Benefits of negative ions supposedly include
• freshen and purify the air
• help lift mood
• alleviate depression including winter depression(SAD)
• eliminate most tiny particles suspended in the air (indoors)
- HIGH VOLTAGES present in both devices is high enough to induce a bad case of temporary Tourettes. ie twitching/profanity.
- Be aware of the hazards when working with loose CARBON FIBRE filaments if using this option for high voltage grid instead of pins.
Step 1: Components and Design
- soldering iron and solder.
- screwdrivers, flat and star
- cordless drill.
- hot melt glue gun.
- wire wrapper.
5v to reduce current consumption and noise.
The half wave version uses fewer components and less current, the smaller size is also trickier to build.
In both versions the negative band on the diode must point towards the ac voltage input.
If you follow the green arrows on the component diagrams, you will first encounter the negative side on the diode first, indicated by the white band.
