Thanks for testing. I am syncing a new image, with all good luck, the last.

Re: Sight for the Blind for <100$

be sure to make sure that a-update.sh is executable!

a quick

sudo chmod +x a-update.sh

will do the trick.

Re: Sight for the Blind for <100$

And here is the solution. replace the contents of /home/pi/a-update.sh with the following: #!/bin/sh cd /home/pi/After-Sight-Model-1 git fetch --all git reset --hard origin/master chmod +x *.sh echo "Now run: a-update_core.sh, a-update_voice.sh or a-update_teradeep.sh from the /home/pi/After-Sight-M...

Re: Sight for the Blind for <100$

I have discovered an error in the update mechanism. there is a script in /home/pi that you will need to edit or replace. unfortunately, I can't fix this any other way (ie. you can't run the updater to fix it). it is the script a-update.sh It currently reads: #!/bin/sh cd /home/pi/After-Sight-Model-1...

Re: Sight for the Blind for <100$

I have integrated the contrast code, and it is much nicer. I have noticed though that when contrast is set to 0 that I get nothing. I had added the zero setting to the cycling in the menu so that it was 0,1,2,3 at the next opportunity, dropping the 0 seems like a plan. The other settings have a nice...

Re: Sight for the Blind for <100$

Thanks, when I get home I will look it over. Basically, at this time it recompiless raspivoice and teradeep each time an update takes place. This will be helpful later tonight when I try to add your contrast Code. if they are still working, then everything compiled fine. From what I gather, the step...

Re: Sight for the Blind for <100$

fair enough. I will take a stab at yours tonight.

I'm just far less confident in cpp than python. I will do it if I can though.

Re: Sight for the Blind for <100$

I have created the update with contrast setting. Peter: I did not use your code because raspivoice already has a command line flag for changing the contrast. I used this. Please see that it meets the needs. If it is vastly inferior we can rework the code directly. I played around with the values, an...

Dustin,

How much is the array? How often do they need to be replaced?

I can see some very useful possibilities.

Hi mc700bi We welcome intrusions and new ideas. At the moment our device does not have gps.

Re: Sight for the Blind for <100$

I have completed both images for the rpi v2 and v3. I am not in a good place to upload though, so it will be a few days before I can get them online. In that time, I will attempt to get the next update prepared which will be the contrast setting. This way, once you download the image, you can plug i...

Re: Sight for the Blind for <100$

I'm finished the updater and confirmed it working on the pi v 3. Now I am working on my last pi v 2. I should not have to change the stuff submitted to git at this point to make it work. I may have to do a bit of fighting with installing dependencies though, so... What I propose is this: I will get ...

Re: Sight for the Blind for <100$

I feel a little silly. All those warning were irrelevant, and all I had to do was chase down and install libGL. that was a challenge. As with raspivoice, a lot of installing/uninstalling/reinstalling dependencies. For anyone facing this trouble in the future, it requires two versions of libavcodec53...

So I have been quite busy getting the updating function to work. When I previously thought I was 50% complete, that was more like 10%. I'm hoping Mikael can help me with this one: gcc -Wall -c -fopenmp -fPIC -D__NEON__ -mcpu=cortex-a7 -mfpu=neon -O3 test.c gcc -Wall -c -fopenmp -fPIC -D__NEON__ -mcp...

Re: Sight for the Blind for <100$

I am making progress on the updater. In fact I would say I am about 50% complete. Regarding the battery shutdown notice, I can increase it to ten minutes, but I have no way to estimate the life left in the battery. I expect different people to use different applications, and I am certain the consump...

Re: Sight for the Blind for <100$

So, there have been a few hurdles over the past few days, and I think I'm coming around the bend on them a little bit. Although everything appeared to be working, it became apparent this was not the case. The serial port on the raspberry pi v 3 was not functional. It seems like they did some strange...

Re: Sight for the Blind for <100$

surprisingly it didn't actually take too long to get everything going. What I did: copied the home folder from my raspberry pi v 2 into the home folder on the raspberry pi v 3 using a modified installation called minibian which is a minimized debian install. I don't know the final size yet, but mini...

Re: Sight for the Blind for <100$

I am currently rebuilding on the raspberry pi v 3. My first impressions are that default settings run hot and by necessity must be chewing through battery life.

I'm thinking about underclocking a little bit.

It hasn't been fixed yet. Perhaps that can be the autoupdate test case. It is a smaller job than getting BT going anyhow.

That is good news!

I'm quite enthused by the wireless capbilities. I'm imagining camera glasses that are wireless, and bluetooth headsets.

I couldn't be more pleased, it's definitely a step in a good direction.

I looked more into batteries. It seems like the best rating is 3400 mAh per cell, so ~33% better than the new spec of 2200 mAh (x2). The best chinese prices and performance are lies. As for the new sensors : I am learning about kalman filters and such. No idea on deliverable code. Eventually should ...
