Slurptop 目录：设计过程 | 电力输送 | 物料清单 | 结语。基本构建规格：Ryzen 7 7730u 笔记本 CPU（8 核/16 线程）、64GB DDR4 内存、500GB NVME 固态硬盘、14 英寸 16:10 屏幕（1920x1200）、定制 82 键机械键盘、集成轨迹球鼠标、使用 Kobalt 电动工具电池的 UPS 供电系统（可更换，遗憾的是不支持热插拔）。

A Genesis of an Idea Prior to completing this project I didn’t have a modern laptop. I also had never tried out a trackball mouse. After completing a Writerdeck and a Cyberdeck based on Raspberry Pi SBCs, I felt that it would be incredibly useful to have a full-fledged x86 portable computer. You know, a laptop. Why not spend two months designing, building, and refining a laptop myself instead of just hitting up Best Buy for a new laptop that’s ready to go? I mean, I don’t have good justification beyond “because I can, and I want to”, but sometimes that’s all the justification you need!

创意的起源：在完成这个项目之前，我没有现代笔记本电脑，也从未使用过轨迹球鼠标。在完成了基于树莓派单板计算机的 Writerdeck 和 Cyberdeck 后，我觉得拥有一台成熟的 x86 便携式计算机——也就是笔记本电脑——会非常有用。与其去百思买（Best Buy）买一台现成的笔记本，为什么不花两个月时间自己设计、制造并打磨一台呢？除了“因为我能做到，而且我想做”之外，我没有更好的理由，但有时候这就是你所需要的全部理由！

The Design Process Begins At the outset of the design process I started looking at Intel N50 and N100 mITX motherboards and PicoPSU power delivery, but started getting discouraged at the price prospect of something that was more expensive than a Raspberry Pi, consumed more power, didn’t offer much more computing power than a Pi, and consumed significantly more power. That’s when I figured if I was heading in a high power draw x86 setup, why not start shopping out some mini PCs? That’s where I found some decently spec’d out units with laptop processors and integrated graphics. These, I figured, would fit the bill for a machine that would be destined for some coding and light design work.

设计过程的开始：在设计之初，我开始研究 Intel N50 和 N100 mITX 主板以及 PicoPSU 电源，但考虑到其价格比树莓派贵、功耗更高，且计算能力并没有比树莓派强多少，我开始感到气馁。于是我想，如果我要搞一套高功耗的 x86 系统，为什么不直接去选购一些迷你 PC 呢？我找到了一些配置不错的设备，它们配备了笔记本处理器和集成显卡。我觉得这些设备足以胜任编程和轻量级设计工作。

Next up would be figuring out the power delivery. Since my last folding screen Cyberdeck, I’ve been really enjoying designing within the Cyberpunk aesthetic. One of the aesthetic aspects that I felt the last build was missing was improvised part selection. Then I had the thought of powering the unit with a 24v power tool battery. The design aesthetic and the improvised hardware selection dovetailed beautifully in the design of the power delivery. The mini PC I bought had a 19v/5a power supply, and my power tool batteries were 24v. With a properly spec’d boost/buck converter, that should work perfectly both on the aesthetic requirement as well as the power and current requirement.

接下来是解决电力输送问题。自从上次制作折叠屏 Cyberdeck 以来，我一直很喜欢在赛博朋克美学框架下进行设计。我觉得上次构建中缺失的一个美学要素是“即兴零件选择”。于是我想到用 24V 电动工具电池为设备供电。这种设计美学与即兴硬件选择在电力输送设计中完美契合。我买的迷你 PC 配备的是 19V/5A 电源，而我的电动工具电池是 24V 的。通过一个规格合适的升降压转换器，这在美学要求以及功率和电流需求上都能完美运作。

The Fun Stuff Now we get to the fun stuff: sketching out the design. If you’re interested in Cyberdecks, I’m sure you’ve seen a plethora of devices. From slabs without a hinging screen, to vintage computer style raising screens (like I used on my gray Cyberdeck), to absolutely awesome sliding designs like u/Personalitysphere’s sliding modular Cyberdeck. I wanted something that would have the rough form factor of a laptop. With the form factor decided on, the next step in every project I do is to gather up all the components, grab my calipers, and get to measuring and modeling in Blender.

有趣的部分：现在进入有趣的部分：草拟设计。如果你对 Cyberdeck 感兴趣，我相信你已经见过各种各样的设备了。从没有铰链屏幕的平板式，到复古电脑风格的升降屏（就像我在灰色 Cyberdeck 上用的那样），再到像 u/Personalitysphere 的滑动模块化 Cyberdeck 那样极其酷炫的滑动设计。我想要一种大致具有笔记本电脑外形的设备。确定了外形后，我每个项目的下一步都是收集所有组件，拿起卡尺，开始在 Blender 中进行测量和建模。

I make “good enough” 3d models of EVERYTHING. It’s tedious and time consuming, but I wouldn’t do it any other way. You can package everything so much nicer when using this method, and you run into WAY fewer problems during the assembly stage, WAY fewer redesigns and reprints, etc. This is the “measure twice” process when building a device like this, even though it’s more along the lines of “measuer ten thousand times”. Very worth it, and I highly recommend approaching things from this direction. Not to mention you’re honing your ability to measure and model things, which is invaluable as a desinger.

我会为所有东西制作“足够好”的 3D 模型。这很繁琐且耗时，但我不会用其他方式来做。使用这种方法，你可以把所有东西封装得更好，在组装阶段遇到的问题会少得多，重新设计和重新打印的情况也会大大减少。这就像是制造此类设备时的“量两次”过程，尽管更像是“量一万次”。这非常值得，我强烈建议从这个方向入手。更不用说你还能磨练自己的测量和建模能力，这对于设计师来说是无价的。

After establishing the layout of the individual components, I start going through a process of sketching out designs and layouts. Usually I have a pretty clear vision of what I’m going for at this point, but a lot of design elements are “discovered” at this stage. It’s also where some hard choices have to be made because establishing certain design elements sets you down a road where if you choose to go a different direction you can’t just CTRL+Z you’re way out of. You have to delete a LOT of work sometimes. I’ll jot out some of the notable design choices and processes that I went through:

在确定了各个组件的布局后，我开始草拟设计和布局。通常此时我已经有了清晰的愿景，但许多设计元素是在这个阶段“发现”的。这也是必须做出艰难抉择的时候，因为确定某些设计元素会让你走上一条不归路，如果你想换个方向，无法简单地通过 CTRL+Z 撤销。有时你必须删除大量工作。我将记录下我经历的一些值得注意的设计选择和过程：

I knew because of the size of the finished unit that I wanted to be able to incorporate some aluminum bar material to increase total unit rigidity and strength. I had initially planned on incorporating much more aluminum in the design, but whiddled that amount down in the design process to one bar that spans the width of the laptop, underneath the monitor hinges. It’s designed to be a 4 layer sandwich where the bolts that hold the hinges in place also hold: the rear lower case fan covers, the aluminum bar, and the front keyboard switch plate. These are all bolted down to standoffs designed into the lower case housing that have heatset inserts installed.

由于成品设备的尺寸，我知道我需要加入一些铝条材料来增加整体的刚性和强度。我最初计划在设计中加入更多的铝材，但在设计过程中将其缩减为一根横跨笔记本宽度、位于显示器铰链下方的铝条。它被设计成一个四层夹层结构，固定铰链的螺栓同时也固定了：后下壳风扇盖、铝条和前键盘开关板。这些部件都通过螺栓固定在下壳外壳设计的支柱上，支柱内安装了热熔嵌件。

I didn’t want the screen bezels and overall screen housing to be TOO big and bulky. This was fortuitous because as designed, the screen components and outer lower case frame are EXACTLY sized to my printer bed (340mm) with less than 2mm to spare on either side. The main design principles I had in mind were: Utilitarian (think power tools and modern rugged designs for products meant to be used and abused), Sci-Fi/Cyberdeck almost touching into NASA-punk (this is where a lot of the 45deg facets and bevels come from), and Cyberpunk (improvised design, scavenged hardware, etc).

我不希望屏幕边框和整体屏幕外壳太大、太笨重。这很幸运，因为按照设计，屏幕组件和外下壳框架的尺寸正好符合我的打印机底座（340mm），两侧剩余空间不到 2mm。我心中的主要设计原则是：实用主义（参考电动工具和旨在经受磨损的现代坚固产品设计）、科幻/Cyberdeck（接近 NASA 朋克风格，这就是许多 45 度切面和斜角的来源），以及赛博朋克（即兴设计、回收硬件等）。

The handle was an integral element I wanted from the start, and the final design was ultra satisfying. It sits between the main case base and outer frame so intricately that once the case is bolted together it’s firmly locked in place, even without the mounting bolts for the handle itself. One of those small acheivements that’s hard to describe, but you know what I’m talking about if you’ve ever felt it! I really wanted a 4:3 display ratio. However, I also wanted a usable size screen in the 13-15” range, and didn’t want to spend north of $100 on only the screen, so this 16:10 unit was the closest I could find.

手柄是我从一开始就想要的必要元素，最终的设计令人极其满意。它巧妙地嵌入在主壳底座和外框架之间，一旦外壳通过螺栓固定，即使没有手柄本身的安装螺栓，它也能被牢牢锁定。这是一种难以描述的小成就，但如果你曾经有过这种感觉，你就会明白我在说什么！我真的很想要 4:3 的显示比例。然而，我也想要一个 13-15 英寸范围内的可用尺寸屏幕，且不想在屏幕上花费超过 100 美元，所以这个 16:10 的单元是我能找到的最接近的选择。
