raspberry pi 4用家討論區

噚晚pi 3 a+ 殼同heatsink送到，不過個殼冇透氣窿，密冚熱度會高過冇殼，大概50C, 但靚仔好多



Pi 3 a+ 適合做Audiophile, 由於冇RJ45, 玩volumio setup要咁
https://forum.volumio.org/volumio-rpi-t11825.html

如果做raspbian headless server, 就只係flash完mirco sd咭，喺boot度開番ssh同寫番WiFi嘅config就得

部 pi 3 a+跑呢幾樣嘢, 128GB mirco sd咭, 成個成本

pi 3 a+ 198
mirco sd咭 100MB/s 107
殼 45
heatsink 40 (可有可無, 不過買個日以為pi 4b咁熱買埋,測試之後我話唔使用

電源求其搵個5V2A(最好2.5A)就得, 我用拖版USB嘅叉電位

運行嘅嘢就係proxy, file sharing同bt box, openvpn只用嚟連接nordvpn bt, 冇起server

系統資訊, 運作良好,穩定

有冇人試過攞黎做 moonlight client streaming pc game 打機

Raspberry pi zero 幾時出新版，ram 加一倍都好
512連command line 都疾下疾下

ssh玩掃雷



bash script嚟, 輸入

wget https://raw.githubusercontent.com/feherke/Bash-script/master/minesweeper/minesweeper.sh 下載, 之後 chmod +x minesweeper.sh就得

唔會啩? 我有啲VPS得128MB ram, 由於係OpenVZ虛擬技術, 冇得開swap file, 跑OpenVPN同shadowsocks-libev成十幾個用戶都冇問題

headless server只係跑吓proxy, bt, file sharing, 應該夠用, 開多個512MB swap, 好穩陣

我試過純用command line 裝python 堆嘢都會成部死

咁就唔知了, 好似shadowsocks-libev呢啲socks5 proxy, 好少 ram已經可以處理幾百個連接, 我睇過幾MB ram就做到, 所以佢官網都教點限制

Security Tips
For any public server, to avoid users accessing localhost of your server, please add --acl acl/server_block_local.acl to the command line.

Although shadowsocks-libev can handle thousands of concurrent connections nicely, we still recommend setting up your server's firewall rules to limit connections from each user:

# Up to 32 connections are enough for normal usage
iptables -A INPUT -p tcp --syn --dport ${SHADOWSOCKS_PORT} -m connlimit --connlimit-above 32 -j REJECT --reject-with tcp-reset

之前又試過係3B+ 裝steam link, 不過係揀game 畫面 係咁閃, 唔知係咪要update 曬所有嘢先😅

重用緊Jessie, 幾個server 係入面唔敢亂嚟

o係pi 3a+ 裝o左個 text rss reader - newsbeuter, 算OK, 就係i10n冇正體中文, 得殘體, 可能係冇乜正體中文用家.....

內文正體中文字有一兩粒字出唔到, 唔知係咪terminal問題?

巴打你用咩distro?

raspbian lite

sudo mount -o uid=nobody,gid=nogroup .........................
咁樣得唔得?

RPi 3 用嚟收ads-b

我估要改owner ,
sudo umount /mnt/XXXXX
chown -R pi:pi /mnt/XXXXX

如果係用NFS , /etc/exports 要有類似咁

*(rw,all_squash,insecure,async,no_subtree_check,anonuid=1000,anongid=1000)

pi@headlesspi:~ $ echo $UID
1000
要對應番, 我冇auth, 限制內網device用

另外如果係用raspbian 或者係 raspbian 衍生版本, 用WIFI o既, 要關閉佢個自動熄WIFI慳電功能,如果唔係耐o左冇流量會斷開同router WIFI 連接, 輸入

sudo /sbin/iw wlan0 set power_save off

之後

sudo nano /etc/rc.local

o係 exit 0 之前加番落去, 咁每次boot機就會自動執行

_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

/sbin/iw wlan0 set power_save off #加o係呢o度
exit 0

想玩呢個好耐
想問下ads-b係咪是但買 用佢跟既天線就可以？

係呀 但係基本上 tv dongle 得返淘寶有得買


你如果想收到好啲嘅 要喺淘寶買 1090Mhz天線

咁你之後再加 raspberrypi-ui-mods?
定係其他UI嚟？

唔係 pi4b安裝正常raspbian桌面版本, pi3a+係headless嘅, 靠ssh入去操作, 所以安裝raspbian lite就得

以前用3b+做headless有裝過VNC server嘅, 太lag實際用唔掂, 就算用1024*768 16bit color, 開firefox/chromium都係lag得好緊要, 而家唔會再搞VNC server直到raspi硬件做得唔lag先

自膠，見到個play store logo了
以為你個cap screen最出面係raspbian lite

Chromebook嚟, 有debian terminal

想買個raspberry pi 4玩吓, 去邊度買好?
argon40送貨要等勁耐

rsonline?
