A custom lightsaber is a toy that can be played with safely and for a long time if you follow the instructions and precautions carefully. Please check this page and use it safely and correctly.

Precautions for use

  • Do not attach a blade of a different size, such as 7/8 inch, to a saver that is compatible with 1 inch blades. There is a risk of misalignment of the connector contact position and failure.
  • Do not use towards people or animals.
  • Always charge lithium-ion batteries using a dedicated charger.
  • Please refrain from using (starting) while charging.
  • In the case of Inhild LED (RGB-X), the installed illumination type LED is very powerful. Please be careful not to expose the LED light directly to your eyes. It may have a negative effect on your eyesight.
  • When installing batteries, be careful of the positive and negative polarity of the batteries. If the polarity is incorrect, a reverse current will flow and the board may be damaged.
  • Continuous use time for the Neopixel model is approximately 30 minutes. After that, it will need charging. Please note that this product is not suitable for long-term use.
  • Do not let the neopixel pin in the blade attachment port on the saver side touch anything metal other than the blade. A short circuit may occur and cause a malfunction.
  • Please operate the circuit board so that it does not come into contact with conductive objects such as metal or moisture.
  • When using it, be sure to attach the grip parts. If you swing only the chassis, it may put stress on the chassis and cause damage.
  • When installing the blade, please do not apply too much force and do so slowly. If you attach it too forcefully, the connector or LED may be damaged.

Configuration notes

  • When changing Proffieboard settings, please limit the volume status (#define VOLUME) to 1800. If the output exceeds the upper limit, the speaker may malfunction.
  • We cannot guarantee any problems caused by changing the settings or problems caused by changing the settings, so please deal with them at your own risk.
