解決屏幕太暗、對焦困難的問題

本著珍惜、善用現在身邊所有, 不要隨便放棄的觀念, 去鴨寮街跑了一趟, 買了一個 x3 的放大鏡.

DIY 了以下連接的延續篇.

想辦法把它裝在小 DC 上.

去五金店買了一條銅焊枝 (HK$12), 原因是銅焊枝較硬一點, 不會太軟.

根據放大鏡和DC的大小, 做了一個架子 :

在架子上銼了四道固定凹坑位 :

對好放大鏡位置後, 鑽四個孔, 再用紮帶把兩者紮緊 :

裝好了, 這個就是 DIY 遮光放大裝置, 很容易裝上和拆卸 :

看來可以, 但未經現場考驗, 在這個星期天可以試試效果如何了 :

相信好多人的工作比較死板, 在工餘 DIY, 可以用腦思考不怎樣複雜的問題(不會太傷腦筋, 太傷腦筋的問題不太適合 DIY), 同時也可以動腳筋周處找那裡有合適的材料, 跟著回來動動手, 即使中途遇到問題時壓力也不大, 應該對身心腦筋的健康有幫助, 起碼可以減少患上老人癡呆症吧.

因為比較容量找到的材料, 在大多數的五金店都可以買到.

洞與邊緣的距離大於 1英分半, 加上透明底座是 acrylic 造成, 不是普通的塑膠, 而且厚度超過 1英分半, 強度絕對沒有問題的.

關於放大鏡的固定方式, 小弟的想法是如下圖這樣
優點有幾個
1.加工更方便, 連挫刀都用不到, 也沒要鑽孔的地方
2.沒有掛勾遮到 DC 頂部的按鈕或開關
3.最重要的是穩固, 此種連接方式就算扛著器材跑, 放大鏡也不會掉下來
