Henryk Plötz and Milosch Meriac gave a presentation at the recent 27C3 Chaos Communications Congress in Berlin, Germany, in which they demystified the HID iClass. One of the challenges of breaking iCLASS RFID readers was to extract the firmware and the security keys of RW400 readers without leaving visible traces like breaking the case open. […]

RGB LED flower
This LED flower is controlled by AVR with software USB stack. It contains 6 RGB LEDs which are at the end of twisted enamelled copper wires. Project is well documented with extensive tutorial. Via mcu.cz
V-USB: virtual USB port for Avr microcontrollers
V-USB is a software-only implementation of a low-speed USB device for Atmel’s AVR® microcontrollers, making it possible to build USB hardware with almost any AVR® microcontroller, not requiring any additional chip. V-USB can be licensed freely under the GNU General Public License or alternatively under a commercial license. An example of the hardware needed to […]
NEW PROTOTYPE: USB Universal LCD backpack
The USB Universal LCD backpack controls LCDs with up to 16 interface pins at 3.3volts or 5.0volts. This includes common HD44780 character LCDs and larger graphical LCDs. Small backpack mounts behind most LCDs USB control for common 1×8, 1×16, 2×8, 2×16 … up to 4×40 character displays and some graphic displays 3v3 and 5v LCDs […]
Embedded USB design by example
This practical USB engineering guide provides examples of how to make USB devices and embedded USB hosts. Thanks McZ!
USB Hacking with the Arduino
Here Collin’s Lab at Makezine explores the use of microcontrollers as USB host controllers. Very instructive and worth a look by anyone wanting to learn more about USB and its integration with microcontrollers. Via Makezine
USB port in wall gives new meaning to file sharing
What would you do if you saw a USB connector sticking out of the wall in a public place? Makers in New York City want find out! They’re launching project “USB Dead Drop”, an anonymous, offline, peer to peer file-sharing network using USB flash drives embedded into walls, buildings and curbs accessible to passersby. Just […]
Tiny USB business card
A cool USB business card. This one is a little different than some of the mass storage device business cards we’ve covered before. It enumerates as a keyboard and dumps contact info into notepad. Via Hack a Day.
PIC LCD backpack with LCD Smartie
This is a prototype of the open source PIC LCD backpack driven by LCD Smartie over a USB virtual serial port. Follow our progress in the development thread.
Preview: USB LCD backpack prototypes
Soldered prototypes for the FT232-based USB LCD backpacks. Check out the design on the wiki, and follow development in the forum.
mini USB LCD backpack
This is the mini version of the USB LCD backpack . It has only the IO pins required for the most common HD44780 LCD pinouts. Join the development discussion in the forum. Driver development is under way for LCDsmartie. We’ll be adding support to LCDproc too.
Free PCB Sunday: USB RGB color changer
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few professionally-made PCBs from one of our past or future projects, or a related prototype. This is a USB controlled RGB color changing light. Someone made some minor modifications to […]

USB to serial adapter in DB9 footprint
There aren’t many simple ways to add a USB interface to a project using only through-hole parts. This USB-serial adapter from FTDI has the same shape and pinout as a through-hole serial connector. It’s a little pricey (~$22), a USB->serial cable is usually cheaper, but it’s a nice option for a professional-looking USB device without […]

USB Performance Monitor
We like the professional look of this USB PIC (18F2550) project from WaitingForFriday. Analog VU meters and an RGB LED show system stats like CPU use, network speed, and hard disk activity. The PIC enumerates as a driver-less USB HID device with a firmware based on the Microchip USB stack. via Hackaday
