DIY Desk Cleaner

A desk will eventually get dirty with time. It is very inconvenient to take all the bits by hand for disposal. To solve this issue, I built a Desk Cleaner by using a brushless motor. This is a very simple project requiring no microcontrollers. So, here is what you need...

Stuff you need (links are for not the ones I used): -

• 5V Brushless Motor
• 3.7v Lithium-Ion battery
• Battery Charging Module
• Switch
• A-Type USB cable

For the box, I am using an old plastic container. To close it (while leaving space for the motor) I took some cardboard and made it to perfectly fit inside the case. I also kept a cloth layer on one side of the cardboard to absorb the dust but this is completely optional.

This is the circuit for the motor. I will be making two circuits for this project, one for the motor and one for the battery. I will be connecting both using a USB type-A cable.

I am using a small 3.7v Lithium-ion battery for this project. I am also using a power bank module which is used for charging in this project. There are 3 USB ports in the module which gives a 5V output. I will be connecting the motor circuit to one of them.

Now, connect the battery to the positive and negative terminals of the module.

I had some space to the side opposite to the space left for the fan. Here, I kept the battery and on top of that, the power bank module was placed. Then I connected the motor to the case using superglue. The switch was attached to the side of the case using some adhesive and insulation tape.

Connect the USB to any 1 of the 3 ports. This will close the circuit.

So, as you can see the machine is working as expected. It can be useful for collecting pencil shavings and bits of paper.

Good luck building!
