Relays are often used as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. On the other hand, the power dissipation in a relay coil may be unattractive for battery-operated applications. You can lower this dissipation by adding an analog switch that allows the relay to operate at a […]

So this is my microbot V1 which is an ESP32 based robot which is powered by a Wemos d32 pro and controlled by Blynk. Its body is a 3D printed square surface that has mounting holes for the same size PCB which is mounted with this setup in the sandwich config to hold the battery
The release of mini-laptops with display size in the region of 9″ has seen a surge in recent times with several companies like CHUWIX, One Mix, and a few others releasing quite a number of these PCs. To join these growing number of PCs, the Mag1 is joining the fray with the MAG1 “Magic Small” mini laptop. Running on an Intel

Microchip announces a new family of Serial Peripheral Interface (SPI) EERAM memory products, branded as “EERAM Memory Solutions,” that offers system designers up to 25 percent cost savings over the current serial Non-Volatile RAM (NVRAM) alternatives. The family introduces four reliable SPI densities to Microchip’s EERAM portfolio, ranging from 64 Kb up to 1 Mb
EERAM MEMORY SOLUTIONS REDUCE MEMORY COSTS AND RETAIN DATA AT POWER LOSS Continue Reading
The widespread adoption of the CAN bus (and OBD-II) in automobiles was largely a way of standardizing the maintenance of increasingly complicated engines and their needs to meet modern emissions standards. While that might sound a little dry on the surface, the existence and standardization of this communications bus in essentially all passenger vehicles for

If a robot is rideable, is it still a robot or is it a vehicle? We would argue that if it rolls on standard automobile-style wheels or even tank tracks, it is a vehicle. But James Bruton’s eight-wheeled robot snake bike is quite clearly something else. This “vehicle” started as a small functional model that
This snake robot is large enough to ride upon Continue Reading
Thanks to their high accuracy and fast load recovery time, the R&S®NGM200 power supplies are perfect for challenging applications. Their two-quadrant architecture allows them to function both as a source and a sink to simulate batteries and loads. Their short recovery times enable them to handle fast load changes that occur, for example, when mobile communications devices
