1945年三位一体核试验的失传图像获修复
1945年7月16日，美国在新墨西哥州进行了人类首次核试验“三位一体”试验。近日，一批此前被认为已失传的试验图像被成功修复，为研究这一历史事件提供了珍贵的新视角。这些图像展示了原子弹爆炸的瞬间及其毁灭性力量，填补了历史记录的空白。

A hobbyist salvaged vacuum fluorescent display (VFD) tubes from an old calculator and built a custom clock. The project involved reverse-engineering the tube pinout, designing a multiplexed driver circuit with a MOSFET and microcontroller, and using a 32.768 kHz crystal for accurate timekeeping. The finished clock was mounted in a CNC-milled wooden enclosure.
The article describes building a voltmeter clock where the design focus was as much on the wooden enclosure and aesthetics as on the electronics, highlighting that circuit design can be as much about craftsmanship as engineering.
