How-to: Bus Pirate v1, improved universal serial interface
We use the Bus Pirate to interface a new chip without writing code or designing a PCB. Based on your feedback, and our experience using the original Bus Pirate to demonstrate various parts, we updated the design with new features and cheaper components. There’s also a firmware update for both Bus Pirate hardware versions, with bug fixes, and a PC AT keyboard decoder. We cover the design updates and interface a digital to analog converter below. Concept overview The Bus Pirate started as a collection of code fragments we used to test new chips without endless compile-program-run development cycles.

Software Selection - Getting Started
Software Selection Most hobbyist and commercial users, as well as some educational users, program the PICAXE chip using the easy to learn BASIC language. This language is designed to allow users without any formal programming experience to be able to quickly and simply develop PICAXE microcontroller programs. PICAXE BASIC is much simpler to learn (and to 'debug') than traditional microcontroller languages such as assembler code or 'C'. The software for BASIC programming is completely free and available for Windows, Mac and Linux. Windows users should select the PICAXE EditorMac and Linux users should select AXEpad The PICAXE Editor software also includes a very useful on-screen simulation mode, where programs can be tested and ‘stepped through’ before downloading to the chip. Education Most educational users in high schools use the flowchart programming method, using the award winning ‘Logicator for PICAXE’ or PICAXE Editor 6 flowcharting software. More details...

How to Choose the Right Platform: Raspberry Pi or BeagleBone Black?
This article was originally posted at Michael Leonard’s blog and has been re-posted here. There are already many articles out there comparing Arduino, Raspberry Pi, and BeagleBone Black; this is not one of those articles. I believe it is clear that Arduino is in a different league than the Raspberry Pi or BeagleBone Black, and serves an entirely different purpose. What I was looking for and couldn’t find was a comprehensive article that would summarize all of the pros and cons of the Raspberry Pi and the BeagleBone Black, and what each platform is best suited for. When I couldn’t find that article, I decided to write it myself. I begin this comparison by giving a short introduction to each platform and then we will take an in-depth look at the two platforms side-by-side to determine which one is best for each category.

MIDIsense
This photo has notes. Move your mouse over the photo to see them. MIDIsense is a simple, yet extensible sensor interface system for artists, musicians and others interested in experimenting with sensors. The MIDIsense boards provide a simple way to integrate various common sensors with existing software such as Max/MSP, Ableton Live, etc. or directly to a synthesizer/sequencer with a MIDI in jack. Interface boards are available as kits and (possibly) assembled. While there are other projects with similar functionality, this one is the most technically advanced, flexible & inexpensive. This project is still in "beta" that means that it works well and has been tested but there are still bugs that pop up and the documentation may be incomplete. This project is supported by EYEBEAM (thanks!) If you have any questions/comments, feel free to ask on the Forum Why am I doing it this way?
