[@Space_Reptile]

adding a small layer of milky transparent plastic would help to diffuse the LED's and make them more visible when displaying graphics or letters

[@Jett-n-gin]

This is a super good idea! Put a dollop of epoxy over the LEDs and set some diffuser film in it to really make the LEDs blend together and be nice to look at! Would definitely make the random blinks more interesting to look at in my opinion

[@Jehty21]

​@@Jett-n-ginmaybe a diffuser film wouldn't even be needed and just sanding the epoxy would be enough.

[@RD-op6lv]

​@@Jehty21 I think it would be better to flood the LEDs with black opaque compound and then sand it down along with a small layer of the top of the diodes

[@nopelol8718]

It could also double as protection for the LEDs

[@DisorderedArray]

Smoked perspex sheet might work too, one could stick it on with epoxy, and hides the components, makes it look like a black screen, but lets through the light with not much loss. I've used it on much larger LED projects and it looks really nice.

[@user-ix9lx4sp1z]

Given all the precision you've shown in other projects, it's actually really cool to hear you say "lazy", and still end up making a grid of 0201 components work. Your half-assing it looks a lot like the rest of us whole-assing it, or even whole-and-a-half-assing.

The copper wire on the soldering iron is such a useful tip! I'm going to be (attempting) to repair my laptop myself and I was a little worried about if my iron would be precise enough, but that could save me!

[@nikkiofthevalley]

He was only able to do that because there's no pads completely under the component. In a laptop, there's many components that you can't do anything to with a soldering iron.

[@RobertSzasz]

Are there any commercial addressable cob arrays like this?

[@harrysmbdgs]

Pun intended? 😂

[@lost4468yt]

​@@nikkiofthevalleyyou can definitely do a ton of stuff on a laptop with a soldering iron. It's mostly technique. The copper trick is also not the best because it just has so little heat capacity.

[@izperehoda]

I would recommend training on some lesa valuable circuitry before taking risks with your laptop.

[@ThereIsNoRoot]

The stacked PCBs is genius. Really appreciate you showing how the pick and place worked. As someone who also does a lot of LED PCB stuff it's nice to think if I ever need to buy a pick and place machine it's within the realm of reason

As a woman, an electronics nerd and a hobby manicurist: YES PLEASE! The earrings are gorgeous and I'd love to wear a pair even if it just lights up for an hour!

​@ruolbu idkk i feel like someone could definitely do it now with this video as reference

[@mikeselectricstuff]

For stuff like MCUs which don't need the thermal pad for heat or RF, I usually omit it from the PCB - more room for tracks, and sometimes the large pad can make the part float up if there is too much paste.

[@sora2534]

this guy is quite litteraly sitting on a gold mine with these, and he's severely underestimating how much people want them

[@SebBrosig]

In the early 80s when i was about 15 I made some led ear studs, these were a 5mm amber led with the leads clipped short and connected to a 2-transistor blink circuit and battery with thin enameled copper wire. I was surprised that there was some interest by a couple of girls in my class and I sold two. This project is more impressive but there was a wow factor in the day to having a blinking earring too. Being a nerd you can imagine how far I got with those girls...

[@minetech4898]

If it weren't for the battery life, I can see these selling quite well. Looks amazing!

[@fireinahat4]

Just when you think Mitxela has finally reached the point where hand soldering is no longer possible, he busts out the copperwire tip and proves you wrong. I'm now solely convinced humans will never create a package too small to be hand soldered by Mitxela.

[@SpaceMarshalGyorni]

Soldering the two PCBs back to back is a stroke of genius! Really amazing to produce something on a scale this tiny, all in a home lab.

[@ReavoEnd]

A great substitute for protective epoxy is UV glue. It has a similar end result without being a two-part formula, and with a nice 15-25 second cure time. These are always so fun to watch. Thanks for documenting your process!

[@fabiofl]

“Have you ever wanted a LED matrix on your earlobe? No? Well. Let’s make it happen anyway.” This is the most “Marker thing” a person could say.

[@TheDeadlyplatypus]

I’ve done a lot of screen printing ink on fabric/paper and one of the first things you learn to get consistent application is to hold the squeegee at a higher angle to the screen (probably about 75 degrees). This helps you apply pressure more consistently. The screen bowing down to meet your material is your friend! You basically only want the screen to ever touch the surface of your material once as your squeegee passes over. Every time you have to do another pass risks it being aligned slightly differently and smashing the edges of what was already applied. Not only can that make your edges fuzzy but it can leave paste on the underside of the screen, depositing on the next board you pull. I hope this helps! Idk what kind of tutorials exist for solder stenciling but it’s extremely similar to screen printing and searching for technique videos of that could hopefully help you improve your application.

[@oliverer3]

This is very useful advice, thank you!

[@00_01]

Love this content. "it takes 3 attempts before asking for help, it's kind of cute" 🤣

[@kocilis121]

Of course I always wanted a luminescent diode matrix on my ear lobe! The earring projects are so cool, sometime in the future I would love to try to make something like this myself, owning one would be great. Right now though I know only some of the basics of circuit design and don't have acces to some much needed tools

My mind settled on "extremely low cost, 3 wire 32x8 LED display board" - you could be all in on parts for under a dollar and you'd still have 2 i/o pins left over to daisy-chain modules together! Very capable microcontrollers.

If you know anyone with stretched ears, you could make these from tunnels - the various sizes would give lots of options for displays, and the battery could go inside the earring itself if it's big enough.

Brother the rave scene would kill for these.

[@stevefox3763]

A little tip for you if you want to be able to make the leds appear sharper, place window tint film over them, this will hide the individual leds and only show the ones that are lit, adjacent leds pick up the glow and wash it out which the tint would prevent, it would also make filming them a lot easier.
