This resistor conforms to the MIL-R-26/C ... This suggests that the 9.4 V reference voltage on this PCB plays a key role. I see a precision voltage reference, what looks like a differential ...

What’s your favorite value of resistor? 1K? 10K? They’re all fine, but when you need nearly no resistance at all, nothing beats the good old zero-ohm resistor. Wait a minute! Resistors are ...

A developer has built an open-source multifunctional oscilloscope by repurposing an old Android phone, a Raspberry Pi Pico, and a custom-made PCB that integrates all necessary components. The project ...
