Damn dude, just noticed you've only posted 2 vids and < 10k subs. Your content is pure gold and very, very well explained. I see big things coming your way my guy
If you continue to do such videos where you go into detail even for such small details, I would be so happy to watch more and more. Electricity is not my strong side and understanding more through these in-depth showcase with formulas and practical stuff is so good. Im currently planning on doing a neon sign and I am stuck a bit at how I can power it because I still want to use the receiver and remote control
Thank you! This is exactly what I was looking for. I just wanted to play around with simple lighting for 3D-printed models, and you provided all the basic answers I needed. Cheers!
Fantastic video, very concise. A little too concise, actually. Some additional detail would have been welcome. In any case, it was a nice follow-up to the first sign video. I'm actually printing one right now! :D
@jimmer411 has provided a good answer, but it is also important to consider power loss in some situations, which will change actual current draw and overall life. For example, stepping up two 1.2v rechargeable with a boost converter will take some added mAs.
I guess if you wanted to use mains power instead you could try using the sort of transformer plugs that are usually supplied with mains-powered led strings you find on sale around Christmas. Also, here in the U.K. you can buy a similar product but which comes with dummy batteries. I have two of them which can power one, two or three led devices which use either two or three AA batteries. I can't be sure, but I imagine you could actually remove the dummy battery attached to the wires that go to the transformer, solder a DC jack on the cut end and add a female DC socket to your project (??)
Hello, thanks for the info! If you wanted to power it via a CR2032 battery, would it be possible? Would you need a resistor again, and if yes, which one? Cheers!
Thanks for these videos. I'm trying to power two of those 300mm LEDs to make the length 300mm with 2AA batteries. Any idea why is doesn't work? Thanks!
hi, thank you for this turtual! I made a neon sign, i needed 3 x 300mm led strings. I use a USB connection to power these. I added a 1 x 22ohm resistor between minus. Lights work as they shoudl. resistor gets hot (to hot to touch). Is there a advice to give? I do not have much experience with resistors. shoud i give each string its own resistor? Thank you in advance!.
Thanks for sharing! I watched your previous video and would have loved to make some of these, but now it's too difficult. Is there a simpler solution? Please ;)
So, something was skipped. If you NEED an 11ohm resistor, but you only have two 22ohm resistors, what do you do? or, what did YOU do? For those who didn't see that explanation, because there wasn't one.... this situation happens a lot. You wire 2 resistors in parallel. The math is R1+R2/2=R3, so 22ohm + 22ohm divide by 2 equals 11ohm. US Navy Avionics A School taught this and in the older discrete component avionics once us Navy types were underway and asea far far away where the USPS and FedEx couldn't reach us..... we had to know electronics well enough to do the calculations and build 'work arounds' for parts not on hand.
It would be a little risky if you are talking about directly powering from a D Pin, as @jedandecko5585 mentioned, the mA output is very low. Maybe if you are working with a shorter length, otherwise you would probably want to consider a solution such as using the board's power pins (or an external power supply), and then a transistor on a digital pin as a switch.
@@Andy-t2q5i that is true, max V is 1.2 V. So 2x1.2=2.4 and then step up to 2.8V. Or you can buy ltl better step up and use only 1 battery and step it up from 1-1.2 V to 2.8V, ordinary aliexpress step up modules need 1.2V minimum, so after 20-30% of battery capacity they will shut down. I hope its ltl clearer now, I was trying to give you quick answer. Also take in account that any V conversion is about 80-85% eficent rest is lost, count that lost when you calculate how long your light will last. GL in your project.
The love one from the first video shows its powered but i see no wires. How was that powered and how was it built? You need to make a more clear full video if you can :)
@Landstreicher48 answered this correctly, but in that video I used an extremely small button battery, small enough that it isn't visible (note: not really best because of low capacity).

I love it! I always struggled with these formulas in school, but I learned them all with this video
Glad it was helpful! Thanks!

Thank you so much for this video, I'm working on developing my understanding of electronics, and this helps a lot!! I hope you've having a great week!
Thanks for your feedback, I am happy it was helpful. Have a good one!
Excellent video, dude! Thanks a bunch! 😊
Stay safe there with your family! 🖖😊
Thanks for the positive feedback, take good care as well!
Very nice and simple to digest video and the fact you provided an easy to understand method of bringing down a voltage is wonderful
Thanks for the feedback, happy you liked it! :)

Really nice video. Thank you for sharing.
Thank you, happy you liked it! :)
You make an 11 ohm resistor by putting 2 of the 22 ohm in parallel
Great tip, thank you! :)
I came here to say just that.
You can use 15 ohm register with one 18650 cells . ......
thank you, very informative video, and sound is a lot better
Thank you, I was careful this time! :)
LOVE so much your content!
mega useful..🎉
Incredible! How long do these last??
mah rating of battery used / mA draw of light = run time. So a 500mah battery with a 100mA draw would last 5 hours.
What components would you use to charge those rechargeable batteries in order to be able to charge them via USB ? Perhaps for your next video?😅
I do have a nice module that we could include to do exactly that. Right now, I am just removing them and using the charging station I have. :)
@jimmer411 has provided a good answer, but it is also important to consider power loss in some situations, which will change actual current draw and overall life. For example, stepping up two 1.2v rechargeable with a boost converter will take some added mAs.
Maybe make an episode on how to power multiple strings for longer text. No chance spelling my name with 300mm of that led XD

The 3V battery seems the easiest.
Is that enough power for the LED?
Thank you. How about diming the LED?
Definitely a possibility but I wanted to keep it simple as a starter project for now. Thanks! :)
Can you run a usbc female port to the battery holder so it could be charged without removing the batteries?

So what if I use multiple lights? Same specs?
That’s what I’m trying to figure out, I have no idea what I’m doing and I’m excited to try it out
I was hoping for some ideas on neatly incorporating the battery into the sign
Working on that video next, should have it published soon!
@@nick_the_maker looking forward to that. I just ordered a bunch of the leds as planning to make some light up badges with this method
Is it possible to merge or to connect two words?
how about for cr927 batts?
Lithium can go up to 4.2 volts when charged
Thank you, very good point to keep in mind when calculating.
How do you do letters with a dot, like i and j?
I would imagine printing a bridge that covers the gap you need but could be tricky

Can you power these using Arduino?
No, Arduino power out per pin is 20mA on r3, r4 is 8ma. Also it will overcomplicate project.

Why didn't you use rechargeable AA/AAA batteries?.....
He did, whyen he used step up :) from 2.4 to 2.8 v
(rechargable batteries only have 1,2v and not 1,5v)

GL in your project.
CR2032 wont work as it can only supply couple of mA
The love one from the first video shows its powered but i see no wires. How was that powered and how was it built? You need to make a more clear full video if you can :)
@@wpgcelica It didn't need power because it was made of glow in the dark filament, so it only needed sun. The one of this video yes needs power.
@@Bruns07its definitely lit up. I'll hopefully wait for the channel to reply :)
Watch the video again he used a round cell battery and simple copper strips to connect them, so there was no real wiring
@@Bruns07 Not true. The GITD filament was only because is was translucent, and made the LED easier to see.
@Landstreicher48 answered this correctly, but in that video I used an extremely small button battery, small enough that it isn't visible (note: not really best because of low capacity).
Now make a keychain version....lol
1:27 is it not common for basic electrical knowledge to be taught in school? Most people should not have to be told this.
Too complex for me.
Then perhaps you need more practice. Or maybe you will not be a maker? That's okay, there are plenty of other hobbies out there. Can you paint? :)
