  1. Hi guys,Lovely community here. So i got into the bandwagon of the ESP32. I am planning to build an entire data acquisition built around the ESP32. Would really appreciate it much if i were to get help from all of you. It would be a learning experience for all of us. So basically here are my project details and list of components being used.A 32 Channel Data acquisition system with 30 sensors measuring strain (momentarily using a metal gage strain sensor of 120Ohm being fed to a quarter bridge circuit) and 2 temperature sensors(PT100). I would like an acquisition speed of atleast 1000Samples/Se
  2. Hello. I made this circuit below: http://www.diy-electronic-projects.com/p270-Everything-that-moves-ALARM The circuit does not appear to be working properly, and I would like to get it working. To be honest with you, I never heard of a human body detector using eddy currents. The first image shows the pulses on the gate of the mosfet. They appear to be low duty cycle(around 15-20%). The other images show the pulses received by the smaller coil(5"/100T/26ga enamel wire) placed in the center of the 24ga speaker wire/5 foot diameter (5T) TX loop. The circuit can be set, but you cannot get it to
