When we satisfied [Amy Makes Stuff] at the 2019 Hackaday Superconference, we were instantly impressed with the array of flexure mechanisms displayed on a board hanging around her neck. That must be where we saw [Amy]’s original version of the feline calendar — a simple method to understand for sure whether the shared house’s feline has been fed once, twice, or not at all on a provided day.
Left: a simple flexure that gets heavily stressed when actuated. Right: a somewhat more challenging flexure that utilizes less force.
Awesome as it is, the flexure system doesn’t reset the yes/no signs when the day clicks over — that has to be done manually. So when [Amy] was offered to try a little desktop CNC, she decided it was time to make a new version that resets automatically. inspect it out in the video after the break, which likewise includes an exploration of [Amy]’s option of flexure style in addition to a benefit evaluation of the CNC.
This is just an all-around fantastic video, particularly after [Amy] neglected to mill out the inspect marks as well as circles, sending her down a rabbit hole of attempting to make branding bits for these that might be chucked into a soldering iron. Unfortunately, the mill stops short of having the necessary nerve for milling metal.
Although [Amy] is likely understood for her flexures, she has a ton of skills. keep in mind when she resurrected that burned as well as bubbled laser cutter? Or the time she machined a honing jig for hand-sharpening chisels as well as planes?
