I am interested in a design I can use to build a working prototype of a &quot;stomp pedal&quot; designed to help train people to do a particular move for a particular sport. Think of it like this:
The animated GIF file attached to this project (below) shows the following motion of the foot: You are standing forward, legs about a meter apart. Your knees are slightly bent and your lower body is positioned so that slightly more weight is toward your back foot than your front. Your right foot is turned slightly (maybe 10-20 degrees) toward your left. Just slightly. You are up on the balls of your feet. Your right heel is about 10cm above the ground. The exercise is about quickly transferring the weight from the left side of your body to the right side. The way this starts is that the left leg pushes up from the ground, thereby initiating the shift in weight to the right. The right leg finishes off the transfer of weight with a quick and hard stomp of the heel of the right foot onto the ground.
I want to prototype some sort of flat &quot;platform&quot; that can go on the ground and has a &quot;plate&quot; or other surface at approximately the 10 cm level. That plate, like the user&#039;s right foot, is angled up to 20 degrees to the left (toward the left foot). The user&#039;s right heel will rest on that plate. There is resistance under the plate so that when the right foot stomps down, the person using the device has to concentrate in order to shift the weight correctly and stomp, otherwise the plate will not make it down to the platform upon which it sits. It would be nice if there was some sort of sound when the plate hits the platform to indicate to the user that the stomp had been sufficiently forceful.
I am also open to alternative approaches to this like, for example, something that could be placed securely on a shoe and provide the stomping resistance described above. It is important, in either case, that he user will know that sufficient force has been applied. Not enough to just compress a spring or a ball.
I would like to be able to manufacture this product with as many off-the-shelf parts as possible. The winning design will:
1. Require little or no machining (if the base is wood, cutting wood is fine).
2. Have no parts that extend above or to the side of the plate (Some people might naturally rotate their heel when stomping so the device should not inhibit this motion in any way. Perhaps the plate could even freely rotate to permit this axial rotate of the heel of the foot).
3. Use as many off-the-shelf components as possible (e.g. interchangeable springs, if springs are used, to provide different resistances; standardized anti-skid surface for the top of the plate; hinges, something to make a mechanical sound)
4. Inexpensive prototype to build, even in a home shop
Deliverable would be a design draft that helps me understand how you think this could be done, including the kinds of off-the-shelf parts to be used.
I am happy to answer any questions.

“Ryan seemed to naturally go above and beyond, almost anticipating my intent. Additionally, he brought other capabilities to the project that are invaluable for both simulation and rapid prototyping. Outstanding freelancer. I hope to keep working with him. Thank you, Ryan! ”
