I wanted to make a video of the assembly of this electronics kit, but unfortunately my cheap camera rig wasn’t cooperating. I translated the manufactures assembly instructions , so I figured I’d post that along with a couple of still pics for anyone who was interested. The kit is all tiny surface mount components, so I would not recommend it as someone’s first electronics kit, soldering those tiny LEDs with can be tricky. The markings indicting polarity on the LEDs are tiny, so I recommend a magnifying glass or a multimeter with a diode polarity tester. The spinner is a lot of fun once assembled and the patterns are pretty. The same manufacture offers a different kit with a programming header, I might try once I get my camera rig sorted out.
I recently purchased an inexpensive timegrapher off of Aliexpress, in order to improve the accuracy of a watch that has been losing considerably more time than my other watches. The included instructions are in Chinese which was less than handy, fortunately there are numerous tutorials on YouTube on using a timegrapher. You can use it with the Android app TICKOPRINT It also works with the Windows program TimeGrapher TG although I had to go into my system settings and adjust the microphone volume all the way up in order to get the windows software to work. If you are still having problems, there is an internal volume potentiometer connected to t he op amp. Adjusting it as pi ctured increases the volume. To get access remove bottom pads and the 3 screws on bottom. Here is a link to the timegrapher guide I am using to attempt to fix my watch.
