Today we’re giving away an assembled Bus Pirate high-voltage programming adapter. It has a 5pin PIC programming header, a 6pin AVR programming header, and a small 13volt boost-converter power supply. A 13volt supply is needed to program PIC 12/16/18F microcontrollers, and clear the RESET fuse in AVRs. It’s doesn’t do much right now though, because […]

Winamp Status on Twatch
Andrew wrote a Python script to display Winamp playlist info on an ethernet-connected #twatch LCD: It’s pretty basic at the moment, but I thought people might like to see. I’ve got some speakers in my lounge room driven by my computer (long wires), this lets me know what’s playing. It shows artist on row 1, […]
Bus Pirate terminal update preview
Sjaak has been hard at work on a new terminal interface for the Bus Pirate. There are exciting new features like: A command history (h menu) Multiple command sequences can be processed at once ASCII character values are sent to the bus when entered between quotes (“text”) Mode changes now include an exit option Massively […]
Web platform: PCB in red
coolnicks posted this picture of the assembled web platform hardware from Seeed. Our prototype was on plain green PCB, so this is the first time we’ve seen it in danger red. Thanks for the pics! If you’ve just received your web platform, here’s some tutorials and links to get you started: Intro to dsPIC33 programming […]
Bus Pirate UART bridge with Wavecom GSM modem
will_j posted this picture of his Bus Pirate in use as a transparent USB->serial bridge to a Wavecom GSM modem. Thanks for the tip!
Demo: KS0074 serial LCD
This is an old version, see the latest version on the documentation wiki. Sjaak posted this demo of a KS0074 serial LCD in the forum: I needed to test the SPI library with the newterm branch. I had a nice display from a dead Siemens phone. It uses a KS0074 display (which is an sort […]
Free PCB Sunday II: Infrared receiver transmitter
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 PCBs from one of our past or future projects, or a related prototype. PCBs by Seeed Studio. This is another prototype PCB for the USB infrared remote control receiver/transmitter. […]
Free PCB Sunday I: Infrared receiver transmitter
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 PCBs from one of our past or future projects, or a related prototype. PCBs by Seeed Studio. This is the final version of the PCB for the USB infrared […]
Mystery EEPROM circuit
s3c is tantalizing us with this mystery EEPROM device. It’s a small I2C EEPROM data storage chip, and it appears to be powered parasitically from the I2C clock line. Was bored today so I opened a dongle I had laying around. It only contains an I2C eeprom and a couple of passives but it’s pretty […]
Bus Pirate v3 reference card
Torsten got tired of looking up the Bus Pirate IO table in the manual, so he made this handy spec and pin reference card: Please find attached my version of a quick reference card. The information is, due to the limitation of the sheet not very much. I tried to get the most important infos […]
SUMP PUMP challenge completed
We’ve been working on an open source logic analyzer prototype with Jack Gassett of the Gadget Factory. The project is currently known by the code name ‘SUMP-PUMP’, but you can help suggest a name. The design incorporates elements of the Butterfly platform, which is available now at the Gadget Factory. On Wednesday we offered a […]
Web platform: Introduction to dsPIC33 programming
See the latest version on the documentation wiki. There are reports of web platform deliveries in the forum, so we thought this would be a good time for an introduction to dsPIC33 programming. This introduction aims to help you start writing and compiling your own applications for the web platform. We cover lots of basics […]
Write an app, get a SUMP PUMP
We’ve been working on an open source logic analyzer prototype with Jack Gassett of the Gadget Factory. The project is currently known by the code name ‘SUMP-PUMP’, but you can help suggest a name. The design incorporates elements of the Butterfly platform, which is available now at the Gadget Factory. Update: Michal Demin completed this […]
Protostack v1.4 28pin AVR development board
Daniel Garcia, a friend of Dangerous Prototypes, released version 1.4 of the Protostack development board for ATMEGA8 and ATMEGA128. We really like the Protostack concept: it’s a general purpose development board that incorporates user feedback. It demonstrates the minimum circuit to get a 28pin AVR chip working, and has a large prototyping area to implement […]
Bus Pirate script for 8×32 LED matrix
will_j posted a Bus Pirate script that controls a Sure Electronics 8×32 LED marquee: Here’s a quick and dirty perl script to display ‘BPv3’ on a Sure Electronics 8×32 LEd Matrix display. You can also use a 16×24 display if you change the second command code to 44 from 40. Any improvements gratefully received – […]
Demo: HMC6352 digital compass breakout board
This is an old version, see the latest version on the documentation wiki. The HMC6352 is a simple compass chip with an I2C interface. If your next unmanned vehicle needs a compass, check out this chip. It has multiple operating modes that balance power use and update frequency. Continuous acquisition provides rapid heading updates, while […]

Prototype: USB infrared remote control receiver/transmitter
The most recent documentation is now on the wiki. UPDATE: there is now a USB IR Toy v2! Infrared remote controls are ubiquitous, they’re used everywhere but we don’t give them much thought. The goal of this project is to investigate the invisible signals emitted by remote controls. This IR hacking tool can visualize infrared […]
