I recently started a personal project that has panned out very well for me. The upgrade to this project is a redesign that will have no mechanical moving parts. This is where my problem lays. The moving parts I'm refering to are in the form of an on/off switch. I want to move to a "Ribbon-Type" of "Force Sensor" that I've found online.(FlexiForce) My problem is that my strengths lay on the mechanical end of this project. I'm afraid I'm Electronically challanged. My initial design was basically a battery source with Power and Ground going to the small electrical gadget that was turned on and off with a mechanical switch. The "Force Sensor" I'm wanting to upgrade to is a specialty sensor that can be calibrated to activate my small electrical gadget when it senses a specific force of anywhere between 0-100 pounds. I need to make up a circuit that will make this "Force Sensor" activate my small electrical gadget when it senses a force of 50 pounds or more. If there is less force or no force being exerted on the sensor, the small electrical gadget will remain in the off mode. At present, the dimensions of this project are exactly 1"x1"x1.5". Any electrical circuit that I use will have to be equally as small. Because I'm a new guy to this forum, I'm not really sure how much detail in need to convey here in order to get a good answer. I'm hoping that this short initial posting will solicit some insight on that as well. If need be, I can share a schematic emailed to me by my contact person at the website where I came across this "Force Sensor;" just to give an idea of what I'm looking for. I've been told that the type of circuit I'm looking for is relatively simple but, as I stated above, my strength lay in the mechanics of this project, not electronics. I'm hoping someone out there has the know how and the will. Look forward to hearing from you.
