Featuring an optional fan on the full-wave model. 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)CAUTIONHIGH VOLTAGESpresent in both devices is high enough to induce a bad case of temporary Tourettes. 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 DesignShow All ItemsTools required: soldering iron and solder. screwdrivers, flat and star hot melt glue gun. The full wave rectified version has better performance but is a bit noisier if using the optional fan. The fan is a 60mm x 60mm CPU 12 brushless fan which I'm driving at

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.honeywell air purifier model hfd-120-tgt 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.« infinity air purifier gapa reviewsPreviousNext »View All Steps Downloadsilent ionic air purifier & ioniser xj-1000Compare 2016 new arrival luggage air purifier, shoe cabenit/toilet/wardrobe air cleaner to remove odor and kill virus Meizhou Huafu Trading Co., Ltd.
