Most PCs have conventional 9pin RS232 serial interfaces. If we use this -
without any IrDA infrared communication - and use simple optocoupler-isolation,
Iīm not sure if the design would be safe enough to meet safety norms.
It would be possible to make a design that exists of two modules. One IrDA
module that can be connected to the PC and one EEG module. People who own
Notebooks with built-in IrDA donīt have to build the IrDA module.
Itīs possible to buy the IrDA module for a normal PC in a computer store, it
costs approx. 20-30$.
What do you think ? Would it be too expensive to spend 30$ on an IrDA module ?
How many people have a notebook computer with IrDA in this group ?
