The Valentine's Day Project: a Visible Heartbeat

Valentine's Day is coming, are you worried about she/he likes you or not? Maybe you want to ask, but here is another way, put the finger into the heartbeat device, the data will show the answer.

The heartbeat of adults is about 70~80 times, well, 60~100 times is normal. When the heart beat frequency is above 100 times in one minute, which means Tachycardia. And when the heart beat frequency is lower than 60 times in one minute, it is called Bradycardia. How could we know our own heartbeat? There are many heartbeat measurement device, and many smart bracelets equipped with this function. As a maker myself, taking advantage of the open source hardware, I made one heartbeat device with two main functions: 1. Put the finger to the heartbeat sensor, once the heartbeat is detected, a red heart will beat in the centre of the device, indicating the heartbeat is detected. 2. The OLED display will show the heartbeat frequency.

Hardware List

5. 8byte RGB Ring

6. Jumper Wires

7. Laser Cutting Parts

1. Design the laser cutting parts We have used the software to design the crust and cut it with the laser cutter.

2. Secure the soleplate and surrounding panels with 502 glue
