언더싱크 정수기 설치

산본은 구 신도시라서 아파트가 모두 지은지 20년은 넘어서 배관에서 녹물이 나옵니다.

보시는 것 처럼 간단한 필터를 설치 해 보았지만 금방 누렇게 변해서 도져히 그냥은 못 살겠더라구요.

그래서 정수기를 이마트에서 정수기를 알아 봤는데 렌탈? 개념에 필더를 교환해 주는 방식은 제일 싼게 60만원 이상이더 군요.

그나마 싼게 정수기 설치 해주고 자가 필터 교환 방식이 20만원 정도 더 군요.

인터넷에 찾아 보니 자기 설치, 자가 필터 교환 방식의 정수기가 아주 저렴한 가격이 더군요. 필터 포함 약 4만원 정도 입니다. 그래서 주문...

처음에는 저기에 연결하려고 시도...

그냥 사이 배관 연결 부위에 연결...

설명서에 나와 있는 것 처럼 필터를 연결 하고 보니 위에 있는 구멍이 뚜껑에 맞는 구멍이랑 사진처럼 밑으로 호수를 연결해야 합니다. 참고 하세요.

배관을 이미 잘라서 전 본체를 상하 뒤집어 설치

전동 드릴로 구멍을 냈습니다.

4만원에 자가 언더 싱크 정수기 설치 끝~~

Automatically match the density for ODROID-VU7.

Edit boot.ini for ODROID-VU7.

setenv hdmimode "800x480p60hz"

# HDMI/DVI Mode Configuration
# This will enforce the signal type of display
# "hdmi" - For HDMI interface
# "dvi" - For DVI interface
setenv vout_mode "dvi"

If you use the low resolution screen like the ODROID-VU7, you need to edit the lcd_density value manually to show the navigation bar properly.

Change “ro.sf.lcd_density=160” to “ro.sf.lcd_density=120” in build.prop file.

$ su 

# mount -o rw,remount / 

# vi /system/build.prop 

# reboot 

We will automatically match the density without modification.

Make set_density.sh

---------------------------------------------------------------------------
sleep 5
SIZE="Error type 2"

while true
do
case $SIZE in
Error*)
echo "wm not ready"
sleep 1
SIZE=`wm size`
if [ "$SIZE" == "" ]; then
SIZE="Error type 2"
fi
;;
Physical*)
if [ "$SIZE" == "Physical size: 800x480" ]; then
wm density 120
break
else
wm density 160
break
fi
;;
esac
done
---------------------------------------------------------------------------

$ adb remount
$ adb push set_density.sh /system/bin/

Edit /init.odroidc2.board.rc

---------------------------------------------------------------------------
service auto_density /system/bin/set_density.sh
    class main

How to expand userdata partition on ODROID-XU3/4 by Gparted.

I want to expand userdata partition to install app more.

Check current partition information.

system partition   | /dev/sdx2 | 1GByte

userdata partition | /dev/sdx3 | 2GByte

cache partition     | /dev/sdx4 | 256Byte

fat partition          | /dev/sdx1 | All the rest

Remove cache and fat32 partition. If you modified boot.ini backup first.

Select userdata partition and resize. I will resize twice.

userdata parition : 4GByte.

Create new partition for fat like picture.
assign 256 for cache on 'Free space preceding (MiB):'

Create new partition for cache like picture.

Complete.

This also applies to ODROID-C1.
