US-based CNC and motion control developer Bart Dring has designed the 6x CNC Controller FluidNC-compatible CNC controller board built around an ESP32 (pre-programmed with FluidNC) module and including ...

Toshiba is aiming at 400V automotive systems with a 400V photo-relay that can handle 900V and ~30mA. Recommended maximum operating voltage is 720V. Called ...

In this paper, a high stability constant current source system is designed, and its output current range is - 100mA~100mA. Firstly, based on the series negative feedback circuit to achieve steady ...

Texas Instruments is previewing a 50V quad-channel single-pole analogue switch with a wide voltage range, low on-resistance and consistent on-resistance ...

The particular design in this study has 20V to 45V step up voltage with 100mA output current rating. In this paper, the DC-DC switching mode topology requires a 20V supply from either a DC power ...

Simple 100mA Constant Current Source using Transistor In this project, we will build a simple transistor constant current source generator using only 4 components. It is a very inexpensive circuit ...

By now, we’ve gone through LiIon handling basics and mechanics. When it comes to designing your circuit around a LiIon battery, I believe you could benefit from a cookbook with direct suggest… ...

Hello, i have new Zigbee RC-RCBO and last version z2mqtt. I write the converter and i can only on/off switch. I do not see info about energy, power, voltage (all null) and when i connect the consum ...

This Milliamp Meter circuit can measure currents of the order of 1mA with better accuracy, and therefore can be useful for DIY projects.

The Department of Environment and Natural Resources-River Basin Control Office (DENR-RCBO) has contracted the University of the Philippines Los Baños to develop the master plan of river basins in the ...
