I am using my Raspberry Pi 2 with an HDMI Monitor without Audio. In LibreELEC, I need to enable the Audio Output on the 4-Pole (TRRS) Jack so that I can feed it to external amplified Speakers. EDIT: I found the answer to this: It is in System/Settings/System/Audio Output and select HDMI and Analogue...
I was given a Raspberry Pi 2 Model B as a present and am having problems with the HDMI output flashing off and on about every 2 seconds. The Pi 2 boots up just fine using Raspbian (installed via NOOBS) and the text screen scrolls just fine until the GUI Screen appears .... then the screen flashes of...
Using the information gleaned from this thread, I am trying to edit the config.txt file to allow me to switch monitors. However, the file has protected access and will not let me save the edited file. In fact, the Folder seems to be protected because I cannot even save a copy of the original config....
This is a plea for a simple on-liner to be added to the NOOBS Setup page to alert the user to the CHANGE in the distro with Version 1.3.10 which only distributes Raspbian in the Download. Under the Header First Boot between instruction 1 and 2, it should say "If you want to install other Operating S...
No. In the context of Overclocking, overvolting refers to raising the ON-CHIP generated voltage driving the System-on Chip Processor. The 5V input to the RPi is stabilised at 3.3V on the Board and this lower voltage drives everything on the SoC. Other voltages may be derived on the SoC and the Proce...
No your maths is seriously flawed. The energy stored in a Capacitor W = CV^2 so the voltage across the capacitor will decay rapidly as power is drawn from it. The RPi needs >4.75V to operate and therefore its operation will becom unprecictable below this voltage. In contrast, an LED will operate wit...
Make sure that you use a good quality USB A to MicroUSB cable if you are powering the RPi through the MicroUSB port. Many cheap cables are fakes and have very high resistance causing a large Voltage drop and consequent problems.
I suspect that the two Battery packs are identical except that the 2A one has configuration resistors on the USB Socket data lines to allow an iPad to draw up to 2Amps from it. The Display does not specify its supply Voltage but being designed for in car use, I suspect that it is designed for 12V, Y...
Yes, Scratch is a very intuitive tool for getting children started with the concepts of Programming. The grouping of the Control, Actions and I/O commands facilitates a very rapid uptake of the concepts of loops, conditional branches, interrupts etc.. I let my 9 year old Grandson loose with it and a...
There have been two releases since then. Try downloading the latest release which is more stable but Scratch still freezes occasionally. Try NOT to play sounds more frequently than every three move or rotate instructions. I think that Scratch sometimes overflows the sound DSP stack which caused it t...
I agree, I already have a working setup where the power supply is plugged straight into the USB hub and from there a USB to micro USB cable to the power socket on the Pi. However it negates the purpose of my little experiment. I don't see why I can't do what I'm aiming to achieve? What does the pow...
What are you powering "through" the RPi USB, GPIO and HDMI Connectors? THe problem with powering all of your peripherals through the MicroUSB connector is that you are likely to encounter excessive volt drop through the F3 Polyfuse. Also, many MicroUSB cables have exccessively high resistance conduc...
I have not tried SSH-ing into the RPi without first enabling SSH in the Config.pi screen so must assume that it is NOT enabled by default. The Rasbpi Config screen appears when the SD Card is first booted. It is a sequential list of about 8 options that can be selected and parameters for that option...
Hello. My first Raspberry Pi is on it's way to me in the post. Although I've been a professional programmer for 20 years and hark from the days of the first 6502 based home computers, I'm now totally blind. Can anyone tell me if SSH is now enabled by default in the latest Raspbian images? I have do...
This one works out-of-the-box and ships from a UK location so you will get it in a few days. It can be bought from Hong Kong or China sellers for a quid cheaper but will take up to a month to get to you.
That is because you are only seeing the Boot partition, the main partition being ext4 format and invisible to Windows. If you are putting a new Image on the card using Win32DiskImager, just let Win32DiskImager overwrite it. It will do the re-format on the fly. If you want to use the card as a FAT da...
