+In this post I will briefly describe my build of an AllStarLink node. For this, I used the following parts:
+
+ * Baofeng 888s
+ * CM108 USB soundcard
+ * Raspberry Pi 4 + case
+ * two buck converters, configured 5V and 3,7V output voltage
+ * metal enclosure
+ * power poles + mounting plates
+ * ethernet jack
+ * [Waveshare LCD1602 RGB Module](https://www.waveshare.com/wiki/LCD1602_RGB_Module)
+
+I will not go into great detail here since all modifications are described in other places. Please consult the following links:

+Please ignore the two audio transformers. I planned to install them but went with a transformerless build in the end.

+Here is the modified sound fob as described in the above link:
