Step 8Attach Main Board to Sensor Board
You now need to expoxy the main board and sensor board together.
This will obscure the soldering of your sensor board so make sure it is all done correctly and that nothing is short circuiting!
Place the main board into the lighter (make sure the red LED is snuggly in place, now sparingly spread some 2 part epoxy across the top edge of the main board, then place the sensor board into the body of the lighter.
Important! you don't want to glue the boards into the lighter. You are just using the lighter to the line the boards up!!
Once the glue is cured take the two boards out. Don't try to pull the board out from the top, instead use a toothpick to push the board out from the bottom (through the LED hole)
For now the join between the two boards may be a bit flimsy but just be careful with it and resist the temptation to add any more epoxy until the end.
Take the loose wires from the sensor board and solder them into their places on the main board.
