Hi, I have successfully connected Arduino, Ultrasonic sensor and Hitec HS-311 Servo Motor (Torque (Kg-cm/Oz-in): 3.7/49).
I bought this IKEA stainless steel bin (product name: strapats).
I'm trying to attach the servo on the cover and open it. I try to apply the force at the back, I tried also at the front. Still, the force required seems to be much higher.
My wife does not allow me to buy some servo for 65 USD or more. Because that is close to the price of the whole solution. We invested in this trash bin from stainless steel and complete smart bin cost around 100 USD.
Is there any trick how could I make it open? Some pulley, shaft, vertical movement from the inside of trash or some mechanical hack how to get a smaller requirement for the force to open the lid?
Picture: cannot attach webp, found only chinese Ikea, lol: https://www.ikea.cn/cn/en/catalog/products/60245410/
