Using the MiniPOV 4 Kit is a breeze. First, follow the detailed tutorial to solder about 30 components onto the custom PCB. You'll need a soldering iron, solder, diagonal cutters, and wire strippers. Start with the easier parts and work your way up to the more challenging ones. This process may take about 1 - 2 hours based on your soldering experience. Once your kit is assembled, insert three AAA batteries (not included). Wave the kit around, and you'll see light trails. You can also use a camera with a medium - long exposure to capture beautiful light paintings. To upload your custom designs, design 8 - pixel tall images in any drawing program, import them into our software, and connect the kit to your Windows or Mac computer's USB port. As for Linux support, it's still in testing. When it comes to maintenance, keep the kit dry and away from extreme temperatures. If you're not using it for a long time, remove the batteries to prevent damage. If you encounter any issues, refer back to our detailed tutorial with full - color images.
