Bus Pirate, Built At Home (Hand Soldered)

Scott tested and programmed my hand-soldered Bus Pirate at the meetup last Monday. Apparently it works. Not sure when I'll actually use it, but nice to know it'll be ready to go....

Just wanted to post a high quality photo of the Bus Pirate board, Dorkbot PDX version.

Thanks Greg, Scott, Jim, Monty, Jared, and everyone else who had a hand in making this happen! :-)

Building the Bus Pirate at home

I delivered some Bus Pirate kits at the last DorkbotPDX meeting and I'm about to ship the kits to those that mail-ordered them. So I figured you might find some instructions helpful.

ShiftMatrixPWM Arduino Library Test

Thanks to Russel for this awesome battery, and of course Elco Jacobs for writing ShiftMatrixPWM.

Kinect Cat Sequencer

I went to the DorkbotPDX Open Lab today (Feb 26th, 2012) at ADX and sat down to play with the Kinect I got a while ago. The result is a "Cat Sequencer" that uses the Kinect to trigger samples. There are two looping samples and one non looping sample. The trigger areas for the samples have been placed around the plates. They are visible on the computer as cubes. The more solid the cubes the more filled the trigger area is. Once the trigger is filled enough, it plays a sample. Read on for more details and code.

AltSoftSerial Arduino Library

I recently published a new AltSoftSerial Arduino Library. It's meant as an alternative for Arduino's normal SoftwareSerial library, for more demanding applications that need simultaneous data transfer.

Building a Teardrop Trailer

I plan to go camping a lot in the summer and to make the camping more enjoyable I decided to build a Teardrop Trailer. I created a website where I'll log the progress with as many pictures as I can, tools I use and materials. If anyone is interested here it is: https://sites.google.com/site/buildingateardroptrailer/

DorkbotPDX BusPirate Board Design

For the many of you who are wanting a BusPirate, here are the design files. The Schematic, the Board and the Gerbers as a zip. Please review and comment - we don't want any errors in this!

Special thanks to Monty for the DorkbotPDX logo. Who knew what artistic talent he has? ;>)}}

Also thanks to Monty, Scott D. and Greg P. for comments and suggestions while I was editing the board and Gerbering.

Most of all, thanks to Greg for organizing this whole adventure and to Jared for setting us off on it to begin with.

announcing the return of the group order

I am pleased to announce that I am re-starting doing the group parts ordering service.

Favorite Visualization

I have a favorite visualization that I apply to conversations. Each participant is represented by a string. Each character of the string is one hour. Activity in that hour creates a blip. Inactivity leaves dots (or comma at midnight). Here are five days of Dorkbot project blabber visualized. I share my methods in the remainder of this post.

I prepared this chart in two steps: first get the data in a file and then plot it. Let's work backwards. Here is the plot routine:

DorkbotPDX Bus Pirate Group Order!
