How to increase currents of a transformer
If your the transformer too low current, until you cannot use fully it. It is a pity if you need buy the new transformer. So let’s look at how to modify it to increase current up. But the transformers must be the center trap type as Figure 1, suppose your …
Automatic Reverse polarity switch by Relay.
This circuit is an automatic reverse polarity switch. If we apply DC voltage to a any electronic circuits in wrong polarity. It can be caused by too much current. You must waste time to reverse the new terminal. If your circuit is importance, let’s build this project to your life …
