The photograph shows a one-inch, single-crystal lead sulfide (PbS) film wafer (left). The right panel demonstrates a clear infrared image of a university emblem and Chinese characters, captured at ...

The Mini2Plus V2 packaging looks like this. The inner box was pitch black. When you open the inner box, you'll find an instruction manual, warranty documents, and a hard case. The instruction manual ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

This is a DIY Arduino-based overcurrent relay project that emulates Inverse Definite Minimum Time (IDMT) protection using an Arduino Nano and ACS712 current sensor. Instead of traditional ...

Total mastery over the pinout and functionality of the PCA9306 for conversion of logic levels from 5V to 3.3V. A step-by-step interfacing diagram for the PCA9306 to Arduino UNO. Working example with ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor module. Given the power of microcontrollers these days, it was only a matter ...

Raspberry Pi launched a follow-up to its Camera Module 3 with the Camera Module 3 Sensor Assembly. Now, Raspberry Pi users can put the camera sensors into their own custom form factors. The move ...

The visible light spectrum that humans perceive spans only a small portion of the electromagnetic spectrum — roughly 430 to 750 THz, corresponding to wavelengths of ~400-700 nm. Just beyond this range ...

Grilling a steak to the perfect medium-rare. Roasting a whole chicken without drying it out. Smoking a brisket low and slow until it’s melt-in-your-mouth tender. Whether you’re a home cook or backyard ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Raspberry Pi is better known for its single-board computer with a ton of ports sticking out. The most recent of which is the Raspberry Pi 5, which was introduced in September 2023. These small ...
