Always appreciate the monumental amount of effort you must put into making these vids. 👍

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.

"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.

Welcome back Mitxela, so glad to see you once again ;)

This an amazing little project! Art, science, machining and code, you've got it all!

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.

@mitxela

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.

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.

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.

And here i thought KZread is again going braindead and suggesting new-age WooWoo like wireless ESD-armbands, but this was a nice idea and project.

This looked like an insane amount of work and I can't believe you finished it in a 2 week deadline! Amazing!

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 KZread. 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.

please tell me youre making more videos like this... this brought me a joy and peace that other channels simply do not have

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.

This is the weirdest ASMR I've ever watched. But it works.

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.

Yooooo mitxela! Wow, I can't believe it's been 7 months, so happy to see another upload!

Some of the best engineering contents ever found on KZread. Final product = piece of art😮

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!

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.

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.

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

I followed your instructions, built the thing, and wore it all day. Still got a sunburn.

Happy to see the manual isn’t overlooked. It’s the icing on the cake for me.

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.

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%.

32:19 When you include the circle (and use it with this context) its called a pentacle. basically, the symbol of protection you are talking about is the pentacle, which is a circle around a pentagram (the pentagram is just the star). Its the inverted pentacle that is associated with evil practices because of the belief that inverting symbols of protection or symbols of good would also invert their meaning. this has clashed with other ancient believes though, so its not 100%. For example, the inverted cross is used to symbolize an inverted messiah (evil messiah) but Catholics also use an inverted cross to represent St. Peter and humbleness because St Peter was crucified upside down on request that he not die the same way as Jesus. Basically, any Catholic who has studied religion for more than 5 minutes knows that a pentacle is just an ancient symbol of protection, generic faith, balance and its the inverted pentacle that is meant to portray the opposite of those things. Also it its not clear, an inverted pentacle has one point facing directly down, while the traditional pentacle has one point facing directly up. why is that? i have no idea.

as a chemist I find it cute how you plated the brass with so little gold. I am used to obvious changes.

I've been thinking of making a protective multi-sensor (UV, CO2/pollution, hidden camera detection, etc...)

Nice project! I see two possible easy improvements: - high brighness green LEDs - drop of a clear epoxy over the circuit board to make it a bit more protected, but still thin enough to not cover the sensor

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!

I feel that „oh gooood“ panic when it comes to threading. I did an internship where I did lathe work a bunch and I always hated threading. I think I legitimately got nightmares about missing some crucial step and accidentally ruining the workpiece or break a tool.

The Bob Ross of electronic engineering. Just beautiful.

Good job. I already have a few suggestions on how to make it better, but I'll keep them for myself since nobody asked. 😀

24:34 "I'd like to think there are a few jewellers watching, and cringing so hard that their teeth melt" I can't believe you've called me out like this... (also solder likes to follow heat, so if you use a flame, try heating from the opposite side next time and it will be less likely to blob on the side! :D )

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?

OMG, the parting tool! Anyone who's done it knows this. Earned you a sub. Your skills are scary my friend. Keep up the great work.

What a cool and useful amulet! Loved this project

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.

That's really interesting. Why do you cover the lathe's bed to keep the abrasive dust away? Will it break or deteriorate the lathe somehow?

@Nimphious

2 жыл бұрын

The reason the abrasives work in the first place is because of the hardness difference between the abrasive medium and the material you're working. It's not indestructible though, so as you work with it small pieces of abrasive will break off and fall into the ways of the lathe. This is problematic because that's a precision ground bearing surface that the lathe parts move across, and if there is abrasive powder there (which is harder than the lathe parts) then they will abrade the bearing surface and ruin the precise flatness, which will cause problems like the toolpost or tailstock carriages binding up while you're trying to move them back and forth. The reason most metal chips finding their way down there isn't a big problem is because the softer worked metals are typically not harder than the surface of the ways (though when the metals *are* harder, similar precautions need to be taken.)
