Introduction¶

Below are the assembly instructions for the v0.3 Holoseat controller. This version is built using an AdaFruit Feather 32u4 Basic Proto. It also includes a remotely mountable sensor board. You will need to use your soldering skills on this build.

Sensor Board Assembly¶

Tools¶

• Diagonal Cutters
• Wire Strippers
• Needle Nose Pliers
• Soldering Iron
• Punch Down Tool

Materials¶

• (1) HS001 - Double-Side Prototype PCB
• (1) HS002 - Category 5e Jack
• (2) HS003 - 750 OHM 1/2W 1% Axial Resistor
• (2) HS004 - OH090U Hall Effect Sensor
• (2) HS005 - Diffused Blue 3mm LED
• Hook up wire
• Solder

Safety Issues¶

• Care must be taken when using sharp hand tools to avoid cuts
• Care must be taken when using the soldering iron, the tip is very hot
• Always wear safety glasses while working with soldering irons
• Avoid breathing in the soldering fumes, use a vent or hood if needed to provide adequate ventilation

Procedure¶

1. Prepare Sensor/LED sub-assemblies
   Repeat this procedure twice to assemble (2) Sensor/LED sub-assemblies
   1. Take (1) HS004 - OH090U Hall Effect Sensor and (1) HS005 - Diffused Blue 3mm LED from your supplies
      
   2. Solder the LED's anode (long leg) to pin 3 of the sensor (the data pin) and solder the LED's cathode (short leg) to pin 2 of the sensor (the ground pin) using the following steps
      
      1. Align the LED to it sits on top of the sensor with the long leg next to pin 3 and the short leg next to pin 2
      2. Wrap the LED's long leg around pin 3 to create a secure physical connection
      3. Wrap the LED's short leg around pin 2 to create a secure physical connection
      4. Apply solder to the two joints formed in the steps above to secure the connections between the LED and the sensor
   3. Cut approximately 40 cm lengths of black, red, and green hook up wire
   4. Strip both ends of the (3) lengths of hookup wire
   5. Solder the hookup wire to the ends of the sensor pins (red to pin 1, black to pin 2, and green to pin 3) using the following steps
      
      1. Wrap one end of the red hook up wire around pin 1 to create a secure physical connection
      2. Apply solder to the joint formed in the step above to secure the connections between the red hookup wire and pin 1
      3. Wrap one end of the black hook up wire around pin 2 to create a secure physical connection
      4. Apply solder to the joint formed in the step above to secure the connections between the black hookup wire and pin 2
      5. Wrap one end of the green hook up wire around pin 3 to create a secure physical connection
      6. Apply solder to the joint formed in the step above to secure the connections between the green hookup wire and pin 3
   6. Apply sufficient heat shrink to the red and green joints to cover them completely
   7. Apply sufficient heat shrink to assembly to completely cover the solder joints of all three leads, leaving some overlapping the LED to give it strain releaf
   8. Apply larger heat shrink to the three leads made from the hookup wire to complete the Sensor/LED sub-assembly
2. Prepare the HS002 - Category 5e Jack
   1. Cut approximately 20 cm each of the following colors of hookup wire: (2) green, (1) red, (1) black
   2. Strip one end of each length of hookup wire
   3. Use a punch down tool to connect the hookup wires to their corresponding positions on the HS002 - Category 5e Jack for pinout option A
      1. Punch down the stripped end of the red hookup wire to Brown wire position of the Cat5e Jack
      2. Punch down the stripped end of the black hookup wire to Brown/White wire position of the Cat5e Jack
      3. Punch down the stripped end of a green hookup wire to Green wire position of the Cat5e Jack
      4. Punch down the stripped end of the other green hookup wire to Blue/White wire position of the Cat5e Jack
         
3. Finish Assembling the Sensor Board
   Reference the image below for the following steps
   
   1. Connect the black leads
      1. Test fit the black leads from both Sensor/LED sub-assemblies and the HS002 - Category 5e Jack, cutting the wires to length as necessary (remember to leave room for the stripped wire)
      2. Strip the three black wires from the step above
      3. Position the three black wires above in the correct holes of the HS001 - Double-Side Prototype PCB and bend them over to create a secure physical connection
      4. Apply solder to the joint formed in the step above to secure the connection among the three black leads
   2. Connect the red leads
      1. Take the (2) HS003 - 750 OHM 1/2W 1% Axial Resistors and position them according to the diagram (making sure to bend their leads to secure them in place
      2. Test fit the red leads from both Sensor/LED sub-assemblies and the HS002 - Category 5e Jack, cutting the wires to length as necessary (remember to leave room for the stripped wire)
      3. Strip the three red wires from the step above
      4. Position the three red wires above in the correct holes of the HS001 - Double-Side Prototype PCB and bend them over to create a secure physical connection
      5. Cut a short length of red hookup wire to bridge the red leads according to the diagram
      6. Strip both ends of this additional length of red wire and place it according to the diagram, bending its ends over to create a secure physical connection
      7. Apply solder to the joint formed in the step above to secure the connection among the three red leads
   3. Connect each of the green leads
      Repeat these steps for each of the sensors' green leads according to the diagram
      1. Test fit the green leads from one of the Sensor/LED sub-assemblies and the HS002 - Category 5e Jack, cutting the wires to length as necessary (remember to leave room for the stripped wire)
      2. Strip the two green wires from the step above
      3. Position the two green wires above in the correct holes of the HS001 - Double-Side Prototype PCB and bend them over to create a secure physical connection
      4. Apply solder to the joint formed in the step above to secure the connection among the two green leads

The Sensor Board is now complete.
