battery-bulbHave you ever wondered what’s inside your mobile phone charger?

Over the last 3 years I’ve traveled to many parts of the world. This means I’ve had to replace the charger for my mobile phone and computer, or buy adapters several times.

Recently I arrived in Sydney, Australia. And I thought – maybe I should build my own charger for my iPhone?

I’ve never studied the details of power supplies before.

So, I decided to dive in and get a good understanding of how to build a power supply.

Then use it to build my own mobile phone charger.

In this first article, I’ll show you how to build the simplest power supply I’ve found:

Keep On Soldering!
