People in hotter parts of the world may permit themselves a grin at this, but Europeans have recently been suffering under an unseasonal June heatwave. Most of us have been cowering inside with our air conditioners, but not [Making Stuff With Mike]. He’s adapting a safety helmet with a Noctua fan for only slightly uncool on-the-go cooling.

On the face of it, the hat is a straightforward hack. [Mike] mounted a 3D-printed chimney to the top of a hard hat and placed a fan in the top of it. But as always, there’s a little more to it than meets the eye, and in this case it’s because he’s modeled the hat/chimney interface by 3D scanning the hat and using the scan to create his CAD model. The two are attached with four small bolts, and a set of large holes are made in the hat for airflow. Taking it out for a spin, he finds it does the job, but has a few ideas for improvements.

So Mike’s ready for the upcoming BornHack hacker camp, which Hackaday has been to a few times. We’re not so lucky with headgear, but at least if there’s a heatwave, they have plenty of hammocks in the trees.

世界上更热地区的人们可能会对此一笑置之，但欧洲人最近却遭遇了不合时宜的六月热浪。我们大多数人都在室内开着空调瑟瑟发抖，但[Making Stuff With Mike]可不是这样。他正在改装一顶安全帽，装上Noctua风扇，实现一种不算太酷的移动降温方案。

从表面上看，这顶帽子是一个直接了当的改装。[Mike]将3D打印的烟囱安装在安全帽顶部，并在其中放置了一个风扇。但一如既往，它并不像看上去那么简单，这一次是因为他通过3D扫描帽子并利用扫描结果创建CAD模型来设计帽子与烟囱的接口。两者用四个小螺栓固定，并在帽子上开了一组大孔用于气流。他试戴并测试后发现效果不错，但还有一些改进的想法。

所以Mike已经为即将到来的BornHack极客露营做好了准备，Hackaday已经去过好几次了。我们在头饰方面就没那么幸运了，但至少如果出现热浪，树林里还有很多吊床。
