Re: Sight for the Blind for <100$

Unfortunately, the first two prototypes had the old power board. It can only charge at 500ma No problem. If it is indeed expected behavior for the prototype that I have then it is fine with me, because I will just take it into account while planning for testing. Today I was still studying possibili...

Re: Sight for the Blind for <100$

Pretty excited! The new power board seems to have jumped the gap between discharge and charge during use. The supplementary pack appears to be discharging first while maintaining the internal battery of the device. Today I was testing the device for a few hours without the USB charger connected. Ob...

Re: Sight for the Blind for <100$

If flashing the new image on the card does not work, you may have a hardware problem of some kind. Maybe. I got tired of each time walking to my router to which the Pi was connected via an ethernet cable, so I used that same cable to connect the Pi directly to my PC. That gave me the "Network error...

Re: Sight for the Blind for <100$

Thanks, I had already tried those settings but unfortunately they did not work for me. As of today, things are worse, as I consistently get "Network error: Connection refused" when trying to connect to the Raspberry Pi via PuTTY, despite the fact that its local IP address and device name are visible...

Re: Sight for the Blind for <100$

Thanks again. The --read_frames=7 indeed works well, and greatly improves lag. I'll probably be using it in combination with --sample_freq_Hz=16000 to reduce load. Then restart raspivoice with the flags of your choosing, but not the sound menu at the same time as preview. The Raspberry Pi desktop sh...

If you install xming on your pc, and do x11 forwarding with putty, you can get the video output of th pi on your pc.

Peter: If you want to see the change with this, it would be a matter of editing the /etc/rc.local file on your device and adding this to the raspivoice execution line prior to the & symbol at the end of the line. To disable the vibration on startup, you would have to edit the file /home/pi/rangefin...

Re: Sight for the Blind for <100$

I believe the current behaviour on camera disconnect is a crash of raspivoice. Upon a physical camera disconnect while video is still streaming, a crash is to be expected on all platforms. However, on Android and only with these TX-25 glasses, even quitting the app after properly closing the camera...

Re: Sight for the Blind for <100$

Thanks for the info. A few more observations/suggestions: It looks like the same lack of contact debounce also affects rotation of the wheel, resulting in spurious multiple option announcements and some delay in knowing which option the wheel is at, because any (noisy) contact changes get buffered a...

Re: Sight for the Blind for <100$

To disable vibration hold the pushbutton in for 3-4 seconds. Brilliant. Now I can further test without creating a haunted house. :-) One issue that I initially ran into is that the case hole for the headphones connector was a bit too tight for the plug of my Sennheiser PC 3 audio headset. Not fully...

I do welcome criticism, so when you get your units, please make a list of changes you would like to see. Some will be possible, but some won't. Just received the prototype, thanks! It appears to work properly, and I hope to start doing some more testing tomorrow. I will report about my observations...

Re: Sight for the Blind for <100$

This week I received the glasses from eBay that looked identical to the Technaxx TX-25 camera glasses. Not only are they a lot cheaper at $60 to $70, but the pair that I received was not affected by the garbled bottom slice that I reported about for my TX-25 glasses, so it confirms that that was jus...

Re: Sight for the Blind for <100$

The idea here is that different people want different kinds of information. I agree with the need to address multiple audiences. Still, it can be difficult to draw significant interest.

Re: Sight for the Blind for <100$

As a novice using the vOICe software, even I could easily detect the edge and angle of the platform that represents the kind she fell off of in this picture. What if the 'better barricade' is the better ability to perceive these details? Thank you for sharing the information and your thoughts about...

Re: Sight for the Blind for <100$

A question? if a parallel mode was used, you could shift the vOICe output to one ear, and use the other ear for the teradeep identification? I don't know if thats getting too confusing for the listener though... No that would not work well. The stereo panning intuitively supplements time as a means...

Re: Sight for the Blind for <100$

I'm fairly certain that they won't both operate at the same time. I realize that it is probably well beyond the processing power of a Raspberry Pi system, but it could be great to have The vOICe and talking teradeep software running in parallel, as the teradeep descriptions might serve as training ...

Re: Sight for the Blind for <100$

The user manual of the TX-25 glasses at http://www.technaxx.de/download/download.php?filename=803.pdf lists a power consumption of <0.8W. We need only 320 x 240 images at 1 fps, so a low duty cycle could in principle save us a lot of power, but I'm afraid there are no technical options that let one ...

The glasses work with the default settings (I see no garbled slice on the preview). I hear no garbled slice in the soundscape. I haven't played around with changing the resolutions on linux yet because I've been trying out v2 of the PCB. Good news indeed. If your TX-25 glasses show no garbled botto...
