DIY MINI TESLA COIL KIT WIRELESS TRANSMISSION TEACHING IN SOUTH AFRICA

Features: The use of specially designed PCB circuit board. Electrical characteristics are very good, strong performance With better cooling effect of thermal grease. Use high power transistor, product safety and reliability without electric shock hazard PCB size: 85 x 54mm Installation of video connection, the actual installation of only 3~5 minutes: (http://v.youku.com/v_show/id_XMTYzMTcwMjc0NA==.html?from=s7.8-1.2& x) Note: Pay attention to protect the secondary coil during installation, the secondary coil for enameled wire is very fine, so don't hurt or broken wire General secondary coil is the final installation of the power detection after the successful use of glue to fix it on the PCB board. Primary coil to one end of the soldering on the right side of the circuit board "L1" soldering plate and counter clockwise to the other end of the two lap welded to the left "L1" pads, attention is counter clockwise rather than clockwise, if the direction is  reverse, the machine will not work. Unauthorized modification of power interface, if the polarity reversed, it will burn out the triode, remember. Package includes: 1 x PCB 1 x Switch 4 x Screws 1 x Heat sink 1 x Triode 1 x Screw to fi x triode 1 x Resistance 1 x Capacity 1 x Diode 1 x Primary coil 1 x Secondary coil Test pictures, for reference only!
