Hey, Are you an programming and electronics enthusiast and care about you fitness activities on top of that too? There are a lots of awesome fitness bands and trackers available in the market for that purpose but what about fulfilling the enthusiasm of the programmer inside you? Today, we got a product for both the above purposes.

About the Product

The product that we are going to talk about today is known as OpenHAK which stands for OpenSource Health Activity Kit. It can serve as your fitness tracker by tracking your steps, your heart rate and the body temperature out of the box.It offers not only that but many more customisation too. As this product is open-source anyone from any corner of the world can modify or use it’s hardware or even software to create better and more equipped versions of their own. It comes with a free app which connects to it via Bluetooth and records as well as displays all the data you need from it. The developers say, “You can share, graph, combine, delete, process, visualize, merge, bin, count, aggregate, average your data” and actually the possibilities are even more. It has got a space for fitting watch bands right on the PCB itself that means you can fit any 18 mm watch band to it.

Talking about the technical specifications : it includes an Bosh BMI160 for step counting and a Maxim MAX30101 for heart rate measurement. They also include that out of the box, the OpenHAK works, and connects to your phone/tablet. Once connected, the OpenHAK will go through a cycle of deep sleep for 10 minutes, then waking up for 30 seconds to take your pulse and send all of its new data to your phone/tablet. This includes a time stamp, steps, heart rate, and battery level. There’s room for three more data points that are not used which you can use for all kinds of stuff. Other sensor readings from something you’ve hacked into the OpenHAK, for example. Their current prototype send the temperature taken from the MAX sensor, which is right on your wrist. They have also provided some GPIOs and power pins that you can use for connecting external components of your own.

From my side, it’s really an mind boggling product. As I love wearing fitness bands and currently using Mi Band 3 as my daily driver for the purpose. I tried doing some types of customization to it but there’s not much room to play with the max you could do is changing the firmware for applying different themes. i also tried to do kinda Bluetooth automation with it but failed most of the time. So considering the point of customizability it’ll really take the win but it is very much crude to beat other bands though.

Thanks a lot for reading the article.

  1. *There are certainly a lot of details like that to take into consideration. That is a great point to bring up. I offer the thoughts above as general inspiration but clearly there are questions like the one you bring up where the most important thing will be working in honest good faith. I don?t know if best practices have emerged around things like that, but I am sure that your job is clearly identified as a fair game. Both boys and girls feel the impact of just a moment?s pleasure, for the rest of their lives.

  2. For centuries people have been using Proteins for their beneficial health properties. Whey is derived from milk and is the by product of cheese production. Today it has found its place in nutrition as it offers optimal health and enables good fat burning. The modern high fat, high calorie food intake that is low in nutrients is one of the major causes of obesity. Protein provides the opposite. It is a low fat, low calorie and low carbohydrate food that is placed low on the glycemic index (GI) Scale. Replacing high fat and high calorie meals with this protein will melt the fat away because the body has to work hard to process protein. Any fast fat burning diet has to include Protein. Why should we eat Protein? When we are looking for fast fat burning foods it is important that we find the elements that will work best for us. We need to control what we eat and what we drink and water is a good way to process waste that is caused by the conversion of fat into energy. Increasing protein is important too as it helps build lean muscles which in turn burn more calories and accelerate the fat burning process. Our body uses protein as its building block and uses it to create lean muscle. One of the best proteins that can be taken is from whey as it provides the most protein without the carbohydrates or fats. This means your body can use it more efficiently in your quest to burn fat.
