Amplified Shunt for mA, µA and nA Current Measurements
thingiverse
A device designed to measure small electric currents is being developed. An improved version of this project can be found at https://www.thingiverse.com/thing:3092910. This development was largely inspired by David L. Jones' open-source 'µCurrent' project on eevblog.com. Advanced skills in soldering surface-mount devices (SMD) are necessary to build and assemble this device. To ensure successful construction, consider the following hints: - Solder switches with correct orientation as seen in a video. - Verify that current flows from + to - through the shunt resistor. - Measure low side load currents by placing shunts between the load and ground. - Use the tool with a limited power supply at low voltage. Additional parts required for this project include: - A Printed Circuit Board (PCB) created from a .zip file uploaded to your preferred manufacturer. - Parts listed in 'partlist_amplified_shunt.csv'. - 2 x 10 mm Spax screws. A video demonstrating the operation and build process of this device is available at https://youtu.be/wkz311_8YzY.
