This is an old version, see the latest version on the documentation wiki. The Logic Sniffer stores the FPGA (IC3) bitstream in a flash ROM chip (IC2). The PIC microcontroller (IC1) can update the bitstream from a computer using the multi-platform pump-loader application. This feature lets us release FPGA design updates with new features and […]

Bus Pirate: MAX147 ADC SPI demo
The MAX147 is a 12bit 8 channel analog to digital converter. will_j plans to interface a MAX147 to the web platform, but he used the Bus Pirate and the PirateShip GUI to learn about the chip first. There’s a screenshot of the terminal output in the forum. The Bus Pirate is available at Seeed Studio […]
Laser cut Bus Pirate v2go case
Stewart Allen liked Ril3y’s ideas of using layers of laser cut perspex for a Bus Pirate case, so he designed his own for the Bus Pirate v2go and an AVR Dragon board. You can download the design files at his site. Thanks for the tip! Here’s a complete list of the Bus Pirate cases we’ve […]
Introducing Dangerous Prototypes green, yellow, and red label
Our goal is to make stuff we enjoy, and offer it to like-minded hackers at a price we’d pay. We’re always looking for ways to improve the quality of our projects, but we still want to release prototypes for people who accept the risks of open source, enthusiast-designed hardware. We’ve settled on two major changes […]
Free PCB Sunday: Bus Pirate v3b
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 week we’re giving away two Bus Pirate v3b PCBs. v3b is a minor update […]
Bus Pirate PIC 24F programmer update
The Bus Pirate PIC 24F programmer will now successfully erase a PIC 24F and read the chip ID. In the future this could be a handy way to unbrick one Bus Pirate with another. Our goal is to make all Dangerous Prototypes projects repairable via a Bus Pirate programmer. We couldn’t get the commands in […]
Another laser cut acrylic Bus Pirate case
Mowcius has a new laser cut acrylic case for Bus Pirate v2go and v3. These will eventually be for sale in the Duinoday shop for about £12 ($17), including international shipping. Here’s all the cases we’ve cataloged so far. The Bus Pirate v3 is available at Seeed Studio and Adafruit Industries.
Logic Sniffer: SUMP with Mac OSX
For Mac users of the Logic Sniffer: sdixon shares how he got SUMP working on Mac OSX. You can back order the OLS at Seeed Studio for $45, including worldwide shipping. Don’t forget that Seeed now has probe cables for $6 each.
Bus Pirate in stock and shipping
A quick update on Bus Pirate availability: Seeed Studio has the Bus Pirate back in stock and ready to ship for $30, including worldwide shipping. Adafruit also has the Bus Pirate and probe cables in stock and ready to ship.
Web platform: uIP TCP/IP stack with interrupts, DMA
Here’s another update on the uIP TCP/IP stack port for the web platform. Bonybrown got the uIP stack to work with interrupts from the ENC28J60, and used DMA to transfer buffers to PIC memory. Performance wise – no real difference I can see from the ping times; theoretically, the biggest improvement will be in “responsiveness” […]
Bus Pirate: MMA7456L three-axis accelerometer
Starlino used the Bus Pirate to explore a Freescale MMA7456L, a three-axis accelerometer with both I2C and SPI interfaces. The surface mount chip is on a homemade though-hole breakout board, there’s also a tutorial on this handy adapter. You can get a Bus Pirate for $30, including worldwide shipping at Seeed Studio. Adafruit also has […]
Last web platform available
There is one more web platform in the Seeed shop, ready for immediate dispatch. We’re pretty sure this will be the last one, when it’s gone we don’t plan to make more. The web platform is $40 including worldwide shipping.
W1N9Zr0’s Bus Pirate PIC programmer
We previously posted this combined development board and Bus Pirate PIC programmer from W1N9Zr0. The C# source for the PIC programmer is now available in an archive, or grab it from the SVN. It uses the Bus Pirate’s raw-wire binary mode and an external 13volt power supply to program a PIC 16F628, but it can […]
Free PCB Sunday: Bus Pirate v3b
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 week we’re giving away two Bus Pirate v3b PCBs. v3b is a minor update […]
Logic Sniffer mention in Nuts & Volts
Openbench Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. This project is a collaboration between the Gadget Factory and Dangerous Prototypes. The Logic Sniffer got a mention in a Nuts & Volts article titled Reading and Writing an EEPROM Using the […]
Pirateship Bus Pirate GUI available for Linux
We previously covered the Pirateship GUI for the Bus Pirate . It looks like a Linux version is available now. Thanks for the tip Ronan! The Bus Pirate is available at Seeed Studio and Adafruit Industries.
A few words on Million dollar baby
Adafruit gave a presentation at Foo Camp about businesses that make money selling open source hardware. We’re ecstatic to be included in the ‘approaching a million in revenue’ category with household names like Evil Mad Scientist Laboratories, Bug Labs, and DIY Drones. It went down like this… pt sent an email to a bunch of […]
Video overlay shield for the Arduino
VideoOverlayShield is an Arduino shield that superimposes text onto a composite video feed. The board uses a MAX7456 on-screen display IC which is configured through an SPI interface. The MAX7456 stores 256 user-definable characters, so we’d guess it could also display icons and graphics with a bit of hacking. Thanks for the tip Eric!
Web platform: Telnet server hacking
Trev got the Microchip telnet server demo working on the web platform. Then, he took it further and hacked it to work with telnet clients on multiple systems. There’s a lot of great info about the Microchip TCPIP stack and telnet services in his writeup. We covered Trev’s earlier work with the Microchip TCP/IP stack […]
#twatch: Winamp plugin update
Yves released an updated Winamp plugin that controls the #twatch ethernet LCD screen: Changes include : custom char to display current playing status, new look for the progress bar, improved error condition handling (still not bullet proof but getting there), and my part for the environment, the backlight is now turned off when the playing […]
