Detailed instructions of how to build an ATmega 1284p based data logger: [via] In this tutorial, a logger is built using a 3.3v Moteino MEGA with a 1284p CPU @ 16Mhz, w 4K eeprom,16K SRAM for variables & 128K program space. Considerably more than the 328’s 1K eeprom, 2K ram &...

SkyTraq announced a 12- x 16-mm size PX1122R multi-band RTK receiver for centimeter-level accuracy GNSS positioning applications. The receiver works with all the four global navigation satellite systems using GPS L1/L2C, Galileo E1/E5b, GLONASS L1/L2, and Beidou B1I/B2I signals...

Simon Kemper has published a guide for making use of the low-cost Dragino LGT-92 LoRaWAN asset tracking system to help track a bike when it’s stolen for easy recovery, while running for years on a single battery. Dragino LGT-92 is built for asset tracking across a LoRaWAN connection...

Stephen Holdaway recently announced his project, a beautiful vintage VQB71 7-segment display based GPS Clock. Inspired by the fantastic appearance of the LEDs, Holdaway explains that the clock was built with a handful of vintage VQB 71 seven-segment LED displays and an u-box NEO-6M GPS...

Researchers at the University of Michigan say they have developed a small, inexpensive, and highly accurate gyroscope that could help drones and autonomous cars stay on track without a GPS signal. The ultra-high-precision MEMS gyroscope - called the birdbath resonator gyroscope - is...

Zak Kemble published another great project. This time it's a Remote Mail Notifier with GPS functionality. He writes: At the moment I’m living in a block of flats and my mailbox is in a central lobby area. I’m often receiving small surprise packets from China and never know when the...

Argos is a satellite-based system that collects, processes, and disseminates environmental data from fixed and mobile platforms worldwide. What makes Argos unique is the ability to geographically locate the source of the data anywhere on the Earth utilizing the Doppler effect. The...

David Johnson-Davies writes about his experiments with interfacing a low-cost serial GPS module directly to uLisp, to create projects such as a GPS clock. He writes: I’ll also describe a GPS speedometer and odometer, and a simple navigator, in later posts. The module I used is the...
