LED-Heart (LED-Herz)

The last version of my design had an error i made in the Layout-program. So i reordered the five PCBs with an updated Layout. The quality of the PCB is perfect, they are easy to solder (i only use "old way" of circuits, no SMD). The production and transport-time is very fast, there is no need to spend more money for a PCB that is produced in your country. What i have learned? Just use the tools to check for errors inside the PCB-editor before ordering a PCB. When using an Autorouter, this is also needed, and its a good idea to alter the autorouter-output by moving some lines to get a PCB with less small distances between nets.
