这是一只会撒娇求安抚的绯红狐狸。用萌动得让你难以忽视的姿势撩你，提醒你给它安抚。在它的央求下，你暂时放下手上的枯燥工作，和它来个互动、小憩一下，你原本机械的工作状态也平添了几分乐趣和安慰……（有创造力的朋友当然可以发挥一下，直接做个小姐姐也没有什么不可以。）
咳……进入正题。这只可爱的小狐狸会像动物一样呼吸。当你开始工作时，轻轻地抚摸它，表示你开始工作了。当你工作许久后，小狐狸就会躁动起来，呼吸好像会变得沉重。发生这种情况，你得再次抚摸它，可以让它恢复平静。你也会马上意识到自己也需要休息调剂一下，喝个茶、吃点东西亦或是起身做个瑜伽。
经过短暂休憩，你可以再次轻轻地抚摸狐狸，告诉它你将继续工作。当你再次忽略它的时候，它会再次来讨你的宠爱，十分乖巧！
材料清单
Arduino pro micro ×1micro USB转USB电缆×1步进电机×1电机驱动器×1小面包板×2彩色LED灯带×2电线×若干10M电阻×1100M电阻×29伏电池×19伏电极夹×1人造革×1胶合板×1纸板×1铝箔纸×1胶水×1针和线×若干
操作预警：使用的人造革确保它不含任何PVC成分。人造皮将经过激光切割，如果含有PVC，切割时会释放氯化物的有毒气体。如你不能确定所用皮革是否含有PVC，可用剪刀来切割线条。
切割原材料
根据模板用激光切割机切割所有材料。如图所示，所有红线都需要切割，所有黑线需要雕刻。根据自己的要求设置好激光切割机。我建议，可先用一张人造革测试一下，以测定雕刻部件的深度是否足够。如果没有激光切割机，也可以在纸上打印模板并手动切割所有模板，只是会花费更长的时间。切割文件可在本项目文件库中下载。http://make.quwj.com/project/81
将皮革粘贴到纸板上
纸板用作皮革的支撑材料，方便弯曲。除六边形外，皮革的每个表面都有匹配的纸板。根据皮革的形状将它们粘在皮革上。边缘处的纸板之间应该预留大约3mm的空间向外折叠，在向内折叠的纸板之间几乎没有空间。同时，向内折叠的地方用工具刀稍微切割一下皮革，使皮革更容易折叠。确保你没有彻底切断它！
将铝箔纸粘合到内面
创建一个触摸传感器，感应是否有人正在触摸或抚摸狐狸。将4层铝箔纸粘贴在里面以便制作成电容式传感器。对于 Arduino 电容式触控开关原理可以参考这里。将长边缝合在一起然后将铝箔纸粘在纸板上。确保内部折叠部分留出一些空间，以便铝箔纸不会破裂。预留一个地方连接到 Arduino 的接线处。

1、将齿轮粘连到步进电机和胶合板的下面，并将步进电机粘在上面。2、使用针和线，每个角内折叠，形成狐狸的形状。3、将电线缠绕步进电机本两圈，然后稍微拉紧一下。另外，确保可逆时针旋转。
组装所有部件
部件布局如下：1、底部预留9伏电池的地方。2、中间为步进电机。3、顶部为Arduino pro micro和电机驱动器。4、将皮革的开口边缘缝合在一起。
最后，将所有剩余的开口侧缝合在一起，项目就完成了。你还可以连上 USB 数据线，对小狐狸重新编程做一番个性化的调整！
