The APCO25 (P25) communications protocol is a form of digital radio communications technology growing in popularity in police and other public safety radio systems in the US and abroad. Many such systems are unencrypted and can be received on digital radio scanners. Others employ encryption in an effort to prevent civilian monitoring. Now researchers with […]

SkyNET air drone hacks wifi on the fly
Researchers at the Stevens Institute of Technology have designed and built the prototype of a WiFi hacking air drone based on the AR.Drone quadcopter. They added a lightweight single board computer with Debian Linux installed, along with 3G mobile broadband connectivity and two WiFi cards (the second for packet injection.) A GPS receiver and sonar […]
Transcranial magnetic stimulation device
This video describes a prototype of a transcranial magnetic stimulation device designed by Ben Krasnow. He explains: Transcranial Magnetic Stimulation (TMS) is a technique to stimulate brain tissue directly through the skull. It works by sending a very high current pulse through a coil that is located on the subject’s scalp. The fast-rising edge of […]
Web platform and Thermal Tweeter wireless tethering
The Thermal Tweeter needs a wired ethernet internet connection to get tweets. At the Open Hardware Summit and Maker Faire we’ll be lucky to have wifi. Likely we’ll need to use a 3G wireless connection. We need a way to bridge the wireless data services to a wired connection. Today we picked up a cheap […]
OsmocomBB: open source GSM software
Osmocom stands for Open Source MObile COMmunications. The crew developing the OsmocomBB (baseband) software project presented the above talk at the DeepSec conference last November in Vienna, Austria. As they describe their efforts: OsmocomBB is an Free Software / Open Source GSM Baseband software implementation. It intends to completely replace the need for a proprietary […]
DIY aerial drone spoofs cell towers, hacks wifi + Bluetooth
You’ve probably seen aerial surveillance drones. You also probably know that GSM towers can be spoofed to fool unsuspecting users into connecting and having their phone security compromised. Well at this year’s Blackhat conference recently held in Las Vegas, security researchers Mike Tassey and Richard Perkins demoed their Wi-Fi Aerial Surveillance Platform (WASP) capable of […]
Bluetooth Morse keyboard assists the disabled
In an effort to assist computer users with disabilities limiting their keyboard dexterity, the crew at Zunkworks developed this wireless Morse code based keyboard interface device. The user keys in the desired characters using the “dot” and “dash” buttons on the left of the board and the Arduino based device converts these Morse code characters […]
Wireless pixels
Andrea Belloni from SuLuLab writes: We realized this project for the “Arduino Day” in Rome 14/04/2011. For it we used two JeeNode (Arduino variant with wireless module on-board), one Rainbowduino + RGB LED Matrix and one PC with Processing. The Processing sketch generate the “plasma” animation and sends the images stream to the first JeeNode […]
Digi releases WiFi Xbee modules
Digi has announced the release of a WiFi version of the popular Xbee modules. They share a common XBee footprint with previous Xbee modules, and provide flexible SPI and UART serial interfaces. The product release sheet, getting started guide and other docs are available from the Digi docs page. Several models are available, including with […]
App note: BodyCom
The BodyCom system is a new short-range wireless connectivity technology that uses the capability of the human body to transport a few signals that provide intuitive, simple, and safe communication between two electronically compatible devices. Communication between BodyCom system devices occurs when they are within a few centimeters of the human body: a simple proximity […]
OpenPicus WIFI development board winner
Today we announce the winner of the OpenPicus WIFI development board. There were lots of creative project ideas, thanks for your submissions. Congratulations to Tom, his idea for WIFI-controlled theater props scored him the OpenPicus starter kit: I build custom lighting, props and scenic effects for the theatre.As these things are very mobile on the stage, […]
Infrared serial link using PIC18F452
Chris from PyroElectro writes us with this useful project to communicate serial data over an infrared link. Here’s an article that explains how to create a wireless infrared transmitter using an IR LED and a wireless IR receiver using a phototransistor to make a communication system. Asynchronous serial is transmitted over this link at 9600 […]
Reminder: OpenPicus WIFI development board giveaway
Today is the last day for the OpenPicus Nest starter kit giveaway. If you’d like one just leave a comment with a project idea. We’ll give it away later in the day.
Giveaway: OpenPicus Nest starter kit
Tomorrow we’ll give away a Nest starter kit. If you’d like it just leave a comment on yesterday’s post with a project idea.
OpenPicus WIFI development board giveaway
OpenPicus gave us a Nest starter kit WIFI development platform to give away. Leave a comment on this post with a project idea, and it could be yours on Thursday. OpenPicus is working on open source wireless hardware and a free application development platform. The current WIFI hardware has a PIC 24FJ256GA106 microcontroller, and an […]
OpenDuino hackerspace monitor
The Luxembourg based syn2cat hackerspace has a system in place to provide members with information on the open/closed status of the space online or via an Android app. They call it OpenDuino, and it is more than a web based status monitor. OpenDuino also operates as a security system, allowing members to open and secure […]
Quick and easy wireless using R/C and PIC 18F452
Chris from PyroElectro writes to inform us of his new wireless project: It takes a standard hobby R/C radio transmitter/receiver system and interfaces it to a PIC microcontroller to control a Motor and LED brightness. Named the Quick and Easy Wireless system for it’s off-the-shelf style. Project details including schematic and C code can be […]
Pirate fighting surveillance robot
Relax, it’s not looking for THAT kind of pirate. This robotic creation by Recon Robotics is known as the Throwbot and is designed to be launched from a ship mounted cannon. It either lands on the pirate’s ship or the metallic sides which it then scales (as demonstrated in this video.) Once on board it […]
Freescale’s MC13260 two-way radio chip
Freescale’s MC13260 System-on-chip two-way radio is one chip to watch for. Now in the “introduction pending” stage and highlighted in this video from the recent FTF 2011 conference, it promises to be a one chip analog/digital radio solution. Preliminary design specs show RF coverage from 60-960 MHz, comprehensive digital radio mode coverage including DMR, dPMR, […]
Wireless networked AT keyboard
Creative technology student Pieter Pelt and Hybrid Worlds present this project detailing how to connect an old AT style computer keyboard to a PC via Arduino and Xbee modules and using the Teensy PS2Keyboard library. Using Xbee allows for keyboards which are not only wireless, but also networked so that several keyboards can be meshed […]
