Still life of bearings for the new robot

Just updated my mac to Mavericks and the latest version of R, and poof, nothing works. Turns out that the good folks who make R decided to change the name of program from R64 or R32 to just plain R. If you run into this issue, just update your /usr/bin symbolic link paths and high five your nearest nerd.

add this to ~/.bash_profile and you should be good to goalias r=’/Library/Frameworks/R.framework/Resources/R’

Arduino + Open Logic Sniffer…works great.

On the left, is a an old duemilanove with logic sniffer code on it (sniffer), and on the right is another duemilanove (master) wired into a test board for a chip I want to incorporate into a new design (slave). The basic workflow is:

  1. write code for the host (I use textmate)
  2. upload via Arduino app
  3. master starts sending SPI signals to the slave
  4. record these signals using the sniffer board and software
  5. modify code

Here’s the relevant links:

(be sure to copy the relevant cfg files into the /ols-0.9.6.1/plugins/ folder)

I’ve already found several timing issues with my code because of this setup. It saves time and money. Happy hacking :)

Dave, No questions. Just wanted to say thanks for the Research Project template. I'm using it for a Masters project and it is working well. Bryan

Thanks Bryan! Good luck with your project!

Hi Dave, I've just discovered, or have I rediscovered something that I had forgotten I started? I have a New Forest & Waterside History research site that I don't remember starting. Even though I would have thought that most if not all, the information is known only to me. I see that it was last updated March 2011. Did I make it or did my computer create it?

The force is strong in you. You did not create it, your computer did, because it knows how badly you want to do forest & waterside history research. Boom, you’re a Jedi.
