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.

[@cezarcatalin1406]

@@MrPhilip796 Ok, that’s actually a good point... maybe we can have a round epaper ? Or... maybe we can have a square amulet...

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...

[@demoniack81]

Honestly the amount of times the published example for even popular libraries flat out doesn't work is ridiculous.

[@KnowledgePerformance7]

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.

[@benfaulder7532]

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

[@Filyx20]

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

[@bitluni]

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.

[@bitluni]

@@mitxela if it wasn't a present I'd probably use hot glue 😂

[@TheRailroad99]

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.

[@Nono-hk3is]

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.

"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.

[@Flixterino]

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.

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 KZbin. 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.

[@spacepirateivynova]

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

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%.
