DIY ECG/EKG Electrocardiogram

I needed an ECG but faced long wait times to see a specialist. I decided to build a DIY ECG device using the AD8232 ECG module and an ESP32-S3 dev module with an LCD screen. After some tinkering, I was able to build a device that read ECG data and displayed it on a screen. I also added a feature to detect the frequency of the ECG data and calculate heart rate via the RR interval in realtime on a browser through websocket.

How to use Neo4j recommendation engine in your GatsbyJs static generated site

We have the Ne4j graph database running and the Cypher query ready to get the recommendation for every drink. We will need an Apollo server running in front of it to enable graphQL. GatsbyJs will connect to that graphQL endpoint during the build time to query for the recommended/similar drinks while building each drink’s detail page.
