cara upgrade dinamo DC untuk bor mini

How to upgrade a DC dynamo for a mini drill to make it into a mini drill. This method is effective because we don't need to replace the coil wire. I will later use this DC dynamo as a portable mini drill. The mini drill is made from a portable DC dynamo, so it no longer requires a power supply. To learn how to upgrade, please watch the video until the end. Working materials: Soldering iron, tin, scissors, 3.7-volt battery, battery clamp, paper, pen, and calculator That's all the tools we need. Hopefully, this video is helpful.
