Lantern: A New 925 MHz to 2175 MHz RTL2832U Based SDR for Satellite Reception

Our friends at RTL-SDR.com are reporting on a new SDR based on the RTL2832u. “It is called the “Lantern” and is being developed for the Outernet project. The Outernet project aims to be a “library in the sky” satellite based service that will provide free access to daily downloads of data such as books, news, […]

Sniffing Crazyflie’s radio with HackRF blue

arnaud acquired a HackRF Blue and has been busy coding up a GNURadio project for analyzing Crazyflie radio transmissions. Crazyflie is a nano quadcopter/drone controlled over a wireless link. The Crazyradio is the official radio dongle for the Crazyflie Nano Quadcopter. It is a 2.4GHz USB radio dongle based on the nRF24LU1+ chip from Nordic […]

BOMtools: Python scripts build Kicad part database

Steve Rodgers has been busy coding. He’s developed a set of Python scripts (BOMtools) which allow you to extract part numbers from a Kicad schematic and match them to a part number database. There are two scripts. One which does the part merge operation and is called from Kicad and the other which manages the […]

Android flight tracker uses ADSB data from RTL-SDR

Nikos has developed an Android app which works with the RTL-SDR dongle to demodulate the ADSB signal from aircraft and overlays the position of the aircraft on a high resolution offline map. So the user can use the App without Internet connectivity, on board an aircraft in real time! Nikos’ “Track your flight Europe” app […]

YOUSDR remote RTL-SDR software

Sixuniform has released YOUSDR v0.1 Alpha, an RTL-SDR webinterface for Raspian / Raspberry Pi. This is a web-wrapper for the rtl-sdr softwares. Currently it commands rtl_fm, rtl_tcp and dump1090. The software can be downloaded from its GitHub. The instructions on the GitHub page show how to set it up on a Raspberry Pi running Raspbian, […]

Arduino-powered turntable plays moon phases

While this turntable can’t play “Dark Side of the Moon”, it certainly can tell you which way it’s facing! This project by Yingjie Bei and Yifan Hu uses an Arduino to position a turntable and associated light source in such a way that the moon replica mounted on the turntable will be illuminated to demonstrate […]

ESP8266: Arduino compatible $5 MCU with WiFi

MAKE has posted Alasdair Allan’s three part series concerning the ESP8266 MCU. Alasdair highlights the capabilities and limitations of this chip, the installation and use of a supporting version of the Arduino IDE, and how to create a breadboard adapter for the ESP-01 breakout board (pictured above.) Via MAKE.

Arduino-assisted automatic 3D printed tea maker

If the earlier Arduino projects weren’t your cup of tea, try out this Automatic 3D Printed Tea Brewer. 24 Hour Engineer Brian McEvoy designed this project which uses the Arduino to control a servo which dunks the tea bag for a predetermined length of time for perfect brew control. The LCD readout provides information about […]

Arduino equipped inline sensor skates

Anurag Mishra writes, Recently I bought a new pair of Inline Skates. So an idea struck my mind. I modified my skates to give me some results. I wanted to measure the speed with which I am skating and if I get to know the surrounding conditions, that would be awesome. So, I brought an […]

ESP8266 WiFi module quick start guide

follower from rancidpacon writes, I recently wrote a 15-page getting started guide for the $5 ESP8266 WiFi modules for Kiwicon 8, a local New Zealand hacker con. It’s available as both HTML and a PDF. It provides details on: how to make the hardware connections using an FTDI Board or Arduino (with suitable disclaimer); how […]

TAPR/DCC video: System on a Chip – Programming FPGAs for Mixed Signal Systems

Here is the first of a four-part video series recently posted from the 2014 TAPR/DCC conference in Austin, TX. This is from the DCC’s Sunday Seminar, “a four-hour deep dive” into a single subject, in this case FPGA programming for mixed signal systems. “The presenter is amateur radio operator Chris Testa KD2BMH who is designing […]
