--Important-- Tesla coils are dangerous devices! Use the utmost care and fore thought in the design and operation of these devices. -Warning- Tesla coils generate high intensity fields, anyone who is dependent on any electrical device to sustain life such as a pacemaker etc, must not come anywhere near an operating coil system! -Warning- The ionization of air at the spark gaps and at the top of the secondary coil produce lethal gases! Ozone, oxides of nitrogen and others are formed by altering the molecular strucures of the gases present in air when they are forced to conduct electricity. A build up of these gases can occur and become a health hazzard. Always operate any coil system with proper ventilation. -Warning- High level broadband noise is generated by the spark gap and output discharge, hearing protection is strongly suggested. --Disclaimer-- The author of TESLAC nor my family can or will be held responsible for the operation or safe use of any coil constructed using this or any other design program, I cannot control the use of your coil! Build and operate Tesla coil systems at your own risk! --The Program-- TESLAC was written by me to be a help/and time saver in the design of coil systems, its output information has been checked against built coils and the answers given in the program are amazingly close to the parameters of coils that are operating. The calculations are based on PROVEN time-tested formulas that have been altered (if needed) to improve accuracy (I.E. better represent the real world). When certain limits are exceeded in the program, it will warn you by a short BEEP, If you enter a or a zero (0) at any input prompt that portion of the program will halt. TESLAC can be used to calculate any part of a coil system, or each section can be utilized to design a complete system, you using the program will develop the best way for the program to serve you. --About the Author-- I've been tinkering with Tesla coils for over 20 years, but have only been seriously persuing it for about 5 years. I currently operate two systems, a small table top system that runs at 700 watts it produces a 19" discharge, it uses a 4.25"dia secondary wound to a length of 13" with # 24 wire and a 2x12" toroid on top, it runs at about 300 khz. The other coil is "dubbed" Pandora and runs at 5KW input it produces a discharge of 7 - 8 feet. Using a 8 1/2" diameter secondary wound to a length of 30" using #18 wire. The terminal is a 6x36" toroid, it runs at 130 khz. The drive transformer is a 8400v potential transformer. The first version of Pandora can be seen of TCBOR's video #30, and in the TCBA news Vol 12 #2 1993 page 9. I also am a active radio amateur (HAM) and hold a Extra class license, callsign WB8JKR. Im active on all bands from 1.8 to 144 Mhz. I've been involved with electronics for some 25 years and my background involves mainly high power RF amplifier design. --NOTE-- This program is distributed as freeware, and copies may be made and distributed as long as this .TXT file is included with the main program, and neither TESLAC.EXE or this README.TXT file have been altered in any way.
