    Thanks for the quick response! I have another question: how do you recommend that someone find an appropriate motor for this project? I already built the whole thing, but unfortunately, the motor I used is WAY too strong and the rubber band has no effect on it since the magnets are strong and it takes significant force to turn the armature. It doesn’t stop at the bottom like it is supposed to, the motor just keeps going, reeling the spider back up the wrong way. You said that the motor you used is from a floor sweeper, so you obviously don’t have any specs on it, but is there a test that people can do to see if a motor is too strong or weak without having to construct and glue on a new reel each time they try a new motor?

    how does the motor not burn out then if someone just stands under the sensor for a long time? As you said, the motor isn't strong enough to pull the spider up, so won't it just draw more and more current which will eventually ruin the motor?
