That's pretty cool. You might look into getting a hot air rework station for soldering jobs like that. You may find it's both easier to use and renders better results. You'll use paste-based solder, which comes with a big warning about unstable shelf life. I've used paste that's years old without much issue on hobby projects. Hell yes I'd wear that at a festival.
Was going to say this! 100% agree. I still have a syringe of solder paste in my fridge from 2020. Also, get a stencil made for your PCB. It makes it super easy.
Thanks. Actually, I was thinking of using stencil + paste in the next projects. Could you recommend some paste that is good enough and doesn't cost too much?
I will definitely try using soldering paste + stencil in the next projects. Thanks :) By the way, does the stencil thickness matter that much? Or does a thicker one simply allow putting more soldering paste on the board?@@jss331
In all honesty, you really don't need a stencil if you're doing things by hand on small boards. Stencils are used by robotic assembly to spread paste over a very large board very quickly prior to the pick-n-placer dropping components in. Just apply some amount of paste on each pad, it doesn't have to be pretty. When the solder melts, capillary-action will cause the solder to pull off the solder mask and neatly pool over the pad. Even better, capillary-action will center small parts for you evenly between the pads@@NickElectronics
I think it is actually a good idea. However, after giving this design a lot of time to simmer in my brain, I believe the best option is simply using a flat, inexpensive screen. It would give the same result, cause modern screens are quite thin :) When I was working on the badge, aside from the application, I wanted to test 3D printed materials and how accurately dimensions can be printed. Prior to that, I had zero experience with 3D printed parts. I was pleased with the 3D printed parts. At least they are much cheaper than CNC machined ones :)
Yep, an LED display backlight is a great option. But, as always, the human brain only seems to give good solutions after something has been done wrong 😅 Experience it is called, i suppose, hahaha Thanks for watching btw
Very cool idea and execution. I wonder if the LED placement concern (i.e. the localized lighting from below) could be solved or mitigated with a diffusor. Maybe by gluing wax paper or something similar between the sticker and the case or by scuffing up/sanding the case before applying the sticker. Then again, perhaps the varying degrees of transparency of stickers already give you an idea of how well this would work. In any case, nice job. I'm curious to see another iteration.
Hey, thank you for the positive feedback, I appreciate it! 😊 Actually, I tried putting a piece of paper in between, but it didn't help. Also, the frosted case was already sanded a little, but it had a low impact. The next one is going to be better, 100%! 😉
New Version With Fluorescent Paint :)‼

For light diffuser - can you try to use laptop screen diffuser films/layers? it does exactly that - edge LEDs light dispersed into flat screen.

Thevbest project this is fantastic
😁
An another solutions would be an inner layer, exactly how in LCD displays done :)

You sure you meant LED and not S? :D Very fun.
Gonna deliver S later
Those are so beautiful😍

@@NickElectronics Interesting takeaways. I'm looking forward to it.
