The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
okay cool that makes sense. right i think ive done everything. put some power thought the self resonant driverboard everything seems to be in order so far! very exciting. i have a question about the testing and tuning. how different is the mini brute testing to the DRSSTC II? i only have the book with building plans for this is it very different? im also using an ardiuno for the controller which im hoping will do the job.
cheersfor the replies, just want to get the thing running now!
One question in the testing of the Mini Brute. I constructed the 555 circuit as described in the Mini Brute book. I also completed the Advance Modulator Board. If I understand this correctly the Advance Modulator Board will operate the output @ 100hz. What size scope will work for this purpose??

The Advanced Mod board is a low frequency modulator which will operate around 50-300Hz. Any low cost oscilloscope will work for this application.
Has anyone had a problem with noise in the square wave from the output on the Resonant Board. I check Pin one on U1:A and I have a nice square wave on the output from pin 2 U1:A and I have a square wave but, on the top on the top of every 4-5 square wave i am getting a half wave hump. I assumed that this is not normal and this could be the noise that I am seeing on the output. The Resonant board is grounded... Has anyone had any problems like this ???
I have located the noise it is caused when I put a 10uf cap in series with T10 or T102. What type of cap should be used here?? (tantalum, film??? When testing the phasing on the transformers how should the scope be set up (invert channel 2 and ADD)???. I think no... but, not sure.
Right I bought the other book, made sence to get it. Have a quick question, when I apply power to the self resonant board I get a current fb light turn on on the display board should I be worried?
Also has anyone used an arduino as an external modulator?
