Thank you DAB and Victor for your comments on my previous blog post.  This weekend I focused on further processing the electric signals associated to eye movements, which so far I was able to measure using electrodes placed on forehead, amplify, and bring to a window comparator made out of the two op-amps inside the PSoC4 chip.   The first step, I replaced the debouncers blocks that I used for low-pass filtering with glitch filter blocks.  The glitch filter blocks provide me a b ...
This was a “bumpy” weekend; it started quite good: I built an active Butterworth second order low pass filter using one of the opamps inside PsoC4.  I put together all external components and configured the PsoC opamp to route the output off-chip so I could probe it with the oscilloscope.  I then swept the input frequency (connected to a sinusoidal generator) and everything worked so good.  The cut-off frequency was just as calculated, around 50Hz.   Then the pro ...
First I want to thank all of you who commented on my last week update; DAB, good suggestion - I researched some commercial head sensors and what they are used for, and it looks like a lot of research groups are looking into processing brain waves or various applications.  Paul, thank you for your comment – yes, I can measure the movement of eyes and I am showing some signals below.  Thank you vsluiter for your comments – yes, facial muscles are driven by electrical signals ...
Here I am with my third update on my brainwaves based appliance controller project.  Things started to be harder and harder: after getting enough familiar with PSoC Creator and building a few small applications (that was fun!) I felt that I need to start looking into how I will measure brain waves. This is probably the most difficult part of my project, so I spent a lot of time reading and then I built my first set of sensors as shown in the figure below. These are called passive sensors ...
I spent most of the time this weekend trying to get familiar with PSoC evaluation kit and PSoC Creator software.  I started a little bumpy with the installation, which did not behave at all at the beginning until I figured out that it was a conflict with a previous version already installed on my computer.  I then uninstalled all versions and start over and this time everything worked just fine.   Next I went through the design examples for this kit and I found them very benefici ...
So here I am writing my first blog on Smarter Life Challenge. Let me start with how I got here – it was just the chance of noticing the word “Challenge” in the subject of an email that I was about to delete together with many other emails that make it to my mail box every day.    I opened that email and I read what it was about – a challenge and I thought “yes” I like challenges let me find out more.   Then I saw where it said that compet ...
