Section Three Soldering

After you assemble a circuit on a breadboard, would you like the option to make a permanent version? This would mean relocating the components and joining their leads together with little droplets of hot metal alloy known as solder. The process is known as soldering, which is much easier than it sounds, because although solder does get quite hot, it can be applied safely in tiny amounts.

I’m going to take you step by step through the soldering process, and will show you how to make a permanent version of the flasher circuit that I described in Experiment 11. I will also suggest a power supply that you can use to eliminate the need for batteries throughout the rest of this book. This will be helpful for some circuits which ...
