Today started off well. Got up at 4:45 and started to do my Wim Hof breathing. Then I got to work on the sensor fushion algorithm. I had breakfast at 7:45am. Around 8:30 am I had a shower. I ended it with 1min of cold water. It felt good. I still believe I have the groin cycst. The cold shower helped a bit.

After which I had a meeting at 9:30 am and again go to work on the sensor algorithm. My goal is to get this working asap.

In the afternoon I went for a run. I am averaging a little less than 10km/hr. I felt good after a run. I ame home and had dates and nuts as I was tired and needed some energy food. After which I had lunch. Salmon with butternut squash, yoghurt and cucumber.

In the afternoon around 3:00pm my eyes started to hurt. Which eventually led to an headache. From 4 to 8 i have not been too productive. Took a tylenol to ease the pain. After dinner, which I had around 9:00pm I felt a whole lot better.

I am studying a bit of Kalman filtering and Complementary filter too. Will need to try and test different sensor sampling rate, 2g/4g/8g readings and other factors to get a decent reading from the sensors. Regarding the Kalman filter, I did input my data to the algorithm, but the output does not seem to make a whole lot of sense. This is why I need to study the algorithm better.

Here is the output of the Kalman filter with my sensor readings. Looks more like a heart rate graph.. The sensor readings by itself as shown above makes sense. But in the fusion algorithm somehow things are not working as expected.
