Re: Sight for the Blind for <100$

FYI: Wired yesterday discussed Baidu's DuLight, a device based on deep learning neural networks that appears functionally very similar to what is being developed here for Raspberry Pi using jetpac/deep belief/teradeep and also similar to BlindTool for Android, http://www.wired.com/2016/01/2015-was-t...

Re: Sight for the Blind for <100$

Hi Mike, Great to hear that you got your finger on the sore spot. Yet I think it needs to be taken one step further, because applying magic numbers like dropping 30 frames sounds like it is going to break for any of a number of reasons, such as a different capturing frame rate, a future different Ra...

Re: Sight for the Blind for <100$

Hi Mike, Yes, libccv2012 worked a little better for me. Last night I was hampered by the battery being low, causing jetpac and all speech to stop, making the device unresponsive to a shutdown request, which in turn led to a corrupted filesystem when forcibly turning off power. Anyway, I reflashed th...

Re: Sight for the Blind for <100$

I successfully downloaded the image from the same link that Pranav used. After unzipping I flashed it using Win32 Disk Imager. A first test indicates that it works without major issues on my prototype system. Raspivoice appears to work fine as before. I tried the default Jetpac, but thus far found i...

Hi Mike, Does anyone know another easy way to share large files in a persistent fashion that is free? I do not know your compilation tool chain, but I suppose that your (zipped) sources add up to much less than 3.2 GB? If you have access (e.g. via Windows' Remote Desktop Connection) to some remote P...

I ran into something similar for Android the other day, where a new app named BlindTool wraps the MXNet deep learning framework. It speaks ...

Re: Sight for the Blind for <100$

Hi Mike,

Various web pages suggest setting

hdmi_drive=1
hdmi_drive=2
or
hdmi_ignore_edid_audio=1

E.g. viewtopic.php?f=28&t=48459

I have not tried any of this yet because I currently do not have the device set up for connection with my PC.

Hi Mike, One of the blind users of The vOICe tried your image on his own Raspberry Pi unit (not one of your devices), and it worked fine, with speech, and the soundscapes responding to changes in the camera view. However, next in working with a sighted friend he noticed that there would be no audio ...

Yes, I ordered one of these webcams today to verify UVC compliance and check on image quality. I'm also on the lookout for cheaper camera glasses that might prove UVC compliant despite the manufacturer not advertising that property. I gambled on a cheap pair today and should know in a few weeks if i...

Hi Mike, What do you think of the new Raspberry Pi Zero, performance-wise? Good enough for running raspivoice? http://www.engadget.com/2015/11/26/raspberry-pi-zero/ Ah well, just read that it is only 40% faster than the Pi 1, so that sounds less attractive, http://venturebeat.com/2015/11/25/raspberr...

Re: Sight for the Blind for <100$

Hi Mike,

Thanks for all the great work! There are many reports on the web that cheap Chinese battery packs often have a much lower capacity than claimed by the vendor (even down to 10%!), so that could have been another factor in Pranav's shorter-than-expected battery life.

Re: Sight for the Blind for <100$

I have just tested what you described. A Rasbperry Pi V2 with no electronics board, with glasses, powered through the normal power port on the rpi board works fine. I guess that is to say it degrades gracefully. Only caveat here is that the image will only work on the V2 pi's because of the change ...

Since there are only a few errors,...
