离网赛博终端：树莓派应急求生套件
Off-Grid Cyberdeck: Raspberry Pi Recovery Kit
2019 — 2022，它一次次回到首页
黑点是上首页（≥ 50 分）的那次投稿，空心点是没冲上去的投稿，点越大分数越高。
导读
这是一个基于树莓派的离网/应急 cyberdeck 项目，把定制外壳、电池、网络设备和离线计算打包成可携带的恢复工具包。页面详细记录了硬件选型、组装过程和实战考量，适合想在断网断电场景下自建通信与计算设备的人。
为什么经久不衰：它把应急通信、离线资料和 DIY 硬件整合成可复制的方案，并持续引发关于“离网设备到底实不实用”的讨论，所以多年后仍值得读。

离线软件包自给是这类项目最关键的缺失环节。
最近玩树莓派和 BeagleBone 让我很抓狂：我做的每件事都要从互联网 apt-get，基础镜像连 screen/tmux 都没有。如果软件仓库因故不可访问，一堆硬件就很难派上用场。我知道有 apt-cache 和 squid 缓存，但我真正需要的是把用过的每个 apt-get 和 GitHub 前 5 万个包都塞进 SD 卡，并告诉我怎么用的工具。作者提到这是未来方向，但我认为这是最重要的方向之一。

As I've been playing with Raspi's and Beaglebones and stuff lately, it's been driving me nuts that EVERYTHING I do needs to be apt-gotten off the internet, the base image doesn't even include basics like screen/tmux. If those repos are inaccessable for any reason, I have a bunch of hardware that's very hard to do anything useful with. I know there are such things as apt-caches and squid caches and stuff, but I could really use thing that goes through every apt-get I've ever done and the top 50,000 packages on github and stuffs 'em all onto an SD card and shows me how to use them from my commandline. OP mentions this as a future direction for the project, but I think it's one of the most important.
网络交换机的功耗会迅速耗尽便携电池。
我很喜欢这个项目！但作为把有线和无线网络及充电站整合进工作背包的人，我可以打包票：那个 Netgear 交换机开起来会像子弹一样耗光你的电池，你需要更大的电池。

I really like this project! But I speak from authority, having fully integrated a wireless and wired network and charging station into a carry bag for work uses: Thar Netgear switch will cut through your onboard battery like a bullet. You'll absolutely need a larger battery if you flip that switch on.
批评项目重外观轻实用，电源、耐用性和接口选择在应急场景下都有问题。
外观很酷，但更像 cosplay，而不是灾难中真正有用的东西：离网时电从哪来；没有电网和互联网，你大概率有更大的问题；树莓派不算耐用，SD 卡更是最脆弱环节；锡纸衬里的纸板盒挡不住 EMP；军规连接器很酷但不通用，母头至少还能在应急时插线。

That's neat looking, but it really strikes me as a kind of cosplay than anything that would actually be useful in any kind of disaster situation: 1. If you're off the grid, where are you going to get power to run this? 2. If there's no power grid or internet, you probably have much bigger problems than "how can I browse an offline copy of Wikipedia." Those problems would probably last longer than you want to schlep around and item like this. 3. I'm not under the impression that Raspberry Pi's are especially durable, though the SD-card storage is probably the weakest link (though both those things probably have benefits of being common things that allow for the scavenging of replacement parts). 4. If you need to protect from an EMP, I don't think "tinfoil lined cardboard box" will be sufficient. I was reading up on that a couple of months ago when the war started, and it sounds like little gaps in the shielding can seriously compromise the effectiveness of the sheilding. 5. Mil-spec connectors look cool, but if you need to use something like this, you'll probably want connectors that are a common as possible. A connector is useless if you don't have anything to plug into it. Some kind of terminal block would probably make more sense. Using a male connector seems like a particularly fatal flaw (if you used female, you'd at least be able to stick wires in the holes in a pinch). If you want to usefully prepare for any doomsday scenario, you probably need to really carefully think about your actual requirements in that scenario, and then build to those requirements. IMHO, if it's an actual doomsday, it's probably safe to assume technological society will collapse and not recover for generations, and any high technology would in reality be a short-to-medium term consumable that will break without replacement.
软件和离线内容（如 Kiwix）才是离网设备的主要挑战。
我折腾离网 cyberdeck 有一阵子了，硬件方面这个项目是不错的发现。我最近的主要难题是软件侧，主要是 Kiwix 这类离线内容方案。

I have been tinkering with a cyberdeck for a while now for off-grid usage, so this is a nice find for the hardware side. My main battle lately has been building out the software side; primarily Kiwix (https://www.kiwix.org).
