HeartyPatch – Open source ECG patch with Wifi

Electronics News Updates / By Ibrar Ayyub

HeartyPatch is a completely open source, single-lead, ECG-HR wearable patch with HRV (Heart Rate Variability) analysis. It is based on the popular ESP32 system-on-a-chip. By using low-cost, highly-integrated components, we are able to keep the BOM’s cost low, while the simplicity of the circuit design means future expansion will be easier. HeartyPatch can be used

BUILD A PLOTTER USING SCRAP DVD DRIVES

Arduino News / By Ibrar Ayyub

Building your own CNC machine can present a series of varied challenges. There are the software considerations, but also the mechanical side of things – motors, shafts, screws and slides all need to be addressed in a working design. Of course, you can always outsource some of the work – and that’s precisely what [Daniele Tartaglia]

To Build the World’s Smallest Atomic Clock, Trap a Nitrogen Atom in a Carbon Cage

Electronics News Updates / By Ibrar Ayyub

For Fridtjof Nansen, 13 April 1895 started well. Six days earlier, the Norwegian explorer had set a new record for the closest approach to the North Pole, and now he was moving quickly over unbroken sea ice toward Cape Fligely and home. But then came a sickening realization: In his eagerness to break camp, he had

A CHROME EXTENSION FOR CONFIGURING RGB LEDS

Arduino News / By Ibrar Ayyub

Like pretty much all of us, [Andy Schwarz] loves RGB LEDs. Specifically he likes to put them on RC vehicles, such as navigation lights on airplanes or flashers and headlights on cars. He found himself often rewriting very similar Arduino code for each one of these installations, and eventually decided he could save himself (and
