Logic Gates with Diodes #ExpEYES

1.Half wave rectifier Half wave rectifier without filter The half-wave rectifier without a filter experiment using ExpEYES demonstrates how an alternating current (AC) signal is converted into a pulsating direct current (DC) using a single diode. The AC input is applied to the diode and load resistor, and the

AC , DC, and Transients ! #SEELab3

1:HALF WAVE RECTIFIER WITH FILTER The Half Wave Rectifier experiment demonstrates how a single PN junction diode converts an alternating current (AC) signal into a pulsating direct current (DC) by allowing only one half-cycle of the input waveform to pass. Using ExpEYES, the AC input is supplied through the

Acoustics and Diode Experiments

Full Wave Rectifier: With and Without a Filter A center-tapped full wave rectifier built with two diodes, studied with SEELab3 — first without a smoothing capacitor, then with one added across the load The setup uses SEELab3's WG and its inverted output as two 180°-out-of-phase sources, mimicking a

LCR Series Response and Transient Analysis with SEELab

This tutorial walks you through analyzing the steady-state frequency response and transient step response of a series LCR circuit. We will design the circuit, calculate the theoretical values using an online simulator, and validate them with real-world hardware using SEELab. Here's a video of the whole process with

Scientific instruments as state machines: A case study, SEELab 3.0

The SEELab 3 hardware SEELab is a USB powered, multi-purpose data acquisition and control instrument that can be used to automate various test and measurement tasks via its companion android app, or desktop software. It is primarily intended for use in Physics and electronics laboratories in order to enable students

Calibrating SEELab’s Analog Features for Maximum Accuracy

The hardware design of SEELab-3.0 aims to achieve the maximum possible performance from a very conservative bill of materials. There are several analog components such as Op-amps, voltage dividers, and level-shifters involved in input signal processing that have inherent offsets and slopes that must be corrected in order get

GammaSpec-V2: Portable Spectrometer with 2" NaI scintillator, PMT, 2K MCA

This compact unit is USB powered and consumes around 200mA including the HV and electronics. The MCA is a 2K channel list mode acquisition device which also supplies the HV signal via an adjustable DAC. The low power consumption ensures that it can be runs off of USB power for

Engineering a 16K Multi-Channel Analyzer for High-Purity Germanium Detectors

In nuclear physics and radiation metrology, the quality of gamma-ray spectroscopy hinges entirely on two import sections: the fundamental resolution of the detector crystal and the precision of the processing electronics. While standard Sodium Iodide (NaI(Tl)) scintillators perform well within the bounds of a 1K or 4K Multi-Channel Analyzer

Experiments with MTP10-A6F55D PIR temperature sensor

Connections: Connecting for I2C communication is straightforward. Use CS1 for power supply since the sensor can only take up to 3.6V max power supply. The user interface in the sensor logger will show 3 gauges : Object Temperature : Temperature derived from the incoming long range IR light. Ambient Temperature: Temperature
