Building a Kitchen Timer: Soldering and Finishing

As said in my earlier post, I was building a kitchen timer. I explained the main components needed to make it work and now I got to soldering my first electronic circuit. I had my dad help me out, and according to him, I did a pretty good job, for a beginning beginner  . We started with the middle and worked our way out, until doing the LEDs the whole way around and then the battery. Here are some photos. There aren't many in between the start and end of the soldering because we didn't take any pauses, we just kept soldering.

The Soldering Iron we used, waiting for it to heat up sufficiently.

The Soldering of the buzzer (very middle) and the operating button (left side). Pretty well done huh?

We cut the ends off after each solder, because most of them got in the way.

Now doing the LEDs, one after the other.

Finished soldering everything.

Using the provided screws, I screwed the circuit and battery holder together, and then popped that into the case. This is the finished product, with all the lights on.

Thanks to Dad who took some of the pictures and sacrificed the morning of his day off for me. And thanks to Mum who made this gorgeous apple pie after that didn't even last five minutes on the table. Below is a video demonstrating my awesome new timer.
