Frequently Asked Questions (FAQ)

Q: What power sources can I use?
A: A micro-USB (4.5–5.5V) port is included in the kit. You'll need a USB cable, but any micro-USB cable you have available (e.g.: phone charger) will work. You can also supply power via batteries or any other 4.5-5.5V power source which can be connected to the “BAT” terminals available on the circuit board. Our instruction manual tells you how to do this, but please Contact us if you need any further guidance.

Q: Do I need previous electronics experience?
A: No. Beginners can complete this kit following our illustrated instruction manual. It uses only through-hole components which are easy to solder—the main challenge with this kit is proper alignment and soldering of all the PCBs together at the end of the assembly process, but our manual covers this process step-by-step with photos included.

Q: Is this kit easy to store so I can reuse it every Christmas?
A: Yes! Once built, your LED Christmas tree can be used year after year as a delightful Christmas decoration. Simply unplug it and store it wrapped in some bubble-wrap, craft paper or any other protective packaging you have available.

Q: Is the Christmas Tree safe to be left on for prolonged periods of time?
A: Yes! The Christmas Tree uses very low power and only draws 0.2 amps. It does not produce heat during use and is safe to leave on for prolonged periods. However, as with all electrical equipment, we still recommend that you power the tree off when unattended (e.g.: if leaving the house or going to bed). If using with a USB cable/plug, please refer to that items manufacturers manual for safety considerations.

Q: Do you have an acrylic display case available for use with this product?
A: Yes! While it's not listed on the product page, we do supply a clear acrylic case for this item—the case can enhance the appearance of the tree while also protecting the electronic components from damage. If you're interested in purchasing the case also, just Contact Us to request it.

Christmas gift

I was pleased to receive the led Christmas tree for my grandson to put together over Christmas. Seeing some of the reviews l am hoping my grandson can manipulate the small size , and that all the bits he needs to put it all together, is in the pack . I must admit l agree with the having to print out the instructions is a nuisance, as l don’t have a printer , so had to seek help to print out all the pages , but l guess it would be too large to fit in the package to be posted ..

Hi Elizabeth, thank you for taking the time to leave this review — we really appreciate it. Your reasoning is correct: if we were to include 16–22 page A4 manuals in the kits, the package size and weight would become too large, heavy, and expensive for us to be able to ship for free, so customers would lose the free-shipping benefit.

Also, keeping the manuals digital means they are continually updated with tips, advice, etc. as we receive feedback from customers. Most customers are happy to view the manuals on a phone, tablet, or laptop, but of course we understand many people may be buying these kits to get the kids away from screens.

We're always happy to provide a printed copy of a manual for free — we just require postage to be paid by the customer. If your grandson runs into any difficulty when it comes to putting the kit together, just drop us an email or use the Contact Us link on our site — we offer free technical support for customers who have purchased kits from us.

Laughable

This kit was absolutely awful! The directions (what little there were) were entirely in Chinese. A lot of tiny, unidentifiable parts. There is no way an average person could put this together. I tried to make sense of it all and threw it all in the trash.

Hello Danette, thank you for taking the time to leave a review. The 16 page English instruction manual, packed with photos and illustrations and explanations of the circuit and how it all works, was emailed to you after your order was processed, but it's evident you missed the email. Wtih the instruction manual, almost everyone from 10 years and up could easily build this kit. If you haven't already built it, please just check for an email from us with the manual password. Feel free to reach out to our email (info@thesciencehut) or just use the Contact Us form on our site if you need anything else.

7 color Christmas tree

I had an absolute blast building this tree, my only complaint was there was really no instructions on what to do. It also didn’t help that the piece of paper it came with was in a language I can’t read. Yes it was pretty much self explanatory until you got to adding the lights on. I wasn’t sure if you were supposed to have them all on the same side or alternate sides, or even have them at different lengths.

Hi Ben, thank you for taking the time to leave a review, we really appreciate it. It's probably a bit late now as it seems you've already built it (and well done for doing so without any instructions), but we have a 16 page manual for this kit. We emailed it onto you after your order was processed but perhaps you missed the email. You can still access the manual anyways which answers all your questions above, simply search your emails for an email for us containing 'instruction manual' in the email title to get the password to open the manual. Note that all kits we sell have a similar detailed instruction manual and all can be downloaded from our downloads page: https://thesciencehut.com/manuals

Cute kite

I bought this as a STEM Christmas gift for one of my granddaughters who is into bling more than physics. The only issue I have is the instructions are in Chinese. I have enough experience that the schematic drawing should suffice. Otherwise, the kit looks awesome!

Hello Scott, thank you for your order and for taking the time to leave your review, we really appreciate it. Perhaps you missed it but the password for the detailed English instruction manual was emailed to you after you placed your order. You can download the manual from the following link: https://thesciencehut.com/manuals - the manual is packed with photographs and STEM learning content. I have asked Customer Services to forward the email with the password to you again in case you may have deleted it. If you need any further help, please contact info@thesciencehut.com
