Microcontrollers, the heart of all modern electronic gadgets, are increasingly powered with sub-5V power supplies. This complicates the control of external loads powered by higher voltages. The trend towards low voltage supplies is dictated by the fact that modern digital and mixed-signal integrated circuits are CMOS based, and with an ever increasing demand for higher

What is Legion? Legion is a portable energy source with a built-in Organic LED display coupled with a microprocessor. It can charge any USB powered electronic devices. Unlike a traditional portable battery where you’re left in the dark about the state of charge of your battery, Legion learns how you use your electronic devices and displays

Sony’s advance in image sensors appears quite natural: the company has developed a set of curved CMOS image sensors based on the curvature of the eye. A report on the sensors in IEEE Spectrum said that, “in a bit of biomimicry,” Sony engineers were able to achieve a set of curved CMOS image sensors using
Sony inspired by biomimicry develops curved CMOS sensors Continue Reading
Today’s spacecraft subsystems require an increasing number of power rails and supply distributions with loads ranging from milliamps to tens of amps. It is important to choose the appropriate solution to meet the performance and reliability requirements for the target mission. Switched-mode power supplies (SMPS) use energy storage elements such as inductors, capacitors or transformers

In this instructable I’m going to show you how to build your own portable audio transmitter. This transmits FM waves so you could easily get the signals on your mobile phone, radios, etc. As the name and the picture indicates it is very small and is approximately the size of a 9v battery clip. This

So, you have a CNC laser cutter but you want a CNC mill? Problem solved. This project is a small CNC mill that can be assembled from store-bought and laser-cut parts for about $800 without machine tools. (If you have access to a shop with a chop saw and a drill press that’ll be helpful,
Make a CNC mill with a laser cutter Continue Reading
To do something useful, a microcontroller (MCU) must be connected to other devices. This connection is made through input/output (I/O) pins. More times than not, these days pins are multifunctional and can connect to A/Ds, D/As, linear functions (such as op amps and comparators), voltage references, and more. So for the design engineer, protecting these

A while ago we came across a website on infrared remote controls which suggested a simple way to view IR signals using an Oscilloscope. The idea is to use a standard IR Led mounted into a BNC/RCA plug using a spare channel making an Oscilloscope infrared receiver. So we set about ordering the connectors, which
