For my project, I chose to build a digital watch. Building the watch included soldering almost everything onto the watch, including the 48 small LED ends, making the battery holder and putting the outer plastic watch part together with screws. I used a watch kit, a soldering iron and other soldering tools, gloves and a fan. The most difficult part about the project was soldering the led ends. At the time, the soldering iron I was using had a very broad tip, making it difficult to solder lots of little things in a very confined space. This was very frustrating at times. The part I enjoyed most was soldering with the solder that had a smaller tip. I could make lots of progress in a very short amount of time and that was satisfying. I learned two things from doing this project: There can be an easier way to do something, if you look for it and never use a soldering iron without gloves.
