would stuffing the secondary with caps like in steve's qcw tesla gun improve mini coil performance? will a batch of boards be sold?
Probably not by much. Steve's QCW is special in that it has an exceedingly low topload voltage, meaning the secondary MMC is feasible and the secondary does not flash over.

I'll buy a board off you from your eBay, nothing like helping someone out with a project...I got a s all coil, 3.5 x 12 at 150khz, let's see what it can do!!

Killa-X pointed out to me it would be nice to have a full list of materials.
This one is nearly complete (when combined with the list on my blog):
1 UCC37321 1 UCC37322 1 74HC14 1 74HC74 3 16V electrolytics, I think 8mm spacing, preferably 1000uF 10 1uF ceramics 1 100 nF capacitor 1 330 pF capacitor 1 100k resistor 1 10k resistor 1 600ohm resistor 1 200ohm resistor 2 6.8ohm resistor 2 1N4148 diodes 2 MUR460 diodes (or some other 4A axial-package rectifier of at least 250V) 1 7815 regulator 1 7805 regulator 1 IF-D95 optical receiver 1 PJ-037B power jack (from Digikey)
It'll need a 19V wall adapter (such as a laptop adapter) to run. You'll also need to throw together an optocoupled interrupter of some sort (555/Arduino/whatever), but that's not terribly hard. Note that at this point, the project isn't really production-ready, so if you buy a board, be ready to do some troubleshooting on your own. Kramnik and I will gladly help, but please do post your questions here (as opposed to PM's/e-mails) for all to see.
Also, Eagle is essential right now for assembly; the schematic really helps when putting things together/finding component values. There's a raw capture of the board attached for those who don't use Eagle.

I like this i'm planning to buy a couple at the beginning of this next month been wanting to play around with a DR and get the hang of things before i build something more complicated. This seems just what i need thanks alot.

Could you ship a board to Sweden? If so I would be interested in buying one :)
The project looks great, I like it when things are kept as simple as possible but still are able to perform.
You should PM Kramnik about that, since he's the one doing the shipping right now. And thanks! This board was originally designed to be easy-to-etch, hence its minimalism.
