Re: Can a Pi be used in some way to prevent Dementia sufferers making landline calls to a specific number?

Running a small PBX such as asterisk and connecting the phone to an ATA which in turn connects to the PBX with a total convert to VoIP is certainly one solution where the RPi can be included, but not one that sounds right for you or optimum. Stepping back for a moment, there are two types of call re...

Re: Large print in terminal

As well as increasing the font size, decreasing the resolution I also increase the actual display size. I use a 32" HDMI TV as a monitor and find that the amount of head turning is acceptable. put the three together and you may find a good compromise.

Good luck

Re: Getting started on Raspberry PI with low vision

I used to use compiz zooming on a ubuntu virtual desktop many years ago and found it really useful but a pain to setup. According to the compiz WIKI page fro Debian you use the windows key (super-key) combinations very similar to zoomtext. If its not working I would look at the settings of the WM an...

Scanning, OCR and reading the page using a RPi

Hi All, I am working on a project that has so far provided an initial standalone image for use with a RPi. It allows a blind or low vision user to read a flyer, a letter or perhaps a beloved recipe using a cheap USB scanner, a raspberry Pi, a mouse to start the scan and a headset or speaker plugged ...

Re: Non-functioning Audio and Speech

Thanks all, I can confirm taking things slow and easy one change at a time and testing again after each channge that on occasions the sound stops working through the jack and returns to HDMI. if I reissue the force to jack command and make no more changes it stays put on the jack. so the issue is to...

Re: Non-functioning Audio and Speech

A quick update using the command

Code: Select all

amixer cset numid=3 1
Does allow the speaker-test audio to work through the 3.5mm jack, auto certainly does not work, I can live with that.
Onto the next test which is to install eSpeak and see if that works on the latest RPi build .

Regards
Paul

Non-functioning Audio and Speech

Hi all, I am in the midst of a project for my peers at the Blind Low Vision NZ where I use a RPi and AWS to get the Amazon Echo to initiate a scan and read it back on demand to the user. I have a prototype functioning and have demonstrated it to much delight to the charity. As many blind folk are al...

Re: RPi access point using cheap RTL8188 based dongle

Do you mean a client mode wifi? if so not with the script, it was always apparently easy for people to get the adaptor working as a client. This is something I would use from a point where I decided I wanted the access point ability on the RPi image. if I decided I did not want it I would return to ...

Look at the script and perform the actions manually, you are closer to the end then the beginning

its a real shame that the http://www.jenssegers.be blog post was not available when I needed it last year, oh well good to know there is a source for the hostapd binary.

Re: RPi access point using cheap RTL8188 based dongle

I assume you mean the DHCP server, I am also assuming that you have installed one on your RPi? the best advice I can offer is as a general rule you can throw your search net on goggle out wide looking for Debian answers or even Ubuntu ones, it is only in a small number of cases that the hardware or ...

Hi robbo100, I have no idea about any other realtek drivers other than then one stated the 8188CUS, many of the newer wifi adaptors are fine with the default configand api hooks offered by the modern hostapd package. There is a check part way through the script that assuming I got the logic right wi...
