I’d like to share the current progress while still debugging! ! I accidentally saw the magnetic levitation lamp and fell in love with it, so I wanted to get one. In addition, the offline voice remote control of Qi Ying Tai Lun that I made in the last training camp was so easy to use, so I wanted to make another one. I just wanted to combine the two to create an ornament that is both ornamental, practical and space-saving. It is currently suspended, and the parts will be integrated onto a PCB later.
Complete view of parts!

Production process! Apply solder paste
Paste components
Teppanyaki welding chip components, only the power supply and wireless power supply parts are welded here. The purpose is to test whether each part is working properly in a step-by-step manner, so as to facilitate troubleshooting later!
Welding magnetic levitation control part
Install the coil and magnet!
Test whether the XYZ Hall is working properly!
Test wireless power supply! In the early stage, a relatively small triode was used and the heat was serious. Later, a high-power triode was used for 5V power supply (previously, the light was brighter with a 12V power supply, but it would decay if it could not be used for a long time) and after adding a heat sink, it worked better!
Welding LEDs on both ends of the coil makes it easy to observe the direction of the magnetic field and whether it has entered the high-frequency adjustment state.
What it looks like after welding is completed. A relatively large heat sink was used to protect the chip during debugging! The offline voice part works normally, but the magnetic levitation part is more difficult!
The capacity is limited and has been overturned. Based on the existing experience, each part will be separated for debugging. The lifting magnet will be enlarged, the high-current driver will be replaced, and the precision potentiometer will be replaced (the adjustment amount of the potentiometer this time is too large) to modify the Hall feedback. circuit.
The next step is to dismantle the magnetic levitation part. The factory picked up an iron wire with a diameter of about 4mm and simply cut, removed rust, and spray-painted it to hang the moon lamp with magnetic suction.
I bought an infrared remote control RGB lamp from Laowujia for 9 cents before.
Soldering RGB lights
Scrap iron wire
Remove the components of the magnetic levitation part and install the speakers, wireless power supply and magnetic suspension bracket (using the screw holes of the magnetic levitation)
Hang the lamp and adjust the hanging height so that the moon lamp receives the alternating magnetic field
The height of the 3D printed feet is based on the thickness of the speakers and RGB mounting to the bottom.
Because the RGB lights and speakers are installed inside, the installation method of the feet has been changed.
Effect after installation
Cut new chopsticks once to surround the shell
Lamp inner structure
The finished effect! !
Some of the magnetic levitation components are being supplemented and will be shared after they are successfully produced! ! !
The magnet floats should be stacked like this to facilitate later debugging!
Share the current progress first, and then upload the information after sorting it out! ! Thanks! !
