The following are the key characteristics of the ZD10-100:
She scavenged the diode from a decommissioned 1980s seismograph—caked in frost, legs tarnished, but intact. The datasheet’s warned: Storage temperature -65°C to +175°C . The seismograph had sat at -40°C for a decade. Well within spec.
The ZD10-100 functions similarly to a force-sensitive resistor (FSR).

One of the reason I came to Goa was because of Mr. Mario Miranda. My dream has been fulfilled. The high point of my visit, I grew up with Mario and thank you for printing out the pictures and the lovely gift.
