attention : if you wait charging longer then it will will produce more output voltage and current flow
this circuit need a charge like a coil gun normally...... how to charge it : press the switch(don' press the button) after that press the button until the relay is open and wait to charge af ter for a few second then press again the switch (not button) to release high power shoot. ......... caution : it is using timer to produce high powered shoot and can produce negative power or positive power ( when it reach number 8 and 9 it will produce negative power and number 1 until 7 to produce positive power........... that's all have fun with my project
