아래는 안되는 왜 한지 모르겠는 뻘짓

--force를 주고도 한번에 안되서 여러번을 하고 나서야 되네..

stop 하고 나서 된건진 잘 모르겠다.

그리고 여전히 gui로 켜지는건 달라지지 않았다 ㅠㅠ

centos8.2는 minimal로 설치해서 그런가 virbr0 가 안생기더니 풀버전으로 설치했더니 생기네.

libvirtd 데몬으로 인해서 생기는 녀석이라고 한다.

[링크 : https://fliedcat.tistory.com/167]

8.2-2004 에서는 minimal 버전이라 그랬나 10기가에서도 깔렸는데

8.3-2011 에서는 10GB 밖에 안되니 용량 늘려라고 진행 자체가 안된다

그런데 8.2 에서는 minimal이 있었는데

8.3 에서는 왜 minimal을 제공하지 않는 걸까?

+

virtual box 에서 centos8.3 설치하니 네트워크가 아노딘다.

virbr0가 잡히고 enp3s 어쩌구는 ip를 못받아온다. 멀까?

+

그래픽 컨트롤러가 원래 VMSVGA 였던가?

이미 닳아버릴대로 닳은게 보이네.

원본에서 크랍

짧은 거리를 오가면서 저항값이 바뀌는 구조인 듯.

로터리 저항으로 된 건 큰부품이고

이건 높이가 낮아야 하니 저런식으로 FPCB에 저항막을 붙이고 갈려 나가게 해서 내구성은 어짜피 발바닥인 듯..

클릭은 하단의 흰색 부품이 FPCB에 실장된 스위치(위 사진의 정 중앙 은색 부품)을 누르게 되어있다.

전투력 느낌인데 -_-

100 밑돌던 시대가 어떻게 가능했나 싶을 정도로 정말

이제는 이게 기준인가 싶을 정도 ㅠㅠ

조이스틱만 5천원 정도에 판매를 하고 있고

2개 + 공구(Y/+ 드라이버 및 핀셋) 해서 1.6만원에 팔고 있어서 낼름 구매

(공구 가격을 좀 남겨 먹는 느낌이지만..)

조이콘 수리기는 많이들 있어서 대충 보고 따라하는데

의외로 조립이 쉽지 않은 구조에 깜놀.

(전용 지그를 가지고 조립하지 않으면 조이스틱 부분에 눌려서 붕 뜨고 난리가 남)

12:47 ~ 13:00 이니까

대충 각잡고 수리하는데 15분 정도는 걸렸네(사진 안찍고 하면 다음번 수리는 10분이면 될려나?)

700은 안넘고 있어서 많아야 700 막 진입할 줄 알았는데 순식간에 1000을 바라보네..

크기가 차이 많이 나는 것 같으면서도

숫자 차이 (12인치) 치고는 그리 크기가 차이 나지 않는 느낌?

(모니터로 쓰고 있으니 일단은 컴퓨터 카테고리 ㅋㅋ)

1. 빨래 세통

옷 + 옷 + 매트 커버 2개

2. 청소

얘는 무한반복..

3. 닌텐도 스위치 방탄필름 교체

4. 조이콘 왼쪽 조이스틱 부품 교체

5. openELEC + rpi2b + CEC

- openELEC에서 삼바가 접속 안되서 조금 헤매긴했는데(그놈의 guest 계정)

  CEC 해두니 리모컨 산 값을 톡톡히 하는 듯. 재생시 -10초 +10초만 해두니 오히려 더 편하다.

6. 포켓몬고

하루 20만 경험치 빡세네.. 레지락 나와서 잡는데 죄다 별 2개.. OTL

7. 첫 녀석 데리고 산책

포켓몬 잡으러 같이 갔는데 겸사겸사 마트 들러서 머리띠 사주려다 돈이 더나간듯..

이브이 핸드폰 줄 하나 얻었음 된거지 머.. (그걸 가장 좋아함)

1.

방탄유리를 붙였는데 그렇게 주의했거늘

어디선가 들어온 0.5mm 정도의 금속성 가루가 하나 들어가서 마음이 아프다 ㅠㅠ

2.

의외로 조이콘 조립이 쉽지 않게 만들어졌고

비쌀만 하구나 라는 생각이 드는것과 반대로

도대체 저 조이스틱 부품은 왜 저 따구인가를 고민하게 만드는 상황

일단은 FFC대신 FPCB를 많이 사용했고 조립난이도가 중간에서 상급?
