I Built a Mesmerizing Sand Drawing Machine (Super Satisfying DIY!)

Hey guys, I built this super satisfying little gadget that spins draw patterns on sand and then wipes them clean. It's actually pretty easy to make if you have a 3D printer. I designed the entire thing myself in Fusion 360. So, let's go ahead and print all the components on my 3D printer. [music] All right, all the parts came out perfectly. I went with black, white, and gray color scheme to give it a clean, [music] minimal look. Now, let's talk about the electronics we'll need for this project. First, we need a microcontroller. I'm using this ESP32C6 from Waveshere. Compact, powerful, and perfect for a project like this. Next, there is this N20 motor with an integrated motor driver, which makes it super easy to control. Then, we have got a barrel jack for power input. And [music] finally, an ARGB LED strip for lighting. Optional, but it adds a really nice touch. That's all we need for the electronics. So, let's move on to the [music] assembly. First, detach the integrated driver from the motor. Once that done, solder a pair of wire to the motor. We'll reconnect the driver later. Now place the motor inside the main enclosure and screw it just like I'm showing in the video. Take the ARGB LED strip and install it inside the enclosure about 10 mm below the top edge. Perfect. That's done. Now it's time to reconnect the motor driver to the motor wires. Then grab the microcontroller and solder a pair of wire to the 5V and [music] ground pin. After that, solder the LED wire to pin zero and motor control wire to pin one. Finally, take the power input jack and solder all the positive wires together and all the negative wire together. This gives us a clean shade power input for the whole system. All right, the electronics are all set. Now, let's install the power socket in its [music] place and we are ready to move on to the code.
