In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

The SGI O2 was SGI’s last-ditch attempt at a low-end MIPS-based workstation back in 1996, and correspondingly didn’t use the ...

Late in 2025, we covered the development of an AI system called Evo that was trained on massive numbers of bacterial genomes. So many that, when prompted with sequences from a cluster of related genes ...

The I2CKeyPad8x8 library implements the reading of a 8x8 keypad by means of a PCF8575. Smaller keypads, meaning less columns or rows (e.g. 5x4) can be read with it too. Sometimes you need to control ...

Arduino sketch for generating pulses needed to control servo drivers such as the AASD-15A used in the SFX100 project and the pt-actuators. The controller is meant for the SFX100 actuator and the likes ...

The impact of AI is already showing up in the data relating to coding productivity. According to recent analysis by FT, year-on-year growth across multiple indicators of coding output has surged ...

Meath County Council and Trinity College Dublin have announced the launch of STEAM Team 2026, an innovative new programme designed to transform how families engage with coding and digital skills in ...
