In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to ...

I'm currently designing a photodiode array circuit w/ 18 VEMD2023SLX01 (https://www.vishay.com/docs/83493/vemd2023slx01.pdf) photodiode components. Given limited pcb ...

The files for printing the part and the wiring diagram can be found in this repository as well. One of the is *.scad and the other *.fzz Elements needed: IR Led IR photodiode Optional: Color LED Piezo ...

I test it with a water flow sensor YF-402, arduino UNO and Arduino MEGA 2560 and works (precision not tested) TODO: use pin change interrupt to allow every pin. TODO: integrate with pool controler to ...

If I have 25 photodiode and one ADC,how to design transimpedance amp circuit ? I have cost issue,so I can not use 25 transimpedance amp circuit. Could I use analog switch to switch these 25 photodiode ...
