Development boards are assistant tools that help engineers and enthusiasts to become familiarized with hardware development. They simplify the process of controlling and programming hardware, such as microcontrollers and microprocessors. Electronut Labs, an embedded systems consulting company, had produced its new BLE development board “Bluey” with a set of useful sensors and NFC support. Bluey is an open […]
Description This project aims to build a thin, flexible smartwatch. It’s wrap-around display and touchscreen will allow it to display more data at a glance than current devices. Besides telling time and displaying notifications, the watch will feature pulse rate, blood oxygen, and step sensors for health monitoring. Details Planned Features 180mm x 32mm x

Mosquitoes are some of the most adept bloodsuckers on Earth. With a quick jab, sharp mouthparts plunge into human skin in search of a juicy blood vessel. It’s no surprise, then, that bioengineers have used the pest as inspiration for a device to periodically and independently sample the blood of individuals with diabetes. Finger pricking, the

Renesas Electronics Corporation announced the successful development of a new low-power SRAM circuit technology that achieves a record ultra-low power consumption of 13.7 nW/Mbit in standby mode. The prototype SRAM also achieves a high-speed readout time of 1.8 ns during active operation. Renesas Electronics applied its 65nm node silicon on thin buried oxide (SOTB) process to develop this

Spending an hour or two around any consumer-level padlock or house deadbolt lock with a simple lockpicking kit will typically instil a good amount of panic and concern about security. While it’s true that any lock can be defeated, it’s almost comically easy to pick basic locks like this. So, if you’re looking for a
What is it? This is a small (17.9 mm x 10.3 mm) breakout board with Bosch’s BME280 pressure, temperature, and humidity sensor as well as AMS’ CCS811 digital gas sensor. The sensors work in concert to provide a complete measurement via I2C register reads of indoor air quality including temperature- and humidity-compensated estimates of equivalent
There’s nothing better than “free” when it comes to just about everything, even PCB software. Just because some software is more expensive doesn’t make it better than some of those free PCB packages found on the Internet. In this round up, we will take a look at some of the past popular platforms that are
A neat little hacker project that’s flying off the workbenches recently is the Arduboy. This tiny game console looks like a miniaturized version of the O.G. Game Boy, but it is explicitly designed to be hacked. It’s basically an Arduino board with a display and a few buttons, anyway. [rv6502] got their hands on an

LTC7820 is, a high power fixed ratio charge pump DC/DC controller that eliminates the power inductor in a non-isolated intermediate bus converter, allowing up to a 50% reduction in circuit size and up to 4000 W/in³ power density. The 72V fixed-ratio DC/DC controller can deliver 500W. Non-isolated regulators and voltage level converters that employ energy
Linear applies switched-capacitor step-down topology for inductor-less DC/DC Continue Reading
At Sonnet Labs, a group of avid outdoor enthusiasts aim to democratize mobile communication with technologies that enable smartphones to send text messages, image data, and GPS locations without Internet connectivity, cellular coverage, or satellite reception. No need for cellular grid with Sonnet Therefore, they launched their product, Sonnet, the smartphone walkie-talkie! Sonnet is a wireless
