There’s something about Reverse Polish Notation (RPN) and the calculators that use it. It calls to mind a time when a calculator was a serious tool, and not just a throwaway toy. Created in the legacy of such calculators by HP and Texas Instruments, [Simon Boak] shows off his SB116, sporting an Arduino Nano under the […]

This is one small project which I had done with Abhinav Gupta some months back. In this experiment, I graduate from using simple RF communication to Xbee! Whoa! Ok, so here is the basic problem statement. I need to develop a temperature sensing system such that the temperature from the sensor node is relayed to

GaN Systems and ON Semiconductor announced the availability of the NCP13992UHD300WGEVB, the world’s highest power density 300W ac-dc adapter reference design using GaN Systems’ 650V, 15A gallium-nitride (GaN) E-HEMTs and multiple ON Semiconductor controller and driver ICs, including the NCP51820, NCP13992, NCP1616, and NCP4306. This complete system reference design is a highly versatile and low cost, allowing designers to

Good news out of Mars from the little lunchbox that could — in the seven times that MOXIE has run since it arrived in February 2021, it has reached its target production of six grams of oxygen per hour, which is in line with the output of a modest tree here on Earth. The research team
Thanks to a host of useful feather wings and shields, the Adafruit Feather form factor is becoming a very popular one with a host of other boards now based on it, offering not only the shape and size but also pin compatibility to allow the use feather addons like the FeatherWings and shields. In line with this, Arturo (@Arturo182) recently announced

[ArduinoNmore] took an interesting approach to designing a counter intended to accurately display how many meters of filament a 3D printer has used. The Filamentmeter looks a little bit like a 3D printed handheld tally counter (or lap counter) but instead of a button to advance each digit, the readout represents how many meters of filament

The official Arduino development team has unveiled a new Arduino Cloud CLI tool this week to make most tasks possible when programming and developing on the Arduino platform possible using a web interface. Devices and things can be created, deleted and listed. Things can be bound to devices. In a very similar way it is
[Neumi] over on Hackaday.IO wanted a simple-to-use way to drive stepper motors, which could be quickly deployed in a wide variety of applications yet to be determined. The solution is named Ethersweep, and is a small PCB stack that sits on the rear of the common NEMA17-format stepper motor. The only physical connectivity, beside the motor,

After playing second (maybe third?) fiddle for a while to a range of maker-friendly boards from Arduino and others, STMicro finally got it right with the STM32F103C8T6 Arm Cortex-M3 microcontroller-based “BluePill” development board which can be programmed using the Arduino IDE. As all good hardware requires, a new version of the board which is being called the “Blue Pill 2” or “Black

Augmented and Virtual Reality rank among the top 10 technologies driving Industry 4.0 and while they are having a huge impact on the development of new devices, it’s interesting to see them also being used as a major ingredient in the technology development process. This was one of the reasons why a while back we took a
