#_5 Stupid Pet Trick

Edit: Alright, now it's working! Wirewrapping is the way to go. And if NASA does it, who could resist. The new sensor needs different thresholds, which aren't adjusted yet properly so the LEDs and the buzzer trigger a bit too easily. Will upload a video asap.

The idea was to have a FSR, a Force Sensing Resistor, detect touch pressure during human interaction... this concrete example aimed to measure the strength of a handshake and respond along two thresholds: red LEDs = 180 and buzzer = 280. In the bigger picture it might be a great tool in the context of assistive technology, i.e.: people with autism or other mental/neural disorders could create their very own threshold that prevents people from touching them too hard or inappropriately according to their perception.



























Okay, while assembling and actually making the cutting edge design of my stupid pet trick, my freakin' FSR broke. Let that one be a lesson: do not solder FSRs unless they aree in a spot where no force is applied to the sensor as a whole. So off to the shop I went and got a new one. Though, now I am not sure where exactly to put it.
