[lcamtuf] is not just a calculator superfan, but also a skilled builder. That much is evident in the fabulous  design of Calcumator 2000, an electromechanical calculator that uses voltmeter readouts as digits (plus one at the bottom to represent decimal place). There are plenty of high-quality build images, so give it a look!

Calcumator 2000 is a bit of a love letter to a time when display technology hadn’t quite yet produced anything suitable for calculator use. This resulted in calculator designs that are generally unrecognizable compared to the 7-segment display based devices we see today. The Calcumator 2000, in all its electromechanical glory, would have fit right in that era.

The Calcumator 2000 has all the usual buttons one would expect from a simple calculator and drives a total of seven readouts, one of which acts as the decimal point. The idea of using voltmeters as digit displays came from [lcamtuf]’s voltmeter clock, an earlier work with a similar attention to detail in its design and assembly.

We want to take a moment to admire how clean the blue panel is. [lcamtuf] made it by painting one side of an acrylic panel, cutting the letters and design out on a CNC mill, then filling with white paint. The depth of the cuts gives the white elements a nifty multi-layer effect that really complements the design.

[lcamtuf] 不仅仅是计算器的超级粉丝，还是一位技艺高超的建造者。这一点在其精美的设计——Calcumator 2000 中体现得淋漓尽致。这是一款机电式计算器，它利用电压表的读数来显示数字（底部还有一块用于表示小数位）。附有大量高质量的构建图片，快去看看吧！

Calcumator 2000 可以说是对那个时代的一封情书——那时显示技术尚未生产出适合计算器使用的任何东西。这导致了与我们今天看到的基于7段显示器的设备相比，当时的计算器设计通常难以辨认。Calcumator 2000，以其全部的机电辉煌，完全适合那个时代。

Calcumator 2000 配备了简单计算器应有的所有常用按钮，并驱动总共七个读数器，其中一个作为小数点。使用电压表作为数字显示的想法源自 [lcamtuf] 的电压表时钟，这是他在设计和组装上同样注重细节的早期作品。

我们想花点时间来欣赏蓝色面板的整洁度。[lcamtuf] 通过在一侧涂漆亚克力面板，用CNC铣床切割出字母和设计，然后用白色填充。切口的深度给白色元素带来了巧妙的多层效果，完美地衬托了设计。

想看看它的工作原理吗？是的，你一定想。看看下面嵌入的视频吧。
