In this presentation from the 2013 Digital Communications Conference, Bruce Perens K6BP discusses FreeDV, CODEC2 and “The HT of the Future”. Bruce is active in advancing interest in open-source digital voice to Amateur Radio on both HF and VHF/UHF. Here he also discusses D-STAR and Yaesu’s controversial new proprietary VHF/UHF digital amateur radio communications protocol.

OctoPROBER rev0 board update

Parker Dillmann posted an update on his OctoPROBER board  an 8 channel K-type thermocouple temperature logger, we wrote about it previously: I was having an issue with the FT230X being active while the 3.3V rails being turned off. The FT230X would backfeed voltage down the TXRX lines into the propeller which would power the 3.3V rail to ~2.7V causing […]

RTL_FM_Python: An API and web interface for controlling RTL_FM

Here’s an interesting piece of open source code known as RTL_FM_Python for controlling the RTL-SDR dongle. “This is a Python library built upon the RTL-SDR project and allows you to use the RTL-SDR dongle to tune in arbitrary stations either with a simple web application running on a built-in server, or programmatically with Python or […]

project ECHORD – Riverwatch

Eduardo Pinto informs us that the Riverwatch crew has finished the first phase of their project ECHORD – Riverwatch and have posted a first version of their site. The project is developing a Marsupial Surface-Aerial Robotic Team for Riverine Environmental Monitoring. One of the main goals of our project is to make everything open source […]

LEWE: the biometric wristband

Boris Landoni from Open Electronics writes about a new open source project the LEWE, a wristband that reads biometric: The Lewe project aims to collect and use available technologies to make a low cost idea that is applicable to all sectors using sensors for data collection. This project goal is the development of a communication protocol, […]

DiyouPCB low-cost PCB printer for photoresist

Charlie and Victor from Diyouware write, About a year ago my brother and I engaged on a quixotic project to build from scratch a low-cost PCB printer for photoresist. Finally we did it using a Blue Ray optical pickup (PHR-803T) and his UV laser/electronics to sensitize Dry-film. The optical pickup is used through his own […]

OpenBCI EEG project

The OpenBCI project is an open source project with the goal of expanding the availability of hardware for maker experimentation with brain wave measurement. It was recently fully funded on Kickstarter. According to the developers, OpenBCI is a versatile and affordable 8-channel EEG signal capture platform built around Texas Instrument’s ADS1299 Analog Front End IC. […]

DCC/TAPR video: HackRF – A Low Cost SDR Platform

In this talk from the 2013 Digital Communications Conference (DCC) co-sponsored by the ARRL and TAPR, developer Michael Ossmann discussed the origins and development of the HackRF Jawbreaker SDR transceiver. This is Michael’s first talk at an amateur radio oriented conference.

A new open source 200MHz logic analyer

Here’s an interesting open source 200MHz logic analyzer project on Kickstarter, the DSLogic by DreamSourceLab: DSLogic consists of DSLogic-Core and extension modules. DSLogic-Core is a re-configurable circuit board based on FPGA technology with maximum 200MHz sampling rate and 64Mbit on-board memory. DSLogic-Core can work alone as a fully functional logic analyzer, along with various extension modules.DSLogic can also […]

OpenMV Update: 25FPS face detection, USB support and more

mux posted an update on his camera project OpenMV, an open-source tiny machine vision module using an STM32F4 ARM Cortex-M4 micro and an OV9650 sensor: USB Support- The camera now supports USB OTG full speed, I’ve also written a small userspace tool with libusb/SDL to interface with the camera and view the frame buffer, this makes it […]

Digital Speech Decoder 1.7.0-dev adds D-Star support

DSD is a popular software tool for decoding various unencrypted digital radio protocols about which we’ve previously posted. We noticed that there is now a release of DSD which purports to be capable of decoding the amateur radio digital protocol known as D-Star. This is in addition to P25, X2-TDMA, ProVoice and NXDN offered in […]
