As digitalization has deepened, the use of some tools has declined significantly. For example, paperless office has reduced the use of stationery such as fountain pens and scissors a lot. Japanese maker Ryuta Kobayashi thought about whether he could increase the use of these tools if he could digitize them, so he planned to make a digital scissors.
"Scissors are tools that cut things between two blades. Out of inertia, people have always believed that scissors can only cut tangible objects. But if you cut an invisible thing with scissors, isn't it magical and fun? For example, the power supply of household appliances. Long Tai said.
Long tai continued: "Most remote controls for household appliances use infrared communication. In recent years, some smartphones have also been equipped with infrared communication, so that electrical appliances can be controlled through mobile phone APP. The principle is very simple, that is, let the mobile phone remember the infrared signal of the remote control of the home appliance, and send the same signal instead of the remote control. This mechanism can be easily created with a microcomputer. For example, the M5Stack and a dedicated IR UNIT can be implemented. I'm going to give scissors installers such controls. ”
Due to the small position of the scissors mounting control, Longtai chose to use the ultra-small ATOM Lite from the M5Stack series. Then, Longtai removed the original handle of the scissors, measured the size, and designed and 3D printed the new handle. Then, secure the new handle to the scissors and insert the ATOM Lite, ATOM TailBAT, and IR UNIT.
After assembly, the control program is written and a digital pair of scissors is completed. At this time, when the scissors are cut, the control switch can be touched, the infrared signal is emitted, and the appliance is turned off or turned on. At the same time, this scissors also has the function of ordinary scissors.
