10 Builds

High voltage, electromagnetic forces, and physics experiments that belong in a government lab but somehow live in your garage. Expect sparks, levitation, and at least one alarmed neighbor.

Tesla coils that play music. Electromagnetic can crushers. Rail guns. Levitating objects. Vacuum chambers. Cloud chambers that reveal invisible radiation. This is the category where you stop building tools and start building demonstrations of raw physical forces.

Most of these builds involve high voltage, strong magnetic fields, or vacuum systems. They demand respect and understanding of the physics involved. But the payoff is seeing forces that are normally invisible made dramatically, unmistakably visible.

Suggested Build Order

Start with kitchen physics, progress toward electromagnetic weapons:

  1. #042 — Grape Plasma — One-star effort. Microwave + grape = plasma.
  2. #041 — Cloud Chamber — See radiation tracks. Simple sealed chamber.
  3. #034 — Jacob's Ladder — Classic high-voltage arc. Basic circuit.
  4. #039 — Vacuum Chamber — Vessel construction with vacuum pump.
  5. #037 — Coil Gun — Electromagnet switching and projectile acceleration.
  6. #033 — Musical Tesla Coil — Resonant circuits + audio modulation.
  7. #035 — Electromagnetic Can Crusher — High-current pulse generation.
  8. #038 — Electromagnetic Levitator — Feedback control loops for levitation.
  9. #036 — Rail Gun — Extreme current delivery and magnetic field control.
  10. #040 — Mass Spectrometer — The ultimate: vacuum + ions + magnets + detection.
