Step 4Cutting the Stripboard
You will need 3 separate boards. One to hold the sensors in the top of the main body, a large board hidden inside the main board to hold the chip, red LED and resistors as well as a board in the lid to hold the switches and batteries.
For the battery board you need 11 strips of 4 holes.
Sensor board 14 strips of 4 holes.
Main board 14 strips of 8 holes.
The two smaller boards need to fit well, so cut them larger than you need and trim / file them down to size.
The boards shouldn't be too hard to get in and out. the battery board is held in by a screw and the sensor board is held down by the hinge so they don't need to be push fit.
With the main board copper side up cut one square out of the bottom left of the board (this is where the red LED will go)
The battery board is attached into the lid with a small screw. at the far left of the board (see illustration) you need to drill a hole for it.
You can also see the slits for the battery contacts but these will depend on what contacts you are using.
