Power over fiber

Hacker News 上看到「Power over fiber (chaos.social)」這篇,是個透過雷射光傳遞能量再轉回電能的方式。

隨意先拉了其中一個 sku 來看,「3 VDC application; ST Port」的 AFBR-POC404L 單顆要 US$561.79:「AFBR-POC404L」,這顆輸入 1.8W 輸出 0.6W。

另外在「Optical Power Converters」這邊可以看到 AFBR-POC306A1 這顆,輸出可以到 3W,查到的單價則是 US$701.77 (AFBR-POC306A1),這個功率已經連 Raspberry Pi 都可以上了...

不過從官方列出的應用來看,可以看到著重在電磁隔離的性質:

  • Fully galvanically isolated power supply without capacitive coupling, suitable for gate drivers
  • Isolation transformer for MRI/RF imaging without the need for filters
  • Optically isolated probes for power electronics with a wider dynamic range than any conventional probe
  • Power source for tethered drones, enabling a higher payload and eliminating the need for battery charging
  • Sensors where power must be immune to EMI, high voltage, and magnetic fields

跟我一開始想的方向不太一樣...

無風扇系統的 CPU 散熱片

最近剛好弄家裡跳板機的硬體,蝦皮上弄了一顆 Intel i3-8100T 回來用,這顆標 35W 的 CPU 基本上還是需要個風扇會比較保險,不像先前在弄 Intel J1900 只有 10W,原廠在上面就放一顆散熱片就搞定了。 剛好手上有一顆 LGA 115x 的風扇可以用,裝上去後平常就在 35 度,跑個程式讓系統滿載大約 55 度,而且這還是沒有系統風扇的情況下,看起來是夠用了。 不過因為好奇,還是找了一下無風扇的方案,結果就看到這顆:「ARCTIC Alpine 12 Passive - Silent Intel CPU Cooler for Intel Sockets 115x and 1200, up to 47 W, Pre-Applied MX-2 Thermal Paste, 95 x 96 mm - Black」。 這顆在…

Twitter 上看到 Intel Atom C3950 這顆 CPU...

Twitter 上看到「Intel Atom C3950 + Tyan Tempest S3227」這篇文章,裡面提到了「Intel Atom® Processor C3950 (16M Cache, up to 2.20 GHz) Product Specifications」這顆 CPU... 建議售價 USD$389,然後 16 Cores (沒有 HT,所以是 16 Threads) 只吃 24W,可以吃到 256GB RAM,不過 Max CPU Configuration 是 1,先記起來好了...

USB 充電器的充電速度

前陣子因為好玩買了 ZY1280P,主要是可以看充電時使用的 Protocol: 其中 D+ 與 D- 資訊可以拿來判斷現在在跑的 Protocol,網路上有不少資料可以看,就會發現各家廠商在早期出了超多的快充協定。 拿到後把家裡各種可以輸出 USB 電源的東西都測了一輪,才發現有超多東西跟預想的不一樣。 首先是 HA2-50U5Q 這顆 USB 充電器: 最左邊兩個 Port 接上去只顯示了 DCP 5V1.5A + SAMSUNG 2A,接 iPad mini 上去也的確只有 1A 左右的電流。而再往右的兩個 Port 接上去就會顯示 DCP 5V1.5A + APPLE 2.4A,這時候 iPad mini 可以吃到接近 12W 左右,另外 QC 2.0 的 Port 也能提供 APPLE 2.4A。 我之前把…
