iLabs Around the World

Electronics Experiments

• Microelectronics Device Characterization Lab (MIT)
  Weblab measures the current-voltage characteristics of various microelectronics devices
  
  
• Dynamic Signal Analyzer (DSA) lab (MIT)
  The DSA allows a user to perform frequency domain measurements on electronic circuits and control systems.
  
  
• ELVIS Lab (MIT)
  This lab is based on the National Instruments ELVIS hardware platform and is used to perform measurements on a variety of electronic devices and circuits.
  
  
• Digital Electronic experiment (Makerere)
  

• Elvis Op-amp experiment (OAU)
  The lab utilizes the Dozen-impedance OpAmp circuit. By placing switches from the switching matrix at strategic locations, the dozen impedance circuit makes it possible to construct up to 6 different OpAmp circuits using a single OpAmp.
  
  
• Digital Logic Gate (OAU)
  
  

Control Experiments

• Inverted pendulum (University of Queensland, Australia)
  Inverted Pendulum is a well known control theory experiment where by control laws are derived and tweaked as to balance a pole much like one balances a broom on their finger.
  
  
• Power Flow Control Generators (RMIT University)
  The variable frequency inverter fed Induction Motor is driving the Generator. Induction motor represents the Turbine in real life situations. The generator is loaded. Induction motor is driven by V/F inverter. This controls the torque provided on the generator shaft. With increasing torque the real power generated goes up. When the field voltage is increased the reactive power generated by the generator goes up but not the real power delivered.
  
  

Physics Experiment

• Force On a Dipole Experiment (MIT)
  This experiment consists of a small magnet suspended vertically by a spring in the center of two horizontally mounted coils. We use a video camera set in a position to observe the oscillation of the magnet. LabView software from National Instruments is used to both generate and allow the remote choice of control voltages, waveforms, and for monitoring current and outputting a data stream.
  
  

Spectrometer Experiments

• Neutron Beam (MIT)
  Demonstration of Half Thickness or Shielding Effectiveness in a Neutron Beam.
  
  
• Maxwell Boltzmann Distribution (MIT)
  Measurement of the Maxwell Boltzmann Distribution of Thermal Neutrons by correlating the temperature of the reactor with the availability of thermal neutrons for measurement.
  
  
• Bragg Diffraction and the DeBroglie Wavelength (MIT)
  Demonstration of Bragg Diffraction and the DeBroglie Wavelength using a crystal monochromater.
  
  

Telecommunications Experiments

• Nyquist Sampling Theorem (Makerere)
  
  
• Pulse Code Modulation (Makerere)
  
  
• Line Coding Schemes (Makerere)
  
  
• Amplitude Modulation (Makerere)
  
  
• Frequency Modulation (Makerere)
  
  
  
  

iLabs in Development

• Elvis v2 (MIT, collaborating with OAU)
  
• iLabs Mini (MIT, collaborating with OAU)
  
• Scanning Electron Microscope (OAU)
  
  

iLabs no longer available

• Heat exchanger experiment (MIT)
  
• Shake Table experiment (MIT)
  
• Polymer Crystallization lab (MIT)
  The Polymer Crystallization experiment involves heating a polymer and measuring the rate of crystallization as it cools, in order to draw conclusions about the characteristics of the polymer crystal formation.
