Updates on Kill-Switch (E-Vehichle for son).

During my latest testing phase, there was an accident with the motor controller.  This has put a small speed bump in my little project.

However, this may be a blessing in disguise.  I wanted to put in my own motor controller before, but I was trying to do this build without purchasing much.  So, I was using the built-in controller within the old hover board housing.  This came with many obstacles; for one, the circuit was very sensitive to change.  If I wanted it to work; the LEDs and everything had to be perfect. Otherwise it would throw errors. Keeping in mind that I do not have any manual, documentation, etc on the hardware here.

Once I replace their motor controller with mine, it will be even better for my automation.  I actually do have RPI motor controller HATs; however nothing rated for 500w.  So I am going to be using the following per side. http://a.co/eHzWM2i

This will allow me to control the speed with the battery, and hub motors I already have. Just add a potentiometer per side, and were in business. Those pots will be controlled via very small servo.  This will allow the user to control them, but the servos will put them back to zero (stop) after use.  This also enables the control via RPI3, as I mentioned before.

On another note; I am considering using casters in the front since you will be able to steer via the controls.  Alternatively, I get one controller and use it as a throttle only.  This would work, but then I would have to have front steering.

 

Thanks for all the support,

DIY Eclipse Glasses

Nothing Fancy here, but they work. (Use are your own risk)

First off, never look directly into the sun!  Always have the PROPER eye protection!

Supplies
1. Pen
2. Paper
3. Cereal box
4. Aluminum foil
5. Scissors

Yes, that’s it!

How to make an eclipse viewer yourself:
1. Put the cereal box on the piece of paper and trace the outline of the bottom of the box, creating a rectangle.
2. Cut out the rectangle.
3. Take two pieces of tape and make loops, then place them on both ends of the rectangle.
4. Take the piece of paper and place it inside the bottom of the cereal box tape-side down.
5. Close the cereal box up once the piece of paper is inside.
6. Create two holes in the top of the box, one on each side.
7. Cut the holes out with scissors — one will be for your eye, and the other will be covered by foil.
8. Tape the top of the box down revealing the two holes.

9. Take a piece of aluminum foil and cover one of the holes up (it doesn’t matter which one you choose.)
10. Take your pen, make a tiny hole in the middle of the aluminum foil.

And you’re done!

Thank you to all… Jasper v1.6 Image News!

First, I would like to say thank you to the community members for helping out. I have gotten a lot of input on the new image.  This has also given me better feel for what the community wanted in an image. Which leads me to the next bit of news.


Some of you are undoubtedly wondering why I have not released my Jasper v1.6 image as of yet.  Well, I can assure you there are very good reasons.

Firstly,  I have had some severe family/health issues come up as of late which take priority.  I am also in the middle of moving a family of 5.  Combine that with the other reasons below, and I feel that most will feel the wait to be worth it.

This leads me to the next bit of news, however shocking it may be.

  1.  There will be no version 1.6 image.
    1. There will be no image at all…
  2.  Instead, there will be a full installer.
    1. This is one of the reasons for the delay.
  3.   The installer will work with a full GUI, and on the desktop.
    1. Examples:
      1. Full ubuntu Install.
      2. Fresh RPI install with GUI.
  4. The installer will be iterated on by feature going forward.
    1. We can add community approved features one at a time.
      1. Example:
        1. Change Jaspers Name
        2. Change STT after setup
        3. Etc.

FAQ (COMING SOON)

  • So whats that mean for me?
  • What do I do if I am running Jasper v.15?
  • Where do I get the installer?
  • Do I need to upgrade?

 

How AI listens in Jasper (and others)!

 There are two basic kinds of listeners, an active and a passive.  You will not get good offline (passive listener) results for a wide variety of speech currently.  Most offline listeners are used as ‘passive’ listeners. They usually just listen for the wake word or just a few small commands.  They are very accurate but can’t sustain a large vocabulary without CPU issues.  Some are also closed source such as Kitt.ai (snowboy), and require that you train each word on their site.

The other kind, aka the “Active listener”; or the one always listening.  Would be used to listen once activated by the passive listener, and has a much more broad vocabulary.  However, these are online only. Due to the way they work (gathering metadata to increase accuracy), its just not possible currently on a small device. Examples would be standard APIs such as Google, Wit.ai, Ivona/Polly, etc.

There are projects to fix these offline issues, but they are all in the works. See my site for info on some of them. mattcurry.com
