Automatic rotating base for moon w/ battery

==========中文==========

简介:
本模型基于N33 Designs的电动底座二次创作。原作者的作品给了我很多启发, 感谢他的优秀设计。

修改:

1. 增加锂电池供电
   支持1节或2节18650并联
2. 修改LED安装方式
   改为杜邦插拔, 方便拆装
3. 增加磁铁固定月亮
   方便月亮的定位和固定
4. 电机安装座下降0.3mm
   不知何故, 按原始设计打印后(使用拓竹PLA黑色耗材), 齿轮略高, 因此我将电机座下降了0.3mm
5. 增加硅胶脚垫
   防滑, 如果买不到硅胶脚垫可以自行用TPU打印

BOM:

• *锂电池充放电电路板 1pc
  https://detail.tmall.com/item.htm?id=647734829372
  尺寸: 26mm*19mm
  可以使用拓竹套件013咖啡布粉器中的充放电板, 但需要修改模型适配此电路板的尺寸

• *PWM电机调速板 1pc
  https://item.taobao.com/item.htm?id=614549662117
  尺寸: 32mm*32mm

• *拓竹LED套件001或替代品 1pc
  建议使用平替款, 平替款在中心有一个孔, 如果用Kit 001则需要在中心打一个Φ3的孔

• *N20电机 6V 30rpm 1pc
  https://item.taobao.com/item.htm?id=525167243889
  不同转速的电机变速箱尺寸不同, 模型适配的是6V 30rpm的电机, 如果使用其他转速的电机需要修改模型
• 2.54mm杜邦 2PIN 1pc
• *2.54mm加长弯排针 2PIN 1pc
  https://item.taobao.com/item.htm?id=626901934945

电路图:

组装说明:

• PWM电机调速板需拆除接线柱
• PWM电机调速板背后需引出LED供电线(参考电路图)
• 电池正负极片需要修剪至14mm宽
• 考虑到PLA材料不耐高温, 建议先焊接电池正负极片的导线, 然后再将正负极片插入底座
• LED模块背面需粘贴绝缘胶带
• LED排针引线需要用热缩管或绝缘胶带保护
• N20电机变速箱建议加润滑油

==========ENGLISH==========

Introduction:
This model is a remix based on N33 Designs’ automatic rotating base. The original author's works gave me a lot of inspiration, thank him for his excellent design.

Modification:

1. Add lithium battery power supply.
   Supports 1 or 2 batteries in parallel.
2. Modify the LED installation method.
   Changed to DuPont plug-in for easy disassembly and assembly.
3. Add magnets to attach the moon.
   Convenient positioning and firmly attachment of the moon.
4. The motor mounting base is lowered by 0.3mm.
   Somehow, after printing the original design (using Bambu Lab PLA black filament), the gears were slightly taller, so I lowered the motor mounting base by 0.3mm.
5. Add Non-Slip Mat
   Anti-slip, if you can’t find non-slip mats, you can print them with TPU.

BOM:

• *Lithium battery charge circuit board 1pc
  https://detail.tmall.com/item.htm?id=647734829372
  Size: 26mm*19mm
  Alternatively, you can use the charging circuit board in Bambu Kit 013 "BooKoo Coffee Electric WDT", but the model needs to be modified to fit the size of this circuit board.

• *PWM motor speed control board 1pc
  https://item.taobao.com/item.htm?id=614549662117
  Size: 32mm*32mm

• *Bambu LED Kit 001 or alternative 1pc
  It is recommended to use the alternative which has a hole in the center. If you use the Bambu LED Kit 001, you need to drill a Φ3 hole in the center.

• *N20 motor 6V 30rpm 1pc
  https://item.taobao.com/item.htm?id=525167243889
  Motors with different speeds have different gearbox sizes. The model is suitable for 6V 30rpm motors. If you use motors with other speeds, you need to modify the model.
• Dupont Connector 2.54mm Pitch 2P 1pc
• *Male 90 Degree Pin Header 2.54mm Pitch 2P 1pc
  https://item.taobao.com/item.htm?id=626901934945
  You need to use non-standard headers with a long end of 8mm. If you can't find them, you can also use standard headers, but the contact distance is shorter.

• 2.7Ω 1W resistor 1pc
  The original power cord of the LED module has a resistance of about 3Ω, which acts as a current limiter. After the power cord is removed, the current will increase, and the heat generated by the LED will cause the LED base to deform, so a 2.7Ω resistor needs to be connected in series to limit the current.
• 18650 3.7V lithium battery 2pcs
• *18650 battery spring contact plate 2pcs
  https://item.taobao.com/item.htm?id=750378496013
  Size: 18.5mm*16.5mm

• Heat Shrink Tubing
• M2*Φ3*H2.0 threaded heat set inserts 2pcs
• M3*Φ5*H4.0 threaded heat set inserts 1pc
• M2*3 screw 2pcs
• M3*10 flat head screw 1pc
• Φ6*H2.0 magnet N52 6pcs
  Installed on top of base
• Φ6*H3.0 magnet N52 6pcs
  Installed at the bottom of the moon
• *Non-Slip Mat 4pcs
  https://item.taobao.com/item.htm?id=742234863086
  Size: Φ10*H1.0
  You can print them with TPU.

*If you are outside China, aliexpress is worth a try.

Circuit diagram:

Assembly instructions:

• The PWM motor speed control board needs to remove the binding posts.
• The LED power+ needs to be led from the back of the PWM motor speed control board (refer to the circuit diagram).
• The battery spring contact plate needs to be trimmed to 14mm wide.
• Considering that PLA material is not resistant to high temperatures, it is recommended to weld the wires of the battery spring contact plate first, and then insert them into the base.
• Insulating tape needs to be pasted on the back of the LED module.
• LED pin headers need to be protected with heat shrink tubing or insulating tape.
• It is recommended to apply some lube to N20 motor gearbox.
