Navigate to and select "PhotBox_v1d_sch1_2018-07-24.zip"
Click "OK"

Make sure PCB Dimensions are 100mm x 160mm

Select desired color

All other default options should be OK

Order all other commercially available components off of parts list from Digikey,

McMaster-Carr and National Instruments

Order enclosure from your favorite 3D printing service. Note enclosure box and lid are stored in separate ".stl" files

Start with smallest (shortest) components first, then work towards tallest so that board can be flipped-over at each step to solder components in place without them dropping out.

Suggested soldering order

1. Resistors (no orientation)
2. Op-Amp (Notch on Op-Amp should point towards the MBED)
3. Capacitors (no orientation)
4. NI-DAQ connector (connector should point out over bottom edge of board)
5. Power Supply
6. MBED Microcontroller (USB connector should point towards top edge of board)
7. Displays
   1. Place displays into spacer pins (don't solder yet)
   2. Colored dots on side of indicate color of display
   3. Place spacer pins into PCB
   4. Not
      all spacer pins need to be connected (see below). I solder only pins on top row (for electrical connections) and two pins in each bottom corner for structural stability. Remaining pins on edges can be skipped
   1. Solder spacer pins into displays from front face
   2. Flip PCB over and solder spacer pins into PCB
8. Switches (no orientation)
9. BNCs
10. Potentiometers

Undo the three screws on the plastic enclosure of the NI-DAQ USB-6009 card using a phillips head screwdriver. Attach the card to the PCB as shown, with the USB connector pointing to the right as shown.

1. Remove all nuts and washers from BNCs, switches and potentiometers
2. Place the PCB into the enclosure and line up screws
3. Use self-tapping screws to attach PCB and NI-DAQ USB-6009 to stand-offs inside the enclosure
4. Attach nuts to all connectors on front face to affix components in place
5. Attach knobs to potentiometers

1. Connect MBED microcontroller to computer through USB (it will show up as a thumb drive).
2. Copy the binary file "fibPhotBox6_LPC1768.bin" onto the MBED
3. With the box powered on, reset the MBED by inserting a paper clip or fine hex wrench through the small hole on the front of the enclosure to press the reset button

Install the NI-DAQmx software

available here:

National Instruments NI-DAQmx software and drivers

Connect the NI-DAQ USB-6009 to the computer with USB cable and allow computer to install drivers

Note, the NI-DAQ USB-6009 digitizer will interface easily with a wide variety of software, including Matlab. Instructions and code provided here describe use with the freely available Strathclyde WinEDR digital recording software

1. Download and install Strathclyde WinEDR:
   Strathclyde WinEDR
2. Make sure NI-DAQ USB-6009 is connected to the computer
3. Open WinEDR
4. Navigate to Setup-->Laborator Interface Setup
5. Select "National Instruments (NIDAQ-MX)"
6. Set "A/D Input" to "Single Ended (RSE)"
7. Select "USB-6009 (8ch 13bit +-10V ADC, 2ch. 12bit +-5V DAC"
8. Click "OK"
9. Naviate to "Record-->Record to disk"
10. Set "No. channels" to "8"
11. Set "Sampling Interval" to 2ms
12. Set "No. sweeps" and "Duration" as desired. I always set "No. sweeps" to "1", and "Duration" to a time much longer than my recording session will run (e.g. 36000 sec).
