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...

This Mini Audio Power Amplifier is capable of delivering 1W of continuous RMS Output Power into 8 ohms load @ 5V. The Amplifier is built using TS4871 IC from ST.  This Audio Amplifier is exhibiting 0.1% distortion level (THD) from a 5V supply for a Pout = 250mW RMS. An external...

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,...

With IoT expanding, developers are begining to desire more communication options to facilitate the exploration of diverse IoT possibilities. This was one of the reasons why the announcement of partnership between Chirp and Arduino was received with so much enthusiasm by the makers....

Several of our past tutorials looked at the possibility of building the hobbyist version of several important tools and equipment used by different categories of makers. We have explored how to build the DIY/Hobbyist versions of seemingly easy tools like a voltmeter to more complex and...

Reflow ovens are an important part of the development of PCB for electronic products when using surface mount components. They provide a route through which PCBs can be quickly populated with SMD components, however, for accurate results, the heat across the oven needs to be controlled...

A few years back, Microchip/Atmel announced the release of a completely new range of chips designed to serve as replacements for their older ATmega and ATtiny ranges. The new ATtiny chips started with the 1-series which included ATtiny417 and ATtiny817, which was followed in 2018 by the...

Connectivity continues to be one of the most important features of any device in recent times, even for devices that are not directly connected to the internet, the need to send data from one device to the other is an important part of the ubiquitous world being built today. For...
