Yep that Deepspeech stuff is big, start smaller? https://realpython.com/python-speech-recognition/ OK, of your speech recognition is only the frontend to a web-based service, it may work. But it is not smart, you are feeding these systems with all your personal data. Some limited SR, recognizing a ...

What is the result if you swap the SD card from another, working, Pi Zero W into the current one?

I had that with an ill-formed wpa_supplicant.conf.
Try to copy a known working one to the boot folder.

You will probably find some CAN interfaces listed for the Raspberry Pi, but all current cars are using so narrow-timed protocols, that they can only be managed by a dedicated CAN controller. Just my few cents... You may be able to get the very basic functionality in compatibility mode, but not much ...

I'm relatively new to Pi but have experience with arduino and electronics so should be able to figure it out... OK, me too, but that screen is really not designed for Raspberry Pi, you will not find any library and will have to do everything bit-banging by yourself. I am fairly experienced, but I w...

In my opinion, one of the reasons to teach computer literacy in the schools is because productive use of technology in the workplace depends more on the skill of the human than on the expense of the office computer. +++ And those, who have got the skills to think industrial and combine IT with elec...

Hey rin, if your Pi had handful of 1/8watts underneath like LTolledo then start rehearsing Bye Bye Pye song. IMO spacers are good for mounting stuff like SSD or plastic or aluminum plate but marginal protection by themselves. Of course depends on the environment so YMMV. BTW I found using just bott...

I am trying to use a raspberry pi, to run parts of menu screen on several monitors.

With XRDP and a good remote computer, you can run many instances of the desktop, each one providing an own monitor.

If you have a Pi4 it has now got five UARTS. The additional ones are real UARTS, much better than the mini UART. Additionall hardware UART on Raspi 4: To enable UART2, add the following entry to /boot/config.txt under section [pi4] (with sudo rights). dtoverlay=uart2 save. You have then got: [ 0.000...

You would be much better off buying a display made for the Pi. That one is nothing for beginners...

"Please ensure you have the required CUDA dependencies." Rats, something that uses NEON? Adding "PDM" is interesting too. Stereo digital PDM microphones are an easy interface to Pi's. I have strong doubts the ARM processor of a Pi4 could fit... I would not spend a lot of time trying... Do use DNS d...

That is NOT a catch22 ! The Pi used as a master may very well have a monitor/keyb/mouse attached. It must not be the same model e.g. an Pi3b+ or a Pi3a+ which do not need any extra adapter will perfectly do. With one of them you start a Pi Zero W or a Pi4 effortless an intuitively without need for a...

If anyone fancies having a go at this (or any stuff they think is useful), they are more than welcome. We like good ideas, especially when others do the work that we don't have time to do.

I have promised to try and I'll do my best.

And just to mention: the absolute easiest way to set up Raspbian Stretch headless is to use another Pi having WiFi + VNC or SSH enabled: Take notice of its hostname. Clone the card with SD copier, Shut down the master Pi Put the copied card into the new Pi, Boot the new Pi, VNC or SSH into it invoki...

What is the first thing that you should do when you get a new Raspberry Pi 3 or 4 and want to begin tinkering? The very first thing is at least to put the Pi on 4 spacers ! The bottom of the Raspberry Pi has got a lot of very tiny components that are just unprotected. If you leave the PCB on your de...

I am quite a noob to raspberry pi and I am only just getting my head around it, until I accidentally short circuited the ground and 5v gpio pins with a piece of metal that I hadn't noticed was on my desk, as a result the usb port stopped working and I have since had no way of moving the mouse or ty...

Fair enough, but even so, should we be writing software for other people for free when we are massively overloaded with work anyway. As above, this is possibly all stuff that could be done by the 'community' and if it were, we would always look favourably on merging it to our own repos if asked. Th...
