Finished up the modulator board, just need to wire up the switches, which has kinda confused atm. I am having a hard time telling where the 10k ohm resistor goes and the 1meg ohm resistor goes.
Here are some pics. Its not very pretty but it should work. My dremel ate part of the board on the top left hand corner.

That's funny... I had a 'LABTECH' brand oscilloscope that looked exactly the same, and I believe Marko has a 'HUNG CHANG' oscilloscope, also exactly the same... which one is the real deal? =P

Two Words...... It's Alive!
My very first Coil is finally up and running, Well sort of. I am still unable to reproduce Daniel's 4' Arcs. Later this week I am going to fine tune it and see if that makes a huge difference.
Special Thanks to Wirenut for hours of troubleshooting and Daniel for the wonderful book! without the support from this community my coil would not be here today!

mh, did you say "it blew" at the end of the video? oh man, i recognise my first attempts to build a drsstc. man was that a huge amount of dead igbts and other stuff. but great work and keep on it, its really worth it. try tuning it for best sparklenght without turning the on time too high (i could hear that on the end of the video. you turned up the on time until it blew) my drsstcs are working with on times around 80 to 150µS . everything above that i stress to the igbts and other parts. you will soon find a point where the sparklenght stays the same, even if you turn up the on time, the sparks wont grow.
