pH meters are scientific instruments used for measuring the activity and concentration of hydrogen-ions in water-based solutions, with the aim of indicating its acidity or alkalinity expressed as pH values. They find application in water & wastewater treatment, pharmaceuticals,...

The electrons movement in electronic components lead to the generation of heat which when beyond certain thresholds, prevents some components from functioning properly and in others could lead to a catastrophic breakdown. For this reason, the topics of ventilation, overheating, and...

Last time we examined how to build  a DIY Reflow Oven controller using the Tiny Reflow Oven Controller v1 by Rocket Stream. However, Rocket Stream recently released the Tiny Reflow Controller V2 and for today’s tutorial, we will attempt to build this second version. The Tiny Reflow...

David Johnson-Davies published another great mini project. It's a Timer based on ATtiny402 and was build to demonstrate the low power sleep mode of the microcontroller. This article describes how to use the new 0-series and 1-series ATtiny microcontrollers in low-power projects, taking...

Low quiescent current, also called supply current, might be an important spec for your power-supply design.. by Paul Rako @ electronicdesign.com Quiescent current is the current that a chip needs to operate even if it’s not delivering power. It’s the bare minimum supply current the...
