YouTuber Electronoobs has just created an Arduino Nano multimeter device. Using a small OLED screen in combination with the Arduino Nano together with a couple of buttons and 16-bit ADC for precise measurements the multimeter is able to display voltage, resistance, current, and it’s also capable of reading capacitance and inductance. Power is provided by…
The latest Raspberry Pi 3 Model B+ isn’t so “revolutionary” but is filled with custom silicon, new technologies, and it even has a neat embossed RF shield. On the Raspberry Pi blog, James Adams has introduced the MXL7704, a custom chip to supply all the voltages found in the Raspberry Pi, just in time for…
When inserted in the cigar lighter socket, it signals the electrical system’s voltage level by means of a bi-color LED. Especially in the cold season, knowing the battery voltage, when the engine is off, allows us to prevent unpleasant inconveniences, such as a failed engine start; in fact the voltage really makes a…
