Also, a very old technique could be used to indicate only the dynamic change in resistance, by exciting the graphite string with a constant current source and measuring the voltage drop through a capacitor which produces an AC signal proportional to resistance change. This was the technique used before stable DC amplifiers were available.
The idea would probably benefit by using a "Kelvin" type connection with 4 wires connected to the graphite string... Two wires supply current across the string and two sense the voltage drop with a high impedance device...I have used this technique many times in the past for precision resistance measurement.
Would you be able to do this by putting graphite on rubber bands or on those stretch cloth strings (tightly knit cloth outside, stretchy filaments on the inside) to make a smaller tension sensor with less parts?
este hombre es increíble, no puedo parar de ver sus videos
saudações do Brasil (hello from Brazil)
酷耶！省錢又實用

This is awesome man! Thank you for the very detailed video!
感覺可以用來做賽車方向盤 取代類比搖桿
thanks man!
可以請教您這篇的動畫人物的Processing code嗎？謝謝！😋
真棒 ! 學到了 感謝 !
请问黄老师了解如何（用导电的铜胶带）制作可以加热的模块吗？

為什麼我做出來的感測器序列部監控出來是波的形狀不是一條線 是跟鉛筆有關係還是我磨的不夠 (可是我已經磨得很均勻了)
黃老師您好！我是看到您的影片才知道Processing用來呈現Arduino效果這麼好的！我目前也在做Arduino搭配Processing的專案，要用Processing做出3D來呈現Arduino的訊號輸入，可以請教您這篇的動畫人物的Processing code嗎？謝謝！
這種拉力感測器讓我直觀的聯想到wii 這種感測器是用在機器人身上的數質數據嗎?
應用想到空速管，哈哈
This is extremely cool! Very smart!
Hi there, just wondering do you have the code for this application? Will be awesome to try it out myself :) Thanks alot
請問石墨的部分可以用導電墨水替代嗎?
贊啦！！
讚
老師請問這個 板子哪裡買的到呢
實體電子材料行，或是網路都可以買到，Arduino Uno 這個型號比較好買
每個被題名人應該對廢死問題表態
这款感测器寿命如何？
awesome!
Brilliant!

我試過口罩上的彈力繩，效果很差，呈現的數值不是線性的
@@davidhuanglab Ah, I see. That's too bad. Thank you for responding!
Wtf this is brilliant!
