AUDIO_DRIVEN_XENON_TUBE_FLASH_CIRCUIT

Published:2009/7/13 11:32:00 Author:May | From:SeekIC

This circuit uses a Xenon flashtube to create a very real lightning effect. It can be driven in one of two ways: by sound input or by straight repeated flashes, depending on where switch 2 is positioned. When producing straight flashes, the rate is determined by pot R7. If the switch is set to be triggered by sound, the sensitivity is determined by the level of the sound driving the transformer TX2 and the setting of pot R10. This circuit uses high voltages (over 4000 V for the trigger), and extreme care should be taken by anyone that builds it. The high-voltage capacitors can hold dangerous voltages for some time (even after the circuit has been unplugged). Strong caution concerning part polarity is highly urged.
