5pcs ADMP401 MEMS Omnidirectional Microphone Breakout Module Board

【20KVDC】20KV 20000V High Voltage Pressure Generator Igniter Step Up Boost Module Coil Transformer Pulse Ignition 1.5A DC 3.6-6V 【Compatible】Double high voltage cable can ignite cigarette and paper, a single high voltage cables can provide power to a metal body, and no sound support. 【Design compact】The module can be used as high-school scientific experiments, electronic devices, negative-ion generator, high-voltage source, to use when small science. 【Easy operation】Over power: Single 18650 or idle mobile phone batteries (the protective plate to remove the planned capacity of 2000mAh or more). 【Specification】Power must be adjusted to a suitable distance to the high-voltage output line , battery capacity is proportional to the distance and the use of the high-pressure arc ( not a voltage as high as possible , you must provide enough current ) . Experimental test of the arc distance from short to long , Do not exceed the maximum arc distance electricity, energy can not be released due to high pressure , can easily damage the module.
