DIY Egg Beater: Turn an Old Mini Grinder into a Cake Mixer

If you are interested in making a DIY egg beater, you can take a look at this article.

Suppose you happen to have a small electric grinder that is no longer useful. However, do not throw it away just yet. If you also have a three-speed circuit board from a small fan, you may suddenly get an idea: you can use these materials to make a cake mixer.

First, remove the original switch and install the electric fan switch.

Then, use AB glue to fix it in place.

The circuit board is much larger than needed. After checking it carefully, you find that only the inductor, capacitor, diode, and two indicator lights are necessary, so you can directly cut off the unnecessary parts.

You also remove the motor on the back; otherwise, it will take up too much space.

Then, solder two wires and reinstall the removed components.

You modify the charging port to a Micro USB interface.

After connecting the battery, you estimate that it should still have enough power to whip four egg whites.

Then, you proceed with the soldering, and the charging indicator works normally.

You use a small board as the switch cover, which allows you to press it directly.

Finally, you wrap it with electrical tape and secure it with 502 glue. The DIY project is complete, and this is the finished product.
