This is the construction instructions for the AnalogIn4 (rev. D) RoboBrick. The status of this project is work in progress.

AnalogIn4 RoboBrick (Revision D) Construction

The instruction steps for building the AnalogIn4 (Rev. D) RoboBrick are listed below:

  1. Orient the board so that it is vertical. By convention, north is the upper edge, south is the lower edge, west is the left edge, and east is the right edge. N1 should be in the north west corner. [Step 1].
  2. Take a 1×5 male header and using some diagonal cutters, snip off pin 2 using the diagram below:
    1 X 3 4 5
    Pin 2 is the pin marked with an `X'. Install the 1×5 male header into N1 with pin 1 to the left. First, solder only one pin and verify that the connector is pointing straight up. If not, use the soldering iron to melt solder around the pin you just solder and reposition the header so that it is pointing straight up. When you are happy with the position, solder in the remaining 4 pins. [Step 2].
  3. Take a 1×3 male header, orient it so that it is horizontal, and insert it into N3. As in the previous instruction, solder 1 pin, verify that it is completely vertical, and solder the remaining 2 pins in. [Step 3].
  4. Find the 10pF capacitor and insert it into C1. Spread the leads, solder 1 pin, verify that it is positioned correctly, solder the remaining lead, and snip off the excess leads. [Step 4].
  5. Find the 100K trim potentiometer and insert it into R1. There is only one orientation where all three leads will fit straight in. Solder one lead, verify that it is flat on the board, solder the remaining 2 leads, and snip off the excess leads. [Step 5].
  6. Find the 6-terminal terminal strip and insert it into N2. If all you can find is some 2-terminal strips, a 6-terminal strip can be assembled from three 2-terminal strip by sliding them together. Make sure that the wire holes point towards the east. Solder in 1 pin, verify position, and solder the remaining pins. [Step 6].
  7. Install the preprogrammed PIC12C672 into U1 with the notch facing up. (We have highlighted the notch in the construction picture with some while marker.) Solder in one pin, verify that the IC is flat against the board, re-heat and reposition if necessary, and solder in the remaining pins. It is very important that the chip does not get overheated. Use a low wattage soldering iron. Also, solder in one pin at a time and then touch the chip with your finger; if it is hot to touch let the chip cool down before you solder in another pin. [Step 7].
  8. Install the shorting block on N3 on the two pins to the east. [{Missing step8 picture}].
The assembly of the AnalogIn4 (Rev. D) RoboBrick is complete.
