June 30 - Created the main design and ideas

Spent a few hours researching about ECG and heart and pulse, I do have PSVT so I had a thought in mind to create a portable ecg machine, instead of going to hospital everytime. I'll soon have my treatment but there are many people who might get helped by this tool. I tried to look up for what parts to include too. Time Spent - 1.75 Hr

July 1 - Gathered all the components that I need to use and tried to make it as cheap as possible

completed my cart and added all necessary components I tried to find the best yet cheap versions. Took care of all the dimensions and tried to make it compact. Time spent - 2 Hr

July 2 - Completed the 3D case

Started working on the 3D, it was a bit fun after I have finished my first 3D model, so I knew what to do. Still some silly mistakes led me to spent more time that needed but I'm happy that I completed the full case in one go!!! It has spots for the tp4056 and esp32 and the AD8323 slot too, made place for fitting the back plate and added some fillet to make it look cool, the tricky part was related to the display getting fit in there. But then I just made it a complete cut Time Spent - 6Hr

July 3 - Completed the firmware, Readme and Final BOM

started to do some reasearch on how exactly the ecg sensor work and then took help from AI and then created a basic firmware, ( I'll definetely update this later). finalised the final BOM, created the readme Time Spent - 1.5 hr
