Hey Rhys...If you built the pulse generator correctly... then it should be creating pulses... the eye can detect up to about 50 Hz light pulses ( altho some can see flickering at 72 Hz...) an option is to attach a speaker to a low voltage output ( about 3-40 volts depending on speaker size... but remember the speaker has on avg. an 8 ohm resistance Ive seen some as low as 4 ohms) this should be good to about 18-20 KHz or so ( if your hearing is good to excellent)...
As far as measuring hi voltages with a standard meter, this takes some engineering... (or purchasing a hi volt meter lead) add an additional 100 meg resistor to the lead and multiply the voltage on the meter by approximately 100... ( this works for MY meter... not a gaurintee that it works far all meters... depends on what value of resistor is incorporated in the meter originally).
BTW... from reading the thread of your project, seems like you should have gone towards a laser flash tube type of design... Check out SAMS LASER SITE for mega amounts of info on schematic, info, and everything you want to know about flash tubes, diodes, what ever ... the site is FULL of all sorts of photo/optic/electronic info...

I've built my DC pulse generator. I have a nice green LED coming off it. My big question now is, how do I know if it is a pulsed or constant signal? I don't have an oscilloscope and only a very basic meter. Similarly, how do I measure high voltages when my meter only reaches 500v?_______________________________________________Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
