Build an Ioniser for under $10 #Making #Electronics

Amaldev on The Tech Blog writes about building an air ionizer, the same effect some devices use to move and ionise air.

This is a project which I wanted to do around 2 years back but never got around to building it. It’s nothing too fancy or super high tech. Anyone with some DIY capabilities should be able to pull this off without breaking a sweat.

I have open-sourced the entire design, Bill of materials and you should be to order the parts and build one for yourselves in under $10. You can download the hardware files here. Check out the device in action on Instagram here.

What is an ioniser?

An air ioniser (or negative ion generator or Chizhevsky’s chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions, are particles with one or more extra electrons, conferring a net negative charge to the particle.

See how this is built using a Cockcroft–Walton multiplier with some inexpensive electrical components in the blog post here.

And the voltage generation principle is explained in the video below.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
