Using Raspberry Pi to Control a PWM Fan and Monitor its Speed
A lot of people uses fan to cool down their Raspberry Pi 4, but the fan’s noise is quiet problem (in a quiet room). In most case pi didn’t need that amount of cooling performance, so we can use PWM (Pulse Width Modulation) to control fan speed and reduce the noise.
A Better Server Status Monitoring Tool - Glances (htop/top Alternative)
Recently, I’m looking for a temperture and cpu status monitor for my Pi nas server. vcgencmd command and htop get the jobs done, but it’s always better to have them in the same window (htop can’t show temperture which bothers me alot). So I found an cross-platform, python-based htop alternative - Glances, it’s easy to install and super handy. The only downside is that it uses a bit more cpu resources than I expected (on Pi4 4GB version).
安裝 Aria2 在 RaspberryPi 上搭建低耗下載機
Use Raspberry Pi to build a FAKE TimeCapsule (and NAS) - Hardware
There are plenty of Mac mini case modification projects on the internet. Though the unibody aluminum housing design had been there for almost a decade, it’s still the best looking mini computer case on the market imo.
In mid 2019, Raspberry Pi receive a huge update - the Pi 4. We finally got true gigabit ethernet, USB3.0 support, and a lot more. This makes Pi 4 suitable for simple NAS project (also for TimeMachine backup). So I decide to build a fake(?) TimeCapsule with Pi (at least the case is real, or should I just call it “Fake Mac mini” ? lol)
替 Raspberry Pi 添加開關、外接電源燈、狀態燈，以及風扇控制

用 Headless 方式玩樹莓派的朋友肯定都遇過一個問題，就是每次關機都要登入 ssh 才能正常關機，懶一點的直接拔電源，就算沒問題也很麻煩（ 懶到過去延長線切電源都不肯 （欸），所以不如加個開關吧，不僅省時省力還能用正常的 shutdown 程序關機，一石二鳥豈不美哉 (:3[__]4
理解 Raspberry 4 Type C 設計問題
Sorry, this post in currently in Chinese only :(
今年(2019)樹莓派基金會發表了久違的硬體更新，升級到了4代，相信有在關注的朋友們都知道，本次供電設計終於換成了 Type-C (終於有種進化成現代化單片機的感覺)
不過也因為電源電路設計的一些問題導致了有 E-Mark 晶片的 USB-C 線材無法為樹莓派供電（例如 Apple 的 Macbook USB-C 充電線、Google Pixel 3 附帶的 USB-C 線材等），反倒是便宜的一般線材能夠正常運作XD
利用 Raspberry Pi 搭建 NAS
Sorry, this post in currently in Chinese only :(
就只是個基於 Samba 的簡易 NAS 架設過程，沒有任何動靜。
BTW 目前還是使用 Pi3B ，升級後會在補上 Pi4B 速度的差異心得。未來打算再裝上 Aria2 讓 Pi 具有下載機的功能。
利用 Raspberry Pi 搭建 TimeCapsule（仮）- 軟體篇
Sorry, this post in currently in Chinese only :(
相信 MacOS 的使用者應該都熟悉官方提供的備份軟體「TimeMachine」，不過如果是 Macbook 等筆電就比較麻煩了，三不五時就要接上隨身硬碟來備份對於我這種懶人來說，定時備份根本是不可能的任務。
不過備份依然是相當重要的，除了升級系統有機會用到，再來就是現在的 Macbook 硬體如此不可靠你敢不備份嗎(笑)。為了解決懶的問題，我想用無線的方式進行備份。停產的 Airport ，或是群輝（Synology）的 NAS 都有提供 TimeMachine 無線備份的功能，然而這兩者的價格都還是偏高的QwQ
所以在一輪 Google 後，我的解決方法就是利用此篇的主角：樹莓派（Raspberry Pi）來完成這項任務，在 Pi 4 推出後，硬體規格升級到了USB3.0、Gigabit Ethrnet，做個人用的簡易 NAS 已經算是堪用，更不用說對速度要求不高的 TimeMachine 了！
