One of Ian’s projects featured at Hack a Day, a USB remote control receiver, was the 5th most popular project of 2009. We’re surprised the Bus Pirate didn’t make that list, but we’re proud of this project too. Our primary music and video player is a PC, we made this device because we needed it, and we use it daily to control Winamp and VLC.

This announcement is well-timed, as we’re currently putting the final touches on a new infrared receiver/transmitter toy. Look for this project in the next few weeks, but we’ll give away some prototype preview PCBs later today.

Thanks Hack a Day!

The web platform, December’s project of the month, is our second to be offered as a kit or as assembled hardware. We guessed that the kit would be the most popular option, but we were totally wrong. Seeed Studio’s latest report shows the assembled version is preferred almost 3 to 1. Is it the SSOP FTDI chip?

Seeed now lists assembled hardware by default, tick the box to get a kit instead and save $5. If you accidentally bought a kit, but wanted assembled hardware, there’s still time to contact Seeed to make a switch before the orders ship.

Thanks to everyone who supported this project. We’re busy working on an introduction to PIC programming for the web platform, look for that article next week.

The web platform is available as a kit for $35, including worldwide shipping. Seeed Studio will assemble yours for $5 more.

We sent a bunch of PCBs to Seeed Studio’s Fusion service this week. The open source logic analyzer prototype was the most anticipated board, you can get the final hardware for free if you suggest the name.

The final design candidates for the PIC high voltage programming adapter went to the board house too. Looking at the circuit board, can you tell why we chose an MC34063A boost regulator instead of the microcontroller driven switched-mode power supply in our earlier tests?

More PCB preview goodness below.

The Instructables version of the Twitter controlled Christmas tree is now online.

Dangerous Prototypes made it into Make’s open source hardware guide 2009! We got interested in open source hardware while reading Make and Hack a Day, this is a really special accomplishment for us.

Our hackable LED Christmas ornament is featured on the cover. The web platform, #twatch, and Bus Pirate are all listed in the development platforms and tools category. Thanks for the mention!


Fundamental Logic was the first company to offer a Bus Pirate for sale. Their Bus Pirate v1a through-hole kit is currently on sale for $20.  v1a is completely compatible with the latest firmware updates, the main difference between v1a and v2 & v3 is the connection type (serial vs USB) and the pull-up resistors (manual vs software controlled).

If you’re looking for a through-hole Bus Pirate kit, $20 seems like a great deal. Fundamental Logic had good prices on international shipping when we last checked.

Thanks Marc!


Seeed Studio just tweeted an update on Hack a Day’s second Bus Pirate preorder. Looks like they’ll ship in one week:

After long time waiting,we got ICs from Digikey. Now Bus Pirat Preorder 2 just started manufacture,will be ship out within a week.

Check out our Bus Pirate goodies when it arrives.

Bus Pirate firmware v2.1 release candidate 1 can be downloaded from the Bus Pirate project page. Learn how to update your firmware from Windows or Linux/OSX.


  • Experimental hardware I2C library for PICs that support it.
  • PIC chip revision detection.
  • New public domain I2C library, fixes bugs with read ACK/NACKs. I2C no longer GPL. More on the new I2C features tomorrow.
  • Universal bitbang abstraction saves a ton of space for new features, adds speed option to I2C, raw2/3wire, LCD.
  • Removed JTAG XSVF programmer, we ran out of space. It’s big, ugly, and I don’t think anyone uses it. It will be replaced with a real SVF programmer in an upcoming build.
  • Raw2wire macro cleanup.
  • Spelling, other translation fixes.
  • More
