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

This is a nice idea even you

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

but…ahh…I would replace the LED…by a buzzer or something similar :slight_smile:

The LED is only for

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”.

great idea

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