I will definitely give it a try, and hope that I don't fry my laptop and/or EEG, as a result of some misconnection. Not having to mess around with batteries will be a real help. Rechargeable battery technology just isn't where it needs to be, yet, and 'normal' batteries are too expensive to keep buying very often. As you stated, this information will undoubtedly be of interest to many others who frequent this website, so I'm sure that you have helped several of us.

The unpatched > ModularEEG needs at least 7.5V for operation,' how do I do that? Unsolder IC107 (the 7805 voltage regulator) and solder a piece of wire from the left to the right pad of the 7805 footprint on the pcb.

This connects IN with OUT and bypasses the regulator. Additionally you have to unsolder or simply short D103. This is a diode that protects the modularEEG from reversed batteries. However it takes 0.7V away and that is not acceptable when we have only 5V. Solder in D104 (if you have no spare one, you can use the D103 you have desolderd). This now is the new reverse polarity protection in shunt mode.

Instead of blocking as D103 did, this one protects by the crowbar method: A reversed power supply is shorted to GND. Not so nice but better than no protection at all.

You can omit D104 if you are very sure that the power polarity is always right. This is a valid assumption on USB cables. Dolby pcee drivers x64 download.

When using the LT1168 all you need for a bullet proof ESD protection is a series carbon composition (bulk not carbon or metal film) resistor for each electrode input - as described in the datasheet. Also you have to down adjust the DRL output voltage level to center the common mode input range.
