Hey everyone, I've been messing around with this small-scale kinetic piece lately—trying to get these delicate arms to move in sync with sound inputs, super subtle stuff for an interactive wall thing I'm building in my garage. But man, finding the right mini actuators has been a headache. The tiny ones I grabbed off the shelf keep stalling under even light loads, and the speed feels either way too jerky or painfully slow for the fluid motion I'm after. Anyone here have experience with these in actual art installs? What are the biggest design headaches you've run into—like force vs size trade-offs, backlash in the mechanism, heat buildup during longer runs, or maybe power draw messing with battery setups? Curious what limitations you've actually hit in real projects rather than just specs on paper. Last weekend one seized up mid-demo because of some binding I didn't spot early enough... total facepalm moment.
