Step 5Putting parts together

Putting parts together
Now its time to actually put all the parts into their new home.

Since we measured exactly, that should not be a problem.

In order to provide some power i had to build my own batteryslot.

My device needs about 4.5V so i put 3 times 1.5V AG4 LR625 377 batteries in series. In order to fix them to stay where they should, i installed a little spring which pushes them together. Soldering the specific wires to their contacts and installing the button is not a big deal.

After wiring everything up, i tested it, and then put the lid (which will hold the heart) on top. Glue again.
