We've renewed our website
We have fully renewed the YAGI DENKI website — refreshed design, faster loading, mobile support, JP/EN switching, and migrated blog. Built with the help of the AI coding tool "Claude Code".
NewsTechnical notes and happenings around PLCs, control, Raspberry Pi, and our in-house apps — posted now and then.

ReviewWith a business trip to China coming up next month, I went to apply for a commercial/trade (M) entry visa.
Business tripI made an enclosure like this with a 3D printer, put a display and relays inside, and finished it up.
Raspberry PiFor now a GUI like this is done — current time and temperature shown; pH sensor not yet implemented.
Raspberry Pi / GUITo display the current temperature in real time, the temperature needs to be read at regular intervals.
PythonTo build a graphical user interface in Python, we use a library called TKinter.
Python / GUIIt all starts with reading temperature. The sensor is a 3-wire type, with the signal line on GPIO4.
Raspberry PiNext we need outputs to drive the relays — which is remarkably easy using a library.
Raspberry PiI currently manage the workshop aquarium with a spare PLC and a Mitsubishi GOT touch panel.
