Thanks topguy, that worked! I used the guide https://blogs.msdn.microsoft.com/virtua ... yper-v-vm/ i.e. edit the grub file to set the resolution: sudo nano /etc/default/grub I changed the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash plymouth.ignore-serial-consoles" to be: GRUB_CMDLINE_LINUX_DEFAU...

I'm running the Raspberry Pi desktop as a virtual machine in Microsoft Hyper-V, but cannot change the screen size from 800x600. I know VirtualBox and VMware have guest additions which help, but unfortunately I must use Hyper-V due to company security policy. Any ideas how to change the screen resolu...

You have a tight loop here: while (GPIO.input(RCpin) == GPIO.HIGH): reading += 1 which will cause the 100% CPU usage. You could put a small delay in this loop to give the CPU time to do other things. e.g. while (GPIO.input(RCpin) == GPIO.HIGH): reading += 1 time.sleep(0.05) I'm not sure the other sl...

Very impressive use of space on your workbench! I wish my own wiring was as neat!

StevenP

Just tried your suggestion, moved paho.py and payo.pyc into a sub-folder, and it runs now from the original folder!

Many thanks for the explanation, B.Goode - I had thought I was going mad...

Cheers,

Hi, I've been trying to get paho MQTT working on my RPi Zero for a couple of days, but just cannot get past an import error message: <see bottom of this post for a solution I just found!> import paho.mqtt.client as mqtt ImportError: No module named ''paho.mqtt"; 'paho' is not a package I thought I'd...

That's a great writeup, RobbesUK very comprehensive and clear!
Cheers, Steven.

Great project, I made a similar device to play scary Halloween mp3 clips - a random choice of 25 clips. My code was also similar, but there was one small improvment I used to avoid hard coding the filenames into the program. Instead of: scarefile = ["15.mp4", "16.mp4", "17.mp4"] For your example, it...

I know there are a lot of Raspberry Pi s in Germany, many colleagues of mine have them. So, is everyone reading a diffferent forum to this one - on a different website maybe? :cry: If anyone can let me know where best to contact German RPI owners about organising a Jam in Kassel I would be very grat...

Hallo, hat jemand Interesse mir zu helfen, um ein kleines Raspberry Jam in Kassel zu machen? Ich bin ziemlich enttäuscht dass so wenig Jams in Deutschland passieren. Besonders im Vergleich zu England (meine Heimat).. Das Jam soll nur klein sein - vielleicht 3-5 Raspberry Pi mit Bildschirm usw. Viell...

Good point, I was not aware of that in the ARM: https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=147781&start=50#p972790 It seems if the supply voltage drops below 4.63V then Turbo mode is turned off. So if mom's vacuum cleaner was drawing so much power from the electricity mains that the RPi...

A computer's speed it determined by its crystal controlled clock. How this is configured may change with processor loading and/or its temperature. The power supply voltage does not have any influence on the speed of the computer. So as far as the power supply is concerned, the computer is either wor...

Thanks Topguy, I had read that post.

Just to reconfirm - has anyone a currently working Amazon Prime Video AddOn for RPi Kodi?

StevenP

I know this is a common question, but thought it's worth asking again.. Has anyone a currently working Amazon Prime Video AddOn for RPi Kodi? I tried installing the Amazon Prime Video AddOn from the XLordX Repo - as described in http://www.kodireviews.com/amazon-prime-addon/ It all went well, but wh...

Hi, this is how I used Picospeak in Python. I wrote a function to make it easier. The example below speaks a string, and then a string and the time. Make sure you get the python indents right, of course. import subprocess import time def picoSpeakWait( text ): "Function to speak using Google Android...

Hi guys. Are those TTS (eSpeak, Festival and Pico) applicable on Rpi3? And is there any suggestion for a better offline STT as well? If so, please give me some simple codes in applying it to python. I'm just a newbie. Hi skumberly, compatibility between the RPi hardware versions is very good - they...

StevenP

OK, sorry I did not realise it was Dallas one-wire, although you are using it with separate 3V3 which is a very good idea. As rpdom said, the star topology will be the worst, a daisy chained the best. I had a look at the Dallas datasheet, the device is OK with sinking 4mA. This means they will be OK...

StevenP

You can check if voltage drop at the end of the cable is a problem by measuring the supply voltage at the sensor itself. It should not be too much less than 3.3V. Another possibility is the capacitance of the cable, causing the rise/fall times of the I2C waveforms to be slowed down. You could check ...

StevenP

Yes, but it depends what language your program is written in. Some kind of wait command is probably needed. You could also put that part of your program in a separate thread.

What language are your using?

StevenP

You said "The Pi is attached to a wood panel behind the TV using velcro". ESD (electrostatic discharge) is a big problem for any electronic equipment and since the RPi is not in a case then it will more susceptible than other consumer electronics. Anything which generates ESD could kill the RPi and ...

Hi,

PiHut has this device which converts both video and audio from HDMI to VGA and 3.5mm audio jack:

I just reread you message - But as you want SCART that doesn't help much, sorry!

StevenP

Have a look at Espeak, Pico or Festival as an alternative to Google's online TTS.
Here is my webpage about this:

http://elinux.org/RPi_Text_to_Speech_(Speech_Synthesis)

They all work without any internet connection, unlike Google TTS. I use Pico currently.

Cheers,
Steven

Great news about the German version of Magpi magazine! As a British ex-pat living in Germany what we now need here are many many more local Raspberry Jams! Germany is a big place and just having one or two per year covering the whole country has very little impact. If anyone is interested in helping...

Hi All. I edited my script to the following URLs and all is hunky-dory now.. :lol: (I was getting a bit fed up with listening to Classic FM all the time :mrgreen: ... great to have Radio 2 back!) Works fine with MPC/MPD at 128kbps MP3. Cheers, Steven, radios["BBC Radio 2"]="http://www.radiofeeds.co....

Hi All. The BBC international (and national too?) streaming links are changing. Radio 2 does not work from Germany with my MPD player since a couple of days. On the BBC website they mention they are stopping WMA and moving to AAC only. However MP3 will be supported for year or two apparently. I was ...
