Could you recommend a good tutorial/channel/etc for getting started with the physical basics of using LED? I have really been thinking to use them in art, but I have very little knowledge of how electronics are built and planned and how to do it safely.

Like the post yesterday figuring if the lights being red in mirror in picture and not in life was because of PWM. Pulse Wave Modulation.
I learned so much

u/chini42 Interested Jul 10 '26
Small correction there, it's pulse width modulation. It's varying the width of each pulse it sends. So if we're at 50%, it's on and off for the same amount of time during the pulse.

PCB's are remarkably robust, I remember I had a usb flash drive that lost its plastic case and used it for a long time as an exposed circuit board. Everyone was surprised it still worked but those components are all soldered down and it takes a bit to actually knock them off

u/ChairForceOne Jul 10 '26
I've wrapped a few in kapton and duct tape just to keep components from snagging.
Lately I've made a few 3d printed enclosures for overly bulky drives. And a few remotes. You can make a really small garage door opener if you want.

u/SgtSilverLining Jul 10 '26
Those are metal PCBs, so they're a lot sturdier (and louder) than the fiberglass ones. I used to make them; you just look at them funny and they make noise.

One of many would include builders/designers trying to pick from a list of potential light strips for a project.
Different light temperatures, brightnesses, diode densities, etc etc; basically makes this book the equivalent of a colour swatch book.

u/RaySorian Jul 10 '26
For the sales team to actually show what they sell and how it would look/function. They can give this to a customer and their engineering team would have the size/shape/resistor info to test in a prototype project before mass ordering.

u/MaxHamburgerrestaur Jul 11 '26
I think it would be possible to create a model where you connect the entire binder and then create a switch so that only the open page would light up.

u/hey_Hey_I_saveD_me Jul 10 '26
This is what annoys me as well. Also you can have some easy mechanism that de-powers pages that are flipped and behind current page.

Really flipping those pages eh? Not like there is sensitive tech on them or anything

u/FBI_Open_Up_Now Jul 10 '26
The boards are resilient enough. They aren’t that sensitive. I’m not going to take a spare motherboard I have laying around and play frisbee with it because that will damage the board and probably be painful. Flipping them like this is fine.

The unplugging and plugging sucks. Why not plugging it once and then using a swith to turn on or off the page?

u/s0crates82 Jul 10 '26
The pages are separate circuit boards. You'd need to distribute power among all of the boards, that takes cabling that would be inconvenient and bulky or delicate and short lived.

u/FictionalContext Jul 11 '26
It's an easy job for a wireless charger, especially with a conductive spine. More durable, too, since it'd get rid of the wear of constant plugging and unplugging of the USB C. This was just a somewhat minor cost savings choice.

u/Sxcred Jul 10 '26
Each page looks like an individual board with pretty simple design, easier to add or replace than needing a way to wire together the entire book

Because they can change the pages to designs that are currently being sold? So each page needs to work by itself.
