Received in good condition and in a timely manner. Haven't tried anything with this kit yet but have built a similar one in the past. I would recommend omitting the speaker as the music becomes annoying after a short period of time.
Nice kit. Interesting to build and play with. You need to be fairly proficient at soldering to successfully solder the surface mount chip and other small surface mount components. I reprogrammed the chip to have some different LED effects and music. I made a video about it and uploaded to YouTube. If you search on YouTube for octagonal star kit, you'll find it on my, ceptimus, channel.
I was alarmed at the absence of instructions with the kit. I was able to find a link in "Customer Q&As". (http://myosuploads3.banggood.com/products/20230910/20230910013202LEDstar.docx ). The maker/seller could include instructions, or at least a note with the link.
Nice kit.
Easy to build, good soldering practice
Kit comes with no instructions but went together easily. I would probably recommend to not install the speaker as it is annoying. I drilled a hole for a keyring to mount on a tree.
You need a small iron tip for this one as you are dealing with smd components that are tiny. But if successful it's worth the effort. It's just a shame that yet again there is no instructions so its a guessing game to work out what the buttons do.
