60hz Vs 50hz

[bzorglub]

Hello to all,
I'm new on this forum and fond of Biofeedback, so I intend to order an OpenEEG but before I have one question:
I understand that these devices/soft are provided for US area with a 60hz power, I'm living in France, so power is 220v 50hz, is there any issue praticing with this device and software with another frequency ?

I already read that in a previous thread:
"If you aim at high accuracy it is good idea to not touch anything connected to regular power supply (120V/220V) since it might issue a 60Hz/50Hz hum/distortion to the graphic. If powering the board from laptop it might be good idea to disconnect it from the electric network and use only the laptop battery for power."

OK, Olimex looks Bulgarian based, checking the whois, so looks ok for 50hz :-)

Thanks for your support.

BZ.

Hey bzorglub,

You can use EEG-SMT in any country but the 50 Hz noise from power input should be taken care of separately. Impulse power supplies is one way to do it.
