DIY Electronic LED Christmas Tree Kit - Gikfun 3D Xmas Tree

[@garyduensing3495]

Just bought one of these for my son. And there isn’t any instructions 🤷🏻‍♂️

[@RudaroAmaro]

I bought one of these after watching this video and have just finished building it. I was able to finish this build without any major issue. Thanks to Backofficeshow for the helpful guide! Helped me out big time.

[@backofficeshow]

That's wonderful! They are pretty awesome, it's a fun kit

[@Kiwagwar]

Oh so first time soldering and messing with these kind of stuff. I i got mine without instructions so, here im, learning

[@IanSlothieRolfe]

The word "Triode" was used by the inventor of the vacuum tube triode and is from a Greek word that means "3 ways", or a junction where three roads meet. Therefore technically a transistor is a triode since it it a junction where 3 currents meet (at least as much as a semiconductor diode that inherited its name from the vacuum tube equivalent) although historically the English speaking world doesn't really use the word that way. I imagine its a Chinese-English translation thing, but it does seem rather quaint. Its a bit like the way a lot of Chinese kits refer to 7 segment displays as "tubes". I built one of these kits a few weeks ago, its very bright but does burn through the batteries a bit, so I power mine from a USB charger these days!

[@backofficeshow]

That's very interesting, makes sense

[@2010stoof]

I need a triode experience with some ladies 😂😂😂

[@lars309]

I'm confused, what did you first do to correct only one side was getting power? I have the same issue and tried rotating the tree with no luck

[@GeilerGelber]

Nice tutorial, I didn‘t get any instructions with mine and the one on the website is so old, that there are parts in my kit, that are not in the instructions, so I had to look up a video and found yours. Only criticism is, that you didn‘t put a warning in concerning the mismatch with + and -. I followed along and now I am stuck because I don‘t have anything to desolder…

[@Justanotherbeautifulday]

How many C or F should my soldiering iron be at? I have this same tree.

[@Fluxtime451]

I just had a scare doing the leds . After checking the led worked , it stopped working once soldered in . I thought I bent them too hard or the heat of soldering . Realized it didn't test positive once soldered into the circuit ...

[@backofficeshow]

Phew!

[@EpicGamerNC]

That was fun to watch! You must be great at parties. Love your personality!

[@backofficeshow]

Thank you for your kind comments. To be fair, everyone is happy assembling an electronics kit!

[@TheDiabeticWay]

Thanks for the video very helpful and its nice to know your talking to yourself like me :-) lol Just wondering on your soldering skills, i changed mine over to the one you have and found it a lot quicker at it heating it up just not sure what temputure you have yours? I set mine to 400c which it may b etoo high? thanks! I want to try to do a few of these for Old people home for there Christmas Dinner if I can do them!

[@backofficeshow]

400 is a little bit too high. You might find that the solder will oxidize at that, maybe you'll find a sweet spot between 250 and 300. It does depend on your solder to be fair and often the manufacturers do say what temperature they melt at.

[@2010stoof]

My kit came with 3 different colors of LED. Yours are way better. Ill grab one of the one you linked. I like it better. Mine just go red green blue in order. I found it easier to screw in the battery holder before soldering to the base. Those little nuts suck between the trunk and the power and the switch

[@backofficeshow]

You're reminding me that now is a really good time to start getting in those Christmas electronics projects, every year I plan to make my my own LED ornaments, and every year I fail to do it

[@2010stoof]

@@backofficeshow yeah I found the trees for a good deal on Amazon for $4. They were labeled 7.99 but right under said 50% off so I'm glad I read the listing. I have like 10 to make lol. I want to do the red round ones but can only find them for $17 for 2.

[@angelortiz1936]

Hey just finished mine and it won’t light up , the batteries get super hot even though led don’t light up , I’m a beginner, would appreciate ur response

[@jarnold1513]

Great video. LEDs 7-12 don't light up on card A. Any ideas what I did wrong?

[@backofficeshow]

I would suggest double checking the polarity of those particular LEDs

[@jarnold1513]

That did it, I had one LED with the polarity reversed. Thanks!

[@backofficeshow]

Christmas saved 😂

[@juanmacias5922]

haha this was pretty awesome to watch, Merry Christmas!

[@backofficeshow]

Thank you so much! It's a good way to start the holiday season. I kinda wish I bought several to gift!

[@juanmacias5922]

@@backofficeshow Ooooh! That would have been a cool gift! I guess there is always next year. :D

[@backofficeshow]

Next year I will design my own for sure!

[@KodySalad99]

so my kit is a little different than yours, and my instructions are in chinese... Got most of it figured out, but I didn't realize until I was done that I soldered every. single. LED. on. backwards...! Any hope to get this to work, or am I SOL?

[@tonyjones629]

what is the name of tool used to make the wires on the resistors bend ? Thank you

[@backofficeshow]

I 3D printed it, but you can buy similar: thepihut.com/products/resistor-lead-bending-tool

[@TheDiabeticWay]

@@backofficeshow Anychance I can get a printed one from you?

[@anyzer2659]

nice video, and merry Christmas

[@backofficeshow]

Thank you, wishing you the same! 🎄

[@idontcare23-jf5pp]

How do you know what arr 150ohms vs 10s

[@BenjaminRains-d3o]

Are “solder bridges” always bad? A few of my components have the solder touching both pins. New to this. Thanks in advance

[@backofficeshow]

Absolutely, that will create a short. Best to clean them up

[@BenjaminRains-d3o]

@ I thought I failed at this kit for no reason. But I learned something!

[@bagnalldave7365]

providing you use non conductive adhesive flock ought to work

[@backofficeshow]

I quite like the idea of iron filling flock, that would be interesting!

[@sinnedam]

I’ve got it all working except my top light. Not sure what I’m doing wrong.

[@90sArcadeKid]

The top light also has positive and negative position.

[@Mr_LANU_]

Do you have a link to the STL of that resistor pin bender?

[@ImNotADeeJay]

just finished mine, but In one of the PCBs three LEDs in each side won't light.. what could it be? Thanks

[@backofficeshow]

Could it be related to their polarity? Perhaps you can remove one of the LEDs and reverse it

[@ImNotADeeJay]

@@backofficeshow the ones not working are in the exact same positions in both ends, much of a coincidence... but thanks!

[@backofficeshow]

Maybe chuck for a common termination for those, like at an IC or resistor

[@supersanset]

Could you share the manual instruction link?

[@backofficeshow]

Sorry, I only had the paper version that came with it, and it's disposed of now

[@retrogamereviews7323]

Weird issue on mine, they all light up, but very dim....any idea what could be wrong?

[@backofficeshow]

Could be a short somewhere, I can't really recall the circuit, but you could possibly have a resistor where a capacitor should be

[@thedutchretrogamer]

'nice kit

[@backofficeshow]

Thank you!

[@robertjames9278]

hi, as they say, if all else fails, READ THE INSTRUCTIONS!

[@backofficeshow]

NEVERRRRRRRRRRR

[@weromontiel]

Mine didnt dinky dinky dink 😢

[@backofficeshow]

You need to check it over once more, you still have time before Christmas!

[@tonalaxis]

Bah Humbug!! JK merry fudging xmas!

[@backofficeshow]

You love it really!

[@tonalaxis]

@@backofficeshow btw the link for the UK amazon is for the other version with the non rgb leds.

[@backofficeshow]

On no, I didn't realise that. I will correct

[@tonalaxis]

@@backofficeshow ordered one, might slow down the twinkling a bit.

[@backofficeshow]

Will be interesting to see how you achieve that
