Simple Room Ionizer Circuit
One device that helps purify the air you breathe inside, is a room ionizer. It produces ions which are little electrical particles. These ions stick to airborne particles such as smoke, dust and other unwanted substances. The ionizer uses a special electrical trick to create these ions. Similar for applying intense pressure to one side […]
Simple DC Over Voltage Protector Circuit
