In this post I’m going to write about my experiments with interfacing a low-cost serial GPS module directly to uLisp, to create projects such as a GPS clock: I’ll also describe a GPS speedometer and odometer, and a simple navigator, in later posts. The module I used is the GP-20U7, a small GPS module available […]

At the Maker Faire this year I got lots of questions about soil moisture sensors, which I knew little about. So I started seriously researching the subject. I found a few different soil sensors, learned about their principles, and also learned about how to make my own. In this blog post, I will talk about

u-blox has introduced the JODY-W2 multiradio module, a feature-rich and compact wireless module for automotive applications. by Ally Winning @ eenewsembedded.com Measuring only a 13.8mm x 19.8mm to address the space constraints that car manufacturers face, the module can operate in temperatures from -40ºC to 105ºC. The module is also well suited for industrial applications. The

The International Space Station (ISS) is one of greatest feat of engineering achievements by mankind. It is a space station (habitable artificial satellite) in low Earth orbit. The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields. The station is suited for

The official Arduino development team has this week rolled out new Arduino Cloud updates for tags, filters, blinks and galleries enhancing the workflow of the cloud IDE. Tags introduced a new way to filter your Things based on your custom metadata, templates has also been enhanced further with new broader templates (which support a whole variety of boards; not

A traditional early project for someone discovering a love for electronics has been for many years a metal detector. This would mean a few transistors back in the day, but today it’s more likely to involve a microcontroller. [Mircemk] has an example that bends both worlds, with a single transistor oscillator and an Arduino. This type

Integrated Device Technology has released what is said to be the world’s smallest 2W contactless-charging power receiver chip. In the future when all our internet-connected portable and wearable devices need a recharge after a busy day with their head in the cloud, contactless charging will be the way to go. The IDTP9026 wireless-charging receiver chip has a

The nRF5340 is the world’s first wireless SoC with two Arm® Cortex®-M33 processors. It is truly secure, and the combination of two flexible processors, the advanced feature set, and an operating temperature up to 105 °C, make it the ideal choice for professional lighting, advanced wearables, and other complex IoT applications. The nRF5340 is an

Allegro Microsystems’ device consists of a linear Hall sensor circuit with a copper conduction path located near the surface of the die. The Allegro ACS711 provides economical and precise solutions for AC or DC current sensing in <100 V audio, communications systems, and white goods. The device consists of a linear Hall sensor circuit with a copper conduction

[Larry Wall], inventor of Perl, once famously said that programmers have three key virtues: sloth, hubris, and impatience. It’s safe to say that these personality quirks are also present in some measure in most hardware hackers, too, with impatience being perhaps the prime driver of great hacks. Life’s too short to wait for someone else
