Raspberry Pi OS (RPiOS) Trixie (13.1)にupgrade<\/a>したRaspberry Pi 3 Model B (RPi3)のRTSP (Real Time Streaming Protocol)視聴はその後も快調です．<\/p>\n\n\n\n

しかし，時々 “Low voltage warning”が表示されるようになりました．<\/p>\n\n\n\n

これに関しては心当たりがあります．RPi3は現在リビングに置いていますが，リビングにはワンコがいます．ワンコの毛をRPi3のクーリングファンが巻き込んでファンの電流が増加したのだろうと推測し，見てみたらその通りでした．<\/p>\n\n\n

もう何年もほったらかしにしたように見えますが，リビングにもってきたのはRPiOSをTrixieにupgradeしたときですから，ちょうど１か月前です．<\/p>\n\n\n\n

部屋は毎日Roombaで掃除しています．毎日なのに驚くほどほとんどワンコの毛のゴミが取れます．ですから1か月でこの程度は不思議ではありません．<\/p>\n\n\n\n

今後のことを考えて，ファンレスのケースを使用しているRaspberry Pi 3 Model B+と置き換えました1<\/a><\/sup>それがもともとのフォーメーションなのですが，Trixieにupgradeする手順の都合で，入れ替わりました．<\/span>．<\/p>\n","protected":false},"excerpt":{"rendered":"
