RE: GPS Voice Controlled Guiding Stick for Blind people #1: Introduction

llanyort — Tue, 28 Apr 2020 21:29:38 GMT

could we add a DUAL capability feature ?

mode 1 - GPS.

mode 2 - audio feedback of localized/nearby objects. Higher the pitch the closer the object.

make it a "tight" focused detection beam(not a shotgun/spread out area detection)

having these two modes, could help those "learn to see and explore" WHEN gps coverage is not available.

Hello,

Do you have any info if KDS support KV4 and KV5?

Hi Doug

I have a favour to ask you. I am roadtesting the FRDM-KV31, LVPMSM motor controller and Linix motor. After reading your design challenge blog, and downloading various documents, it is clear that getting these components to work with the Kinetis Motor Suite will depend on exactly the right combination of obsolete software. I also found that the KV31F boards come with different firmware, depending on their age.

To save me hours of pain (like the 33+ hours you experienced), it would be great if you could firstly check what your KV31F board enumerates as when you plug it into a PC. This assumes a) you still have it, b) you can still find it!

It should either show up as MBED <drive letter> , or FRDM-KV31F <drive letter>.

Next, can you remember or have you a note of, which versions of:

Kinetis Motor Suite
Kinetis SDK

worked with Kinetis Design Studio v3.0 and the hardware you were sent? I appreciate that almost three years have elapsed since this project.

Any answers at all would help narrow down what I need! I asked NXP for some help but they said that they "will no longer be licensing" KMS and pointed me towards MCUXpresso (without KMS). I can do this, but I'd rather have a play with KMS first.

Thanks in anticipation.

Steve

Nice update [mention:193ac2434c814a24b46635a2210baec1:e9ed411860ed4f2ba0265705b8793d05]

I'm surprised at the temperatures (+26... unless it's a typo) you reached just using reflected sunlight.

As you say the days that it can be used are minimal, abut maybe it could help after a prolonged event when the temperatures are even lower.

If you build one in a basement, make sure it will fit up the stairwell.

Funny ... I've heard that about other projects as well, and at least you didn't need to remove a large window, or door frame.[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-7e4ff9f6-e886-4884-8cd2-234ec811c0c7/contentimage_5F00_938.png:16:16]

As a proof of concept you've succeeded, well done.

Dougal,

I have a large 3x3.5 foot mirror, setup on a stand that is manually adjustable in Az & El that you could use as a Primary mirror to align the sun rays onto your gizmo so that it could be optimally positioned to direct the sun to your target. It might even fit in your van without disassembly. Properly setup it would probably increase the directed power by a large margin. But since it is manually adjusted it would only serve as a proof of concept. I would guess that it would give you around 45 minutes worth of sun before needing adjustment.

Nice update Douglas.

I would suggest using a curve on the mirrors, so that you can concentrate the sun energy on a smaller area.

Your results were about what I expected given your design.

Good test though.

The idea of beaming the light into the window is kind of interesting, especially if you had plants growing in that window.

My greenhouse doesn't get as much sun in the winter, because it's partially blocked by the house. Some well-placed mirrors might be useful.

If I was still in my old home in Queens NY, I would seriously give this project consideration for that home. It has treacherous entry ways during November to March.

What a fabulous concept!

I am a bit concerned.

You are putting a lot of stress on the motor with the way you have attached it to the two parts.

You have both angular issues as well as rotation forces that could potentially really compromise your motor function.

You might want to consider adding a hinge to the joint and then use the motor to just move the bar allowing ;the joint to absorb most of the force.

Just a thought,

DAB

RE: EyePrints - Post 17 - Final demo

amgalbu — Tue, 05 Jul 2016 06:33:31 GMT

Thank you DAB

You are right: the eye tracker could be used as a basic "mouse".

To stay in the challenge topic, it could be used to control a wheel chair

Cheers

DAB — Sun, 03 Jul 2016 19:23:16 GMT

Good summary and demo of eye tracking.

I can see a lot of uses for your basic software. Once you get the camera calibrated, you could control a quadcopter, RC vehicle or aircraft, or just use it for basic device control.

Nice project, well done.

Be careful what you wish for.

I have seen snow in western Canada in August, so you might have an opportunity to test your system sooner than you realize.

Nice update Douglas.

In my experience, anything I toss is desperately needed within one week of absence.

So as long as I have storage room, I keep old gear. You just never know what becomes valuable until you need it and don't have it.

Unfortunately it is, but I have just figured out what to do and tried to complete the project by deadline. That is what challenge really means.

Nice update.

The smooth motion should be useful when you get outdoors.

It looks like you have enough torque to hold up to some good wind speeds.
