I hears about your project from Marlieke. Well done that you actually finished the hardware. I have the OpenEeg boards aswell, however I need to spend more time (and money) finishing the project. Could you demonstrate your setup please?
Hi Jasper. Thanks! :)Sure i could demonstrate it. Will you be at the donders sometime in a week or so?
Hi Stephen, great, thanks. During the week i'm usually not in Nijmegen (during daytime), although I'm regularly in Nijmegen on tuesday evenings, maybe we could meet around 18.00 at the donders. Please text me on my mobile 06 five five five two three zero six four, so I can contact you.The 5V voltage regulator requires minimal 7V input voltage to create a stable 5V output for the circuits. I recommend to use 6xAA batteries because some circuits may malfunction or disturb the eeg when the battery voltage is less than 7V.
Ill do that!I'm bypassing the voltage regulator, so its getting a nice 4*1.25 (rechargeable batt.) = 5 volts directly :-)
On the other hand, even when the battery voltage is slightly lower than 5V, the dcdc converter will output a decent 5V.
