I published my code for the IOIOSeek project to GitHub.
Fork it, do what you will.
My next step is to refine the project, add some automation, and make it cooler in general.
I grabbed a few thing to make that happen:
Second IOIO board for bootloader work…which will allow for bluetooth communications between the board and a phone. Two additional solar panels…to increase the complexity of my sensor setup.
Stay tuned…things should be in the works.
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…
Code…check
Components…check
Once I sew this all together, I’ll have a good one to post. Shooting for Sunday evening…
So, good news and bad news in regards to my IOIO servo controller project.
Good: I have published my code to GitHub. See…
Bad: Ytai, the creator of IOIO itself, let me know that my code is in need of an overhaul. Big time.
I am experiencing too much lag…losing a ton of time in the writing phase of my app. Expect an overhaul of said code, in preparation for my next project.
I have seen some activity on both of my apps on the Android Market. I feel some moral obligation to fix both apps, cite some versions, etc. This one could take some time, but should result in a pretty sweet project. On a strange note, Ytai has a sample app that handles the analog input that I need for my next effort. I should be able to stand up a project before too long…pretty pumped.
Anyhow, check that code if you are bored. Really bored. I will update when I get some decent code committed…until then…
My new amigos at Ytai’s Google Groups IOIO page and I are still spit-balling my project details. I am providing a circuit diagram to help the discussion.
For the fuller project in detail, check the original post. Cheers.
I can finally report a conclusion of sorts on the IOIO / PowerSwitch Tail project. The ‘of sorts’ disclaimer is in regards to my Android App, which is pretty much a working beta. I have some issues with my onResume code, and want to put some polish on the UI. That said, I have released the code to the interwebs, so had better provide a write-up.
The setup is the same as I have been posting. Dual open drain pins with a 10K pull to 5V do the lifting…triggering of pins is handled via my IOIO board…Android app providing a UI to do the switching.
I went ahead and published my app on the Android Market. It will pop for sure by searching for IOIO.
Price: free ninety nine. Can’t beat that.
I also tossed this code up on GitHub. Go nuts.
Video time: see this in action.
Basically, between all of the shaky camera work, I download my app from the Android Market, connect via USB, and control the 120V relay via my Droid 2. I will shoot a better video once I clean up my code a bit.
Stay tuned. The README on GitHub and the app details section should have all of the connection information. I can provide any further details via email / comments / @swantron. Have fun with this one…
