I designed a very simple power converter for the snow flake decoration. The snow flake boards require 3.3V, a voltage which is not commonly available in a household. Therefore the power converter takes 5V USB power and convert it into the required 3.3V. There is no fancy circuit inside of this box, lazily I simple…

Snowflake Component Side
Today I show you a little bit longer video about the assembly of the component side of the snowflake panel. Compared with the very small 0402 LEDs (1mm x 0.5mm) on the front side, the component side contains just regular 0805 resistors and capacitors. The first part of the video shows how I apply the…
Snowflake Assembly Video
Here a quick video of the snowflake assembly. It shows the assembly of the LED side of the panel using hot air. The assembly went without big problems, except there was a little bit excess solder on the pads. Therefore the LEDs do not lay perfectly flat on the board. More Snowflake Posts
