- Here I build an electrospinner using homemade equipment!
Thanks so much for watching! Let me know if you guys have any feedback in the comments! It really helps and it's how I learn to get better. Next video, I plan to mechanically test the valve in some kind of flow cell! So stay tuned!
SAFTY NOTE:
Do. Not. Try. This. At. Home.
Electrospinning is very dangerous, without the proper training and experience it is possible to get hurt. Electrospinning produces fine fibers that can be inhaled without proper protection. I took as many safty precautions as possible: used medical grade PCL, room air filter, and N95. In theory, PCL is perfectly safe to inhale, but there are obviously risks to inhaling anything that's not air.

WAIT! You never tested the valve Riley! I know lol
For the next video, I plan to do some hemodynamic testing of the heart valve! So stay tuned!'
Final thoughts:
Thanks so much for watching! Hopefully you enjoyed the video and footage, feel free to leave some feedback. Be honest! It’s how I improve and I watch each video to be better than the last!
Let me know if there are any mistakes and I’ll make a note to correct them!
For the next video, my plan is to continue working on the heart valve. Now that I have a heart valve that looks like one, it’s time to see if it works like one!
This is awesome. I'll definitely be following along, and also attempting to replicate some of your work. I have my own ideas along these lines that I'd like to try out (which is how I came across your channel), but you're clearly way further along your journey than I am, and I'm glad for the ideas and inspiration.
The last piece of music really hit. it was perfect for the mood, and its addition at seemingly the end of the video, as if you had suddenly decided to keep going after filming really helps carry your dedication across. We practically felt your investment!
Last piece of music was a fine bookend, but most of the previous bits were far too loud / distracting. I'd target it either being at your voice level or slightly below, but right now the music is louder then the spoken sections. At least IMO- I'm not a content creator type.
Also, congrats on the success! I was kind of wondering if there might be some other approach- maybe not coating the positive mold with the conductive paint, and only the pillars, or say only have the rod at ground potential. Not sure what the effect would be- I would think the fibers might not adhere as strongly to the print, but there could be other effects (charge buildup, other)
How u only have 1000 subs. Amazing content.
fuking great!
Really nice video and project! As other commenters said, this feels like RUclips in the golden era. You really captured the spirit of sharing something interesting and novel in a humble and genuine way. Thanks for putting this together.
There will always be a place on RUclips for authentic exploration of an interesting idea.
Whoa, it's the goat
Wow thank you so much! Really appreciate your comment, crazy to see you here!
@@WrylyRiley I just hope that having both @AppliedScience and @NightHawkinLight comment helps your channel grow somehow. They are definitely two of the experimental goats on the Tube.
This is awesome. Just demonstrating an easy way to make a flat fiber mat on a piece of foil is super useful, and the other methods become all the more useful from there. Great job! Got an easy sub from me.
Thanks so much!
This is crazy to me, I grew up watching your videos and trying to recreate them in my kitchen lol. Super thankful for those memories. Thank you for being an inspiration!
I'm just a guy eating jelly beans in my pajamas. Super cool to know you watched my videos and they somehow contributed to you doing something as awesome as this.
It's nice seeing you in the comment section here!
I likewise am a big fan of your content! 👍
Yup, same
I design parts for injection molding, and the whole time was chanting, "Draft! Draft! Draft!" in my head. Adding some draft to your molds should help with removing the final spun part. You're already using grease as a mold release, which is great. Are you sanding your molds? The layer lines on the 3D print are probably making little grooves that the fiber mat can lock into. If you can sand or vapor smooth, that should help. Or reorient your print so that the layer lines are parallel to the direction you're going to pull the mat off the mold. Awesome work man! I want to play with this process
This is great input! Thanks so much for the comment! I started to sand the molds later in the video, but only after I started using grease. I'll definitely start using drafts for the next molds - it's a bit tricky removing the nanofibers from the current molds.
@@WrylyRiley this is such a cool project! I really think you might want to try vapor smoothing instead of sanding, too. If you use ASA filament you can get a glassy surface with acetone vapor smoothing. I also think you might want a slightly heavier draft than I would use for injection molding. Like for the ABS parts I design, I use anywhere from 0.5 to 1.5 degrees of draft, and that's enough to free the parts, but ABS is quite rigid. I suspect you might want something more like 5 degrees or more for such a flexible structure, but that's just a guess. Good luck! I can't wait to see how this goes
@@WrylyRiley I have made moulds for composites, I agree about the layer lines causing a mechanical lock, but I wouldn't bother sanding the 3d print, the materials don't actually "sand" that well. I would coat it with a high build primer then sand the primer, then use your mould release of choice.
To add to this, could you design the "mold" with a shell rather than just a solid piece, and use a solid piece to hold the shell pieces in place while spinning the fibers?
Once you're done spinning, remove the solid piece the the shell should just be able to fall out.
You can smooth out print surfaces using UV cured 3D printing resin, it should be easier to sand/polish. On the outmost edge of the "stand" part of your mold you could run a bead of a thin thread of cotton or your polymer to help you de-shed your valve. May also be helpful as anchor points for testing down the line. As with any aerosolizable nanoparticle, you probably need to consider your PPE; that stuff can be nasty. Phew, finally... It might be worth thinking about having your axis of rotation in alignment with your needle with your mold at the end of your shaft facing the needle; it may provide alternative geometry options beyond draping. Great work and project, am subbing ^_^
I did a double take when I saw the view count and it was *2.4K* instead of 2.4M. Even more unbelievable that the previous video didn't even break 1000 with the sheer quality of both.
Oh we're going big with this one
Yep. Talk bs about "science" = 7 million views. _Do_ breakthrough science to save lives: 2.5k.
I always love it when I find youtubers right before they make it big.
Amen for true RUclips videos coming back
Thank you! Just tried to make something I would watch :)
I got a St. Jude valve installed at 25 years old. For the past 15 years the constant clicking has been driving me NUTS! I can hear every time my heart skips beats which leads to bad anxiety at best or panic attacks as worst. If getting this kind of valve installed was an option I'd go through that surgery again primarily just to be free from the click and not having to take rat poison to thin my blood plus PT INR checks every couple of weeks anymore being a far second
I hope the video after iterating mold geometry comes one testing it's endurance as a check valve with a blood analogue and regurgitation around the ribs/pillar supports. Could be a fun project to collaborate with mechE and echocardiography majors for designing tests and imaging regurgitation and turbulence
Fudge, the first paragraph is reminiscent of something Edgar Allan Poe could have written. Hope you are doing fine
if you ever need another replacement look into TAVR tissue valves or surgical tissue valves (the tissue valves are bioprosthetic and have no clicking), the technology has come a long way from 25 years ago and they pretty much last as long as mechanical valves with no blood thinners!
Neat! Felt like I was watching a 2010 RUclips video! No overly fancy editing but maximum knowledge/second. I work in a cardiovascular research lab myself and we often test out various valves for hydrodynamic using a device called the Vivitro Left Heart Pulse Duplicator and structural performance using a Bose Tensile Tester. The duplicator mimics the left side of the heart and has flow and pressure probes attached to it. While it is a lot of work you could make your own valve tester, see "Open-source controller for dynamic cardiovascular models" and "Redesign and Performance Evaluation of
a Cardiac Pulse Duplicator
" to test your valves. You could also design a relatively easier mechanical tensile tester to see the material's stress/strain properties, see "Standardized tensile testing of soft tissue using a 3D printed clamping system" and "FreeLoader: An Open Source Universal Testing Machine for High-Throughput Experimentation".
Thanks so much! Thank you for the help too! My plan for the next video is to build my own hydrodynamic testing device - I never thought about looking at opensource projects! This is super helpful!
Watching the march of progress as you made each iteration was really nice, I think your editing and pacing was spot on
Thanks so much!
My god this video is a perfect example of what makes RUclips amazing.
Thank you so much!
It kind of blows me away how much Master's and PhD-level work is going on in people's bedrooms for upload to RUclips. Very cool. Are you going to hook it up to a tube and show it actuating pneumatically? That would rock!
Thank you! Yes! For the next video, I plan to create a flow tester that pluses fluid to actuate the valve flaps. Just felt like the video was way too long to include it here lol
Shout-out to the one person who was actually looking for this video instead of THE ALGORITHM just leading them here. Really cool project! Glad you were able to get it to work.
Dude, I'm a picky viewer and really found no fault in the format. I clicked because I had no idea what elctrospinning was and you 100% delivered on what it is, how it works, and a way to DIY on my own (no personal interest, but it Could be the exact thing someone needs). With that hook set, I stayed to see your trials, the detailed video was awesome... you basically nailed everything I look for. Something technical, something creative, a good pace (well, I watch Nearly everything at 2x speed, but some are slow even with that). I didn't feel like there was a lot of fluff/filler to make the video longer... in short, you couldn't have made a more ideal video for me.
Now, since is the first I've seen of your videos, I'm off to look at the rest.
Wow thanks so much! Really appreciate the feedback! My goal with each video is - for each video to be better than the last. SO don't have high expectations for my previous videos lol
Absolute Westworld vibes. Printing heart valves today, entire bodies tomorrow.
That's the plan! Gonna do a Tendon at some point too!
I work in the medical device industry, and this is cool as hell.
Pretty sure adhesion to the 3D print is the issue, the surface is way rougher than the scale of the nanofibers, so they have a lot of nooks and crannies to grab onto.
I'd suggest either a highly-polished metallic target, or possibly having a thin silicone barrier just over the surface of the collector. It shouldn't affect the attraction properties of the target, just provide a much smoother surface.
Subscribed for the ingenuity.
Another thought: if you could create a target that was inflatable, like out of conductive silicone, it could be pressurized during the forming, then deflated to make removal easier.
Also, you might want to check the biocompatibility of the polymer. That's out of my expertise, but I know it's very important.
As for the video aspect, not too much i can say to improve. Very authentic, good editing, enjoyed every minute and only wish to see more soon. ❤
Thanks so much!
Nice work man, i'm looking forward for the next one.
Thanks so much! Glad you liked it!
180 views ??? Man you deserve at least 200k for the research. Nowadays science on RUclips is like modernday renaissance. With modern tech on man can build society from bottom up and also destroy it and nobady can do nothing abut that. Knowledge is so free that its funny that not everybody uses it. So many knowledgeable people nowadays and so many stupid idiots. Such a discrepancy its baffling.
Awesome videos, i think you shoul try to grow some cell in this structures.
Thank you! And for sure! That is one of the future plans for a video! It might be a while before I build up the facility to do so, so stay tuned!
Maybe in the future you can grow on this tissue cells with the DNA of the person it's going to be transplanted in, helping the body accept it better. Might not be needed, but since you brought it up, this might be an obvious usecase.
Most handsome and intelligent RUclipsr north of the Mississippi.
Lmao
Amazing man! I would try adding a small percentage crushed coals, ash or other fine powders. Aswell as mixing types of polymers in different ratios. If you've seen the Thought Emporium, he tries to make different types of spider silk, and the key is variations of polymer ratios with different properties. Certain proportions will give you stronger and more flexible materials. Amazing work! Good luck and all the best! ❤
Thank you!! And thank you for your support over the last few videos!!
I am planning to experiment with different materials at some point, once I better/safer set up!
Make a water filter in the next video! Why not?! You already have all the tools for it. There are so many things you can do with this technology! This needs to be talked about. I look forward to your next videos. Good job!
Thanks so much! Glad you liked the video and learn a lot!! Honestly, a water filter would be super useful for my future plans, so I might have to try it
The algorithm works in mysterious ways... I have no idea how I got here but it was fantastic.
What an amazing video!!!
Thank you!
Работа действительно стоящая и важная. Спасибо за то, что вы делаете.
I know I am supposed to be focusing on the science, but he's just so dreamy
This video was great! I learned something new. This makes me want to produce large sheets of fabric with tens of nozzles and a large spinning drum! I wonder if this method can be used to produce supercapacitors with introduction of the graphene into the mixture.
Bro thinks he can get spiders to do his work and show us a video saying that he 'did it' and we'll believe it.
Of course we'll believe it I mean look at what this gentleman has created here. It's beautiful and amazing and brilliant. Imagine the applications of such technology this will (if it already hasn't) create a revolution in the Medical Electronics and Transplant technology fields.
I don't really know what else to say, I feel like my projects looks like a paper mache volcano in contrast to THIS. 🤩
And I ain't even sad, because this is far superior.
Hahaha thank you so much! Really appreciate your words!
I suppose I didn't love the repeated music but really this is a spectacular video. I'm very curious now to see how well those valves would function, definitely going to be there for the follow-up.
Thank you so much and thank you for the feedback! Stay tuned for the next one :)
As someone with a Unicuspid Aortic Valve, this is a pretty cool video
I'm flabbergasted about all this. So much specific knowledge and a lot of persistence is needed to succeed like this. Amazing job. I hope you keep sharing your work, its invaluable.
The diagrams were great, and I love that you’re not shy to show imperfections and errors! Such a refreshing thing to see when everything is hyper polished.
Though, lots of polish came through even in that! The filming, lighting, editing choices were great 🌸 keep it up and good luck with upcoming projects!
Thank you so much!
Seemed like the thickness of the three supporting posts were preventing the flaps from closing and forming the seal. It stands to reason that making them as thin as possible would be ideal for forming a proper seal, or even designing it so that they could be removed altogether in such a way that the fabric would retain its shape would be a huge improvement to the function of the geometry.
I completely agree! I tried to make them as small as possible, but ran into printability issues, so the pillars stayed pretty big. I'll definitely look into other solutions for the next video!
@@WrylyRiley Maybe a mounting point for a small sewing needle or pin would be a simple and elegant solution. They'd be conductive, cuts down on printing time, and you could remove the pins after the valve is spun.
Dude, can I say that this is hands down the coolest thing I've ever seen. As a small time maker I'm blown away, this is simply amazing.
The fibers will take a form called minimal surface. It is a partial differential boundary problem. Here you have to find the inverse problem to find the correct boundary for the desired shape (off course you can approximate it by trial and error), and moving the receiver end can make it do interesting things. Cool!
Wow you put into words what I was trying to do lol. At first it was trial and error, then more thought went into the design and I got the final design!
you can try this way to make a great surface smooth: after you have sanded the entire surface, apply the primer and the electroconductive paint, do electroplating with copper sulphate, sand with 400 grit upwards and do polish. in this way you will have an excellent metal surface and prevents adhesion, above all it does not leave traces of paint
Amazing video! I am currently doing my Bachelor's thesis on wet electrospinning, and I have also modelled and 3D printed a mould that has a unique volumetric shape. Loved your content!
Thank you!
That is so cool, I'd love to know more! What is the application and material choice?
Amazing video, both in content and pacing. It's super creative conceptually and the videography and editing match that. You got the sauce brother, subbed and enjoy getting tossed around in the algorithm with this one. Good luck with your future projects!
Excellent work Riley. A couple of suggestions if you are open to them.
Spray mould release will probably be a little easier than the grease, but using compressed air (at a fairly low pressure) should help to remove the electrospun fibres (think de-gloving).
Electrospinning in a temperature controlled, vented chamber will give much more consistant results due to variable differential evaporation rate of the solvent(s).
The setup looks to be quite close, this may end up with blobs forming on your matts, it may be worth experiementing with drawing the distance out to ~ 60-70cm, but you may need to up the voltage, if you can't then don't worry too much about it.
If you want to strengthen a particular section of the matt, there's a trick where you half run your matt, then pause, wrap the part you don't want to thicken with plumbers PTFE tape (so much of that got nicked in my PhD) then continue running. There will be matt formed on the PTFE tape, but it's easy to remove and doesn't stick to the underlying matt.
This is impressive work into a youtube video. keep up the good work!
Thank you so much for the feedback! Any, and all advice is happily welcomed - it's how I get better!
Spray mould release is a good idea, will order some now! It did occur to me to use compressed air, but the order didn't come in time for the video lol.
Great input on the electrospinning techniques! That's a pretty cool idea with the PTFE tape, I'll try it out!
@@WrylyRiley 💛. looking forward to seeing the next installment.
Of course the project itself was well done, but your mindset is really admirable. If I were to attempt the same thing and hit a roadblock, I'd think failure. But every time in stead of saying this result was a failure you said it was progress. inspirational.
I really couldn't give a toss about the valves, but the tech is interesting and it was a good video. This was new to me. Cheers
Digging the 2010s vibe of the video. This is golden! Reminds me of Cody's Lab.
in addition to the draft and vapor smoothing the negmolds comments :
- try conductive grease
- try a few channels in the mold so you can blow air inside the mat to unstick
A vulcanization post-process may help improve the elasticity and durability. This would form cross links and more closely mimic the elastin-collagen matrix in a natural valve. This was awesome btw
Thank you! Good idea, I haven’t thought about crosslinkng the PCL yet!
When you said "SO CLOSE" I chuckled and was like, you are like 5% haha
This was way better than Wintergaten though, at least you achieved!
The music at the end was well suited.
This video makes you think how incredible the design of the human body is.
Our organic complexity is made of atoms that are billions of years old, created in supernova explosions.
I’m wondering if this material would make great lattice for tendons, ligaments and muscle to grow on.
Heck even nerve connections!!
🇦🇺🤜🏼🤛🏼😎🍀☮️☮️☮️
Thank you! It's crazy to think about where the atoms come from and how they make YOU! I have a future video planned on making tendons, so stay tuned!
This video is of great production quality ! I'm a plastics technician and a builder and was amazed to discover not only a new technique but someone applying it to a DIY build. Subbed and shared ! Great content !
This video is why I still have hope for RUclips as a platform. Absolute amazing stuff. Thanks 🙏🏻
I worked in an artificial heart lab in college and started working with this exact process to make mitral valves. I graduated before it went anywhere, but it’s a cool coincidence
it's basically the same as powder coating process
This videos' montage music, produces within me, a visceral humor response.
It's so good.
This is one of the coolest things genuinely unique things I've seen in a while bro keep it up!
Fantastic video, dude. Can't believe you have 2k subscribers! Feels like I'm in at the beginning of one of the next million subscriber tech channels. Excited to see the next
Thanks so much!
Amazingly entertaining video! You explain clearly the theory behind what you are doing, and the video is well paced.
Thank you!
A couple of ideas for easier removal of the final product: make the whole mold conical, meaning instead of straight walls make it flared so that when the spun fabric comes off it's being pulled towards a part of the mold that's smaller than itself. Also sanding and polishing, which no one likes to do. But if you have a vibratory polisher you could make the mold longer than needed, toss it in the polisher and then cut it to length.
Another idea that you might be able to get some content out of would be to electroplate the plastic to get a smooth metal surface instead of a painted one.
As far as the pacing of the video, music, etc...? It's over now and I did not even notice the time passing.
Absolutely loved this video! This is amazing tech presented in way, that is very easy to understand, and entertaining. I'm shocked that this has so few views.
One thing I think you could pretty easily improve on is your sound editing. At least at 7:19 the music seamed a bit loud.
Keep up the good work, and I hope you get blessed by the algorithm!
This is great work!
Good to see SBF landed on his feet
I love your Ludwig merch lol but seriously awesome vid! Even just the option creates amazing potential. Also dope music and well filmed. Appreciate the concise description.
Thank you! Glad someone noticed mogul moves!
I watched you hit 1k! congrats! you are so cool and can't wait to see what you do! :)
This was illustrated with the grease: you don't need the actual *surface* to be conductive itself. The important factor is the electrostatic potential between your syringe and your target - if that target happens to be surrounded by something that isn't conductive itself, all you've essentially done is add an insulator with a higher dielectric constant than the air insulator (Dk=1) you had to overcome in the first place.
Felt great embarking with you on this scientific discovery journey, keep up this great work and good vibe
Thanks so much!
Genuinely amazed! Can’t wait to see you test it out 🤩
Seeing a lot of big names comment on your video makes me think your channel is gonna blow up. Well deserved with such awesome an educational content.
The wait for these videos are always worth it!
I wish I had the ability and patience to do 1/64th of what you do.
I wanna get into mechanical engineering specifically steam & diesel engines but damn it's hard finding a place to start or where I can find consistent knowledge.
This was great, had me hooked through the whole thing. Looking forward to future updates/testing/projects.
Put it in an acrylic tube and see if it works!! Great work!
That’s the next video! :)
Awesome video! I was shocked this is from a
Absolutely love the video, thank you for the length of the video. This was about the perfect length and a really amazing amount of detail. If I saw an upload like this from you once, maybe twice a month I would come back every time. I really enjoy this kind of content where people are using everyday technology to innovate on top of already existing techniques for our own better understanding of how they work. I think being human we gotta continue to expand the scope of things we learn because we're always discovering new things. A child growing up 100 years ago would not have the amount of things to learn as a modern day child. The music you used was also fantastic, the classic music is not just a beat to sing to but actual attention to how it is made and played as to evoke emotion and take you for a ride without saying anything and that coupled with the footage of you spinning the fibers and working really help to keep a viewers attention in my opinion. I think the only thing I would have liked to see is the modeling process however simple it may seem to you (I can kind of imagine what you did to get the shapes you did but other people might want to know). Potentially go into some more detail how the setup itself but honestly all things considered this is a lovely 8/10 in my book. Please keep making content :)
That’s AWESOME 😀 Great content!!
Thank you!
This video gives me major AppliedScience/ThoughtEmporium/BreakingTaps vibes, and I love it! Subbed, looking forward to more!
Thank you so much!
Thoroughly enjoyed the video, I'm glad it came up on my recommended page I have someone with an artificial aortic valve I find it quite amazing that you're able to just do something like that at home and it could possibly be something we use in the future even if it's simply used as a framework to grow tissue into.
Thank you so much!
Stellar work, mate!
Absolutely incredible.
Super interesting video and I love you whole workshop setup.
what an incredible video and project, great job!
Thanks for sharing this really cool concept with us. I really enjoyed the video a lot ❤
Thanks so much!
awesome to see another update on your R&D with electro spinning, and the reason it put you down the rabbit hole to begin with (if i missed it previously). This is great stuff, keep pushing to get stuff done and learn what your missing. Your doing awesome!
Been a while since i was convinced to subscribe based on 1 video. This one did it.
As to feedback, the music transitions had me turning the volume down a bit as it was so much louder than the voiced parts other than that you have a unique and interesting style. Loved the black paper explanations and will be looking forward to seeing what you make in the future!
Thanks so much and thank you for the feedback! Yeah, I messed up the volumes a bit in this video - will be fixed in the next one!
Amazing work!
Very cool video, thanks for putting so much time into the project
instead of conductive paint you could coat the model with electrolysis which puts a nanocoating of metal. It should make a more uniform coating of the threads. You might even be able to manufacture an aerogel structure that is soluble so you can dissolve the structure leaving the threads and metal. Not sure if you can use titanium for electrolysis but if you can, and you use Poly-2-hydroxyethyl methacrylate then you should be able to create a part usable in the body. To be a working and safe part you'd probably have to refine your spinning method to make it uniformly coated for maximum strength, and it may or may not help to created a fused/melted edge.
anyway good video,
Good idea! I’ll definitely try electroplating, should make the surface smooth too, which might mean the no grease!
Stellar video, amazing to think the base technology is so (relatively) accessible.
16:30 bro literally designed the pizza thingy
Hahahahaha I just realized what you meant!
The over-engineered pizza lid holder thing
Yeah couldn' figure it out for the life of mehow its called. Great video btw!@@WrylyRiley
This video is wildly good! Great drawings, explanations, test setups. If you continue putting this much effort in videos your channel will blow up. Plus a lot of people will want to pay you large sums of money to work for them.
bro i subed just from your attitude in your intro. heck yeah. i know your gonna blow after a glance at your profile. youve got the topic now you just need the content. structure your vids like this but dont go too overboard. love the start. lookin good
try something like a cooking spray that wont distrub the fibers while being able to evaporate off the fibers even if it takes a little longer. maybe cooking spray itself? lol
just thought, vasoline might work?!
Vapor smoothing is definitely a good idea for surface quality. Great video, a lot of over used music. I’d rather listen to something I don’t like than something I’ve heard before. Subscribing and excited!
Thank you for the feedback it’s super helpful for me! I stared at this video for hours on end and started to miss simple things like this!
undiscovered gold channel
Great inventiveness !
You can also try water-soluble print materials.
Good idea!
Most interesting video in a long time. Will definitely try this for other contexts. Thanks for the inspiration! Subbed ❤
Ok, well this is going to be an awesome channel.
Some thoughts of varying values:
Your hair looks super nice when you comb it up. :)
The rate of spin of the outer most circumfrence seems to directly impact how much of the total elasticity is used when the fibers are forming, faster spin --> More elasticity used
Consider printing with small holes and channel internal to the model so you can use compressed air to free the material from the mold.
You may need to regionalize the magnetic fields with smaller embedded wires, and then actuate them over time to help you control thickness in given areas. A small mircocontoller and bunch of somewhat fiddly leads (though I bet you could engineer a standardized radial socket fairly easily) could allow you to coat different parts, different amounts, time this with your rotation rate, either with math, or just cheat and use an acceleromter/gyroscope and you could lay down fairly intricate layers
The music is great, the pacing is slow which is expected for a project like this where both you and the audience is learning. The diagrams which I can only assume were hand drawn are incredible, please keep this up they are highly detailed, visually pleasing, and deliver information in a new and refreshing way. I truly hope you can get this channel going because I will be awaiting your next upload.
Seems like this video got picked up by the algorithm. Very cool Video an topics, i hope your channel go viral and you continue on such interesting topics. Best of Luck!
Thank you so much!
Excellent work
This was an awesome video! Watching you work through the process, come up with ways to deal with the challenges, and finish with a worthy proof of concept prototype, was absolutely fascinating.
It will be really interesting to see where you go with this.
Cheers, from another new subscriber!
This is super impressive work. Brilliantly presented too.
This is incredible and inspiring
Subb'd, great work all around and entertaining, more people need to see you!
