【开源】纯手工低成本打造拟辉光管时钟，也可以很酷炫

發(fā)布時間：2023/12/29 编程问答 31 豆豆

生活随笔收集整理的這篇文章主要介紹了【开源】纯手工低成本打造拟辉光管时钟，也可以很酷炫小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

不想錯過我的推送，記得右上角-查看公眾號-設(shè)為星標，摘下星星送給我

《命運石之門》里 “世界線變動率探測儀”，各種輝光管的作品，讓熱愛DIY的小伙伴歡喜，但是輝光管的價格又望而卻步，并且現(xiàn)在已經(jīng)很難買到了。怎么能難倒我們的工程師呢？擬輝光管時鐘制作指南來了，先看一張效果圖：

制作過程如下視頻（英文原聲，大家自行理解）：

在分享制作過程之前，我們先來了解下LIXIE顯示原理。

LIXIE的一端包含有LED，也可以是WS2812B智能LED，能根據(jù)需要改變顯示顏色的。LED發(fā)出的光線被聚集到一疊樹脂玻璃Plexiglas中。這類“端面照光”顯示器利用全內(nèi)反射的現(xiàn)象，可將光保持在樹脂玻璃內(nèi)刻蝕出圖案的區(qū)域。每片代表一個數(shù)字，并且通常一次只照亮一張樹脂玻璃片，從而顯示出具體的數(shù)字。

在今天分享的時鐘項目中，時鐘和分鐘的顯示需要四位數(shù)，每位數(shù)需要雕刻出0-9這些數(shù)字，然后再添加兩個圓點來區(qū)分小時和分鐘，所以總共需要82個LED。這里指示數(shù)字使用藍色LED燈，區(qū)分時分圓點的用白色LED燈。

除了82個LED之外，還需要以下器件：

ATmega328P，即Uno MCU
MCP23017 集成電路
兩個 22pF 電容器
330 歐姆電阻
RTC 模塊組件，DS3231
16 MHz 石英振蕩器
藍牙模塊HC-05
EEPROM，CAT24C02WI-G
蜂鳴器
一些端子連接

所有這些 LED 與 Arduino 的接線，將相同行的陽極焊接在一起以獲得 10 行和相同列的陰極。

之后，使用 Arduino 代碼控制所需的數(shù)字就會非常容易。如果想了解如何控制相同矩陣的 LED ，大家可以去搜下光立方的控制方法。

制作的第一步：CAD 和硬件零件。

從激光雕刻和切割零件開始，使用 solidworks 軟件制作了上述設(shè)計，可以從文末的下載鏈接獲取 DXF 文件，此設(shè)計 100% 推薦用于幫助大家制作設(shè)備。

制作的第二步：電路圖繪制。

整個控制電路圖如下：

使用RTC模塊組件進行校準時間和日期配置等，并且通過I2C與MCU建立通信以進行數(shù)據(jù)傳輸。在時鐘里添加鬧鐘功能，可以通過蜂鳴器進行提示。為了與時鐘接口，使用藍牙模塊，調(diào)用Android 應(yīng)用程序，實時調(diào)整時間和日期。

制作的第三步：PCB焊接。

制作電路圖后，將其轉(zhuǎn)換為定制的PCB設(shè)計，并投板生產(chǎn)。

這就是仿輝光管LIXIE時鐘所有的組件了：

一切準備就緒，下面就開始將電子元件焊接到 PCB 上，為此需要烙鐵和焊芯線以及用于 SMD 元件的SMD rework（如果使用 RTC 模塊，則不需要）。

下圖是已經(jīng)將每個組件焊接到其位置，可以使用PCB的兩面來焊接電子元件。

接下來就是進入硬件焊接的第二部分，LED連接，大工程。

正如上面的照片中看到的，在設(shè)計中為每個 LED 創(chuàng)建了一個孔，因此只需使用一些膠水固定 LED，然后將相同行的所有陽極和相同列的陰極焊接在一起。完成之后，將有 14 根用于矩陣的電線，因此只需擰緊它們。

然后，將放置Plexiglas零件并擰緊連接點來繼續(xù)組裝。

制作的第四步：軟件部分。

現(xiàn)在需要的只有軟件代碼，這個Arduino代碼可以從文末的鏈接免費獲得。代碼做了注釋，大家可以根據(jù)自己的需要進行調(diào)整。

代碼編譯完成之后，就可以使用 Arduino IDE將代碼上傳到 ATmega328 MCU，然后將MCU 放置在 PCB 上的插座中即可。

最后，使用外部 5v 電源適配器給整個項目供電，就可以測試了。

當(dāng)然，還可以創(chuàng)建了一個Android應(yīng)用程序來使用它，同時設(shè)置時間，日期和時鐘的鬧鐘。

雖然這個項目制作過程很簡單，但整體來說是一個比較有趣，有實際意義的作品。這個作為一個引子，大家可以DIY自己的時鐘，比如使用不同顏色的LED來顯示數(shù)字。

好了，接下來的時間，交給大家了，高清原理圖，源碼，CAD文件，都在下面鏈接了。
