Jacobís Ladder becomes Kid-Safe!
posted November 3 2010 10:00.45 by Giorgos Lazaridis

A Jacobís Ladder is surely an impressive piece, yet somehow dangerous due to the high voltages. Paul wanted to make a kid-safe Jacobís Ladder replica. He came across a video that demonstrated a sequencer with Electroluminescent wires connected, and that flashed him the idea. He got the EL sequencer from SparkFun, got his Electroluminescent wires and start building the EL Ladder.

In his website you will find the building worklog for this project. A PIR sensor senses human approximation and starts the sparking. The sparks are not generated by high voltage arcs, but from the EL wires! Because there is no sound, he added a speaker, an Arduino and the WaveShield to produce the "arc sound". He put the EL wires inside PEX transparent tubes, and there it is, the EL Ladder from Paul.

    • Instead of looking to the project itself, better look at the idea. You may use it in the future
