I launched a prototype of my first-generation contactless heart rate (fatigue) monitoring device on Product Hunt and open-sourced all the code and PCB design. I'm not looking to sell the prototype, as it still has many flaws. I hope launching this project will get more attention for its progress. I've now hired a new designer and am working with my partners to redesign the circuitry to make it lighter, more accurate, and even more aesthetically pleasing. It will look something like this, generated by AI. Of course, our designers will definitely create something much more refined and beautiful than this.
If you're interested in my project, feel free to follow my blog and website; I'll provide detailed updates on my progress, and you can see my work environment (and my ridiculously dirty workbench) in full detail. Latest developments regarding Easing-Point
Easing-Point A contactless heart rate monitor for your desk. Our first prototype has already been built and released as fully open-source. We are now developing the next stage of the product, focusing on a more minimal and forward-thinking form factor, vertically defined usage scenarios, and improved algorithms for more accurate heart rate and breathing detection.
About three months ago, I built a contactless heart rate monitor and posted it on Reddit. I even mailed it to a helpful Reddit user for testing. One of the reasons I created this device was because I'm allergic to Apple Watch bands, which led me to consider making a contactless heart rate monitor. I chose a millimeter-wave radar and had a circuit engineer friend design the circuit. I was responsible for burning the open-source code into the chip. This device can display basic heart rate and respiration, but its drawbacks are also obvious: it can only display a maximum heart rate of 100 and is easily affected by interference a common problem with millimeter-wave radar. Now I've completely open-sourced it, including detailed PCB design, 3D printed models, code, and sensor data, so anyone should be able to easily replicate it.
