Fackelmann Electric Pepper Mill / Stanley Rogers

This electric pepper mill works well, but consumes all 6 batteries (4 AAA indicated on the label :) )at the speed of light, and the motor torque is too low because the battery voltage drops rapidly. I had the misfortune of leaving relatively flat batteries (Duracell eg Duraleak:/  )  in the mill and they leak inside.

All this modification fits into the original housing.

So I upgrade them with printed parts, LiPo battery and a few components:

• 1 Lipo 4.2v battery 32x30x4 mm (protection board must be removed) https://s.click.aliexpress.com/e/_DkvuQTf
• 1 Lipo 4.2v usb-c charger IP2312

• 1 step-up converter 3.7v -> 9V MT3608

• 1 Tactile Push Button 6x6x4.3mm

The assembly is wired and housed in the module as shown in the photo.

an optional  1000µF 16V capacitor help the motor regarding his torque.

The capacitor is located under the step up board

Original screws are used and some glue
 

Happy milling !
