Really interesting writeup. The contraption has parallels to some of what we do with software: automating a legacy system without completely reinventing it. For such an accomplished practitioner, the author made one glaring mistake: > We will use one solenoid on each side of the snares, thus doubling the force Clearly they have a system with one solenoid pulling from each end of the same thing. This does not increase the force at all. Pulling on a rope with one end fixed is just as good as pulling on both ends (from the rope's perspective there is no difference).
