Hi everyone,<div><br><div>I&#39;m writing because I had an idea, and I&#39;m trying to move it on. I just want to</div><div>know whether you think it is something worthy, or whether I should give up</div><div>with the idea. I&#39;m close to get the first prototype, and I shoud make an</div>
<div>investment... that&#39;s why I&#39;m trying to figure it out.</div><div><br></div><div>You can follow all my work at this website: <a href="http://www.openelectronicdesigns.com">www.openelectronicdesigns.com</a>.</div>
<div><br></div><div>So, the idea is as follows: I designed a fully portable system, mainly thought</div><div>to be a low power one. It has an LCD screen with backlight, a tactile slider to</div><div>navigate the menus, a microSD card to store data, a Bluetooth module to link</div>
<div>to any computer which supports bluetooth, a piezo buzzer for user notification</div><div>events, a Li-Ion battery which is charged through the computer, and a USB link.</div><div>It also supports the USB suspend mode, so that it also is USB compliant.</div>
<div><br></div><div>The main goal is to offer a digital and portable MODULAR system. What it means</div><div>is that this module does nothing without another digital subsystem plugged in it.</div><div><div>I just designed this device with the most common needs for any portable medical</div>
<div>device, and in this way, the subsystem can be much more simple.</div></div><div><br></div><div>Thus, you could just plug a heart rate monitor subsystem to this module, and it</div><div>would be working as a heart rate monitor. Just plug an EEG module, and it would</div>
<div>be working as an EEG monitor, or data storage, or whatever you want.</div><div><br></div><div>This module provides 4.35V to supply the subsystem, and a UART protocol for</div><div>communication. The subsystem should work at 3.3V, since the UART is working</div>
<div>at such voltage.</div><div><br></div><div>I already had in mind several subsystems. I would do them in order, from the</div><div>easiest to the more difficult one:</div><div><br></div><div>1) A magnetic field headset generator. It would be a headset with coils on it, and</div>
<div>once put it on the head, it would generate several magnetic waveforms. It is</div><div>easy because it is just a programable current source. The main module just should</div><div>send UART commands with the current desired at the coils. In this way, the</div>
<div>magnetic Schumann resonances could be simulated, or applying a single sinusoidal</div><div>waveform (let&#39;s say at 14Hz), you could increase the EEG amplitude at such a</div><div>frequency.</div><div><br></div><div>
2) A heart rate monitor. The performance of this subsystem would be analized to move</div><div>to the EEG subsystem. The thing is the heart rate is quite easy to measure due to</div><div>the high voltage amplitude (well, of course compared with the EEG). Then, in function</div>
<div>of the noise of this acquisition system, I could redesign it or make some</div><div>improvements for the EEG monitor.</div><div><br></div><div>3) An EEG monitor. Needless to say why use it, you are at this list for something ;)</div>
<div><br></div><div><br></div><div>Of course this module could be used for lots of other projects, even if they are not of</div><div>any medical aspect. Just choose a low power microcontroller with UART and working</div><div>
at 3.3V, and you will be able to use this portable module.</div><div><br></div><div>So, what do you think about it? Please, take a look at my website, so that you can get</div><div>a better idea about what exactly it is.</div>
<div><br></div><div>If you would like to start designing your own EEG subsystem for this device, just email</div><div>me to discuss how, I have several ideas in mind.</div><div><br></div><div>Thank you!</div><div><br></div>
