    As Peter Balch explains, COVID-19 can sometimes give rise to cardiac complications. So, while not presented as an actual piece of medical equipment, he decided to construct an ECG (electrocardiogram) unit using an Arduino Nano for control along with an integrated 320×240 SPI display.

    His battery-operated device features an AD8232 heart rate monitor module to acquire data from the human subject. This is connected to its wearer via electrode pads, or to a fake pulse generated by the Arduino for testing. The system allows you to view one or two heartbeats on its screen in a large format as well as many heartbeats in a smaller setup. A Poincaré display mode is also available, which plots the time between heartbeats.

    Code, additional information, and future plans can be found in Balch’s project write-up.

    Star Trek tricorder-style heart rate monitor

    A heart rate monitor can be an important tool for tracking fitness and exertion levels, but what if you want something a bit more interesting style-wise? For a novel idea, be sure to check out the project shown below from “Taste The Code.”

    In it, Blagojce Kolicoski turns a handle used for launching rotating toys into something reminiscent of a tricorder from Star Trek.

    The build stuffs an Arduino, a pulse sensor, and a tiny OLED display into the handle, which conveniently already had accommodations for three AA batteries. This, along with the monitor’s I2C connection, meant that wiring everything up was quite simple.
