Gikfun Christmas Tree 3D Xmas Tree Led DIY Kits 7 Color Flash Circuit LED EK1697

This is a beautiful little kit that is fun to build and nice to look at when finished. I wanted to give my 9-year old daughter a sense of how electronics work and are made and think that this is an excellent set if you can provide a bit of supervision and know how to solder. I was very surprised how quickly my daughter lost her fear of the hot iron and learned to make solid connections. Some of the soldering spots are tight and require a bit of experience. There aren't any instructions but the schematic is simple enough, and everyone who has done a bit of electronics knows that particular circuit. If you have never seen one it will be tricky. I like that there aren't any ICs or other parts that can be fried easily. The board itself also takes a good amount of heat. I am echoing what many have said already and add a couple more thoughts: There are only 3 types of resistors: 10k, 2.2k, 1k. The 10ks are marked on the board. Don't put the top LED in until you have assembled the tree. The long legs of the LEDs go into the square part on the board. I soldered the tree to the base before I screwed the base onto the battery component. It would have been easier to first screw the base to the battery component and then put the tree on top. I loved that they provided 3-color LEDs--although you should expect more of a disco experience than somber blinking.

This kit was fun to build, a bit more involved because of the quantity of parts but that just added to the experience for me. FAR better than I expected! Like a mini disco Christmas tree!

This is a soldering practice kit and I used it to introduce my teen to soldering and basic electronics over the course of a couple hours. The kit is quite adequate quality considering the price and the final product is a fun treat fora job well done. The instructions are lacking in clarity for a novice bu no problem to follow if you have some basic electronics knowledge and have built other types of hobby kits.

I purchased this cute little tree for my husband to assemble for the holidays, he is experienced in electronics assembly and had zero issues putting it together and I think it's quite cute. While the instructions may lack due to the language, there were zero problems if you are able to read a schematic, and that's really the only instructions you would need, even I understood them as an Electronics Draftsman. Those who are new to DIY kits probably would benefit from the English version of the instructions so I do suggest getting them as they seem fairly decent with step by step instructions. The kit comes complete with everything to complete the tree, however it does require you to use batteries or USB cord. Love the kit, would recommend it to those with a bit more experience reading schematics due to the language barriers.

Was the first time I really soldered in years. Used to modify electric rcs when I was younger. Not great with resistor knowledge but this was easy. I jumped in a little too quick and realized there were 2 types of resistors here (1k and 10k) and thought I put one in the wrong spot. There are 6 with an orange stripe and 6 with a red stripe. Orientation doesnt matter. Start with the resistors and put the orange striped ones in the holes marked 10k with an R(and a number).... Then put the red stripes in the other R marked slots/holes. So 3 orange and red striped resistors on 1 board and then do the other the same way. At this point you have 12 resistors installed. Next grab the black pieces that have 3 metal tabs coming out (they're called the triodes). You'll have to figure out which way to bend it as when you combine the tree halves they might bump, but that can be carefully bent back the opposite way if so. After 3 of those go in the spots with the 3 slots/holes do the other board. Next is the elestolytic capacitors which have a positive and negative so orientation does matter. Like the LEDs the long side is positive. Install these the same as everything else, using 3 per board in the 3 spots with 2 slots/holes near the bottom of each board. Next up, the most tedious part. If you got this far you know how to bend wires and snip excess off while soldering things onto the board. Well goodluck! Go and solder 18 LEDs oer board ! When you're done feel awesome. This is where I lost direction eventually. I installed the 5v adapter and the battery pack to the base and the tree to the base and no matter what I tried only 1 side would light up and the 5v killed it everytime. Maybe it was shorting it out. I just ended up hacking the hole thing with just the battery pack adding 2 extra wires to power the both sides of the tree/boards simultaneously. I figured after all that I wasnt really gonna sit there using my pis power to run the thing for that long and just installed a fan hat on my pi anyways. So for learning simple soldering and having to follow through with a lot if peices, this makes this kit INCREDIVLE AND INVALUABLE for learning whether you're getting it for your 12 year old or yourself at 50! It's so cool when it's done!

I got kinda hooked on these. Built 3. Just ordered two more. Fairly sturdy when constructed. Instructions are basically a sheet of paper which may or may not reflect the correct bill of materials. The PCBs are well labeled, though. Nice and bright: makes a nice ligh to take along at night when walking the dog. Update: Ordered 5 more of these since September 2022. One worked and the next two I’ve assembled are duds. I’ll probably need to QC the components before I assemble the remaining kits. Boo! I can’t recommend this product anymore.

This is a simple and fun kit to assemble. The instructions are pretty good, as it gives you a parts list, a circuit diagram and test tips to ensure functionality. As long as you read through first and understand the procedure this kit should not be o problem for anyone. I now feel like doing more kits like this 👍🏾🤓

Anspruchsvoller als man zuerst denkt. Etwas Löterfahrung sollte vorhanden sein. Die Anleitung und der Druck auf der Platine genügen vollauf.

Bought for a little cracker present for my dad for us to make at Christmas. It was really easy for a beginner like me with a bit of support from him. Very happy with the outcome!

Alles bestens

Ein toller Bausatz. 5 Sterne hätte ich gegeben wenn anstatt des Schaltbild ein Bauplan dabei gewesen wäre. So musste Papa bei der Widerstand Auswahl und polaritsfindung der LED helfen. Aber dann leuchtet der Baum in allen Farben
