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 ...

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

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 ...

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: 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 ...

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 ...
