We have 3 live demonstration circuits which have been built on the demo REL1.0 breadboard board:

RELAXATION OSCILLATOR where the use has variable frequency control and variable amplitude control

DIGITAL LOGIC NAND GATE CONTROL circuit where the user can control the output signal

A familiar 555 IC implementing an astable oscillator where the use has variable frequency control

netCIRCUITlabs Remote labs system delivers real-time control and measurement of real electronics circuits. It functions online to multiple students simultaneously. You need to have a LAN or Internet and the lab is accessible 24/7.

30 or more students can access the server at the same time. Each student can access any experiment on the APPLICATIONS board. The experiments are accessible using each student’s PC, laptop or tablet via web browser.

The netCIRCUITlabs remote hardware is a fully self-contained system. It has inbuilt test instruments including oscilloscope, spectrum analyser, cursor measurements and full function signal generator.

Users get complete control of all circuit switches and potentiometers. Users could select and view circuit waveforms & spectra at multiple test points.

There are 5 to 15 experiments per APPLICATIONS board. Each student can select any experiment on the APPLICATION board.

Experiments covering AC Amplifiers, Feedback Circuits, Differential Amplifiers, SCR Circuits, OTL Power, Amplifiers, Op-amp Circuits, Waveform Generators, Resonant Circuits & Filters, Digital Logic Gates, Combinational Logic and much more

The ‘hands-on’ approach of this virtual lab system builds student confidence. It makes the experiment satisfying as the students are free to explore and learn. When they explore more, they learn more.
