Re: Sight for the Blind for <100$

Peter, I agree that the dimensions are not of a cellphone ( I just want to keep it as small as possible), and I also agree with not wanting rotation about the axis where it hangs. In the next version I will be extending the width by the minimum possible (still TBD). I am also considering converting ...

Re: Sight for the Blind for <100$

Quick votes for case redesign? I got the new battery. No matter what, I have to increase the depth of the case by 2.5-3mm bringing the total depth up to about 40 mm. I have two choices for the other dimension. I either make the case wider, or I make it longer. The width one is not necessarily bad be...

Re: Sight for the Blind for <100$

I added a face detector and early attempt at localization on the repo on github. I don't think I installed anything strange along the way, but I sometimes get caught up and forget. If you install: webcam_face_detection folder plus contents and facedetect.py and the updated version of menu.py it all ...

Yes, I recently referred Rich to the After-Sight project when he was inquiring about an ultrasonic emitter. Rather than having yet another open source project for a device for the blind, I suggested joining forces if possible and meaningful. Maybe a Sonic-Eye-like device could be used to offer a cr...

Re: Sight for the Blind for <100$

I'm a little bit conflicted about what to use as a respository. I jumped in with both feet to use github because it was something that I had seen successful projects use. I respected those projects, and the price isn't too bad (about $7/month). However I'm not too impressed with some of the changes ...

Re: Sight for the Blind for <100$

Peter, I agree with you about keeping it as functional as possible on the broadest range of hardware possible, that is why I added the support for USB keypads to mimic the encoder. As I add more hardware, it will just mean more error checking routines to keep things in check for those without. If al...

Re: Sight for the Blind for <100$

I do like that odroid board. It has nice specs. The extra ram/cpu/gpu/64bit is very attractive. I'm of two minds on this subject. On the one hand, I fully agree that it would be valuable to develop an alternative just to ensure as much single board computer cross compatibility as can be found. On th...

Re: Sight for the Blind for <100$

I've been away for a few days, and am just running the new code. It seems to be running well, and does nice detection of when the camera is accidentally pulled out. This is something that I found happens all too often. In the next case models I am definitely removing more plastic near the USB plugs....

Re: Sight for the Blind for <100$

Looks like I got a little too excited. Running into problems with this. Looks like I need to release the camera properly before I can restart it. I've tried camera.stop() hoping that the WebCamVideo.py would do a good release. That didn't pan out. I'm currently investigating WebCamVideo.py to see ab...

Re: Sight for the Blind for <100$

as for the SD card issues, I have had no problems personally. I would just suggest trying again with a larger capacity card. Although the image might fit on an 8GB card, not all 8GB cards are created equally. Maybe your download was corrupt? If you are already doing it on a 16GB then all I can say i...

Re: Sight for the Blind for <100$

I will start with Peters: 1. Default visual (auditory) contrast with raspivoice appears quite poor (just compare it with The vOICe for Android on curtain folds or whatever), and a menu setting to improve contrast is still missing. 2. A long press in the settings menu makes the device speak that it w...

Re: Sight for the Blind for <100$

I will see about obtaining a problematic camera to help solve these issues. It will no doubt take a few weeks just to get one of the logitech ones via ebay. In the meantime, I'm sure we can have try/catch routines for starting up the camera that can retry with a timeout period. This might be enough ...

Pranav, 1. Yes it does. To run both programs, from the main menu the options are 'toggle raspivoice' and 'toggle teradeep' After you launch one, you can still navigate the menu system and just toggle the other program on. I have found they work quite well together. 2. That is correct. In migrating a...
