ToorCon 14 badge
Attendees at the recent ToorCon 14 conference in San Diego were provided this RF-enabled badge. Containing the same CC1110 radio circuit as the popular IM-Me, it’s a sub-1 GHz wireless transceiver controlled directly from your computer. The badge was designed by hardware maker Michael Ossmann, a Colorado-based engineer whose freelance embedded work has stretched across […]
AVR/V-USB combo tool hacks Win 7
András Veres-Szentkirályi, IT security expert, OSCP, GWAPT, writes, “I’ve built a device that acts as a USB HID keyboard, enters a script as a series of keystrokes into a PC, which can extract itself into an executable. This in turn can send files on the PC back to the device using the NUM/CAPS/SCROLL lock LED […]
R-Pi ARM-side source for BCM2835 SoC graphics driver released
The Raspberry Pi crew reports that the VideoCore driver code which runs on the ARM is now available under a FOSS license (3-Clause BSD to be precise. “The BCM2835 used in the Raspberry Pi is the first ARM-based multimedia SoC with fully-functional, vendor-provided (as opposed to partial, reverse engineered) fully open-source drivers, and that Broadcom […]
HackRF open source SDR
At the recently concluded Toorcon conference in San Diege, CA, developers Michael Ossmann and Jared Boone released the latest version of the HackRF board. “The HackRF project is developing an open source design for a low cost Software Defined Radio (SDR) transceiver platform. SDR technology allows a single piece of equipment to implement virtually any […]
Python module for transmitting and receiving infrared signals with an IR Toy
Crleblanc wrote a Python module for transmitting and receiving infrared signals with the IR Toy. It’s tested under Linux, Raspberry Pi, and is expected to work under Windows as well. It’s open source and hosted on the the Python Package Index (PyPI) linked above. I played around with the IR Toy python example and took […]
OpenBeacon – An open source active RFID project
OpenBeacon is a comprehensive open source platform for active RFID applications operating in the license free 2.4GHz ISM band. The project involves base station hardware, as well as active tag hardware. OpenBeacon is based on Open Source software and a very flexible and reprogrammable lowcost Open Source RFmodule. The firmware sources and hardware schematics are […]
uJ – a Java VM for microcontrollers
Dmitry Grinberg wanted to design a way to program MCUs that would be easy for beginners who don’t necessarily understand details of C such as pointers and memory management, yet don’t want to rely on common alternatives such as Arduino or PICAXE. He developed uJ: a Java VM for microcontrollers. “It implements the entirety of […]
An open source electron tube catalog
Here’s your daily retro fix. Electrontubes is an open source database of old school vacuum tubes (electron tubes). It features pinout, footprint, and some basic information about each part. This is an open source electrontube catalogue. Its database contents base type, pin-out and some parameters of components. This database is refreshing continuosly. If you are […]
Open source Bluetooth module firmware
Paul Sokolovsky developed a proof-of-concept open source firmware for common Bluetooth modules based on the CSR BlueCore4 cheapset. “BlueCore4-Ext is a popular Bluetooth chip used in many Bluetooth modules, some priced below $10. The idea is to create Wireless Sensor/Control Network using these modules, as Bluetooth is really ubiquitous technology nowadays, so any smartphone can […]
Open Hardware Summit 2012: USB and Open Hardware presentation
Here is a recording of the “USB and Open Hardware: A Sketchy History” presentation Ian gave at the Open Hardware Summit 2012. The presentation covers the history and conflicts between USB and Open Hardware. Audio feed is direct from the H1N and a lapel microphone. Shaky cam by our very own Mad Skillz. Ian tried […]
GNU Radio internals – how to use the framework
The availability of inexpensive SDR hardware such as the RTL-SDR and Funcube Dongle help to focus interest on the GNU Radio open source signal processing software. In this video from CCC Camp 2011 Marius Ciepluch delivers a case-study on how to analyze 802.15.4 (alias Zigbee) with USRPs on a real-time protocol (for send time verification, […]
Project Gado: open source robotic scanner
Project Gado was inspired by the work of the RepRap and Makerbot developers and was originally launched in 2010 as part of the Johns Hopkins University Center For Africana Studies’ East Baltimore Oral History Project. Their aim is to create a powerful, durable open source robotic scanner for sensitive archival materials which can be built […]
DakaRand 1.0: revisiting clock drift for entropy generation
In a recent post on his blog, security researcher Dan Kaminsky builds on the work of Matt Blaze and D.P. Mitchell’s TrueRand from 1996 while expanding on his Defcon 20 talk. In summary, any system with two clocks has a hardware number generator. The clocks’ tolerances lead to jitter, producing unmodelable noise in the system. […]
GSM GPS shield for Arduino
Boris Landoni draws our attention to the GSM GPS shield for Arduino designed by Open Electronics. “The shield is designed and based on the module GSM/GPRS SIM900 or the GSM/GPRS & GPS module SIM908, to make calls, voice and data connections via GPRS. This new version has several new hardware features, that allow maximum customization […]
Armpit scheme interpreter for ARM MCUs
ARMPIT SCHEME is an interpreter for the Scheme language (a lexically-scoped dialect of Lisp) that runs on RISC microcontrollers with ARM core. It’s being developed at the Fischell Department of Bioengineering of the A.J. Clark School of Engineering at the University of Maryland at College Park. They explain, “The name ‘Armpit’ was selected for this […]
NASA open source documentation
As part of the Open Government 2.0 initiative, NASA has been assembling a collection of links to open source code and projects on their open.nasa.gov site. “open.nasa.gov is a collaborative platform for the open government community to share success stories and projects they are working on. The content on this site is written by NASA […]
Workshop Video #37: USB and Open Source presentation 2012 first run through
This workshop video is an absolute first run-through of our USB & Open Source presentation for the Open Hardware Summit 2012. All comments are off the cuff. The final presentation needs to be just under 10 minutes. Don’t worry, there will be many changes: Explain the USB Implementers Forum with a line (via Twitter) Slide […]
