Blindman`s stick

Blindman`s stick navigate vie ultrasound

Hi guys,

One day I went to work and had an idea. I wanted to get rich. My Idea was that: I´m building a blindmas stick. I wanted patented this idea, but I was too slow, because it has already been patented. Still, I wanted to build it. And there can you see it.

There is my Picaxe 28 at a Box from Polymorpf.

Ther can you see:

- a switch

- one LED and

- contacts for loading (+ and - 6V)

And there is the hooter.

There inside is one motor with unbalance for vibra.

And there are my glasses. They are covered with adhesive tape.

And now complete

I think this is on field where hobby robotics can really achieve something practical.  At the moment aids for the disabled are either horrendously expensive or limited.

With microcontrollers becoming cheaper and more powerful it should be possible to produce many new aids that were previously impossible or impractical.

Even if this idea was already patented there are many more ideas that haven't.

But how the blind man will see the diode and recognize that the device is 'on' ?

You're right. I did not think about it. This is only for me :).

This is a nice idea even you are too late :)

but...ahh...I would replace the LED...by a buzzer or something similar :)

The LED is only for signal. I have to see when it is "on".

I used: a buzzer for signal "distance to wall" and one motor for signal "distance to earth".
