3.3V/3A, WIDE-INPUT, SYNCHRONOUS, STEP-DOWN DC-DC REFERENCE DESIGN

The MAXREFDES1048 synchronous step-down dc-dc converter reference design from Maxim Integrated Products is based on the MAX17504, a high-efficiency, high-voltage, synchronously rectified step-down converter with dual integrated MOSFETs can operate over a 4.5V to 60V input. The MAXREFDES1048 reference design operates over an input voltage range of 18- to 36-Vdc and delivers an output of 3A. The MAX17504 can deliver up to […]

PSYLINK AN OPEN SOURCE NEURAL INTERFACE FOR NON-INVASIVE EMG

Arduino News / Tismail

We don’t see many EMG (electromyography) projects, despite how cool the applications can be. This may be because of technical difficulties with seeing the tiny muscular electrical signals amongst the noise, it could be the difficulty of interpreting any signal you do find. Regardless, [hut] has been striving forwards with a stream of prototypes, culminating in

ARDUINO OLED HYGROMETER AND THERMOMETER USING DHT11

Electronics News Updates / Tismail

Hygrometers are used to determine the moisture content of the environment. They find application in farms, food storage, museums, and other places where moisture needs to be monitored to ensure damage is not done to goods and other things stored in that space. For today’s tutorial, we are going to build a Hygrometer using the

A NIXIE CLOCK, THE HARD WAY

Arduino News / Tismail

Notice: no vintage Hewlett Packard test equipment was harmed in the making of this overly complicated Nixie clock. In fact, if anything, the HP 5245L electronic counter came out better off than it went into the project. We mention the fate of this instrument mainly because we’ve seen our fair share of cool-looking-old-thing-gutted-and-filled-with-Arduinos projects before, and

(GETTING RID OF) THE GHOST IN THE LED

Arduino News / Tismail

Multiplexing is a very old technology in which control signals are intermixed for the sake of being able to control more devices than there are control signals. For [mihai.cuciuc], the problems started when he multiplexed some very efficient LEDs. The problem? In two banks of six LEDs each, both LEDs connected to a single Arduino pin would light,

ANNOY YOURSELF INTO BETTER DRIVING WITH THIS TURN SIGNAL MONITOR

Arduino News / Tismail

Something like 99% of the people on the road at any given moment will consider themselves an above-average driver, something that’s as statistically impossible as it is easily disproven by casual observation. Drivers make all kinds of mistakes, but perhaps none as annoying and avoidable as failure to use their turn signal. This turn signal

CELLULAR PANIC BUTTON REVEALS AN NB-IOT FUTURE FOR PERSONAL SAFETY ALARMS

Electronics News Updates / Ibrar Ayyub

Nordic Semiconductor announces that Dutch startup, Montr, is employing Nordic’s nRF9160 multi-protocol LTE-M/NB-IoT System-in-Package (SiP) in a small lithium battery-powered NB-IoT emergency alarm designed to protect people in vulnerable situations such as lone professionals at risk of physical attack or isolated accident, and seniors living at home. The 58 x 42 x 6 to 24mm

MYSTERY HP GEAR TEARDOWN

Arduino News / Tismail

What’s round, has what looks like a vacuum tube in the center, and was made in the 1950s by HP? We don’t know either, but [The Signal Path] restored one and shows us this mystery instrument in a recent video that you can see below. We aren’t going to spoil the surprise over what the device is,
