修复波托贝洛警察局时钟
Fixing the Portobello Police Station Clock

2026年4月11日,笔者应邀协助名为“Action Porty”的社区团体,该团体近期购入了极具历史意义的前波托贝洛警察局。他们此前一直无法调整该建筑十九世纪的钟楼,因此寻求帮助。 尽管有恐高症,笔者仍鼓起勇气攀爬陡峭的梯子,穿过昏暗且布满蜘蛛网的阁楼,最终抵达时钟机械装置处。映入眼帘的是令人惊叹的1877年原始内部机械结构,这些装置在历经多年后,已升级为电动机和报时控制系统。 这座建筑最初曾是市政厅,后来先后被用作图书馆和警察局,目前正处于社区主导的修复工程中。当笔者在钟楼内探索时,楼下的志愿者们正忙于拆除20世纪70年代的装饰,以还原建筑最初的维多利亚时代风貌。这是一个充满冒险的周六,也是为保护当地重要历史遗产所做的一次贡献。

本次讨论围绕一篇博文展开,该文详细介绍了修复和维护苏格兰波托贝洛一处前警察局古董钟的过程。这一社区主导的行动在 Hacker News 用户中引发了热烈的技术讨论,主要涵盖以下几个主题: * **钟表机械与改装:** 用户分析了该钟表的现状,指出其目前使用的是电动机而非传统的重锤,并探讨了其中那块定制的手工电路板的奥秘;一些用户推测该电路板可能是老式的教堂钟声控制器。 * **工程与监控:** 参与者建议采用现代、低成本的方式监控钟表运行状况,例如安装 PoE 网络摄像机或振动传感器,以检测齿轮是否卡滞。 * **机场安检轶事:** 讨论中出现了关于机场离子迁移谱分析仪的岔题,用户分享了因甘油(存在于电子烟或婴儿湿巾中)或炸药残留导致的误报经历,从而引发了关于“安检表演”本质的广泛探讨。 * **社区参与:** 该帖激发了读者关于本地志愿服务以及协作式实践社区项目价值的讨论。

I got a message from a friend today which read along the lines of "I know we were going to meet in Edinburgh today, but do you fancy meeting in Portobello instead and trying to fix the clock in the old police station with me?"

I don't know about you, but clambering around the dusty nineteenth century clock tower of an abandoned police station sounds an ideal way to spend a Saturday afternoon to me, so I jumped at the chance.

The rather grand Portobello Police Station building.

This was in response to a message from Action Porty:

"Can you help keep Portobello on time? Action Porty has recently bought the Police Station for the community, but we can't work out how to change the time on the clock tower! We wondered if there was anyone in the community with expertise that could advise us of the details for changing the time? Or who best to contact for help?"

The bit I hadn't figured out was that clocks are high up. If we were to fix the clock we would be next to it and so we would also be high up. And being high up involves heights, and steep long ladders are needed to get up high.

I suppressed my whimpers at climbing up the rather high, steep ladder into the likely spider-infested darkness and was rewarded with an explore of the attic, which lead to another set of steps which went to the clock tower itself.

Once there we were rewarded with the magnificent sight of the clock mechanism and its three clock faces:

Construction of the building apparently started in 1877 and it seems quite feasible that this was an original mechanism. Modifications had been made - electric motors powered the mechanism and a control box allowed the clock chime to be turned off overnight.

The building was built to house meeting, administration and courts for Portobello burgh council. After Portobello was absorbed into Edinburgh the building became a library, and then a police station.

The Scottish Land Fund has since enabled it to be purchased for community ownership and when I went there many volunteeers were removing the 1970s polystyrene ceiling tiles and wood-chip wallpaper to reveal the original grandeur of the building.
