Motion-activated LED magic wand

thingiverse

This innovative design is meant to create an automatic motion-activated "Harry Potter" style LED wand that illuminates with a bright blue-white light when raised vertically, turning off instantly when lowered. The wand relies on a precision tilt switch and requires approximately $10 worth of parts along with a soldering iron and solder for assembly. For those who prefer a simpler approach, the design can be printed out and used as a costume wand, which looks remarkably good. However, the added feature of an automatic light-up LED is sure to captivate any child who wields it, guaranteed to put a wide smile on their face. Detailed build instructions, including part lists and sources, along with step-by-step photos of the wand's assembly process, can be found here: https://docs.google.com/document/d/14bZ-IpqVbZkPPZfCg1i2cHG-t4NB6BFCnUCOYWv-gT0 The design has been tested, with the entire printing and assembly process taking under two hours the first time around. With experience, the time required to assemble a single wand has decreased significantly, now taking approximately 20 minutes for each successive build. While glue is not necessary for assembly, 3M Super 77 spray adhesive was used to secure the top halves of the wand together and hold the wires in place. Alternatively, electrical tape can be employed to keep the LED secure and the top halves connected if glue is not an option. Anyone who decides to build this design is encouraged to share their expertise on improving the battery assembly or wand design, as feedback is always welcome and valued for future iterations of the project.
