B station’s clever Kason version of the walnut shake control panel (base plate)

The mechanical mechanism of the walnut shake refers to the witty Kason of the original up @b station. Address:

Bottom plate function: speed adjustment 

This dashboard requires 

1. Bluetooth 5.0 module purchased from risym flagship store

2.1206 chip resistor:

   0Ω (no need, short-circuit directly)*1

   4.7Ω*1

   10Ω*1

   You can buy it at risym mall, but I recommend buying it at risym flagship store together. Just search for 1206 chip resistor

3. Hexagonal brass post M3*5mm, three M3 flat head screws and nuts (his store also has them, I am not advertising...)

I don’t have a jumper at home, but you can buy some with thin wires... you’ll need to use them.

4. 1506 polymer lithium battery 360mah 21.5*46mm size

    I purchased it from Lihua Electronics (not an advertisement, just for reference)

The Bluetooth module has a battery management function that can directly charge lithium batteries. Please see the merchant details page for details.

Finally, you get a walnut that can play BGM (I didn’t draw the speaker...remember to connect it yourself)
