LED source


#1

I want to make my own light bases, but not deal with the LED part. I think I found a decent LED strip source and thought I’d share. Forget to mention it’s free shipping too :slight_smile:

Edited to add: I just noticed it says “$3.99” in the link below. I didn’t pay attention and ordered from the US warehouse and paid $5.67. Apparently if you purchase from the Chinese warehouse and are willing to wait on shipping, you get the lower price.

You’ve got to be kidding? What a steal and a find!


#3

Thanks for the share!
Wonder how much the controller and remote are by themselves now.


#4

These? Looks to be about $2.75


#5

this is all great info!

I wonder how many LEDs this can run at a time.
I know with my regular wall plug strip if I turn up the brightness too much it will start flashing. I assume because it does not have enough power to run the whole strip

Oh hey! Look at that! Thanks!

For what it’s worth, I bought an LED “can light” (to use as a backlight against the wall behind TV when watching in the dark) about 8 years ago - it uses that exact remote! And it still works :slight_smile:


#9

how long is the strip?


#10

The one in the video is .5m. The strips come in .5, 1, 2, 3, 4 and 5 m.


#11

I think you mean m as in meters :slight_smile:


#13

I did :slight_smile:


#14

You can get those led kits at Home Depot now, not that cheap but still available locally.


#15

Or Amazon Prime, cheap and tomorrow :slight_smile:


#16

Oh man, I didn’t see them on Amazon and I’d rather buy from them. If you have a link to the preasymbled strips, I’d love the link.

Here’s some of what I’ve been buying from them:


Connectors so you can cut the tape & use pieces:

Thanks. I’m pretty lazy though and was looking for the pre-made strips. I just want to be able to make a base and stick the strip in without soldering etc. I haven’t been able to find them on Amazon. The ones I ordered made it to my door in less than a week so it wasn’t too bad.


#19

You can get shorter ones - I just get the big reels so I can cut off how much I want. The shorter ones have the ends already wired in (4 pin connector) that plug into the controller - just make sure you get the right controller for the wire you get. The RGB ones have 4 pins so you can change colors. The single colored versions have 2 or 3 pins depending on what the controller will do to them (if there’s a controller at all).


#20

Does anyone know if I can use Arduino to individually address each led on a strip? I have a project in mind where I need to be able to control which LEDs turn on. Thanks.

Yeah your best bet is to go to fastled.io. That library supports a huge array of LED types. I typically use 3wire style (ws2812b etc) because it makes soldering easy when you have a lot of strips in a project, but if you’re only doing one strip the 4 wire systems are generally better performers (apa102 etc).

The fastled library and forums are pretty great.
