Rohde & Schwarz has paired the outstanding performance of its established R&S RTP oscilloscope with an enhanced user interface and a larger display. The result is an even more flexible oscilloscope in a compact format with a modern look and feel that continues to deliver...

The project presented here is a high common-mode current sense amplifier with two high-speed comparators to detect out-of-range current conditions. The comparators are configured to detect and respond to dual over current conditions. These devices feature an adjustable limit threshold...

The project presented here is an SPI programable Gain Amplifier using MAX9939. The MAX9939 is a general-purpose, differential-input programmable-gain amplifier (PGA) that is ideal for conditioning a variety of wide dynamic range signals such as those found in motor current-sense,...

This is an under-speed sensor module that provides an audible warning and signals output when the speed of a machine is below the set point. The module can be used in applications such as Engines, Machines, Sports machines, Fitness Equipment, Speed of the machine or engine can be...

Oscilloscopes are one of the most essential laboratory tools for electrical engineers. These scopes graphically display varying signal voltages on a two-dimensional plot as a function of time. The waveforms can be used to analyze useful signal properties like amplitude, frequency, rise...

Joseph Eoff has posted on Hackaday details about Rodriguez, which is an IV tracer. About the origin of the project, he says: “Rodriguez started as a nameless project I used to make a point in an online discussion about the shape of the current/voltage plot of the base/emitter...

A dosimeter is an extensively used device for measuring ionizing radiation. Modern electronic personal dosimeters can be worn by a person to monitor the dose of radiation received. These modern dosimeters can give a continuous readout of cumulative dose and current dose rate and can...

The project described here is a 3-Phase isolated Hall-effect current sense amplifier with +/-600-V working voltage range. The current sensor senses magnetic flux generated from current passing through the lead frame at common-mode voltages 0 to 600V DC and provides proportional output...
