

Thanks, I’m trying my best! I’ve been recording for 12-15 hours a day the past two weeks You have no idea how much this means to me. Comments like this are what motivate me to keep going. ☺️

😅 Yeah, I've just never seen one so cleverly integrated like this.

Omg ‘Clip-It’ is the most 2010 sounding name too

As in a USB 3.0 external HDD or a SATA 3 HDD? I'd love to help!

And yes, those COB LED are typically a big array of a lot LEDs in different patterns parallel and in series. They are awesome, but they have some drawbacks as well. "High" voltage needed for example, my relatively compact, round 50W or 66W models, i dont remember exactly, need about 36V for its rated current of i think 1,5A around. About 39V make about 4A (so >150W power draw!). If you dim them, you also have to realise.... either you stick with the regular efficiency but no CRI and color accuracy loss, so you control the light output via PWM dimmer. If you dim them with a "simple" constant current source they will change color and lose most of its CRI value while dimmed. Also, as awesome it is to boost those COB LEDs as my DIY flooder putting out >20.000 Lumen by bulding a array of 2 of them and yank the sh*t out of them by going 4A+, their efficiency goes VERY BAD. The rated current values are somewhat a "sweet spot" to have as "much as possible" light and reliable, yet reasonable efficiency as well. Only going much below this rated current, and only by doing it with constant current will increase efficiency to nearly unexpected levels. My 50 or 66W COB LEDs, when running them on lets say 3W, they are SUPER BRIGHT. Any 3-5W single LED running at 3W will be much darker, so much less efficient. The COB LEDs i use are running on super low current while doing just 3W (36V LEDs, i would guess now around 31-33V @ 0,1A).

Yeah, I put together a kit for a 100W COB LED with parts I got off AliExpress/eBay, and I definitely know what you mean by finding the right balance between brightness and accuracy. The thing is so bright it can light up an entire basement almost as bright as all the pre-existing lights. It consumes ~96W, and if that’s only because my power supply only goes up to 31V and the COB LED is rated for 32 or 36V I think? I honestly don’t remember so please correct me if I’m wrong :) Now I don’t remember whether or not I used constant current in this video, but if I didn’t I definitely should have. I run my 100W COB at 31V (psu maximum) and 3.112A, any more current and I don’t notice any increase in brightness but the Heatsink starts getting really warm. Some day I may get a real powerful power supply that can go up to 40 or something volts and give at least 10A of current 🙃 Electricity is just so cool when you think about it, especially in the context of electrochemistry. The way physical matter like simple rocks & minerals mined from the earth, when put in the right arrangement, can literally generate the very same electricity that runs our world today. Like the way battery materials on their own are only useful for their own properties, but when combined, they suddenly form a little chemical system that is the battery cell. It might sound weird, but whenever I make a battery cell it’s like I’m bringing it to life, so it’s always a bit difficult for me to break it apart to reuse the electrodes.

Yeah it does! 😅

Yeah I’m also trying to figure out what the exact difference between those high power density batteries like the one you mentioned and these supercaps are. I think I’m close to finding an answer, but the stuff gets real complicated real quick so I need to make sure I know for sure.

@@Nayel-Khouatra I don’t but now that you mention it, I think that’d be a great idea! Should I make one?

@@KeonsLab I believe it would be a great idea, as it would allow everyone to share their own experiences, expertise, and projects.

Ok, I’ve made one, now I just need to remember to mention it in my next video!

I definitely agree with you on the overheating. They really do get very hot very fast. I do notice the speed throttling too, but for me at least it doesn’t get as bad as USB 2.0 speeds for any more than a minute or so. ugh, I hate even thinking about having to transfer large files over USB 2.0 lol. I had to copy 32GB once and it took forever

Well, kinda, it depends on the context really. It looks kind of deceiving since it’s about the size of a microSD card, but it’s actually a USB memory chip + controller package. And it’s used to manufacture your everyday USB thumb drives by inserting the chip into a plastic or metal outer shell.

Thanks! 😊 Comments like this are what motivate me and make me want to make more videos!

@@KeonsLab np! keep it up!

What if I told you that these chips are used to manufacture your everyday USB thumb drives? 🤯 Cool right?!! They do it by simply inserting the chip into a plastic or metal enclosure with the proper dimensions for a USB port. hope you found this interesting!

Oh wow thank you so much! 😊😁 Seeing comments like this really makes my whole day so much brighter. It’s also so awesome that you learned something new! I’m curious about what you learned from my video, would you mind naming a couple things? I’m genuinely interested. 😊

@@KeonsLab I've been reading books on lithium ion batteries. Seeing your videos constructing a battery from scratch makes it much easier to study and understand the internals of batteries. It's unlike a traditional graph that's boring and tries to explain how things go together with a simple picture and scientific words, you've actually shown how to make a real battery and it worked! Thanks for sharing with us your information. I appreciate the time and efforts you've kept in putting this together for us to see it.

@@mansoora.7322 This is truly the most heartwarming compliment I've ever received and I'm so glad my video helped you in a way that traditional means couldn't, since that's always been my goal when making videos.

The whole thing was $9 free shipping, maybe 10 with tax. I’m using it with my SSD and it works great. Transfer speeds via USB-C on a Mac are SUPER fast. Like gigabytes in seconds, but for some reason on my Windows computer it doesn’t go any higher than 50-80MB/s, even on a USB-C port

The orange adapter? Because I designed and 3D printed that, but I could make the STL files available if you have a 3D printer. I’ve also been thinking of maybe making a lot of them and listing them on eBay or something at a really low price since it’s just a tiny piece of plastic. Although the USB 3.0 version of the UDP chips fit in standard USB ports no problem…

@@KeonsLab he's prob talking about the Usb A to Usb C adapter that you specifically said was on aliexpress, not the plastic case you 3d printed.

Yeah it’s like magic, and speaking of Nikola Teslas Inventions, fun fact is back in the 1890’s when most people didn’t know about radio waves existing in general, he was demonstrating a very basic little RC boat he had made and the people watching the demonstration were utterly amazed at the concept I bet to them it was like he had magical witch powers or was a god or something 😂 And they wouldn’t at all be considered dumb for not knowing because it was literally a branch of science and physics yet to be properly explored.

@@faizannekaha You mean like with a hard drive that consumes 1 Amp? Unfortunately I don’t think that’d work unless you have an external 12V power source. The reason it only works with 2.5” SSDs and HDDs is because they’re made to go into portable devices, so they require much less power to run. For example my 1TB 2.5” HDD only needs 5V and 0.55A to operate, which is well below the 0.9A max. current that a USB 3.0 port can provide. I hope this makes sense 😊

If the port can output 1 amp but usually it only gives 0.5 amps

@@KeonsLab okay 👍

@@Dan_The_Paper ok

@@Atri-c2e on AliExpress, I think I left a link somewhere (probably on the main video). If you can’t find it let me know and I’ll update it :)

True, especially with an actual HDD that could be a concern, but at least for my own personal use with SSDs, since I don’t move my drives around a lot I don’t anticipate any issue.
