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:
* [Idiot's guide to building an Allstar Node on YouTube](https://www.youtube.com/watch?v=7L5FZrcyw7M&list=PLePPJqvMoBbbmeAebTykCfmeaaRuqK5DG)

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:

A first test with the RPi and the buck converters built in:
