Project Preview

My new IOIO project is in the ‘bunch of pieces’ state.

It also happens to be in the ‘my effing hardware works’ phase as well..

I’ll keep mum on this for the time being…a bunch of coding and refinement remains to be seen. Stay tuned for this one…

Android IOIO Project | IOIOSeek

I hope you don’t mind, but I went ahead and stepped it up a few notches.

My newest project brings my end-goal a few steps closer. I now have the pieces in place to put together an actual robotic implementation with the IOIO…since things have officially reached the cool stage, I decided to drop this as a stand-alone project. Complete with pics, a vid, and an app.

IOIOSeek:

What I have here are two slider bar controlled servos, an analog input-read solar panel, and some LEDs toggled via a button. The control is via the IOIO / Android.

The pictures, however nice, don’t really tell the story. Take a look at the video to see this thing in action:

As the video alludes to, I am going to run with this concept. The automation (robotics) lies in the analog reading with respect to the servo positions. I plan to ‘scan’ the panel…that is the piece that is missing. Once I can implement that mess, I will have a tracking system. Implementations will fall out of that.

As with the last few projects, I have dumped the app on the Android Market for general perusal. The app’s description provides the details of the pin configuration, which is straight forward. I have two PWM outputs, a pure 3.3V digital toggle, and a pin configured for analog input. That is that.

I will push my code to GitHub as well eventually, and provide a link therein. I still need to polish my generic servo code, since my latency was borderline awful in retrospect. Look for that in the near future as well.

As always, drop any questions to joe[at]swantron[dot]com. Feel free to share your IOIO projects with me…

Once I sew this all together, I’ll have a good one to post. Shooting for Sunday evening…

Python Teaser

After a deal of success with the command line interface-to-Arduino project, I am in the middle of stepping it up a notch. I ended up on a few blogs due to that last effort, which indicates that I am doing something worthy of note. Hats off to me, perhaps. Well, my tool belt is what it is…if I can’t do it via shell scripting, I reach next for Python. In an attempt to parse stuff that I have been ‘getting’ via wget, I found myself trying to do some clunky regex from the command line. Guess what…I can do that without as much heartache via Python via BeautifulSoup…

so...beautiful

Thus far, I have python doing the website getting and Beautiful Soup doing the parsing of my site…basically just grabbing some info at this point that I can modify. I have my LCD driven via my trusty Arduino, and that is that. Instead of redirecting standard out to serial, I am writing to serial via python. Easy breezy.

I have some sloppy sloppy code at this point, and need to add some hardware and stuffs to my prototype. Stay tuned…this could be a good one.
