Assembling the Enclosure

Now we will connect the circuit board you just soldered to the rest of the hardware and to the enclosure, the jar.


  • Circuit board from previous step
  • The rest of the parts not already connected to the circuit board
  • Necessary tools:
    • Drill or some way to put a few holes into the lid of your jar
    • Wire strippers (knife or scissors will do)
    • Wire cutters (knife or scissors will do)
    • Soldering Iron
    • Solder

Putting it all together

  1. Drill a hole for your potentiometer to mount to the lid of the EnerJar
  2. Drill two holes for the power cable to fit through
  3. Drill a hole for the mounting bolt which connects the lid to the circuit board
  4. Mount the bolt to the lid
  5. Mount the circuit board to the bolt
  6. Mount the potentiometer to the lid
  7. Solder the potentiometer to the wires that were soldered into place earlier
  8. Solder the power line wires to the wires that were soldered into place earlier
  9. Make sure that everything is wired and close the EnerJar

You now have an assembled EnerJar, ready for testing.
