Continuous monitoring of heart activity permits measurement of heart rate variability (HRV), a basic parameter of heart health and other diseases. This Design Idea is a new design of pulse oximetry that excels in its simplicity and functionality. Due to its capabilities, it can be used as a standalone device, able to monitor heart rate […]
MATRIX Industries’ nanopower energy harvesting boost converter with microwatt cold-start, input impedance matching, and regulated output MATRIX Industries’ Mercury is a family of highly integrated DC/DC boost converters that are ideal for harvesting and managing surplus energy from extremely low input voltage sources such as TEGs (thermoelectric generators) and thermopiles. The patented transformer reuse topology

The official Arduino development team and engineers have this week announced that the excellent Arduino Project Hub will be “evolving“. A new Project Hub will be launching in beta later this month on December 29th, ready for the New Year. Providing a newly revamped version of the existing Project Hub at the same URL https://arduino.cc/projecthub replacing the old Hub
Ghostwriter is a unique typewriter that has been retrofitted with a little Arduino hardware and coding to create and AI typewriter which features an integrated artificial intelligent co-writer. Check out the video below for a quick demonstration of the systems functionality. The project has been created by Arvind Sanjeev who explained a little more about the inspiration behind the AI
The BBC Micro:bit, while not quite as popular in our community as other microcontroller development boards, has a few quirks that can make it a much more interesting piece of hardware to build a project around than an Arduino. [Turi] took note of these unique features and decided that it was the perfect platform to build
Consumer electronics aimed at young children tend to be quite janky and cheap-looking, and they often have to be to survive the extreme stress-testing normal use in this situation. You could buy a higher quality item intended for normal use, but this carries the risk of burning a hole in the pockets of the parents.
COM modules with NXP i.MX 8M Nano CPU High performance in a compact format Based on the NXP® i.MX 8M Nano applications processor, F&S Elektronik Systeme has developed an inexpensive CPU module (35x40mm) with many industrial interfaces and extensive software support. The heterogeneous multi-core processor consists of up to four Arm® Cortex®-A53 cores (1.5GHz) and an
In this circuit we use the output signal from a standard IR receiver (IC1 in the schematic of Figure 1) to drive a miniature loudspeaker. The IR receiver from Vishay used here is available for various frequencies ranging from 30 to 56 kHz. A large number of IR remote controls operate according to the so-called RC5 protocol that
