The Raspberry Pi RP2040 microcontroller has inspired a wave of creative projects, from environmental monitors to laser distance sensors. With its low cost, flexible programming options, and rich ...

With just an Arduino board, a DHT11 sensor, and an I2C LCD, you can create a simple yet effective weather station at home. This beginner-friendly project displays real-time temperature and humidity ...

If you were to point to a single device responsible for much of Hackaday’s early success, it might be the Arduino Uno. The ...

We've all heard that "if you want something done right, you have to do it yourself." And that’s usually fine when it comes to ...

The last week of the release continued the same “lots of small fixes” trend, but it all really does seem pretty benign, so I’ve tagged the final 7.0 and pushed it out. I suspect it’s a lot of AI tool ...

Computer Science prepares students to lead in a world experiencing sweeping technological change. Students choosing to major in computer science can look forward to a career in one of the many fields ...

An Arduino library for 7-segment display modules based on the TM1637 chip, such as Seeed Studio's Grove 4 digit display. The TM1637 chip also has keyboard input capability, but it's not implemented in ...

Abstract: We present an all-fiber 770 nm laser module based on second harmonic generation (SHG) in a periodically poled lithium niobate (PPLN) waveguide. The laser module provides an output power of ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...

Abstract: The authors describe a novel configuration for a wavelength selectable laser that provides wide tuning and distributed-feedback (DFB) performance and reliability at a fundamentally low cost ...
