Ah, another riveting tale of tech DIY 🛠️—because who wouldn't want to waste their time reverse-engineering a #protocol for the 3 people who need it? 🤓 But hey, at least now you can be the #hero who saves us all from the terror of... port 8080! 🎉

Cuối cùng mình đã lắp gần hoàn chỉnh hệ thống tự chủ: Nextcloud, Home Assistant và sắp triển khai Immich chạy trên HP EliteDesk, ổ HDD 10 TB trong vỏ USB. Tủ rack in PLA không gặp vấn đề nhiệt, chỉ cần thêm hỗ trợ phía sau để tránh mặt trước cong. Thiết kế rack có sẵn trên Printables. #HomeAssistant #Nextcloud #Immich #3DPrint #DIY #Makers #Vietnam #TựDo #TechDIY
