SEELab - 3.0

Tested on Ubuntu 18.04 and Windows 7/10

A Python powered tool for learning science by exploring and experimenting.

100+ documented experiments and easy to add more.

4 channel Oscilloscope, 1Msps, +/-16V input range. Programmable voltage ranges

Sine/Triangular Wave Generator, 5Hz to 5kHz. Programmable voltage sources, +/5V and +/-3.3V

Supports Add-On I2C/SPI sensors for pressure, humidity, temperature, angular velocity, luminosity, magnetic fields, and more.

Frequency Counter and time measurements.

12-bit analog resolution. Fully calibrated

SEELab 3.0 is the upgrade to ExpEYES17. It features a 40 pin connector, with an integrated breadboard slot for ease of use. External sensors can be connected via a single AUX cable.

Create circuit diagrams in Inkscape/PS and save as plain SVG

Open with the SEELab3 Android app, and watch dynamic content being generated

Text such as PV1, WG, A1 are replaced with controls, and meters. Intuitive User Interface.

Automatic parameter sweeps, and graphs are also enabled

I2C sensors can also be added . e.g `BMP280:1` will render as a pressure guage

Derived parameters can also be input as equations !

On the right is a schematic diagram for a diode clamping circuit.

This feature is under active development, and 30+ electronics schematics have already been added to the app.

VL53L0X is an easily available optical ranging module with an effective range of around 1 meter. Using the VL53L0X as an example, this post will demonstrate how to add a sensor to the android library so that it is automatically detected by the interactive schematics.

HY-SR04 is a widely available ultrasound ranging module. It consists of two 40 kHz Piezo crystals, where one acts as a transmitter and other as a receiver, and some electronics circuitry is inbuilt to measure the time interval between a burst of sound transmitted and the echo received. This module can measure distance with around 3mm Accuracy, and can be applied to study mass-spring systems, pendulums, and other similar mechanical systems.

Circuit diagrams can be boring sometimes, and ExpEYES has tried to make them more appealing by making them dynamic and interactive. As can be seen from the cover image, this means that voltmeters in the schematic show values in real-time, the function generators can be dynamically adjusted , and derived parameters such as currents are also calculated and updated continuously.
