AA Battery Powered Light String to USB Power Conversion

How to convert a battery powered light string from using AA batteries, to using a USB power source. I used a 1/4w 100 ohm resistor.

this is literally the best video ive ever seen to cover this subject.

WOW.... love the clear and specific instructions. Plus thank you for the high quality resolution of your video.

Very good. Very thorough. Thank you very much!! I wanted to hook up some Xmas tree lights to a power cord an I was looking for ways to step up (transformer, etc). I never thought of using an USB. Ingenious! Thanks again.

this is a SUPER professional video for those who want to do it the RIGHT way. but for me don't have all that lol and with the closing of radioshack I don't have easy access to resistors and desolder and whatnot. i just gamble on the extra 0.50v not frying my light 🤣

Ok. Is there any way to turn 5 different lights into 1 USB powered light? They are all 2AA and I'm sick of switching them on and off one by one. Please be kind to this old lady since she knows nothing about electronics, but willing to get all the parts and tools to give it a try if that is at all possible.

Oh... So it requires a resistor. Haha! Im just trying to do everything myself without much knowledge about electricity and stuf.. But thanks to this.

Thanks for a great video! Question: does the orientation of the resistor matter? In other words, does it matter which end of the resistor goes on the circuit board versus which end gets the power from the USB cable?

[BluJns]

I would love to switch multiples on all at once! This was the best instructional video I've seen!
How does one formulate strength of resistor?
Direct, Easy to follow.

Hey there, a very interesting vid thanks for sharing! I have a small water fountain pump. I would like it to operate on batteries instead of by a plug, the opposite to this video. I have cut the plug off and there’s two copper wires, would I need to somehow connect the two wires to a battery capacitor?

Thanks in advance!

Well done, and this is a good video to teach us DIY our device

[non_binary_deus]

Thank you for this video 💙 and if my garland has 4.5v, I just need to properly solder the + and - to the USB?

[part]

Way to much effort! But nicely done because who wants to use 100 packs of batteries lol. I never soldered in my life and omg o really want to buy a battery powered statue but convert it to plug power. Is soldering straight forward or takes long to learn

[zcubedmusic]

Thats a really nice camera quality, it helps alot for these small electronic videos so thank you. Also, this is a much cleaner way to do the same thing I was trying with a step down converter that kept overheating so thanks for that too. I am going to order some resistors now and give it a try on my EL light strips that have almost the exact setup as your lights.

[anthonymatthews]

Thanks man. Really nice job and well shot video.

[jorgeRodriguez-fuqi]

Dude, I love the way you explain and get to point and teach!!! Im not to smart but I think I can do this!! Please post more!!! Also what was that thing (Recestor)you put into the Neg part, , like how does that work??

[sandrachandler]

Very good video, thank you. Your clamp is really great, I would like something more stable than the helping hands stand, what is it?

[GalacticVoltrix]

How did you come about your calculation?

[groundhog]

I'm sorry your video is excellent I just had a question about the resistor

[TheCludo]

nice, i need to do this now to my doom eternal collectors edition helmet wich has lights in it

[fancyjen]

Do you need a resistor if you’re connecting it to a 3V wall adapter?
