Tutorial: Kali Linux with GNU Radio, GQRX and RTL-SDR dongle
If you’ve tried to install GNU Radio from binaries without success, this video from NeedSec is for you. He demonstrates how to intall GNU Radio on Kali Linux from source, and confirms operation of the RTL-SDR dongle using GQRX radio receiver software.
Reusing old Java ME devices in hacking projects
In this video from the Oracle Learning Library, Vinicius Senger and Marcelo Quinta demonstrate how to repurpose old Java ME mobile devices in hardware hacking projects. This talk, which was originally presented at last October’s Oracle Open World conference in San Francisco, concentrates on different ways to use Java ME for educational purposes, as well […]
DART programming language
DART is a new programming language for building structured web apps. DART is a new JavaScript replacement language. DART is a ground-up re-imagining of what JavaScript should be. It requires its own runtime environment (which Google makes available for free under the three-clause BSD license) and has its own syntax and libraries. DART is an […]
Open source JTAGulator identifies OCD connections
Famed hardware hacker Joe Grand has released his latest open source project, the JTAGulator. This tool assists hardware hackers in identifying on-chip debugging (OCD) and/or programming connections from test points, vias, or component pads on a target piece of hardware. It interfaces with your computer via USB communicating through any terminal program. It’s based on […]
Turning on/off lights by whistling (Cortex M4 @ 80FFTs/sec)
Limpkin informs us that he recently finished work on his open source project: Turning on/off lights by whistling Basically, it is an ARM Cortex M4 running 80FFTs per second to detect a whistling sequence. The project is obviously open hardware/source Via the forum. Check out the video after the break.
Zylin tiny open source CPU on FPGA
If you’re interested in experimenting with a tiny CPU implemented in an FPGA, we found this interesting article on using the Zylin Tiny CPU. AMR wanted a really small CPU core to handle things like loading ROMs from SD card. It had to take up a minimal number of logic elements and be easy to […]
The Liberator: 3D-printed pistol
Cody R. Wilson is a 25-year-old University of Texas law student working to build semiautomatic weapons using 3D printers. As depicted in this video, his efforts thusfar have concentrated on the part of an AR-15 semi-automatic rifle known as the lower receiver (the part whose sale and possession is regulated federally in the USA.) Recently […]
mbed’s BSD B.S.?
A couple days ago mbed, the ARM platform with a silly online compiler, announced that it’s register abstraction layer would be released under an open source BSD license. Readers raised the point that this is only partly true. We hate it when open source is used as a publicity ploy with only partial code releases, […]
CMSIS Components used by mbed are now BSD Licensed
Viswa writes, “ARM and mbed.org has released the components of CMSIS software under a permissive BSD license. CMSIS is common layer provided by ARM for accessing the core registers of ARM Cortex-M processor which inside Cortex-M MCUs. All Cortex-M MCU vendor make use of this library for the software drivers. This was until now under […]
Inside Minimatrix
In this video Nick Johnson demonstrates his tiny Minimatrix project and wrote a detailed explanation describing the build: While minimatrix is in principle a pretty simple device, there’s a surprising amount of detail that goes into getting it right – and some interesting lessons to be learned in designing and programming it. I thought I’d […]

Simple DIY ECG + pulse oximeter (V2)
Scott Harden has designed an ECG/pulse oximeter combo project using LM324 op-amps. Scott describes, “This new project is fully documented and uses extremely common and cheap parts, all of which could be purchased at RadioShack. It serves as both an ECG *and* a pulse oximeter, depending on which leads are attached. It uses a single […]
PiPurr remote cat interaction server
When the cats away, the mice will play. But…. what’s the cat doing when YOU’RE away? That question led Tris of CantHack, a group of geeks from Canterbury, UK, to develop PiPurr. Tris explains, “PiPurr is a simple client-server solution. The server runs on a Raspberry Pi, for low power consumption and provides the functionality […]
Project Fleatiny 8051-based board
Valentin Angelovski has developed Project Fleatiny, a 8051-based hobby board. “Project Fleatiny is a 100% open-source hobby-computer built around the 8051 micro controller. From a software point of view, Fleatiny consists of a sofware kernel (taking up from ~3K to 9K Program ROM area depending on installed kernel option modules) that essentially turns any fast […]
Open source RFID evaluation tools
A group from the University of Oulu (Finland) has developed and released a set of open source tools for auditing RFID signals. They describe, We have provided in this toolkit a systematic analysis for the RF protocol of RFID systems. The tools are either written for the Gnuradio software and the USRP software radio hardware […]
ChameleonOS open source Android ROM
