amplifier

Amplifiers
  • Note: The amplifiers are to be used with care. Use them for short periods of time, switch them off when not in use. The gains are not to be cranked up suddenly to a very high value. Increase and decrease the gains gradually. Any breakage should be reported to the TA.

    • Connect to the load output using a 6-pin male DIN connector (Pins 3 and 6 are not connected and pin 7 is actually the shield). Two pins (1,2) should be connected to MA (+) and two pins should be connected to MB (-). Item Number: 5611 PL from www.mpja.com
  • Connection to voltpaq x2 6 pin din male connector

    Diagram on left shows the pin connections to the connector side of the 6-pin female DIN connector on the front of the amplfier. The right side shows the connection side view of the 6-pin male DIN connector, the pins are number counter-clockwise to match the pin numbering on the female connector when connected.

    • Note that MB can be connected to the ground but then you will lose the ability to sense current. It is not recommended to share the output of the amplifier to run one load, i.e. amplfier is not bridgable.

AutoCAD
  • Directions for using AutoCAD with laser cutter. They are fairly basic requirements, but following them will save time and material when cutting. [MS Word DOC]
  • Sample of laser cutter output (penny is for reference) is given in the image to the left.
  • This AutoCAD template [DWG] which should be used for all drawings. It was created to match the dimensions of the cutting area in the laser cutter.
vls 2.30 laser cutter Rhodes 401 Laser Cutter Laboratory - Access Policy
  • The following Authorized Users may access Rhodes 403 and supervise use of the laser cutter:
    • ECE 495 - Ran Huang, Brian Williams, Venkataraman Ganesh
    • ECE 496 - Peng Xu, Jonathan Herr
  • Up to two students may accompany the Authorized User while using the laser cutter. Stay in the vicinity of the laser cutter and do not touch other equipment in the room.
  • An Authorized User must be present at all time.
  • Under exceptional circumstances an individual may become an authorized user by:
    • Obtaining permission of instructor (Timothy Burg, tburg@clemson.edu)
    • Contacting Mr. Scheen Thurmond (sthurmo@g.clemson.edu) for initial assessment of safety training. Be sure to tell him that you will only be using the laser cutter.
    • Complete laser training with Mr. Thurmond
    • Follow and enforce the lab rules inlcuding:
      "Students working in Rhodes 403 with the laser cutter must wear long pants, closed toed shoes, and safety glasses upon entering the lab. Students working in this capacity who are not registered with Clemson University’s Medical Surveillance Program and who have not completed the Research Safety Program are not allowed access to any other IBIOE facilities on the Rhodes 4th floor.
  • See http://www.clemson.edu/centers-institutes/ibioe/SafetyTraining/index.html for complete lab acess rules
  • Updated : 10/17/2013 (TCB)
acrylic sheets Materials
  • Acrylic/Plexiglass is the preferred material; we have tested the cutter with it and have an idea about the settings required by it. Acrylic sheets up to 6 mm can be cut. 8 mm is the specified upper limit, but we cannot be sure the laser will be able to cut through that thickness.

Software

wiimote Wiimote as a camera
  • The Wii remote is useful for vision because it returns data at very high data rates – up to 100 Hertz (Average ~ 90 Hz).
  • Detects upto 4 sources of UV light.
  • The instructions, written by Jeff Forsyth and team during their senior design project, guide the reader through the tasks required to implement the Nintendo Wii Remote as a camera, including learning the basics of Johnny Chung Lee’s software and UDP data transmission (.NET framework C #).

qrcodeQR Code Reader/Writer
  • Code taken from the Matlab File Exchange uses several Java libraries to both encode/decode QR codes.  Here are the functions & example m-files to use for QR reading/writing (remember that the functions have to be in the Matlab current folder or added to the path). For this class, only the decoding of a QR code will be used.
