Guest guest Posted May 3, 2011 Report Share Posted May 3, 2011 I am offering two EEG biofeedback devices for sale used. They are both QDS amplifiers.1) Focus (2 channel) power source is a 9 volt battery. Specs256 samples/sec16 bit processorBaud rate 57600Bandwidth 0.01 to 60 hertz4.75 X 1.75 X 3.2 inches in sizeDesigned for BioexplorerCost new = $700My Price = $350With Bioexplorer Dongle = $650 (+shipping)=================================================2) QDS Excalibur (4 Channel) uses 6 AA batteries Specs256 samples/sec16 bit per channelBandwidth 0.01 to 60 HzJumpers and spiders included to connect channels and block off unused channels.Both amps require a com port or a USB-Serial port converter (about $30)Cost new $2200My Price - $1100With Bioexplorer dongle $1400I also have assorted electrodes, photostim glasses, QDS photo-translator that turns audio feed into LED flashes. I don't know how to price this because it only works with an extra internal or external sound card and takes some jiggering which I am not willing or equipped to do. If interested make an offer.
