Teens aged 13–18 of all experience levels can participate in Wisp! Guided projects are available.
Q: Does My Design Have to Be Original?
Yes — everything you submit should be your own original work.
Q: How Do I Prove My Weight?
For 3D prints, submit a slicer screenshot or a photo on a scale. For PCBs and other hardware, photo on a scale showing the weight.
