A dedicated DIY force curve measuring machine designed and 3D printed by Romly.
The rig features a stepper motor, a load cell, OLED display and 7 buttons to operate the device and SD card to store the data.
Here is the full article in Japanese. (I have to say Google Translate is pretty useless this time.)
- It has a load cell in the moving part.
- Measures the force during the release phase too.
- The measurement data is saved in a CSV file onto the SD card.
- The zero position (measurement start) is determined automatically.
- Measurement intervals between 0.01-1mm.
Unfortunately, it's not open-source, take it as inspiration.
#自作フォースカーブ測定器 名付けて #軸の秤 が動いてるところ。やっぱりOLEDディスプレイ最高過ぎる。M5stack卒業した甲斐がある。はー1bitしかない解像度も低い最高。それに測定値もこれなら十分ちゃんと測れていると思う。#軸の本 #自作キーボード #MechanicalKeyboard #Arduino pic.twitter.com/td7PlI6gPK
