[Openeeg-list] Open eeg problems

[zach g. <zac...@ho...>]

I bought my eeg boards from olimax preassembled and instead of using a serial cable I decided to use a arduino mini usb adapter to connect and power the board off of usb and through a laptop running off of battery power to keep it isolated . I believe I have everything assembled correctly, I installed a wire in place of D103 and the 7805. I also prgrammed the board using a usbtiny instead of making the sp12 prgramming cable. my problem is when I go to run electric guru with the setting for the mod eeg I see nothing, and this is with no electrodes hooked up because I have yet to built them, I'm just testing it out. But when i run it through with Braainmaster it works but I get data displayed but it cuts out about every 5 seconds. Does anyone know what could be causing this, is it because of the usb adapter, or could something else be wrong?

any help is appreciated. Thanks, 
Zach
