Introduction While building microcontroller based projects, there are occasions where communication will be required between two devices, either in a duplex/transceiver based operation (wher... Read more
As a consequence of the social distancing and self isolation, many a maker has been searching for ways to cure boredom. So what happens when you put a maker in a closed space with electronic... Read more
Multifunction data-acquisition systems have been around for a long time as stand-alone instruments, plug-in cards, cabled computer peripherals, and embedded in systems. Such systems are ofte... Read more
Introduction Previously I made a simple frequency-modulated continuous-wave (FMCW) radar that was able to detect distance of a human sized object to 100 m. It worked, but as it was made with... Read more
Open source has finally arrived to microcontrollers. Based on RISC-V instruction set, a group of doctoral students at the Universidad Industrial de Santander in Colombia have been working on... Read more
Orlando Hoilett from Calvary Engineering LLC designed a versatile Li-Po battery breadboard power supply and wrote an Instructables on it. This power supply outputs 3.3V to the breadboard an... Read more

Arduino boards are very useful for beginners to get started with building hardware projects. But at some point, more powerful controller than the Arduino’s 8 MHz one will be needed, featurin... Read more
Actual microcontrollers have powerful bidirectional I/O ports, and you can use different techniques to fully exploit such capabilities. Recent Design Ideas described the “Charlieplexing” met... Read more
When you connect a microcontroller to a sensor, display, or other module, do you ever think about how the two devices talk to each other? What exactly are they saying? How are they able to u... Read more
Most of us who work with electronics know the name of Texas Instruments (TI) as a manufacturer of several important digital and analogue ICs as well as fancy sophisticated scientific calcula... Read more
Introduction This is a small bench power supply that is powered by two lithium-ion batteries. The project was inspired by Dave Jones from EEVblog but the design is completely mine. The volta... Read more
