Arduino + NES controller = USB keyboard

Grouflon has written up a unique project using an Arduino and an NES controller. “This week I worked on little script/manipulation that turns an Arduino and a NES controller into a USB Keyboard. Maybe it can be of use to some of you, so feel free to grab the code on this github repo. This […]

Academic paper: hacking with RF replay attacks

If you’re new to RF hacking you may have heard the term “replay attack” and wondered what it takes to implement one. In this academic presentation Practicing a Record-and-Replay System on USRP a group of researchers from the Shenzhen Key Lab of Advanced Communications and Information Processing and Shenzhen University, give a succinct and practical […]

Spoofing wattage info from a Dell power adapter with an MSP430

Xuan over at the 43oh forum writes: This is all about learning one wire protocol and I did learnt a lot. I think the most important thing is timing, with a uC working at 16Mhz or 8Mhz, you need to carefully counting how many cycles your interrupt routine takes and providing the logical level in time.  And […]

Single-lever and ultimatic adapter

Sverre Holm writes: Here’s an adapter that emulates both a single-lever paddle mode and the ultimatic mode. It is meant to go between a dual-lever paddle and an iambic keyer. The adapter has been implemented in an AVR Butterfly in C and it is compatible with Morse keyers such as the one in the Elecraft […]

RTLAMR: an RTL-SDR receiver for 900 MHz smart meters

It never ceases to amaze how many projects are developed making use of the RTL-SDR dongle. Bemasher has developed a software tool which interprets the signals in the 900 MHz ISM band sent from smart electric meters which are growing in popularity among utility companies. This project is a proof of concept software defined radio […]

VGA framegrabbing with TVP7002

desaster blogged about his VGA framegrabber project: The project got a nice boost when I found TVP7002 on TI’s site. It’s a video digitizing chip, featuring 3x ADC (one for each color channel) and a PLL system for generating the pixel clock from the HSYNC input. Compared to alternatives, this seemed to be quite nicely priced, and […]

DEFCON 21: Arduino based vehicle tuning device

In this presentation from DEFCON21, Albert Garcia Illera and Javier Vazquez Vidal discuss the development, Houston TX enclosed auto transport and operation of an Arduino based device for controlling automotive functions in 2010 and newer model vehicles that use the K-Line protocol (although we’re told it could easily be modified with newer protocols.) Additionally they […]

Mailbox wireless alert project

If you are waiting for some electronic parts to be delivered the wait can be agony. It is especially painful when you learn your parts which you desperately need have been sitting in your mailbox for most of the day because the mailman came early… This problem is solved by this Mailbox Wireless Alert Project. Re-purposing […]

GPS for graphing calculators

Kerm Martian from Cemetech has documented a GPS for graphing calculators project build: Graphing calculators are nothing less than powerful pocket computers, capable of doing many of the same things as smartphones, desktops, and laptops. Given that they have reasonably fast processors, a display, memory, and ports to interface with the outside world, I set out […]

electric imp-Controlled 120VAC relay switcher

Dillon Nichols blog about his electric imp-Controlled 120Vac relay switcher build:     I bought an electric imp about a year and a half ago when they were released. I loved it’s simplicity and made a few temporary projects involving it but wanted to keep it for something more advanced. After all this time, I decided it’s […]

BLE fun with Ubertooth: sniffing Bluetooth Smart and cracking its crypto

Mike Ryan writes about his latest efforts in BLE hacking. Hot on the heels of Omri Iluz’s BLE-sniffer-on-the-cheap, I decided to write up the BLE sniffer I built on Ubertooth. My sniffer highly robust, can capture data from connections, and is 100% open source. I also discovered a vulnerability in BLE’s crypto that allows me […]

30C3 video: Monitoring the Spectrum – Building Your Own Distributed RF Scanner Array

At the recent 30C3 conference in Hamburg, Germany, Andrew Reiter outlined his efforts in using inexpensive RTL-SDR dongles to build a distributed RF scanner array for monitoring and spectrum mapping. Software-Defined Radio (SDR) has increased in popularity in recent years due to the decrease in hardware costs and increase in processing power. One example of […]

RumbleRail, a standalone and modular Floppy disk jukebox

Watch and enjoy this RumbleRail project a Floppy disk jukebox by Kiu: The overall setup is completly modular. Each floppy is connected to its own floppy driver (rrfdc), which in turn speaks I²C with the main board (rrcmd). On power-on the main board auto-discovers the connected floppies and adjusts the software to utilize the available drives. In theory […]

Continuous temperature monitoring

Hlipka wrote a post on his blog detailing his continuous temperature monitoring build: Two years ago, when we returned from our skiing vacation, there was a nasty surprise waiting for us: with outside temperatures of down to -20° (celsius), our heating system had shut down. At one point, the pilot flame went out, and without it the heater could […]
