How Much We Have Invested so Far

Most publications don't have a decent methodology for reviewing power supplies for two reasons. The first is lack of knowledge. And the second is not willing to invest money to build a lab for testing power supplies. We decided to break down exactly how much money we have invested to date to build our lab, so you can have an idea of our commitment in reviewing power supplies and bringing you with real information about this hardware part. The costs listed below include tax and shipping, when applicable. We are not including the costs of items like solder, tools like screwdrivers and pliers, the computer necessary for using the oscilloscope, etc. We hope this list also helps other publications to build their own lab. Just don't forget to mention who was your source!
