"I suppose I'm afflicted by a unique kind of laziness where you end up doing more work" that's called engineering
The hell. I've been an engineer this entire time, but I'm getting paid like a teacher.
@@endlesswanderer1753 university teacher?
nah that's adhd
Quantum laziness.
Slothfulness is not doing anything, laziness is finding more effective/efficient ways to do stuff. Be lazy
"I'm eyeballing it, but I'm eyeballing it carefully"
Love this definition of engineering
Laser eyeball
And eyeballing it to the raw surface of the stock rather than the cut surface...
8:47 This is going to be my new work credo. Eyeballing stuff _"carefully"_ 🧐
OMG,I started laughing so hard . I woke up my wife at like 3am. Eyeballing it carefully,what I laugh.
in the industry we call this using your ‘eyecrometer’
One thing i noticed is that if your friend has any sunscreen on their fingers when they touch the amulet, the sunscreen can potentially coat the sensor and offset the measurement.
underrated/10
You didnt notice that, you thought of that
@Professor Ed why thank you for that studious and essential correction
@@ettat.3806 And thank you for your needed insight, very thoughtful and helpful 🖤
I forgot who this was, then i remembered, oh it has been a journey. So glad to see you back. Love your projects.
Same
I saw the video title in my subscriptions and thought “Am I following someone who'd believe in an amulet protecting against UV?” Great video.
Hehehe happened just the same although the name was so familiar. Great @mitxela, you are admirable 👍🏻 I am a fan hehe
exactly
Damn, I think this exact thing every time I come across one of his videos. Perhaps he should change his name to something more memorable?
24:45 Do you even know how the full saying goes? "A Jack-of-all-trades is a master of none, but oftentimes better than a master of one."
As this project so perfectly and elegantly demonstrates.
"The" "full saying"
@@hikingpete are we just quoting random words?
@@GirishManjunathMusic No, Stefan is pointing out that there are a few sayings that purport to be a completion of the common short version, and it's under question whether the short version is incomplete in the first place.
@@Encysted ah.
Yea but a trade full of jacks. Would you master the jacks or the trading of the jacks? And what kind of jacks are we talking about? And aside from the toy, how would one master a jack? Adding a master of trade is only a master until someone says “no”….
He's back and there's an hour of content!?!
Am I in heaven?
Had the same thought!
Only noticed that nearly an hour had passed when the video ended. Guess that speaks for the quality of his video.
"if you drink this bottle, you won't even get sick -- you'll straight up DIE" - That was just perfect. The extremely dry way he said it made me laugh out loud.
How to improve it:
1.) Use individual sensing diodes for various UV wavelengths and measure the values yourself with ADCs.
2.) Use an electronic paper display, it fits perfectly with this project.
3.) Make it solar rechargeable with a little super-capacitor.
4.) Add a quartz glass window.
are there epaper displays with the dimensions of a CR2032 battery?
@@MrPhilip796
Is it really necessary to make it the dimensions of a certain battery ? Like, what if it’s solar rechargeable with a supercapacitor for energy storage ?
@@cezarcatalin1406 I feel like it'd end up looking weird if you didn't fill out the round window of the amulet, and I mean I don't wear jewelry, but if I was to I don't think I'd wear something that looks weird as that just seems to defeat the point?
@@MrPhilip796
Ok, that’s actually a good point... maybe we can have a round epaper ? Or... maybe we can have a square amulet... OR maybe we can have an amulet like a star with 8 corners made of two squares placed at 45 degrees and that allows both a square screen and other sensors/things in the other four corners.
great idea, but I agree with the fact that this would look weird with a square/rectangular display.
Also, the small size is what makes it unique.
ah its fun when the documentation looks good at a first look, so you develop for it, and then realise it makes no sense
reminds me of a certain home server program whose example plugin the software refuses to load, and the documentation is full of "this function takes two float inputs and outputs a char. but what does it actually do? secret ;)"
Ah yes, the old "setValue - this function sets the value" type descriptions...
Honestly the amount of times the published example for even popular libraries flat out doesn't work is ridiculous.
Made this mistake in a systems lab class, datasheet provided information suggesting the sensor we were using was first of first order response and our best fit was a crazy second order with free integrator.
Never trust the datasheet unless you have already checked the product yourself.
To say you're an inspiration is an understatement. More long-form videos please!
I've never even seen a lathe in person, but machining seems so extremely satisfying. Being able to make high quality good looking metal parts that combine form and function must make you proud.
It's really awesome getting the parts finished. There are days you spend eight hours standing at a lathe though. Also if you decide to learn metalworking because lathes chew people up if they get caught.
@@carloshernandez2561 I have seen a fair share of industrial machinery, but lathes remain the most worthy of the sign "this machine does not know the difference between metal and flesh, nor does it care."
a lathe will not only kill you, it will hurt during the entire process.
@@ledocteur7701 man that russian lathe acciden lives in my head.
Great project! Thanks for the research with that sensor.. I got some of those here and would have expected that they actually work. I'm asking myself if the extended UV-A its measuring could be taken to extrapolate and estimate an UV-B reading.
Did you consider giving the little handle longer shaft and cutting a thread? I can imaging simple M2 thread cutters would work here, or am I just overestimating the size of that?
Another way could be to drill trough and solder from inside letting it flow to the outside.
Hi! I think it's still a good sensor, if we only care about direct sunlight, I just wish the documentation was better and that the calibration numbers were correct.
The "proper" way to solder the join would be to use a high-temperature solder with borax flux, which doesn't go runny when it's heated. Then you can just place a small amount of solder on the join before starting, and it'll wick into place under the blowtorch. That way shouldn't even need a hole or divot in the brass, the hard solder on its own would be strong enough.
@@mitxela if it wasn't a present I'd probably use hot glue 😂
sadly the bad documentation is something a lot of these integrated (I2C/SPI) sensors have in common. I recently worked with a Bosch BME680 air quality sensor and I could not get the humidity reading to work properly. Maybe the batch I got (tested 5 units) was bad, or I have overseen something, but I could not get that register to work, even if the config registers are set the same way as the datasheet tells me to do...
Same with a lot of these sensors. Sometimes they just don't work correctly.
Always appreciate the monumental amount of effort you must put into making these vids. 👍
"It needs one more thing"... honestly thought it would get an inscription of sorts, or maybe just a nice way of presenting it as a gift, but a MANUAL?! Geniously funny, and nicely done too.
I made a conceptually similar amulet several years ago, but no where near as elegant or attractive.
I also recently made a UV detector for similar reasons, but I didn't think to make it look nice. This is why I'm subscribed to you, and not the reverse.
I saw "UV Protection Amulet" and came over here all ready to be outraged by some more pseudoscientific bullcrap about the "energy of the universe" or something. Turns out it's actually a nice sensible sensor that should be a genuine product on the market. Honestly, you should market this.
This an amazing little project! Art, science, machining and code, you've got it all!
Welcome back Mitxela, so glad to see you once again ;)
This is one if my favourite projects on youtube. Blending art and circuits is what I am all about! Thank you for sharing
What a wonderful entertaining project! Your work kept me mesmerised for the entire duration. I hope your friend enjoys her amulet as much as I enjoyed watching you make it.
I am very amazed by your skills and creativity!
This project combines so many disciplines and you pretty much master them all...
electronics design, PC Layout, science (well, at least a bit), software (I would have written the whole thing in C, but assembler is always cool!), metal work etc.
I am glad that I am subscribed to your channel, it really is a gem on TH-cam. Please don't change your format, I won't care if it takes months for a single video if it amazes me as much as this one.
Its amazing watching the whole thing through, with in the final assembly and ad the CR2032 goes in you realise how massive the battery looks, and the whole sense of scale is finally put into perspective. This is some incredible craftsmanship.
Whenever I watch a mitxela video I go through a sequence of emotions. Fascination, lamenting that they're not more popular and finally acceptance that such sophisticated beauty is probably beyond the grasp of most people. I hope he appreciates that he brings so much joy to the few who don't find much of it in more popular content.
please tell me youre making more videos like this... this brought me a joy and peace that other channels simply do not have
And here i thought TH-cam is again going braindead and suggesting new-age WooWoo like wireless ESD-armbands, but this was a nice idea and project.
Holy crap, I watched through the entire thing...
It was so well edited with so many great and satisfying shots that i didn't even see the time pass!
You have another fan. I was hooked by your volumetric display, but this is beautiful too. My destiny finds me back in England, and now your metalworking lessons are another reason to go. Thank you for the inspiration and ingenuity.
I really enjoy these long form project videos
give me lots of ideas of things I want to try
What a cool and useful amulet! Loved this project
I'm glad to see yet another amazing project - super well executed!
This is a great video. Nice mix of a bunch of different disiplines.
This was really great, I like your storytelling. It's fantastic how you show every little detail to your project. I'm more like the software guy but you did a little motivation in trying out getting hands on hardware :D
I have a high appreciation for your aversion to copy-paste code and wanting to source proper information.
"i'd like to think that there are a few
jewelers watching and cringing so hard that their teeth melt"
Me, a watchmaker: writhing in pain
Very enjoyable video! Most impressed that you wrote a manual!
Yooooo mitxela! Wow, I can't believe it's been 7 months, so happy to see another upload!
The amount of effort you put into this is sbsolutely astonishing- fantastic work!
Wonderful and whimsical and as enjoyable as always. Lovely piece.
As someone who has no substantial knowledge of the kind of work being done in the video, I’m impressed with how interesting and engaging I found it! My attention span for most TH-cam videos tends to be around 5 to 10 minutes, but I was never bored while watching this. I also found the narration both funny and informative! Really glad I discovered this channel, keep up the great work ^^
I have no idea on how or why I came upon this channel in the past.
But gosh darn am I glad past me found it !
Thank you for your content !
Very cool - thanks for that in-depth video with all the great explanations.
Amazing work as always. Your friend must be so lucky to get this gift!
don't worry about how long it takes per video, these are absolutely brilliant!
I really enjoyed this project.
This is the weirdest ASMR I've ever watched. But it works.
Happy to see the manual isn’t overlooked. It’s the icing on the cake for me.
I remember having issues with Vishay parts. And I also learned very much to always check the data sheets and read up on parts before I purchase any components, especially if something is marked as obsolete.
Awesome project. Love your eye for design and aesthetics. I'm a recent mech eng grad that mostly does electronics, good to get into product design as a career one day!
This looked like an insane amount of work and I can't believe you finished it in a 2 week deadline! Amazing!
I love the idea of UV detection amulet.
You did amazing job with it.
Hand soldering all these without a hot plate is some truly masochistic stuff
Absolutely excellent work!
Highly entertaining and inspiring, awesome craftmanship and engineering. Subbed!
Some of the best engineering contents ever found on TH-cam. Final product = piece of art😮
Amazing work, really enjoyable, thanks!
That is a gorgeous piece of industrial design. The fact that it requires pretty much every skill that I've personally built over a lifetime (machining materials, electronics design, soldering, software engineering, jewelry design...) pretty much puts this right into my wheelhouse, and now I want to build my own... After all, being a redhead, the sun is my natural enemy.
Not one like that, however, I would loathe to copy someone's designs outright. I need to build one that has a similar function, but goes about it a completely unique way :)
Unfortunately, watching this video has possibly created a bias, so I have to try to do things in a different way :D
This guy is such an inspiration to me. Awesome work!
I had a very similar idea a while ago, congrats for actually pulling it off! :)
46:09 have you ever tried using solder paste out of a fine syringe?
I find it quite nice for small projects like this
Love how deep this goes into the subject. Both the machining and the electronics.
I'd love for you to post more often but in the end: quality > quantity.
The precision of this large lathe is very impressive!
I learned so much from this. And totally understand the idea of small project that... kinda got out of hand. Great work!
You are amazing, and don’t forget it! Absolutely blown away by your intelligence, wit, and skill. I never ever leave comments but I was truly compelled to do so after watching ❤️
There is a camera program that can measure comparator and has a definite number of features that can help in machining your products. It also can conveyer belt check items a separate items
Great project! A nice way to spice them up is explaining things that may not be universal for everyone. I thought about this when you spoke about the DRO that for a machinist is super obvious but maybe not for everyone.
I followed your instructions, built the thing, and wore it all day. Still got a sunburn.
It would have taken me 2 weeks just to plan just the electronics portion of the project. The fact that you did the whole thing in 2 weeks is mind boggling. Also great looking amulet. I particularly like the fact that you went with the same color LEDs. Many would be tempted to mix the colors, but your choice of just yellow/orange is a perfect match for the amulet. Nice sense of style!
I love your chanel. Mixing assembly and jewelry is fantastic!
Great to see you're back.
the moment you showed the tiny brass threaded lid you blew my mind!
that's super cool, I love it
Great video documentation!!!
Bro I have missed you. Glad to see this banger of a video : )
Was referencing your info about how you made your Game Boy emulator a few hours ago; now this comes out? Amazing content! Will always look forward to more
Really like that intro
Ive used a frying pan as a hot plate to reflow solderpaste. Seems to work well, especially on small pcb.
amazing project i would have covered the pcb with laquer of course with the sensor masked out but still phenomenal
I knew I’d enjoy this video, but I didn’t realize just how much I would lol. Loved every second of it! Incredibly creative.
You magical engineering wizard. Look forward to more content!
Fantastic stuff!
Wonderful video, 4 months of editing was obviously worth it
Awesome as always :) I wonder if there's a sensor that has spectral range between 200 and 280nm (low UV-C?)? I'm very interested in detecting germicidal capabilities of UV-C lamps and debunk those that are sold as if they were within that range?
I'm pretty new to this channel, so stop me if you've heard this before, but I can't get over how lovely your voice is. The content is great too, but I could (and let's be honest, probably will) sit here for hours just listening.
I've been thinking of making a protective multi-sensor (UV, CO2/pollution, hidden camera detection, etc...)
Excellent video and content young man. Well done Sir. :)
When This Old Tony meets Marco Reps! Awesome video!
That funky retro 8-bit into was an absolute banger holy shit I was transported to the summer, late 80's, and after using the 16-bit extension to the ISA bus to allow me the choice for an IRQ (10) and DMA (0)m channel...I reboot with crossed fingers and close my eyes as I step into a new age...the dawn of "Multimedia" rises, and a stanky, raw MIDI funky jazz/blues tune plays in 44.1 kHz mono from my Personal Computer. Holy crap, this feels like we are living in the future. Incredible. 🤟🤟🤟🔊🔊
NICE! I've been slowly working on a project like this in my free time for fun using organic material as a resister with copper coils for a sort of manipulative electromagnet. There's so much possibility with this sort of thing. the golden age of wizardry is upon us.
Science, when you dont understand it, it becomes magic, hence those two are the same thing.
thanks for detailed video
Excellent video!!
I watched the whole thing! BRavo. I Dont understand a single thing about IC behavior and code setting or reading. But it was fun to watch. Your narration's are awesome!
Hey, it's me your friend thank you for gift I send you my address to ship./s
This is an awesome project! Very inspiring to make my own gadget (probably 3D printed instead of machined though.) Maybe something to read ambient noise to notify me of when it's dangerously loud since I work with tools a lot. Also, thanks for sharing your frustrations with the "UVB" meter! It's killer when parts blatantly lie about what they can do! Reminds me a lot of when I was hunting for a very precise RH meter, only to find that except for expensive fogged-mirror sensors, basically nothing can get better than ±3-5%.
THIS WAS EXTREAMLY ENTERTAINING AND FUNNY. I HAD MANY LAUGHS TO GIVE AND MANY SMILES TO BEAM TOWARDS YOU ALL. I HOPE YOUR FAMILY HAS A VERY NICE CHRISTMAS
Oh holy crap, welcome back!
Noone:
Noone ever:
Not even Satan:
Mitxela: ...much easier in assembly
I can't help but feel like in the next few decades the things he makes are going to become collectors items. Regardless of obsolescence. These devices are such delightful intersection of art and science.
i know nothing about eletronics, pcbs, machining and doing creative art projects. but i love this channel now. nice explanation on details :D thanks for the quality content. the pcb melt video was one of my favorites, looks like an art documentary about evolution of pcbs and ends on shroon trip (sorry, english is not my native language). edit.. 8:43 🤣😂
Watching this was extremely painful, and I enjoyed every second
great project!
this is cool as hell. subscribed!
