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
• Utility Knife

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
• CAT5 internal 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

Product¶

(1) Holoseat Sensor Board

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 three joints to cover them completely
   7. 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 15 cm each of the following colors of Cat5 internal wire: Blue/White, Green, Brown, Brown/White
   2. Strip one end of each length of Cat5 internal wire to allow for soldering
   3. Cut approximately 20 cm each of the following colors of hookup wire: (2) green, (1) red, (1) black
   4. Strip one end of each length of hookup wire
   5. Solder the hookup wire to the Cat5 internal wire using the following steps
      
      1. Wrap the stripped end of the Brown Cat5 internal wire around the stripped end of the red hookup wire to create a secure physical connection
      2. Apply solder to the joint formed in the step above to secure the connections between the Brown Cat5 internal wire and the red hookup wire
      3. Wrap the stripped end of the Brown/White Cat5 internal wire around the stripped end of the black hookup wire to create a secure physical connection
      4. Apply solder to the joint formed in the step above to secure the connections between the Brown/White Cat5 internal wire and the black hookup wire
      5. Wrap the stripped end of the Green Cat5 internal wire around the stripped end of a green hookup wire to create a secure physical connection
      6. Apply solder to the joint formed in the step above to secure the connections between the Green Cat5 internal wire and the green hookup wire
      7. Wrap the stripped end of the Blue/White Cat5 internal wire around the stripped end of the other green hookup wire to create a secure physical connection
      8. Apply solder to the joint formed in the step above to secure the connections between the Blue/White Cat5 internal wire and the other green hookup wire
