Raspberry Pi 大量組合方案

未分類
這是一篇 Raspberry Pi 大量組合方案的文章



如果你有 Raspberry Pi 大量安裝/組合的需求



可以先看這篇文章 再進行採購 或是佈局



IMG_6258









因為一個 關鍵字排名網站 seo-rank.tw 的關係



我需要很多 Raspberry Pi 來讀取 Google/Yahoo 的排名



我大概前後買了快20台 Pi 吧



(20台好像很多 我聽過有人買上百台的)



當 Pi 一多的時候



你就很難用原本那幾片簡陋壓克力來配置這些機器



當然還有電源供應的問題



正常人一開始買 Pi 回來玩



都會買這種壓克力的外殼



IMG_6258



當數量一多的時候



就會變成這樣



IMG_6259



這還沒有拉網路線跟電源線喔



這是買 Pi 的時候會一起購入的電源線



IMG_6262



USB 電源線可能會比這爛一點



是那種聞起來會很臭的臭塑膠



然後那個豆腐插頭 當你有5台 Pi 的時候



就會有五個 插滿你的延長線插座 非常難控制



後來我去找 USB Hub



通常網路賣場找到的 是那種可以傳輸資料的



供電能力都很弱



不然就是外接電源



但是串了一個變壓器 (但是供電可能還是只有 1A)



我超賭爛變壓器 因為變壓器會卡我的延長線插座



一個 device 就垂一個蛋蛋 看起來就很討厭





(圖片版權為該廠商所有)





後來我找到這種 純粹供應電力的 USB Charger (充電器)



IMG_6260



5 port 的可以搭配五台 Pi (大約七八百台幣)

(也有 6 port的)

重點是他內建變壓器

所以他只有一條線直接連到插頭

也不用垂一棵變壓器



一般都會有兩個 2.1A 的

(本來是設計要給 iPad 一類的平板充電用的)



除了 ORICO 以外 還有 Anker 這個日本品牌可以選



這可以解決電力供應的問題



本來我還去光華商場買了 Power Supplier (就是電工給電的那種)



ND House~LRS-200-15 薄型 明緯MW電源供應器 200W 5V 14A,可替代NES-200-15



14A 可以供應14台 Pi (最多)



不到1000圓



還有20~30A以上的都有



不過拉電路之類的就有點類了



畢竟我是寫程式的



對電工的東西真的不熟



另外 Pi 的電源 其實還可以從 GPIO 下手



GPIO 3號 針腳是 5V+ 的接腳



從這也可以給 Pi 電力供給



不過一樣 需要大量電路經驗才能處理



所以我還是放棄了











至於 Pi 的置放



本來還自己用珍珠板設計



後來用銅柱去鎖

銅柱的特寫



IMG_6256



第一代的 Pi 只有兩個孔可以鎖



Pi B+ 跟 Pi2 改成四個孔



可以鎖四根銅柱



當然鎖兩根也可以 就比較不穩



後來又去淘寶找了這樣的東西



螢幕快照 2015-05-16 下午9.47.53



其實這台灣的拍賣賣場 也有廠商提供這樣的套件



只是非常貴



單層的 (只能裝一台 Pi 的) 竟然就賣 250



對岸的 我買了 四層的 (可裝四台Pi) 也才 250左右



雖然一塊壓克力板賣 50圓 算是暴利



但是相對台灣只有 20% 的價錢



當然就馬上買了兩套來玩玩看



組合起來長這樣



其實和淘寶賣場的照片沒什麼兩樣

(圖片最下方黑色的是 Switch Hub)



其實跟我直接用銅柱鎖也沒兩樣



唯一的差別是



Pi 所提供的孔 是給比較細的螺絲釘鎖的



銅柱的羅拴比較粗



所以要很大力才鎖的上去 (對板子來說是一種破壞)



淘寶賣的套件



是把 Pi 先鎖在壓克力板上



然後再用銅柱去組合壓克力板







問題又來了 這麼多 Pi 要連接網路



如果接 ADSL 的數據機



一般數據機只有 4個 接孔



如果你還有接 pc



勢必得接一個 Switch Hub



然後 Switch Hub 又要插插頭



很賭爛



後來研究一下



一般 Switch Hub 都是 5V 或 12V



比較高級(耗電)的會用 12V



(像中華的 ADSL 數據機就用12V)



去拍賣買了這樣的電子零件



USB 轉 DC (DC 接口有粗細 要看設備是多粗的孔)

然後從 USB Charger 給 Switch Hub 電力



(或是從連接 2.1A 的 Pi 的 USB Port 給電也可以

這樣可以省一個 USB Charge 的 Port)



網路我也有想過用 Wifi



這樣連 Switch Hub 都不用買



不過一個 USB 網卡約 100~150圓



五台 Pi 大概就是 500~750圓



有的人怕輻射 可能就不太適合



而且數量一多 連線品質也不太好



所以看個人喜好





網路上也有各式各樣大量 Pi 的組合方案



樂高組合方案



http://www.techbang.com/posts/10807-64-raspberry-pi-plus-lego-mini-computer-supercomputer-made-of-what



也有40台 Pi 的組合



http://likemagicappears.com/projects/raspberry-pi-cluster/



不過我還是希望能設計自己的 Pi 組合方案



等我有做出什麼新的組合方案再跟大家分享~
