Arranging and Soldering LEDs in Series (RC Tricopter Project)

[@lipinghe40]

Awesome video, thank you and GOD bless.

[@TheJahn1]

Thank you. So far all the resources I've seen freak out about precise numbers, good to know I've got some room to play. :)

[@MathTutorVideos]

Great video! Very interesting. I'd never even heard of or seen heatshrink before. Pretty cool concept.

[@Mark1Mach2]

Nice job

[@orglee]

Yes I do like this. :) I have small suggestion for you. Make those calculations on larger sheet of paper instead those small yellow paper stickers.

[@JonProce]

I will definitely do it all on one sheet next time! Sorry about that.

[@Bakey154]

thanks a lot that post it note sesh helped so much

[@siverthalvorsen605]

Tahmk you for the video👍🏻 you really helped me

[@louiscastero6566]

Thanks for sharing Jonathan that was a nice clear video in Soldering LED in a series. *what if i wish to add on series of other color LED (Red), meaning mixture of 3v & 2v Led in a series? And how does that work. Thank you~

[@MathTutorVideos]

Rather than 3x 3v...it would be (2 x 3v) + (1 x 2v) = 8 volts rather than 9 volts. The rest would stay the same.

[@TogiMaybe]

Great vid, helped a lot! Quick question...what was that black stuff you sealed around that thing with the lighter around 5:48 ? I stripped the end of a molex to fan cable and soldered a pre-wired LED to it and was concerned about leaving the wires partially exposed.

[@JonProce]

Tōgi it's called heat-shrink tubing.

[@TogiMaybe]

Thanks dude!

[@luhego2000]

Love it please do the math on the large paper thanks great job

[@JonProce]

I will definitely do it all on one sheet next time! Sorry about that.

[@luhego2000]

thanks if can do some more it will very helpful

[@justingreene6805]

I want to add about 300 LED's to my model train layout. What type of power source should I use?? How should I set the LEDs up in series,,

[@justingreene6805]

Question ^ ?**

[@JonProce]

Justin Greene I'd recommend you use LED strips if you can, they're way easier. The power requirements will depend on the brightness of the LEDs.

[@tanishgupta5]

If I use 4 led’s how many ohms should I take

[@desalbrecht6127]

None. Each LED is rated at 3.2 volts. 4 X 3.2 = 12.8 volts.

[@MohammedRiad]

if i want to connect 100 leds (3.3v each) in series what should i do?

[@JonProce]

Hook them up to a 330V supply (and then realize that's not realistic so wire them in parallel instead).

[@MohammedRiad]

Jonathan Proce what if i want to use 220v AC?

[@JonProce]

Mohammed Riad use an AC to DC power converter, like a computer power supply (PSU).

[@MohammedRiad]

Jonathan Proce ok thank you very much

[@tylerbowers6378]

Lol best reason. Because I can

[@cleon169]

did you ever get a 3d printer?

[@JonProce]

I have two!

[@cleon169]

Wow. What are some of the projects you've been able to do with them?

[@JonProce]

Honestly they're pretty much only good for stuff like this, hobby parts, rough prototypes. Even the best printed parts are not very strong and the finish astethics are so-so. There are lots of applications but they're certainly not as magical as people like to think. A lot of thought has to go into if and how something is to be printed.

Sorry man to much numbers for me
