Hey Hatch, I’ve been itching to build a dough‑kneading machine that actually measures elasticity in real time—think a smart mixer that tells you when your dough is perfect. How would you design the sensors and get the timing just right?

Sure thing, let’s not waste time on the boring bits. First, hook a force‑sensor or load‑cell to the kneading paddle. That way you get raw pressure data every time the paddle pushes. Then, put a tiny strain gauge on the dough‑bucket wall so you can sense how much the dough stretches. Sync those two streams with an Arduino or Raspberry Pi and write a quick routine that calculates the creep curve—if the force drops while strain rises, you’re getting elastic. For timing, just count the paddle revolutions with an optical sensor or magnet, and use that as your reference period. A simple moving‑average filter will smooth out the noise and give you a real‑time “perfect” indicator. If the dough’s still too stiff, the sensor will spit out a higher modulus; if it’s over‑proofed, the modulus drops. Keep the code lean, throw in a beep when the target elasticity is hit, and you’ve got yourself a smart mixer that doesn’t just mix—it knows when the dough’s done. Give it a whirl and tweak the calibration curve with a few batches; the machine will learn as you go.
