A DIY Proximity Sensor, Using Just Scrap Parts And Software
https://hackaday.com/2024/07/01/diy-proximity-sensor-using-just-scrap-parts-and-software/
[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.
The prototype has a threshold set via potentiometer for convenience.
The basic idea is that it’s possible to measure a capacitor’s capacitance using two microcontroller pins and the right software, so by using a few materials to create an open-style capacitor, one can monitor it for changes and detect when anything approaches enough to alter its values past a given threshold, creating a proximity sensor.
The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

UNDO ARDUINO ENCRYPTION WITH AN OSCILLOSCOPE
https://hackaday.com/2024/07/14/undo-arduino-encryption-with-an-oscilloscope/
Cryptography ain’t easy. Seemingly small details like how many times a computationally intensive loop runs can give the game away. [Lord Feistel] gives us a demo of how this could work with nothing more than poorly designed code, a resistor, and an oscilloscope.
